The zinc pot is indispensable key equipment with high value and easy consumption in the hot dip galvanizing production. The greater part of the previous traditional zinc pots are made of special steel products (05F, 08F, industrial pure iron, etc) by welding method or cast iron. With the rapid growth of the national economy, the zinc consumption for hot galvanizing production has increased from 15% of zinc output 10 years ago to more than 45% of that now. According to incomplete statistics, the all zinc pots at home is estimated as 5000-6000 pieces. 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 substitute for it 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 of our company during some years and on the basis of investing a lot of funds and repeating tests, Xinyue Company has developed the “industrial ceramic” zinc pot with external heating function and solved the difficult technical problem successfully. The “industrial ceramic” zinc pot can be heated with many heating modes: Regardless of coal, oil, gas and electric power, they can be used for heating and its brickwork is simple. The new ceramic pot not only prolongs the working life of it, but also decreases 30%-40% of zinc slag. The zinc consumption / tonne of product has decreased from 70-100 kg to 40-50 kg (dip galvanizing of cast iron). The “industrial ceramic” zinc pot in some galvanizing factories has got a very good economic benefits successfully and is well received by many customers. Because of large difficulty of technology and manufacture, at present only column shape ceramic pot with maximum size ofф800×1100 and 2.5 tonnes of molten zinc can be made.
