plastic metal workings; manufacture of composite materials, manufacture of steel-and-copper wire in particular. SUBSTANCE: proposed method consists in heating the blank followed by rolling and cooling in solution containing ethyl alcohol in the amount of 7 to 10%, water being the remainder or in solution containing aqua ammonia in the amount of 5 to 12%, water being the remainder or in solution containing aqua ammonia in the amount of 3 to 10%, ammonium chloride (2-10%), water being the remainder. Rate of motion of wire in cooling ranges from 4 to 6 m/min. Cooling solution is fed in circulating mode. EFFECT: possibility of hardening wire and cleaning its surface without additional special units. 3 cl, 1 tbl |
