一温度是热处理工艺中最重要的参数。众所周知.淬火温度对刀具,特别是对高速钢刀具的使用寿命有极大的影响。高速钢的淬火加热温度通常在1200～1300℃左右.多采用盐浴炉加热。在这样高的温度下
A temperature is the most important parameter in the heat treatment process. As we all know, the quenching temperature has a great influence on the service life of knives, especially for high speed steel knives. High-speed steel quenching heating temperature is usually about 1200 ~ 1300 ℃. Use more salt bath furnace heating. At such a high temperature
