The zinc pot is one of indispensable key equipment with high value and easy consumption in the hot dip galvanizing production. Because the high value and easy consumption of zinc pot decreases the economic benefit of hot dip galvanizing factories considerably, how to find a new material to insulate molten zinc from the pot is very important for hot dip galvanizing factories and also a difficult problem to be solved necessarily for many engineering and technical personnel in hot dip galvanizing field. Through the common effort of many scientific and technical personnel, our company has developed “XG-T-2 protection coating for internal wall of zinc pot”. The protection coating can effectively prevent the corrosion of zinc pot by molten zinc and decrease energy and material consumption, and so it is well received by customers.
