After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, ZQS700L cold forming automobile structure steel tubes, wires, belts, and profiles have a certain scale, including magnetic, elastic, expanded, bimetal and other precision alloy materials for national defense and electronics industries. In 1982, these plants produced 364,000 tons of ZQS700L cold forming automobile structure steel steel and 542,000 tons of steel.

The hardness of the steel plate is very high, so special equipment is needed to complete the processing and cutting of these materials, ZQS700L cold forming automobile structure steel. In order to cut the plate into an ideal size, the steel plate cutting needs to use natural gas flame for preheating, which will generate a large amount of oxygen flow during the operation. These substances will oxidize the steel plate, and then form a cutting edge, then the cutting operation process is basically completed. In the actual processing work, there are many different classifications for steel plate cutting.
