Description

technical field [0001] The invention relates to an anti-corrosion rolling oil composition and its application. Background technique [0002] Stainless steel has high hardness and is a difficult-to-machine alloy, which will harden during the rolling process of stainless steel. Especially in the continuous cold rolling production process, due to its high production efficiency and large deformation, the strip hardening phenomenon is more obvious. During the rolling process of steel, each grain is elongated, flattened, broken, and fibrous along the rolling direction. When the degree of deformation is large, many very small fragments will appear inside the broken and elongated grain The block and severe lattice distortion greatly increase the deformation resistance of the crystal, which is an important factor leading to work hardening. The degreasing annealing process can make the strip have good mechanical properties and processing properties. [0003] In the degreasing annea...
