20-40mm hot rolled steel plate is generally considered, the middle thickness plate is generally 20 or more, and the steel plate below 100, and the width of the steel plate is basically less than 3300 mm.
Steel coils, open flat plates, medium and thick plates. What is the difference between these three types of plates? Is it rolling the plate to open the plate? It's a good level, right?
The rolled board, as the name suggests, is a rolled board, this will not be explained;
The open plate refers to the cutting (opening) of the roll through the machine, and the predecessor is the roll plate. However, there are two types of flat planes: one is ordinary plane and the other is factory plane. The difference in use lies in the internal tension (female force).
Medium thickness plate refers to a medium plate with a wide thickness range, which is divided into raw edges, two-cut edges, and four-cut edges. The width can reach 4 ~ 5M.
Now there are open plates that can eliminate internal stress to a great extent, which can basically replace intermediate plates, but the thickness range of open plates is not as large as that of medium thickness plates.
