Operate the method in metal casting workshop, perform the system of the method and comprise the metal casting workshop of this system
Technical field
The present invention relates to the method for operation metal casting workshop (particularly green-sand metal casting workshop) and the system for performing the method.The invention still further relates to the metal casting workshop comprising this system.
Background technology
Technology for the automatic operation of foundry is well-known.US5125448 discloses a kind of Casting Equipment automatically, senses the information of the characteristic about each independent mould wherein in moulding machine, and is used in for controlling motlten metal in the downstream cast unit of the cast of the mould involved by this information.This information disclosure is for relevant to following factor: whether mould-type, core have been placed in a mold, whether mould is that suitably whether firm and mould is not suitable for pouring into a mould due to other reasons.This information can be used to become suitably to locate pouring nozzle relative to mould by cast unit controls, or be controlled to the particular mold of not pouring into a mould this information and relating to.Then, thered is provided about particular mold whether by the information of the information of pouring into a mould and the weight about this particular mold by cast unit, and these information are used for control to water unit, should to water unit for guarantee to leave the extraction station of breaking mould molding molding sand in the suitable water yield.
Method described in US5125448 neither minimizes the environmental disturbances also do not measured caused by foundry operates, but the information only paid close attention to based on the characteristic about each independent mould guarantees failure-free operation.
In addition, WO89/09666 discloses a kind of method for evaporating casting and equipment.By evaporation model location in a reservoir.By the compacting of molding medium around it, and this container is positioned at below cast unit.When poured with molten metal is to container and when evaporating this model, use the gas that vacuum pump is produced by this model.Pressure in this container is measured by pressure detector, and for the regulating valve that is operatively connected to this pump and vacuum buffer container.The flow velocity of motlten metal is controlled by controlling this pressure.Method described in WO89/09666 neither minimizes the environmental disturbances also do not measured caused by foundry operates.
KR20120055925 discloses a kind of local ventilation equipment and a kind of many bell-types local ventilation method for changing air pollutants.
DE102009031557 discloses a kind of method using heat exchanger to collect heat from continuous casting process.
In recent years, owing to operating to foundry be mutually related environmental disturbances and more and more paying attention to and providing the needs of a home from home for the workman in metal casting workshop the challenge of society, metal casting workshop has become more and more payes attention to such environmental disturbances.
Some the maximally related environmental disturbances relating to the operation in metal casting workshop comprise air pollution, CO 2(carbon dioxide) discharge, heat, noise, energy consumption, water consumption and such as useless molding sand, useless bentonite clay and abandon the waste product of foundry goods and so on.Useless molding sand and useless bentonite clay can not reclaim, and must abandon.
In addition, waste product also comprises and is not the parts of final casting and the parts be formed in running channel and rising head, the accumulation thing namely in mould, and they are for guaranteeing the suitable casting of motlten metal and solidifying, and guarantee that they are just separated with foundry goods once foundry goods is separated with mould.
In addition, for the raw material (it can be regarded as environmental disturbances) of metal casting plant operations comprise metal consumption, Novel sand and new bentonite clay consumption, for the formation of green-sand any depletion of additive and run machine or Compressed Gas or the steam consumption of heating be provided.
Often kind in these environmental disturbances relates to the one or more unit operations in metal casting workshop.As embodiment, green-sand cast molding (wherein using the mould or model that are manufactured by molding sand) extensively adopts and provides green-sand, green-sand is formed green-sand mould, by poured with molten metal in green-sand mould, allow motlten metal to solidify, from foundry goods, remove green-sand mould and make green-sand to adapt to the unit operations of recycling.
The air pollution of dust and fine particle form typically relates to manipulation and uses the unit operations of green-sand, namely provides, formed and removes.In addition, in the used silica containing situation of molding sand bag, when the molding sand in mould is melted Metal Contact then during by poured with molten metal to mould, the silica dioxide granule thing of submicron-scale may be formed.Such particle may cause workman to suffer from silicosis.Therefore, metal casting workshop needs to spend sizable energy on dust collection.
Dust caused by the different units in metal casting workshop operates has different material and heterogeneity, and such as may comprise metal or metal oxide.
Air also may pollute by burned thing (such as carbon monoxide and/or VOC (VOC)).
Many unit operations in metal casting workshop are at internal environment (environment namely in metal casting workshop) and external environment condition (environment namely outside metal casting workshop) both middle generation smell or smog.These smells and smog may make us unhappy or harmful breathing.
Air in environment outside metal casting workshop also may by the sulfur dioxide of the fuel (for heating the smelting furnace for deposite metal) from such as coal, oil or natural gas and so on and nitrogen oxides pollution.If the metal that will be melted comprises discarded metal or Footwall drift block, then the paint on these metal derbies and coating may cause air pollution because of such as dioxin in metal casting workshop.In addition, the finishing process of foundry goods such as polishing and welding and so on also may discharge toxic metals particle in air.
Heat relates generally to casting molten metal and the unit operations allowing it to solidify.Heat also discharges from the smelting furnace for deposite metal.Heat may cause that the workman in foundry dewaters, heat cramps, heat exhaustion and heatstroke.Workman is the cataract that caused by the infrared of motlten metal radiation and ultraviolet rays of PI also.Also burn may be caused from the splashing of motlten metal and spark.
Noise may relate to any unit operations, and may duration very short (such as from shock) or duration very long (such as from the noise of vibratory shakeout machine).Modal noise source is from moulding machine, vibratory shakeout machine and the finishing operation such as spraying molding sand cleaning, carbon arc air gouging, casting cleaning and decoration and so on.The general boundary of noise is between about 80 and 110dB (A), but some noises may up to 116dB (A).Another noise source is from use compressed air cleaning mold or noise mold materials being imported moulding machine.
Although individual hearing protectors can be used, the noise very short for the duration does not use them usually, but short duration noise is added to and exposes the entirety of noise, that is, integrated environment impact.
Closely related is vibration in noise, and this vibration not only may affect workers ' health, and may affect life-span of metal casting machine, performance and maintenance requirement, thus finally affects the efficiency in metal casting workshop.
CO 2discharge is usually directed to melt the energy required for metal that will use in foundry and run required for machine (such as molding sand moulding machine, mould conveyer, vibratory shakeout machine or molding-sand cooler), required for performance element operation energy.In addition, the energy of the ventilation that metal casting workshop is provided also is needed.
Water consumption relates to removes green-sand from foundry goods, makes molding sand be suitable for being provided good molding sand molding during molding in molding sand moulding machine, for such as being formed at vibratory shakeout machine place restriction dust, and for cooling.
In addition, water consumption can cause the waste water needing appropriate preferential treatment usually.Such as, waste water may contain metallic dust or organic compound.Waste water also may absorb the pollutant from discarded metal or slag due to rainwater and be exuded to ground, and is caused by the scrap metal thesaurus ground outside metal casting workshop storing slag.
All unit operations need energy to perform.
Production waste relates to formation molding sand, casting molten metal, removes foundry goods from mould and makes molding sand be suitable for the unit operations recycled.Production waste also relates to control foundry goods to detect beyond economic repair misrun casting, that is, foundry scrap.Waste material can be melted usually again, but under the certain situation must disposed in refuse landfill at slag, waste material is also equivalent to slag.
Among these environmental disturbances, air pollution, heat and noise major effect workman environment, and CO 2discharge, energy consumption, water consumption and production waste major effect are around the environment of foundry.Energy consumption, water consumption and production waste also affect the cost running metal casting plant operations.
" incorporated pollution prevention and the control reference paper about the best techniques available in forger and foundary industry " be set forth in further from European IPCC office of the ambient influnence in metal casting workshop was found in (in July, 2004).
In order to reduce the ambient influnence be associated with operation metal casting workshop, CO 2discharge, energy consumption, water consumption and production waste should be preferably low as far as possible.
In addition, in order to provide applicable workman's environment for the workman in metal casting workshop, air pollution and noise should keep low as far as possible, and take measures to prevent heat from foundry, causing too high temperature.
Meanwhile, the effective production providing foundry goods must be run in metal casting workshop.Such as, the number of beyond economic repair misrun casting must be low as far as possible, so that the number of the available i.e. castings of time per unit and environmental disturbances amount is high as far as possible.If this is because must to abandon or the foundry goods of scrapping that melts again abandons and just represents production waste, and if again fusing just represent and need energy, i.e. heat.In addition, even if when foundry goods can be made castings by machine, such as, if foundry goods owing to causing the half mold mispairing of defect in the foundry goods of the defiber of contiguous mould, and there are light defects, then such mechanism or cleaning need energy and labour, and the workman in metal casting workshop or operator may be exposed to arduous or unsound working environment.Therefore, keep the number of the available i.e. castings of time per unit and environmental disturbances amount high as far as possible, at least minimize to relate to and scrap foundry goods and those environmental disturbances of energy for melting again.
Therefore, obtain good internal environment (namely to the low-level environmental disturbances of the workman in metal casting workshop) and good external environment condition (namely to the low-level environmental disturbances of the environment outside metal casting workshop) very important.In addition, should be low as far as possible to the environmental disturbances aggregate level of internal environment and external environment condition.

Claim 4, about the step obtaining at least one instruction described, defines the embodiment of the different benefits of method according to a first aspect of the present invention.At least one threshold value is used to be the straightforward procedure of ambient influnence of the operation reducing metal casting workshop, because threshold value is easily arranged.
Depend on measured environmental disturbances, at least one threshold value described can be the upper limit or lower threshold.At least one threshold value described should be chosen to limit such level: at which level, environmental disturbances causes being harmful to the workman in metal casting workshop or the environment of operator, or environmental disturbances welding or cause defective casting.
At least one threshold value described manually can be arranged by the workman of metal casting workshop and/or metal casting machine or operator.At least one threshold value described also such as can carry out Lookup protocol by carrying out calculating according to certain algorithm.Such as, at least one threshold value described can be set to the product of the mean value of at least one measured value described of a factor and at least one environmental disturbances described in the month before, during last week or the previous day, thus at least one threshold value described automatically can be updated at least one environmental disturbances described at least one measured value described in the month before period mean value such as 110%.At least one threshold value described can alternatively be arranged so that the estimate of the accumulation of at least one measured value described in some future time sections of environmental disturbances cause total environment disturb be in a certain amount of under.In the synergistic situation of existence first and second environmental disturbances (such as there is the synergistic heat to workman's environment and noise), or there is higher priority (namely first or second environment interference, remain on by relating in tolerance interval that the threshold value of measurement that second environment disturbs limits compared to it, it remains in the tolerance interval that limited by the threshold value of the measured value relating to described first environmental disturbances more important) when, threshold value for the measured value of first environment interference can in addition by the impact of the threshold value of second environment interference.
At least one threshold value described can instruct according to official further or regulation is arranged.Such as, about the air pollution of plumbous (Pb), the defined threshold in air is 50 μ g lead/m 3.About in the further embodiment of lead, to instruct or regulation arranges more high threshold according to official, described more high threshold is 50-75 μ g lead/m 3with >75 μ g lead/m 3and require to use personal safety equipment, and check the health of workman respectively.As the manganese (Mn) of the additive in the metal casting workshop for cast steel and special steel, have about can the 0.1mg/m of manganese of respiratory form 3official's threshold level of air, and about the 0.2mg/m of the manganese as smog, dust or powder 3the threshold level of air.Manganese is hypertoxic, and can cause brain and neural serious and irremediable damage.
At least one comparative result described can be the value that instruction at least one measured value described is how different from least one threshold value described, or it can be whether instruction at least one measured value described is in by the Boolean at least one threshold value described and the measured value limited range when the inoperation of metal casting workshop.When at least one measured value described is direct measured value, at least one threshold value described normally upper limit threshold, and when at least one measured value described is indirect measurement, at least one threshold value described normally lower threshold.
Search at least one instruction described in a lookup table very fast, and use the function that at least one comparative result described or at least one measured value described are operated, be provided for more different instructions of the more accurate of at least one metal casting machine described and microminiaturization operation.
Described look-up table can comprise measured value, and wherein each measured value is relevant to command adapted thereto.Instruction corresponding to certain measured value may by testing different instruction for certain measured value of environmental disturbances and by comprising the instruction reducing environmental disturbances most in a lookup table, determining by rule of thumb.How the instruction relating to certain measured value can will affect environmental disturbances alternatively by consideration different instruction, determines according to analysis.
In addition, the instruction corresponding to certain measured value is arranged according to the experience in past (namely by considering such as to increase in the past or last hour of the operation of certain instruction whether in metal casting workshop of current and so on or the previous day to vibratory shakeout machine to be performed for the measured value obtained).Therefore, when the operator in metal casting workshop or workman are provided for the instruction operating at least one metal casting machine described, this instruction of the measured value corresponded in look-up table can be arranged to the instruction provided by operator or workman, this instruction provides the measured value in the moment of this instruction corresponding to operator or workman.
In addition, dominant instruction when can be arranged to the operation of certain measured value described in metal casting workshop is stopped about the instruction of certain measured value in look-up table, when starting to make the operation in this metal casting workshop, when it stops with the operation in metal casting workshop, dominant instruction starts next time again.
Instruction defence manipulation is obtained about the abnormal environment interference outside the input value allowed of look-up table sum functions from the workman in metal casting workshop or operator.Then, the instruction that operator or workman obtain, together with the measured value of prompting from the instruction of workman or operator, is stored in look-up table for using in the future.
Look-up table can comprise the more than one threshold value for each measured value.Therefore, corresponding to the first threshold place of comparative result of little deviation showing measured value, the first instruction can be obtained.This first instruction may cause the little change of the operation in metal casting workshop.Corresponding to the Second Threshold place of comparative result of large deviation showing measured value, the second instruction obtained causes the large change of the operation in metal casting workshop.Second instruction such as can obtain from the operator in metal casting workshop or workman there.
In some embodiments of method according to a first aspect of the present invention, the method is further comprising the steps of:
Obtain the information about the operation in metal casting workshop; And
This information is used when obtaining at least one instruction described.
Whether this information such as can comprise the expection speed of production in metal casting workshop, the type of the mould for metal casting workshop, the number of the mould on mould conveyer, the weight of each mould, moulding machine and mould conveyer and run.
This information can be used for obtaining the instruction of active operation metal casting machine.As embodiment, air-polluting low value during can operation suspension being reflected in about the measured value of the air pollution/dust at vibratory shakeout machine place.In order to by ambient influnence, the method attempts to reduce water consumption further.When operation suspension, consign to vibratory shakeout machine without mould, thus vibratory shakeout machine does not produce dust, and this is the final water of cut-out completely consumption perhaps.Use this information; be in this case now such as by obtain about the mould produced by moulding machine information again the information that operates; supply water can initiatively be started to vibratory shakeout machine; when being delivered to there with box lunch first mould after operation has started again, there is the water supplying vibratory shakeout machine.Like this can air pollution detected and to vibratory shakeout machine supply water recover before, avoid from the first mould, discharging dust and air-polluting corresponding peaks suddenly.
This information can obtain from computer for controlling and/or from the operation sensor be associated with respective metal casting machine.
This information can be used as the additional input at least one measured value described to adjust the instruction obtained, or can be used for obtaining the instruction different from the instruction obtained based on measured value separately.
This information also can be used for arranging instruction or for arranging threshold value at look-up table.The more active operation in metal casting workshop may be caused like this.
The information of this information such as present speed that can comprise such as metal casting machine and so on, it can be derived from the current execution instruction of measured value or other metal casting machine.Therefore, this information such as can obtain from moulding machine for operating the instruction of moulding machine by analyzing at present.This information such as comprises the number of the mould of formation per hour.Then, this information may be used in a lookup table initiatively for the instruction of vibratory shakeout machine, and this instruction is known according to the experience in past and is suitable for keeping air pollution in threshold value.
Therefore, this look-up table can comprise for each instruction more than an input parameter.In order to demonstrate, this look-up table can comprise the first input of the measured value for environmental disturbances (being dust/air pollution that vibratory shakeout machine causes in this case).This look-up table also can comprise the second input of the number about the mould manufactured per hour, and the number of mould hourly is the embodiment of the information of the operation about metal casting workshop.Described first and second inputs can with prioritization, and such as, make first hour period in operation, vibratory shakeout machine can use the instruction of the current number being associated with mould hourly to operate.But after first hour, this vibratory shakeout machine can use the instruction be associated with at vibratory shakeout machine place air-polluting measured value to operate.In this manner, the better of metal casting machine and more robust operation is obtained.
Information about the operation in metal casting workshop may be used for the instruction obtaining metal casting machine (such as compressed-air actuated compressor).In this case, this information can comprise the compressed-air actuated aggregate demand for the metal casting machine in metal casting workshop.This information also comprises the pressure measuring value of the compressed-air actuated thesaurus for compressor.
