        按 using/adopting cooling different, true 空淬火 can separation is true cold 淬火, true gas cold 淬火, true water cold and true salt and other temperature 淬火. mold true hot in main applications is true cold 淬火, true gas cold and true 空回火. is maintain parts (如 mold) true add hot excellent features, cooling agent and cooling process selection and made non important, mold process main/primary using/adopting cold and gas cold.

         true hot technology is year development 起 一 types new type hot technology, it tool features, positive is mold manufacturing in need, ratio anti add hot oxidation and carbon, true gas or remove gas,消 remove hydrogen 脆, from improve/increase material (parts) property, tough property and fatigue strong/high degree. true add hot slow, parts inner outer temperature relatively small and other factors,决定 true hot process formed parts deformation small and other.

         for/regarding hot rear again machine processing mold as 面,淬火 rear can can using/adopting true 空回火, especially is true 空淬火 工 parts (mold), it can improve/increase and surface quality related mechanical properties,如 fatigue property can, surface light degree, 而腐蚀 property and other.

         hot process machine technology (包括组织模拟 and property can forecast technology) formed development and application, make mold can hot formed is can can. due to mold production small amount (甚至 is mono parts), more product types features,以 and for hot property can requirements high and 不允许出现 waste product features, also make mold can hot formed is must. mold can hot 处理包括:明确 mold structure, use 材, hot property can requirements mold add hot process temperature degree 场, force distribution machine mold cooling process temperature degree 场, versus process and force distribution machine add hot and cooling process process true process made hot equipment 自动化 control technology.

        国 outer industrial 发达国家,如 USA, Japan and other, in true high pressure gas 淬方面, already 经开展 this technology R&D, main/primary for target/goal is mold.
