METHOD FOR TREATMENT OF WIRE AND DEVICE FOR ITS REALIZATION Russian patent published in 1994 - IPC

FIELD: production of general metal goods, in steel-wire shops for production of patent wire. SUBSTANCE: wire is heated up to 820-970 C, held at this temperature, cooled intensive by blasting of gas with speed of gas flow 8-170 m/sec during 4-15 from 400 C up to 550 C, is cooled finally by water up to shop temperature. The surface of wire is cleaned of scale before intensive cooling. For that purpose holding is carried out in reduction atmosphere at 820-970 C. Device includes unroll device, furnace, thermostat, connected hermetically to the unit for stream cooling including camera provided with inlet and outlet openings located in cavity of this camera fan, whose outlet connection is coupled with refrigerator and pressure boxes provided with slotted nozzles mounted according to technological process and winding device. Slotted nozzles are equipped with V-shaped centered members. EFFECT: increased efficiency. 3 cl, 6 tbl
