AGGREGATE FOR ANNEALING HF CURRENTS CALIBRATED STEEL Russian patent published in 1995 - IPC

FIELD: thermal treatment. SUBSTANCE: aggregate for annealing of HF currents calibrated steel has unreeling drum, drawing mechanism with apparatus to vary diameters of subjected to thermal treatment steel, heating unit and thermal chamber with winding drums, heater s and device of control and adjustment of temperature. Thermal chamber is divided for along circumference located zones, corresponding to positions of winding, processing cooling, accelerated cooling and unloading. Apparatus for bundle formation is mounted inside thermal chamber on winding position. Winding drums, rotation drive of which has device of speed rotation synchronization during winding up and of steel feeding speed, are located on turning table under thermal chamber. EFFECT: aggregate increases quality of thermal treated steel and improve significantly terms of its operation. 4 cl, 4 dwg
