Description
Technical field
What the present invention relates to is the zinc pot inductor baking process on a kind of hot-dip aluminizing zincium steel plate production line, belongs to the production technique of hot-dip aluminizing zincium steel plate.
Background technology
The production line of hot-dip aluminizing zincium steel plate generally adopts following technical process: the one, and hot-rolled sheet is through joining the cold rolling rolling process of milling train group; The 2nd, cold-rolled steel sheet is through the matting of alkali cleaning, washing; The 3rd, cold-rolled steel sheet is through stove annealed annealing operation; The 4th, annealed sheet steel is through the hot-dip aluminizing zinc operation of zinc pot, and the 5th, hot-dip aluminizing zincium steel plate drawn, the curved stretch bending operation of rectifying, the 6th, hot-dip aluminizing zincium steel plate finally becomes the hot-dip aluminizing zincium steel plate finished product through passivation, inunction process; Wherein coating aluminium zinc adds the thermal recovery inductor provides heat.Described inductor comprises the shell that is formed by welded steel plate, and inwall is stained with one deck asbestos plate with water glass and builds one deck insulating brick again, carries out ramming with smashing material then; The mould of inductor channel is a steelwork, successfully in channel, takes out in order to finish at ramming, and mould is that segmentation constitutes; In the ramming process, want segmentation to put into inductor to mould, after last one deck ramming material tamping, should exceed about 12 millimeters of inductor block box hat, use again till the doctor blade, smash under the solid situation not damaging then, take out mould.Stop up end channel stomidium, just accomplished whole ramming process.The inductor ramming finishes, and 500 watts electric heating body is respectively put into a power and is at first seasoning seven days in air then in three channels, need dry for four weeks at least, and the zinc pot of just can packing into comes into operation.But above-mentioned technology can't guarantee to shorten storing time under the prerequisite in inductor cured effect and life-span; Technological deficiencies such as exist the inductor structural instability, work-ing life is short, and storing time is long, and energy consumption is many.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, and a kind of inductor Stability Analysis of Structures is provided, long service life, storing time is short, to reduce stop time, the zinc pot inductor baking process on the hot-dip aluminizing zincium steel plate production line that cuts down the consumption of energy.
The objective of the invention is to accomplish through following technical scheme, described zinc pot inductor baking process comprises following two procedures: the one, and the natural curing operation will be smash material and processed concrete fluid shape; The inductor inwall was stained with one deck asbestos plate, a good wooden model and copper sheathing with water glass after, the cast flow-like was smash material, within 24 hours of cast end; The surface covers with wet gunnysack or other materials similar; And diligent watering, guarantee that covering material is in dampness, after 24 hours; Natural curing 7 days, envrionment temperature >=15 ℃; The 2nd, the inductor roasting procedure, the natural curing of inductor refractory materials is toasted by following baking curve after finishing, and wooden model is burnt, and burns the wooden model process, naked light can not occur, should make its slowly charing; Room temperature to 110 ℃, 10 ℃/hour of heat-up rates, and insulation 48 hours in the time of 110 ℃; 111 ℃ to 200 ℃, 10 ℃/hour of heat-up rates, and in the time of 200 ℃, be incubated 48 hours; 201 ℃ to 350 ℃, 10 ℃/hour of heat-up rates, and in the time of 350 ℃, be incubated 72 hours; After 350 ℃ of insulations finish, slowly cool to below 100 ℃ with 20 ℃/hour, clean out the inner residue of channel, prepare butt joint; Inductor toasts according to following temperature with after body of heater docks: room temperature to 150 ℃, 30 ℃/hour of heat-up rates, and insulation 5 hours in the time of 150 ℃; 151 ℃ to 350 ℃, 30 ℃/hour of heat-up rates, and in the time of 350 ℃, be incubated 5 hours; 351 ℃ to 530 ℃, 50 ℃/hour of heat-up rates, and in the time of 530 ℃, be incubated 48 hours; After 530 ℃ of insulations finish, can in channel, irritate aluminium zinc liquid.
The present invention is placed with at least two thermopairs with the storing temperature in the monitoring stove in described channel when baking.
The present invention makes the mould of inductor channel into wooden model by punching block, and ramming finishes not to be needed to take out mould, damages when avoiding taking mould and smashes material; Therefore the present invention has improved the inductor baking process, can guarantee to shorten storing time under the prerequisite in inductor cured effect and life-span.
The present invention guarantees the inductor Stability Analysis of Structures through improving the moulding stock and ramming, baking process of hot-dip aluminizing zinc steel band zinc pot inductor, long service life, and storing time is short, and minimizing stop time, the effect that particularly during emergency maintenance, is risen is more obvious.
Embodiment
To combine specific embodiment that the present invention is done detailed introduction below: zinc aluminum pot inductor baking process of the present invention comprises following two procedures:
A. natural curing time: will smash material and process concrete fluid shape, the inductor inwall was stained with one deck asbestos plate, a good wooden model and copper sheathing with water glass after, the cast flow-like was smash material; Within 24 hours of cast end, the surface covers with wet gunnysack or other materials similar, and the duty watering; Guarantee that covering material is in dampness; After 24 hours, natural curing 7 days, envrionment temperature >=15 ℃.
B. the baking of inductor: the natural curing of inductor refractory materials is toasted by following baking curve after finishing, and wooden model is burnt, and burns the wooden model process, naked light can not occur, should make its slowly charing, and the naked light temperature is too high, is prone to make the refractory materials cracking.
C, inductor and after body of heater docks, by toasting like lower curve:
The present invention needs in channel, to put 2 thermocouple monitoring temperature when baking; Must carefully conscientiously arrive controlled temperature, cause cracking in order to avoid moisture evaporation is too fast.
