The development of hot-dip galvanized pot and its advantages

The process of forming a layer of metal zinc on the surface when the surface metal material or part is immersed in the molten zinc liquid, and the physical and chemical reaction occurs with the outside air or other substances, and the process is mainly used for metal facilities in various industries. Hot dip galvanized pot is the key equipment of hot dip galvanized steel strip, zinc pot work for a long time in the condition of high temperature oxidation and attachment, so the material is not important, after years of experimental research has achieved the transformation from complex to simple.

As early as the zinc pot is made of pig iron, this pot contains high carbon and silicon content, poor corrosion resistance, short service life. Later, it was developed to have steel plate production, using pure iron steel plate, but the strength of China is low, easy to deform at high temperatures and the service life is short. Under normal use, the service life of POTS made of low carbon and low silicon steel plates can be improved to one and a half to two years, which is still too low for steel belts. After many tests and experience that the heat supply of zinc pot is 8360kj/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, the development of power frequency induction heating refractory ceramic pot.

Previously used iron zinc pot has experienced from the beginning of coal, oil, gas to the current resistance heating, from the equipment simple investment is small, low thermal efficiency, low temperature control accuracy, large labor force, to the current investment, high heating, good operating environment, simple, uniform heating, high temperature control accuracy, easy maintenance and other processes.
