Description

Metal plate belt surface brushing experiment system

Technical Field

The utility model relates to the field of surface cleaning experiments of cold metal plate strips, in particular to a surface brushing experiment system of a metal plate strip.

Background

The metal material forms a layer of dense covering composed of metal oxide on the surface during hot rolling or heat treatment, and is commonly called as scale skin due to uniform cracking after bending. The presence of scale can have a direct impact on further processing. Therefore, the scale must be removed from the surface of the steel sheet before it is subjected to various post-treatment processes such as cold rolling, plating, and stamping. The descaling procedure becomes one of the necessary processes on the metallurgical production line. In order to realize effective descaling, enterprises at home and abroad adopt a chemical wet method for soaking and dissolving modes for many years, so as to thoroughly remove surface scales. For steel sheet rolls, various strongly acidic solutions or mixed solutions of sulfuric acid, hydrochloric acid, hydrofluoric acid, etc. are generally used. The pickling and acid regeneration processes generate a large amount of waste gas and dust, and HCL, SO2 and the like which are always contained in the waste gas and dust directly pollute the atmosphere. Therefore, in order to solve the pollution caused by chemical acid washing, scientific researchers have made a great deal of researches and developed various technologies and devices to replace the chemical method for removing the scale on the metal surface, such as withdrawal and straightening, scale breaking, shot blasting, laser, jet flow and the combination of the different methods.

Meanwhile, the surface cleanliness of the metal plate strip in the production and manufacturing process is one of key factors affecting the product grade and the yield of finished products. The surface of the metal plate strip after cold-state casting is inevitably adhered with a layer of rolling oil because of the process of lubrication and cooling, and the rolling oil also contains a large amount of water, iron powder and the like. In order to ensure the quality of the subsequent annealing, coating and plating processes, the process of cleaning the annealing, coating and plating processes on line is required, and the cleaning process is called degreasing. Degreasing does not reach the standard, so that the decarburization effect of the annealing process is weakened, the furnace atmosphere is polluted, even a carburetion phenomenon is caused, the furnace roller is nodulated, and finally the surface quality of the strip steel is reduced and the strip steel is scratched. Therefore, the cold-rolled metal sheet is usually subjected to a combined mode of alkali liquor soaking and cleaning, electrolytic alkali liquor cleaning and clear water rinsing, and the combined cleaning process of alkali liquor soaking, electrolysis and the like has the advantages of high cleaning speed and good oil removal effect. However, the cleaning process also has the typical problems of high energy consumption, high alkali liquor consumption, high hazardous waste and the like. Especially, the waste lye generated after the consumption of lye has large treatment difficulty and strict control.

Based on the two targets, it is necessary to design a comprehensive experiment platform capable of simultaneously taking scale removal and degreasing into consideration. For this reason, looking at the past published literature data found:

chinese CN201220619113 discloses an abrasive belt grinding experiment platform, and CN201220619235 discloses an abrasive cloth experiment platform, however, these two experiment platforms are only used for continuously grinding annular closed abrasive belt and circular abrasive cloth, and cannot give consideration to the ability of flushing and brushing;

chinese CN200267765 discloses an experimental platform for comprehensive detection of tightness of a shield tail brush of a shield machine, the platform mechanism is limited to a certain sector arc surface of the shield tail brush, and the object is concrete sand stone or the like, so that the required functions of the present utility model cannot be simulated;

chinese CN201621213674 discloses wear resistance, fatigue toughness, etc. of a brush wire, however, the platform only detects a single brush wire, and cannot simulate the required functions of the present utility model.

In order to more clearly understand the technical scheme, the hot rolled steel plate is used for brushing and descaling experiments, and the method specifically comprises the following steps:

as a test specimen, a Q235 hot-rolled steel sheet having a thickness of 6mm by 150 mm by 400mm was used. The experimenter opens the material access window 61 of unit shell 6 one end, with experimental template clamping on panel fixing device 2's upper end plane. Then the material inlet and outlet window 61 is closed, the pump set 74 and the second motor 32 are sequentially started to realize normal jet output of the plurality of first nozzles 41 of the first jet flushing mechanism 4 (the jet output pressure can reach 0.5 Mpa), meanwhile, the inlet liquid pressure of the brushing nozzle 34 is 0.3Mpa, the rotating speed of the rolling brush 33 is set to 900rpm, and the vertical rolling reduction of the rolling brush 33 relative to the sample plate is set to 2mm.

At this time, the experimenter starts the whole experiment through operating the host computer, and the panel fixing device 2 drives driving roller 12 rotatory under the effect of first motor and belt, and then under the combined action of four driving rollers 12, drives and carries track 11 annular to move to drive panel fixing device 2 and accelerate from the one end (initial station) of transfer chain 1 to the other end and remove, acceleration is not less than 5m/s2, ensures that panel fixing device 2 horizontal acceleration can reach the horizontal velocity 50m/min of settlement before the region that second efflux washing mechanism 4 is located.

At this time, the second jet flushing mechanism 5 is opened for spraying, the first jet flushing mechanism 5 is closed, the second nozzle 51 is kept continuously sprayed at a pressure of 0.5Mpa, the brushing nozzle 34 is continuously opened at a pressure of 0.3Mpa (i.e., 3 bar), and continuous spray cooling of the plate surface and the brushing surface is realized. And the rotational speed of the roll brush 33 was maintained at the set rotational speed of 900rpm and the reduction of 2mm. The sheet fixing apparatus 2 in this state was passed through the roll brush 33 at a speed level of 50mpm, i.e., the brushing grinding of the first pass was completed.

After the plate fixing device 2 and the sample plate pass through the instant flushing mechanism 5 in sequence, the brake is immediately started from a uniform speed state to a position 1m away from the end part of the other end of the conveying line 1.

Then, before the first motor drives the conveying crawler belt 11 to reversely run so that the plate fixing device 2 and the sample plate reversely accelerate from the brake stop position at the other end of the conveying line 1 to the second jet flushing mechanism 5, the plate fixing device 2 reaches 50 mpm; and at this time, the second jet flushing mechanism 5 stops spraying water, the rolling brush 33 reaches a rotation speed of 900rpm, the brushing nozzle 34 maintains the pressure injection of 0.3Mpa, and the first nozzle 41 maintains the pressure injection of 0.5 Mpa; in this way, the plate fixing device 2 and the template sequentially pass through the reverse grinding of the rolling brush 33 and the low-pressure flushing of the first nozzle 41, then enter the braking deceleration stage again, and the speed is zero until reaching the initial station near one end of the conveying line 1, and remain stationary.

At this time, the template surface on the plate fixing device 2 has completed two passes of forward and reverse brushing grinding. The experimenter can take out the template from the plate fixing device 2 for subsequent detection and analysis; meanwhile, an experimenter analyzes and sorts various data acquired from the host computer to obtain signal parameters such as electricity, mechanics and the like required by the experiment.

The embodiment can also be used for verifying a hot alkali liquor high-pressure flushing experiment, and is specifically as follows:

and opening a material inlet and outlet window 61 at one end of the unit shell 6, and clamping the sample plate on the upper end plane of the plate fixing device 2. Meanwhile, the temperature of the liquid in the water supply tank 73 (detected by an electronic thermometer) is set to 80 ℃ in the setting on the host computer, and the heater 75 is turned on to keep the alkali liquid in the water supply tank 73 after reaching 80+/-5 ℃. Then the experimenter closes the material inlet and outlet window 61, and sequentially starts the pump set 74 and the second motor 32, so that the first nozzle 41 and the second nozzle 51 have injection water sources, the injection pressure is set to 10Mpa (i.e. 100 bar), and the rolling brush 33 reaches the set rotation speed of 750rpm required by the experiment.

At this time, an experimenter starts the whole experiment through the host, and the movable plate fixing device 2 is driven by the conveying crawler 11 to run from one end to the other end in an accelerating manner (the specific process refers to the experimental process).

In this way, the horizontal velocity of the sheet material holding device 2 has reached 50mpm before the sheet material holding device 2 has accelerated to the position of the first jet flushing mechanism 4. And at this time, the first nozzle 41 is disconnected from the supply of the cleaning liquid, and the second nozzle 51 is normally supplied, and sprayed at a high pressure, for example, a spray pressure of 10Mpa (i.e., 100 bar); the brushing nozzles 34 maintain a normal liquid supply and brushing cooling is effected by spraying at a low pressure, i.e. with a pressure set at 0.3Mpa (i.e. 3 bar). But the rotating speed of the rolling brush 33 reaches the set rotating speed (such as 900 rpm) and the rolling reduction reaches the standard; the plate fixing device 2 passes through the rolling brush 33 according to the set horizontal speed, after the first pass brushing is finished, the plate fixing device 2 and the sample plate sequentially pass through the lower part of the second jet flushing mechanism 5 and are flushed by the alkali liquor with the temperature of 10Mpa multiplied by 80 ℃ instantly, and then enter a brake deceleration stage from a uniform speed state to a brake stop position close to the other end of the conveying line 1.

Then, the conveying line 1 runs reversely to drive the plate fixing device 2 and the sample plate to accelerate reversely from the other end of the conveying line 1 to one end (initial position), and the plate fixing device 2 reaches 50mpm before reaching the second jet flushing mechanism 5; and the second nozzle 51 stops spraying water, the rolling brush 33 reaches the rated rotation speed. The scrubbing nozzle 34 still sprays 80 ℃ alkali liquor at 0.3Mpa pressure, while the first nozzle 41 keeps spraying at 10 Mpa; thus, the plate fixing device 2 and the sample plate sequentially pass through the reverse grinding of the rolling brush 33, and after the alkali liquor of 10mpa×80 ℃ of the first nozzle 41 is washed, the plate enters the brake deceleration stage again, and the speed is zero until the plate reaches the initial station near one end of the conveying line 1, and the plate is kept still.

At this time, the surface of the template on the plate fixing device 2 is washed by the alkali liquor in the forward direction and the backward direction and the high-pressure hot alkali liquor in two passes. The experimenter can take out the template from the plate fixing device 2, and detect and analyze the residual grease on the surface of the template; meanwhile, the experimenter records data of various electrical elements (such as a thermometer, operation parameters of various motors and the like) on the host machine, analyzes and sorts the data to obtain signal parameters such as electricity, mechanics and the like required by the experiment, and further enriches experimental result data.
