工装模具在热处理过程中往往会发生脱碳,特别是高碳钢模具的脱碳倾向更大,以致虽经精加工仍不能达到技术要求,造成很多模具报废。为此,我们对脱碳的锻冲压模经行补充微量碳氮共渗经验,取得良好效果。 Tooling die in the heat treatment process often occurs decarburization, especially high carbon steel mold decarburization tendency is greater, even though the finishing can not meet the technical requirements, resulting in a lot of mold scrapped. To this end, we have decalcified forging stamping die by adding trace carbonitriding experience, and achieved good results.
