Characteristics and application of cold rolled steel strip

Steel strip, steel coils, hot rolled steel strip, cold rolled steel strip, hardened & tempered steel strip, 65Mn steel strip, CK50 steel strip, CK75 steel strip, rolling door springs, spring boxes

Cold rolled steel strip is rolled under recrystallisation, but is generally understood to be rolled using ambient rolled material. Aluminium cold rolled is divided into sheet and foil rolled. Those with a thickness of 0.15~ or more are called plates and those below 0.15~ are called foils. Europe and America mostly use 3~6 continuous mills as cold rolling facilities

Cold-rolled steel strip production is the finishing process of steel strip rolling. The raw material for cold rolled steel strip is hot rolled steel strip. To obtain a high quality cold rolled steel strip, a good raw material of hot rolled steel strip is necessary to ensure. The chemical composition of the steel, purity and control of the hot rolling process, the final cold rolled steel strip products have a great impact on the organization, performance; hot rolled steel strip size, plate shape and surface state, will directly affect the size accuracy of cold rolled steel strip, plate shape and surface quality.
Steelmaking control of the chemical composition of steel is to ensure the production of high-quality cold-rolled steel strip, the chemical composition of steel and steel strip forming properties have a close relationship. Steel carbon content on the steel strip forming properties of the impact is through the impact of the yield limit and plastic strain ratio of steel to achieve. Carbon is one of the most significant elements to improve the strength of steel, carbon content increases, the yield limit increases, the plastic strain ratio decreases, the forming properties become worse.

Cold rolled steel has good performance, that is, through cold rolling, you can get a thinner thickness, higher precision cold rolled strip and steel plate, high straightness, high surface finish, cold rolled plate surface clean and bright, easy to carry out coating processing, variety, wide range of uses, while having high stamping performance and not aging, low yield point characteristics, so cold rolled plate with a wide range of uses, mainly used in automotive, printing barrels, construction, building materials It is also the best material for the production of organic coated steel sheets.
