Hot-dip galvanizing process and equipment technology progress, the content mainly includes: automotive IF steel alloying galvanized sheet, high corrosion-resistant alloy coating, hot-dip galvanizing process containing silicon steel, the U.S. Steel Union hot-dip galvanizing production line, high-temperature annealing furnace, high corrosion-resistant and wear-resistant submerged rollers, air knives, high-frequency induction heating and alloying furnace and the internal heating of zinc pots and so on. In which hot dip galvanizing pot products are mainly used in the new development of galvanizing pot special steel plate, with its unique low carbon, low silicon, low sulfur and other aspects of the advantages of the formation of the company to provide the galvanizing industry special hot dip galvanizing pot.
Hot dip galvanizing pot The product has the performance, can effectively go to improve the resistance to zinc corrosion, prolong the service life of galvanizing pot, zinc consumption is small, inhibit the deformation, reduce the generation of zinc slag.
1、Furnace temperature is controlled under 750℃.
2. The temperature of zinc liquid is lower than 460℃ for galvanizing. Before the galvanizing pot heating start, should be drawn up in line with the actual situation of the heating curve, the temperature should be less than 10 ℃ per hour.
3, galvanizing pot use, the zinc slag at the bottom of the zinc solution should not be higher than 150mm, more than should be removed in a timely manner, the appearance of zinc dust should not be accumulated.
4, the pot should maintain a reasonable capacity of zinc liquid, zinc liquid surface can not be lower than the heating surface, to prevent the zinc liquid surface of the high temperature corrosion zone. Production needs to control a larger output, production and galvanizing pot volume ratio should be scientifically reasonable, its heat input and output to maintain a relative balance and stability.
5, galvanized pot in the heating planning and use of the heating surface must be uniform, not part of the high temperature.
