Abstract
The utility model discloses an energy-saving device of a galvanized zinc pot. The device comprises a pot body and a grate leading a steel strip into the pot body, wherein the pot body is provided with a pot opening; and a ceramic fiber pot lid for sealing the pot opening is arranged at the pot opening in the rear of the grate. According to the energy-saving device of the galvanized zinc pot, by virtue of the ceramic fiber pot lid at the pot opening of the zinc pot, the zinc pot surface area is reduced, that is, the radiating area of the zinc pot to the air is reduced; with the reduction of the radiating area, the electricity consumption power of the zinc pot is reduced; and after the surface temperature of a zinc liquid is guaranteed, the surface temperature and temperature of the zinc liquid in a core part can be kept consistent basically, and temperature gradient from the surface to the core part of the zinc liquid is reduced. A ceramic fiber material has the characteristics of high-temperature resistance, corrosion resistance and low heat conduction coefficient, so that with the adoption of the ceramic fiber pot lid, the service life of the pot lid is effectively prolonged while the heat in the zinc pot is effectively prevented from being radiated and the temperature of the zinc pot is kept; and the liquid level can be stabilized, liquid level fluctuation of the zinc pot is reduced, and uniformity of a strip steel zinc layer and surface quality of a galvanized plate are improved.
Description
Technical field
The utility model relates to a kind of galvanizing technique, especially a kind of energy saver of zinc-plated zinc pot.
Background technology
Along with pot galvanize product is day by day in the widespread use of building, light industry, household electrical appliances and automobile industry, the general commercial plates such as civilian, building, require the supply of material of larger-size zinc flower; Usually use as coloured coating plate substrate without zinc flower and small zinc flower, or after polishing as the various containers, household electrical appliances, electric installation shell etc. that need further japanning, people are more and more stricter to heat zinc coating plate surface and the requirement of even zinc layer degree.
Hot galvanizing apparatus is generally three roller six arm one stove nose structures, is made up of zinc pot, stove nose, sinking roller, front stabilizing roller, rear stabilizing roller and air knife and setting device thereof; Its working process is: the zinc liquid that steel band enters in zinc pot through stove nose carries out immersion plating, goes out zinc pot after walking around sinking roller, then by forward and backward stabilizing roller and air knife, enters alloying furnace or cooling stages.Along with the increase of zinc-plated manufacturer, market competition is fierce all the more, and zinc-plated production cost control more and more demonstrates its critical positions.Under the prerequisite of same quality product, low cost production becomes the prerequisite of iron and steel enterprise's existence, and in zinc-plated production, power consumption mainly comes from zinc pot insulating sections.At present, still do not have zinc-plated factory to control effectively to power consumption.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of energy saver that not only can guarantee to reduce zinc pot power consumption but also can guarantee the conforming zinc-plated zinc pot of zinc liquid temperature; The utility model also provides a kind of power-economizing method of zinc-plated zinc pot.
For solving the problems of the technologies described above, the technical scheme that the utility model device is taked is: it includes a pot body, steel band is introduced to the stove nose in pot body, and described pot body is provided with pot mouthful, is provided with the ceramic fiber pot cover of capping pot mouth on the pot mouth at stove nose rear portion.
Pot cover described in the utility model is the ceramic fiber pot cover of thickness 45～55mm.
The beneficial effect that adopts technique scheme to produce is:
1) by the ceramic fiber pot cover of zinc pot pot mouth, reduce zinc pot surface-area, reduce zinc pot to the area dispelling the heat in air;
2) by the reduction of area of dissipation, and then reduce zinc pot power consumption;
3) after zinc liquid surface temperature is protected, surface temperature can maintain basically identical temperature levels with core zinc liquid, and reduction zinc liquid is the thermograde to core by surface.
4) ceramic fiber material has high temperature resistant, corrosion-resistantly, and the feature that thermal conductivity is low, therefore, adopts ceramic fiber pot cover, can be effectively stoping dissipation of heat in zinc pot, and when keeping zinc pot temperature, the work-ing life of effectively improving pot cover.Cover the thick ceramic fiber pot cover of 45～55mm, can stablize liquid level, reduce zinc pot liquid fluctuating, improve band steel even zinc layer and galvanized sheet surface quality.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Embodiment
Shown in Fig. 1, hot galvanizing apparatus is generally three roller six arm one stove nose structures, formed by zinc pot 4, stove nose 2, sinking roller, front stabilizing roller, rear stabilizing roller and air knife and setting device thereof, its working process is: the zinc liquid that steel band 1 enters in zinc pot through stove nose 2 carries out immersion plating, after walking around sinking roller, go out zinc pot, by forward and backward stabilizing roller and air knife, enter alloying furnace or cooling stages again.The energy saver of this zinc-plated zinc pot is the pot mouthful at zinc pot pot body 4 latter halfs, i.e. the pot at stove nose rear portion mouthful upper (without sinking roller and the position that does not need to add zinc ingot metal) capping has the ceramic fiber pot cover 3 that 45～55mm is thick; Ceramic fiber pot cover 3 can be movable cover on pot mouth, also can be fixed on pot mouthful.Ceramic fiber pot cover 3 plays heat-blocking action, and co-content zinc pot can not cover according to practical situation, and the larger effect of coverage rate is better.When the zinc-plated zinc pot that employing is provided with above-mentioned energy saver is produced, zinc pot temperature, than not adopting the production temperature before energy saver to reduce by 10 ℃, can normally be produced.
Take Hebei cold rolling mill 3# galvanizing line as example, can the pot mouth at the stove nose rear portion of zinc pot be covered completely with ceramic fiber pot cover in process of production, only reserve zinc pot first half for three roller six arms in producing and to cross band steel used.This galvanizing line zinc liquid temp is controlled at zinc-plated best results within the scope of 450～455 ℃, zinc liquid surface increases after ceramic fiber layer, in zinc pot, zinc liquid diminishes to the area of distribute heat in air, zinc pot temperature can directly be reduced to 455 ℃ from 465 ℃, can stablize liquid level simultaneously, reduce zinc pot liquid fluctuating, improve band steel even zinc layer and galvanized sheet surface quality.According to record of production, in the time producing Z120 zinc layer, zinc pot power all maintains under low power state and moves, approximately 35～50Kw.And in former production process, every order of classes or grades at school all will have 0.5～1 hours internal power need to maintain 350～450Kw.Can obviously find out by contrast, after increase pottery ceramic fiber pot cover, power consumption reduces.Cover the thick high temperature resistant and corrosion resistant ceramic fiber pot cover of 45～55mm and can stablize liquid level, reduce zinc pot liquid fluctuating, originally due to air knife flow perturbation, zinc pot zinc liquid liquid fluctuating is at 15～20mm, in the rear zinc pot of covering, zinc liquid liquid fluctuating is in 10mm, stablize air knife scraping zinc liquid, guaranteed strip steel Zn-plating processing parameter consistence, improved band steel even zinc layer and galvanized sheet surface quality.
