Brief Introduction of Galvanizing Line

Galvanizing line in JIGANG group Cold Rolling Plant is a domestic line,Which is designed by Beijing Iron&Steel Research Institute and manufactured in local workshop.The total investment of the project is up to 180 million RMB and the field area 120mu(80,000m²).The galvanizing line was started to construct in March,2003,and put into production on May 24 ^th ,2004.

The UEC process applied in our galvanizing line is techni-cally supervised by Beijing Iron&Steel Research Institute. The main equipments in the line,such as welder and air-knife are supplied by VAI,Others are manufactured in local workshop.The galvanizing line is comprised of pay-off reel,pinch leveler,cross shear,C-flat narrow lap seam welder,electrolyze degrease cleaning device,deoxidize annealing furnace,zinc pot,air-knife,skin pass mill,tension leveler,passivation device,electrostatic oiler, coiler,etc.

The design capacity is 200,000 tons/a.The main product specification is 0.2--1.2mm thick and 800--1250mm wide.The line can produce hot-galvanizing strip steel with 60--275g/m² normal zinc spangle,small spangle and polishing spangle.The coil inner diameter is 508mm.Weight is 5--15 tons.The prod-ucts are mainly used in the architectural industry and light industry.
