CATHODE COPPER FOR MANUFACTURE OF COPPER ROLLED PRODUCTS AND METHOD FOR CONTROLLING QUALITY OF ROLLED PRODUCT Russian patent published in 2000 - IPC

FIELD: nonferrous metallurgy, in particular, manufacture of copper rolled products in continuous casting and rolling units. SUBSTANCE: rolled product is manufactured by remelting, casting and hot rolling of cast billet from cathode copper comprising crystals with texture axis of <111> relative to direction of deposit growth, and crystals of other textures with dense package of surfaces with copper atoms, at minimum content of crystals with texture axis of <110>. Cathode copper quality method involves performing crystal analysis by diffraction and/or metallographic methods; registering number of crystals of mentioned textures; regarding cathode copper, containing prevailing quantity of crystals with texture axis of <111> relative to direction of deposit growth, and crystals of other textures with dense package of surface with copper atoms at minimum content of crystals with texture axis of <110>, as cathode copper with good rollability. EFFECT: increased efficiency, improved quality of copper rolled products and effective controlling of quality of rolled product. 3 cl, 1 tbl, 1 ex
