STRIP COLD ROLLING PROCESS Russian patent published in 2001 - IPC

Abstract RU 2164451 C2

FIELD: metallurgy, namely rolled stock production, possibly cold rolling of thin strips of isotropic electrical steel. SUBSTANCE: process comprises steps of multipass reduction of hot rolled strip between rolls at supplying technological lubricant; reducing strip in last pass at deformation degree 15-25% with relation of thickness of rolled strip to roll diameter equal to (0.8-1.3) ×10³. EFFECT: enhanced quality of rolled strips of isotropic electrical steel due to creation of mostly favorable crystallographic texture of metal. 5 exp, 1 tbl
