FIELD: plastic working of metals, possibly making blanks of working walls of molds of billet continuous casting machines.
SUBSTANCE: method comprises steps of forming piece blank of oxygen free copper by cutting it off with use of belt saw from ingot produced in furnace for electron-beam refining; milling blank along contour and chamfering it; then performing its deformation strengthening by forging at deformation degree 20-30% and temperature 20°C.
EFFECT: improved operational strength of working walls of mold.
