摘要
介绍使4JB1铸态球铁曲轴性能达到QT800-2牌号要求的工艺措施。这些措施包括:采用覆砂铁型浇注,控制开型时间,加入适量合金元素,采用含锑球化剂和随流孕育等。
a:The measures to enable the as-cast properties of4JB1model crankshaft to achieve800MPa of tensile strentgth and2%of elongation were described .The measures were:pouring in permanent mould with resin sand facing,knocking-out at fixed time interval,adding proper amount of alloying el-ements,applying Sb-containing nodulizing alloy and adopting stream inoculation,etc.
