一、高速钢工件淬火加热温度的确定高速钢的优良性能,只有通过正确的淬火及回火才能充分发挥出来,淬火与回火质量的好坏是决定高速钢工件热处理质量的关键。高速钢的回火温度基本上是一致的,而各种牌号的高速钢其淬火温度却不相同。虽然每一种牌号的高速钢,都有它规定的加热温度范围,但在各种不同情况下的高速钢工件,又各有其具体合适的加热温度。如淬火温度过低,合金碳化物溶解不充分,奥氏体中谈
First, the high-speed steel quenching heating temperature to determine the excellent performance of high-speed steel, only through the correct quenching and tempering can be fully exerted, quenching and tempering quality is the key to determining the quality of high-speed steel heat treatment. High-speed steel tempering temperature is basically the same, and various grades of high-speed steel quenching temperature is not the same. Although each grade of high-speed steel, it has the heating temperature range, but in a variety of different cases of high-speed steel, each have their own specific suitable heating temperature. Such as quenching temperature is too low, the alloy carbide is not fully dissolved, austenitic talk
