Cold and hot rolling of stainless steel strip
Cold rolled:
① Using "stainless steel strip/coil" as raw material, it is rolled by cold rolling mill at room temperature. Conventional thickness <0.1mm~3mm>, width <100mm~2000mm>;
②["Cold-rolled steel strip/coil"] has the advantages of smooth surface, smooth surface, high dimensional accuracy and good mechanical properties, most of the products are in coils and can be processed into coated steel plates;
③The production process of cold-rolled stainless steel strip/coil: ⒈ Pickling → ⒉ Room temperature rolling → ⒊ Process lubrication → ⒋ Annealing → ⒌ Flattening → ⒍ Fine cutting → ⒎ Packing → ⒏ Reach customers.
Hot rolled:
①Strip steel with a thickness of 1.80mm-6.00mm and a width of 50mm-1200mm is formed by a hot rolling machine.
②[Hot-rolled strip/sheet] has the advantages of low hardness, easy processing, and good ductility.
③The production process of hot-rolled stainless steel strip/coil: ⒈ pickling → ⒉ high temperature rolling → ⒊ process lubrication → ⒋ annealing → ⒌ smoothing → ⒍ fine cutting → ⒎ packaging → ⒏ to reach the customer.
Difference between hot and cold:
①The strength and yield ratio of cold-rolled steel strip are good, and the ductility and toughness of hot-rolled steel strip are good.
②The thickness of cold-rolled steel strip is ultra-thin, and the thickness of hot-rolled steel strip is larger.
③The surface quality, appearance and dimensional accuracy of the cold-rolled steel strip are better than those of the hot-rolled sheet.

In which industries can precision stainless steel belts be used?
The energy spectrum analysis of ferrite and austenite components shortens the distance between stainless steel pipe manufacturers and users, and the chemical analysis results of electrolytic extraction of the ^ phase precipitated after isothermal aging at 800 degrees for different times. It can be seen that chromium and molybdenum are obviously enriched in the super phase of 316 stainless steel products, and the transformation ratio of molybdenum content in super phase is a function of time. When the molybdenum content increases, the chromium content decreases.

Wear resistance of stainless steel belts in the process
Based on the single-particle micro-cutting model of stainless steel strips, the evolution law and productivity control of the residual stress on the surface of HR-2 hydrogen-resistant stainless steel workpieces by the grinding process are studied and analyzed. Mathematical model of residual stress in single-particle micro-cutting of abrasive grains for stainless steel strips. Orthogonal experiments are used to obtain the grinding process parameters and surface residual stress, the depth of cut for abrasive grains and the regression equation of tangential force, and the single-factor experiment is used to verify the grinding process. , obtain the influence law of grinding process parameters on the surface residual stress, surface abrasive cutting depth and tangential force, and conduct a comparison study between the single-factor experimental results and the mathematical model calculation results.
