发明名称 METHOD OF PRODUCTION OF HOT-ROLLED STEEL STRIP
摘要 methods of production of hot-rolled steel strips. SUBSTANCE: method of production of hot-rolled steel strip from continuous cast semiproduct is realized in, at least, two stages of deformation. Each stage consists of one or several stands of rolls in which semiproduct, at the first stage of deformation is rolled at semiproduct output speed after plant of continuous rolling. Semiproduct before the second stage of deformation is coiled into intermediate coil without cutting at output speed fro the first state of deformation in order to subject the intermediate coil to, as if, endless finish rolling and then, coiled into coils of required size. At the first stage of deformation, at least, 40 t of casting assortment produced by continuous casting it is coiled into intermediate coil and intermediate strip of this intermediate coil is subjected, as if, to endless finish rolling and only after the second stage of deformation, it is cut in compliance with desired weight of coils and coiled in form of ready strip. EFFECT: provided production of very thin strip at high speed of finish rolling. 5 cl
