Description
Refractory brick high-temperature wearable analyzer is a kind of detecting instrument that is used to measure the fire resistive material anti-wear performance.
In refractory brick routine inspection project, also do not have relevant wear-resisting check, and refractory brick is in and works under the condition of high temperature, and constantly be subjected to the impact and the wearing and tearing of furnace charge in a lot of industrial furnaces at present.The lump zone in the State of Blast Furnace for example, the most of zone of the body of heater of rotary kiln all belongs to this type of situation, therefore, decrease under the environment at this high-temperature wearable, the power of the abrasion resistance of refractory brick will directly have influence on the life-span of stove self, and then have influence on the working rate of stove, be throughput rate, select the good refractory brick of high temperature abrasion resistance, with guarantee can be synchronous in other equipment generation life-spans prerequisite under prolong life-span of furnace lining as far as possible, prolonging the interval time of stove overhaul to the greatest extent, raise labour productivity, is that metallargist institute is solicitous, therefore, in the check of refractory brick, measure the high temperature abrasion resistance of the various refractory brick of existing material, it is in demand perhaps checking a kind of wear resistance at elevated temperature etc. of new material.
The goal of the invention of this utility model just is to design a kind of instrumentation that detects the refractory brick wear resistance at elevated temperature, can measure this index of refractory brick by shirtsleeve operation, and finally design the goal of the invention that the refractory brick high-temperature wearable analyzer of realizing has satisfied this utility model.
This utility model roughly is made up of five parts.Accompanying drawing 1 is the structure and the work synoptic diagram of this kind instrument, and accompanying drawing 2 is result of implementation synoptic diagram of each structure of instrument.The structure of each several part is in the accompanying drawing 2: the heating and the insulation room device (the following heating space that is called for short sometimes) 1, can rotate or translation execute mill apparatus (under the prerequisite that can not take in a wrong spirit, refer to specially also that later on refractory brick is exercised executing of grinding function and grind part) 2, the hold down gag 3 of refractory brick, instrument support (seat) 4, the instrument measurement and the display system apparatus 5,17 that link by sensor and each relative assembly are tested refractory brick sample.Between above-mentioned each device is to cooperate like this, can produce and keep be provided with in the heating space 1 of high temperature keep still under the hot conditions that it has certain grinding intensity execute mill part (as heat-resisting emery wheel etc.) 2, execute the mill part under the drive of motor, rely on different gearings, produce translation or rotation, the grinding that tested refractory brick sample 17 is carried out under the condition of high temperature, have a space groove on the heating space sidewall, make tested refractory brick sample can place among the heating space and at high temperature can with execute the mill part closely contact, the press member of the hold down gag 3 of refractory brick is added on after the refractory brick sample, its role is to the refractory brick sample with certain pressure, guarantee that the refractory brick sample is in the process of tested grinding, all the time can closely contact with executing the mill part, ground constantly, in the mensuration process, the various running parameters of instrument must show, as execute the intensity of mill, therefore temperature of heating space or the like is provided with instrument and measures and display system apparatus 5.Instrument support (seat) 4 is used for supporting instrument, and it mainly supports heating space and uses.
The utility model is implemented, the concrete structure of its enforcement as shown in Figure 2, existing in conjunction with the accompanying drawings 1 and Fig. 2 in the sign flag of each several part, further describe for this utility model.
1. heating of foregoing instrument and keeping warmth space device 1 are that the spatial enclosure 8 by the heater in temperature controller 6, the space 7, fire resistive material 9 and steel plate system constitutes.Heater according to certain programming rate, send certain heat, is raised to the temperature of drafting with heating space, and keeps constant under the control of temperature controller, and fire resistive material is in order to reduce the heat waste of heating space as far as possible.
2. the foregoing mill apparatus 2 of executing is to be made of High Temperature SiC emery wheel 10 and wheel shaft 11, umbrella gear 27 and varying-speed motor 26; under the drive of motor; realize the rotation of emery wheel; the top of grinding wheel spindle 11 has 12 pairs of grinding wheel spindles of cooling device to cool off; 15 and 16 is that the orientation of grinding wheel spindle is fixed and protective device, the 28th, and reinforcing member.Because motor is speed governing, under the control of speed regulator 24, carry out speed governing according to Testing requirement, to satisfy different measurement purposes, the speed adjustable range of the motor of use is at 0～90 rev/min, 13 and 14 is the electrooptical devices that are used for measuring the actual revolution of emery wheel, shadow shield 13 rotates with grinding wheel spindle, whenever goes around, and the light that the light source 30 of photoelectric tube 14 tops sends is just covered once by shadow shield, through opto-electronic conversion, just once by instrument 22 records.
3. as previously mentioned, tested refractory brick sample 17 is under the promotion of sample hold down gag, the groove of being opened by the heating space sidewall closely contacts with emery wheel 10, under hot conditions, bear the grinding of certain intensity owing to the rotation of emery wheel, the degree of depth of its grinding is measured by degree of depth analyzer 20, after amplifying, the displacement trasducer rectifying and wave-filtering is input in the desk-top registering instrument 25, above said sample hold down gag, be meant the top thick stick 19 in the accompanying drawing 2 and pass through rope, the parts such as weight that fixed pulley etc. and top thick stick interrelate, because the action of gravity of weight, make top thick stick 19 realize sample advanced and compress by heat-insulating shield 13.
4. foregoing instrument measurement that links by sensor and each relative assembly and display system (seeing 5 in the accompanying drawing 1) except that the electro-optical system 13 and 14 of the mensuration grinding wheel speed of having said, measure and the instrument 20 and 25 of record wearing depth, write down the registering instrument 22 of emery wheel revolution in addition, wherein the record of temperature is also finished by 25 with demonstration in the heating space device.
5. the form of implementation of foregoing instrument support (seat) (seeing 4 in the accompanying drawing 1) comprises chassis 29 as shown in accompanying drawing 2, relevant column 21 grades are not stated self-evident interior by the signal of accompanying drawing 2.
The refractory brick high-temperature wearable analyzer that this design is finished can be used for measuring the high-temperature wearable and the normal temperature wearing quality of the refractory brick (as clay brick, high-alumina brick etc.) of dissimilar different components, thereby reach, in the serviceable life of refractory brick under high temperature, frayed situation of prediction different components, be beneficial to applying unit and select fire resistive material for use; With it is means, and research improves the production technology and the measure of refractory brick wearing quality; Study under the variant operating conditions influence, thereby improve the operating procedure of kiln the refractory brick wearing quality.
The utility model has the advantages that:
