Shanghai Daoqin Plastics Co., Ltd.

         mold use non 常广泛, therefore for/regarding mold 钢 工 as conditions must meet/satisfy tool has high degree, strong/high degree, wear resistance, and tough property,以 and high property, hard property and other process property can. its mold in process property can upper need 知道四 large important key points.

        1, processing property

         is 指锻, hot processing properties and 切削, abrasion and other cold processing properties, it and chemical formed separation, quality, 组织状态 and 硫, 磷含经 and other has 关. mold large separation is has multiple alloy 元素, but also its content relatively high types, especially high carbon, high alloy 钢, in hot processing need control add hot made degree and cooling methods.以避免 or decrease/reduce hot processing waste in cold processing front,应 improvement 组织状态,以 decrease/reduce in cold processing process in tool abrasion loss,并 improve/increase mold surface quality.

        2, hot deformation and temperature degree.

         made formed mold,进行 most hot 处理时 requirements mold dimensions and 形状愈 stability good, therefore, in hot 处理时 for mold tool generate deformation degree requirements very 严, meanwhile. requirements temperature degree scope/range wide,以 decrease/reduce hot phenomenon.

        3, hard property and property

        淬 hard property main/primary and chemical formed separation especially is carbon amount has 关. property remove 决定于钢 chemical formed separation outer. also and in front 原始组织 has 关. mold for this types property requirements, according to different mold use conditions has heavy. 例如, for/regarding requirements surface tool has high hardness mold and tensile mold use 钢,淬 hard property relatively is heavy easy for/regarding requirements 整 截面 tool has uniform property can hot mold 钢,则淬透 property more is important.

        4, carbon property

         mold surface 发生脱 carbon,会 make mold surface mechanical properties reduce therefore requirements mold 钢 脱 carbon property low good. is, in same add hot conditions lower,钢 脱 carbon property 决定于钢 chemical formed separation, especially is carbon amount.
