Application

The detailed process of cold rolled stainless steel coil flattening.
The width of cold rolled coil is generally 1000mm, 1219mm, 1250mm, 1500mm, 1800mm, etc.

Cold rolled stainless steel coil Kaiping, the first leveling roll for rough leveling. The second leveling roller is used for precision leveling, and the deep well removes part of the stress of the stainless steel plate. After cutting out 3 pieces, it is re-scaled, and the quality is checked. After determining the quality indicators such as scratches, burrs, flatness, diagonals, length, etc., they will be transferred to automatic control. , During the continuous observation of the unit operation and the quality of opening.

The quality is then checked by a quality inspector; it is packed.

The heat treatment of cold rolled stainless steel coils a recrystallization heat treatment, which is carried out in a continuous furnace. Except for the temperature difference, there is not much difference between the 300 series stainless steel and the 400 series stainless steel, and both adopt the heating + heat preservation + rapid cooling production process.
(1) Oxidation annealing: carried out in the air medium, the surface of the strip has an oxide layer.
(2) Protection annealing: It is carried out in a protection gas (H2 or H2+N2 mixed), and there is no oxide layer on the surface.
