Molten channel type core induction boiler for aluminum plating production line

Abstract

The invention discloses a melting channel type cored induction pot used in an aluminum plating production line, which comprises a pot body and an induction heater. The pot body includes a pot shell, insulation board, insulation brick, conventional castable, high alumina brick and high alumina castable; several induction heaters are installed on the outside of the surrounding walls of the pot body; coils and melting pots are installed inside the induction heater. communicate. In the technical solution of the present invention, the alternating magnetic field is generated by the coil, and the molten metal in the melting channel is heated by induction, and the aluminum liquid in the melting channel generates electromotive force under the alternating magnetic field, flows in the melting channel, and is finally sprayed into the pot At the same time, the aluminum liquid in the pot enters the melting channel, thereby generating heat exchange, and finally makes the aluminum liquid in the pot reach the set temperature value. The insulation board, insulation bricks, conventional castables, high-alumina bricks and high-alumina castables of the pot body constitute the refractory structure of the pot body, which can protect the pot body from the erosion of molten aluminum during aluminum plating.

Description

technical field [0001] The invention belongs to the technical field of hot-dip plating, and relates to a plating pot, in particular to a melting channel type cored induction pot used in an aluminum plating production line. Background technique [0002] Aluminum-plated products are more and more widely used in various industries. Due to the superior corrosion resistance of aluminum-plated and aluminum-silicon-plated products in high-temperature environments, such products have achieved considerable development in the fields of home appliances and automobiles. Previously, aluminized products relied heavily on foreign imports. At present, domestic iron and steel enterprises independently invest in R&D and construction of aluminum plating production line equipment. The aluminum plating pot is the key equipment of the aluminum plating production line. [0003] Aluminum-plated and aluminized-silicon products and their manufacturing processes have the following technical perform...

AI Technical Summary

Problems solved by technology

Based on the above technical characteristics, the development of aluminum-coated aluminum pots mainly has the following technical difficulties: aluminum easily reacts with silicon in refractory materials at high temperatures to reduce the corrosion resistance of refractory materials; The slag will block the melting channel of the induction heater and reduce the service life of the induction heater; the liquid aluminum has strong penetrability at high temperature, and it is easy to leak and endanger human safety
