Abstract

FIELD: metallurgy. SUBSTANCE: method involves heating wire to temperature exceeding; holding at this temperature; intensively cooling to temperature of M(h) and providing ultimate cooling. Intensive cooling process is conducted by blowing gas at cooling rate ranging between 30 and 1,000 C per sec for time period of τ, determined by dependence recited in Specification. Apparatus has heater, pressure chamber with nozzle, cooling medium source and wire winding mechanism. Slit nozzle is extending along axis of apparatus, which may be further provided with cooling chamber, thermal holding chamber and reduction holding chamber. EFFECT: increased efficiency, provision for ecologically clean process by thermal treatment without usage of plumbum, potassium nitrate and acid and reduced production costs. 22 cl, 15 dwg, 7 tbl

, выдержки при этой температуре, интенсивное охлаждение до температуры выше Мн и окончательное охлаждение. Новым является то, что интенсивное охлаждение ведут продувкой газом со скоростью 30 - 1000oС в с времени τ, определяемого из зависимости: τ = (0,8-4,5)•d•vг•10-2, где d - диаметр проволоки, мм; Vг - скорость газового потока, м/с, при этом после интенсивного охлаждения до 500 - 620oС производят выдержку при этой температуре. Устройство содержит нагреватель, напорную камеру с соплом, источник охлаждающей среды и сматывающий механизм, при этом сопло выполнено в виде продольной щели размещенной вдоль оси технологического процесса. Устройство может быть снабжено камерой охлаждения, камерой термической выдержки, камерой восстановительной выдержки.The invention relates to the metallurgy of steel. Purpose: to develop a method and device for heat treatment of wire, allowing this processing to be carried out on an environmentally friendly basis, without the use of lead, nitrate and acid, resulting in increased efficiency of the process. The method includes heating to a temperature above
Figure 00000001
, holding at this temperature, intensive cooling to a temperature above Mn and final cooling. New is that intensive cooling is carried out by gas purging at a speed of 30 - 1000 o С with time τ, determined from the dependence: τ = (0.8-4.5) • d • v g • 10 -2 , where d - wire diameter, mm; V g - the speed of the gas stream, m / s, while after intensive cooling to 500 - 620 o With produce exposure at this temperature. The device comprises a heater, a pressure chamber with a nozzle, a source of cooling medium and a winding mechanism, while the nozzle is made in the form of a longitudinal slit placed along the axis of the process. The device may be equipped with a cooling chamber, a thermal exposure chamber, a recovery exposure chamber.
