Cold rolled strip
① “Stainless steel strip / coil” is used as raw material and rolled into cold rolled mill at normal temperature. Conventional thickness <0.1mm ～ 3mm>, width <100mm ～ 2000mm>;
② ["cold rolled steel strip / coil"] has the advantages of smooth and smooth surface, high dimensional accuracy and good mechanical properties. Most of the products are rolled and can be processed into coated steel plates;
③ Cold rolled stainless steel strip / coil production process:
⒈ pickling → ⒉ normal temperature rolling → ⒊ process lubrication → ⒋ annealing → ⒌ flattening → ⒍ fine cutting → ⒎ packaging → ⒏ reach the customer.
Hot rolled strip
① The hot-rolled mill is used to make strip steel with a thickness of 1.80mm-6.00mm and a width of 50mm-1200mm.
② [Hot-rolled strip / sheet] It has the advantages of low hardness, easy processing and good ductility.
③ Production process of hot rolled stainless steel strip / coil:
⒈ pickling → ⒉ high temperature rolling → ⒊ process lubrication → ⒋ annealing → ⒋ smoothing ⒍ ⒍ fine cutting → ⒎ packaging → ⒏ reach the customer.
Hot and cold difference
① Cold rolled steel strip has good strength and yield ratio, and hot rolled steel strip has good ductility and toughness.
② The surface quality, appearance and dimensional accuracy of cold-rolled steel strip are better than those of hot-rolled steel.
③ The thickness of cold-rolled steel strip is ultra-thin, and the thickness of hot-rolled steel is large.
