Development and advantages of zinc boilers

Published: 2018-05-30 Author: Click:

Zinc boilers immerse metal materials or parts on the surface in molten zinc, and react with air or other materials to form a layer of metal zinc on the surface, mainly used in various industries on metal facilities. Hot-dip galvanizing pot is the key equipment for hot-dip galvanizing of steel strip. The material is unimportant because of the high temperature oxidation and attached condition for a long time. After years of experimental research, it has realized the transformation from complex to simple.

Zinc boiler


The earliest zinc pots were made of pig iron, which had high carbon and silicon content, poor corrosion resistance and short service life. Later, steel plates were developed, using pure iron plates, but the strength of China is low, easy to deform at high temperatures and short service life. The service life of the pot made of low carbon and low silicon steel sheet can be increased to one and a half to two years under normal use, which is still too low for the steel belt. After many tests and experience, it is known that the maximum heating capacity of the zinc pot is 8360 kJ / h, but such a large area of heat transfer surface is impossible to achieve, so the iron-zinc pot is impossible to meet. In this case, a power frequency induction heating ceramic pot has been developed.

The iron-zinc pot used in the past has experienced from coal-fired, oil-fired, gas-fired to resistance-heated, from simple equipment investment is small, thermal efficiency is low, temperature control accuracy is low, labor force is large, to the present investment is large, heating is high, operating environment is good, simple, uniform heating, temperature control precision is high, convenient maintenance and so on. Process.
