Several different cooling slot shapes of continuous casting mold are designed base on the fin optimization theory, and then compared them with existing cooling slot shapes. 根据肋传热理论,提出几种具有较高传热效率的连铸用结晶器水缝形式,并与现有的几种水缝形式作了比较。
The casting method using multi& step gates with fin overflow feeders has effectively prevented heat insulation valve castings from forming blowhole defects. 采用阶梯式浇口配合飞边冒口溢流的铸造工艺,有效地消除了保温阀阀体铸件的气孔缺陷。
