DX51D Z100 GI coil Z40 GI sheet zinc galvanized Steel Coil hot dip galvanized steel sheet
The process flow of galvanized sheet is as follows:
1. Firstly, the cold-rolled steel plate is degreased by alkali washing and water washing, and then it is annealed in the horizontal (vertical) heating furnace with radiant tube heating after drying, and a certain amount of hydrogen is introduced into the furnace to create a reduction atmosphere in the furnace.
2. The steel strip heated to a certain temperature is immersed in zinc solution for hot galvanizing under certain conditions.
3. To control the size of the flower zinc, use the small liquid zinc method to control the diffusion of zinc in the product.
4. After hot-dip galvanizing and cooling, the surface is smoothed, and the surface is passivated or directly produced into color coated coil plate according to the use.
Advantages of galvanized sheet: 1. Low processing cost 2. Durable 3. Good reliability 4. Toughness of coating 5. Comprehensive protection 6. Saving time and labor 8. Simple and convenient inspection
