我厂模具材料大多为T8、T10的碳素工具钢,热处理技术要求HRC62～64,变形量在±0.02毫米范围。过去我厂模具淬火(指碳工钢淬火)采用10％盐水-油双液淬火法,工件入水后凭听声音及振动的感觉来确定入水时间,若操作不当就会使模具变形和开裂。后来我们又采用了零件的断面每厚3～4毫米在冷却水中停留一秒钟计算工件入 Our factory mold materials are mostly T8, T10 carbon tool steel, heat treatment technology requirements HRC62 ~ 64, deformation in the range of ± 0.02 mm. In the past I plant quenching mold (referring to carbon steel quenching) with 10% brine - oil dual-liquid quenching method, the workpiece into the water after hearing the sound and vibration to determine the water into the water time, if improper operation will make the mold deformation and cracking. Later, we also used the part of the section of the thickness of 3 to 4 mm in the cooling water to stay a second calculation of the workpiece into
