摘要： A method for combined rolling and extruding of cast billet is proposed. When implementing the method for combined rolling and extruding of metals or alloys, a cast billet with a predetermined temperature is fed to the working gauge, in which it is rolled and then to the die, through which the cast billet is extruded. When the cast billet is fed into the working gauge, a cladding layer of metal or alloy is created on the surfaces of the rolls by extruding the cast billet through the gaps formed between the surfaces of the rolls and the die. This invention makes it possible to improve the quality of the resulting products, as well as to increase the efficiency of the process as a whole.
