Abstract
A heater coated with adhesive non-crystal glass glaze is composed of steel tube, electric heating element in said steel tube, fixers welded to steel tube for said electric heating element, filling between steel tube and electric heating element, and adhesive glaze resisting the corrosion of molten zinc, which is applied on external surface of steel tube. Its advantages are simple structure, high heat conductivity, and low cost.
Description
Technical field: what the present invention relates to is a kind of heater, and particularly a kind of heater coated with non-crystal viscose glass enamel belongs to casting field.
Background technology: zinc liquid has strong corrosivity to metal, exist improper zinc consumption high in the present industrial galvanizing, account for 40%～50% of the total consumption of zinc, the traditional zinc pot mode of heating of China has external-heat (be included in the bottom of a pan, pot side, pot before, pot back heating), goes up hot type (comprising one-sided, centre and bilateral radiation heating), the former conducts heat slowly, temperature is uneven, fuel factor is poor, and zinc pot local corrosion, many, the zinc consumption height of cadmia, particularly the bottom of a pan heating can make the boiling of zinc liquid, cadmia (mixing) roll, and directly influences product quality; The latter consume energy height, the thermal efficiency is low, the zinc gray growing amount is many, the zinc liquid temperature difference is big.Begin to develop internal heater in recent years, and internal heater was directly immersed zinc liquid inside heat, used Si

4Pottery preparation tubulose internal heater, this ceramic heat transfer efficiency is low, the easy more high shortcoming of crisp, cost.Also there are shortcomings such as fragility is big, cost is high, service life is short in SiC and quartz glass tube internal heater.Find by retrieval, people such as Cao Xiaoming write articles " rare earth element is to the modifying function of pack boriding layer " in the 15th the 4th phase of volume of " Chinese rare-earth journal " December in 1997, this article proposes the boronising metal steel pipe internal heater of development recently can not resist liquid zinc corrosion well, for plasma spraying metal steel pipe internal heater, because coating and expansion of metal coefficient are unworthy of causing coating to be broken, thereby can not resist the corrosion of zinc melt, in addition, the glaze of normal silicate glass and no boron high-content phosphorus can not be resisted the corrosion that zinc melts body.
Summary of the invention: the present invention is directed to the deficiencies in the prior art and defective, provide a kind of viscosity amorphous glass glaze is coated in heater on the metal steel pipe internal heater outer surface, the present invention mainly comprises: electrical heating elements, the electrical heating elements fixed mount, the viscous coating glaze of anti-zinc melt corrosion, the metal steel pipe, filler, concrete connected mode is: electrical heating elements is put into the metal steel pipe, electrical heating elements and fixed mount are welded on an end of metal steel pipe, filler is put into the space between metal steel pipe and the heating element heater, and the viscous coating glaze of anti-zinc melt corrosion is coated in the metallic steel tube outer surface.Metal steel pipe one end opening, end sealing, openend and the welding of electrical heating elements fixed mount.
Operation principle of the present invention is as follows: electrical heating elements is put into the metal steel pipe, then filler is put between metal steel pipe and the heating element heater, then electrical heating elements and fixed mount are welded on metallic steel tube opening one end, at last the metallic steel tube outer surface are carried out glazing.The zinc pot cover socket of this coating metal steel pipe internal heater that has viscosity and can resist zinc melt corrosion from melting industrial-purity zinc directly inserted, connect the power supply of heating element heater subsequently, then internal heater begins the melting industrial-purity zinc that generates heat.
Use can be resisted the high-load B of zinc melt corrosion

5Amorphous glass glaze coating material utilizes the metal steel pipe as the backing material that melts the zinc internal heater, can increase internal heater heat transfer efficiency, heat shock resistance and mechanical shock ability like this.The stickum (amorphous glass glaze) of anti-zinc melt corrosion is coated in metal steel pipe internal heater outside, when contacting with the zinc melt, this stickum chemical reaction can not take place, in the temperature range of melting zinc, the amorphous glass glaze that is coated on the metallic steel tube outer surface begins to soften and have viscous effect, therefore glaze can stick on the metal steel pipe well like this, uses the metal internal heater melting industrial-purity zinc well that scribbles this coating.
The present invention has substantive distinguishing features and marked improvement, and the present invention is simple in structure, easy to operate, heat transfer efficiency is high, cost is low, coating process is simple, uses this new coating internal heater can energy savings, improves heat and crosses the zinc quality.
