在工业条件下可以使各种轧件[1—4],管[5,6],建筑型钢[7,8]进行高温形变热处理(BTMO)。弹簧钢丝以前仅能在实验室条件下进行高温形变热处理。在高速拉丝和加热温度达到900～1000℃时出现了相当大的困难;经常断丝、工具寿命降低,润滑和冷却不可靠等等。本文作者们研究了50CrVA弹簧钢丝高温形变热处理过程,这个过程是在合金钢丝车间进行的。高温形变热处理拉丝工业性实验设备由现代化的1/350拉丝机(1),加热感应器(3),
Under industrial conditions, all kinds of rolling materials [1-4], pipes [5,6], building steel [7,8] can be subjected to high temperature heat treatment (BTMO). Spring wire was previously only subjected to high temperature heat treatment in laboratory conditions. There is considerable difficulty in high speed drawing and heating temperatures up to 900-1000 ° C; frequent filament breaks, reduced tool life, unreliable lubrication and cooling, and the like. The authors studied the high temperature deformation heat treatment of 50CrVA spring wire, which is carried out in alloy steel wire workshop. High-temperature thermomechanical drawing brushed industrial experimental equipment from the modern 1/350 drawing machine (1), heating sensors (3),
