摘    要:对低铬D型石墨灰铸铁的成分、组织和性能进行了研究。试验结果表明:选择适宜的基本元素(3.4%C、2.2%Si、0.5%Mn、<0.15%S、<0.12%P),控制Cr和Cu的含量分别为0.75%和0.7%,用湿砂型和下型安放大块冷铁的铸造工艺控制冷却速度,经热处理后,可获得具有良好石墨形态的D型石墨灰铸铁,其抗氧和热疲劳性能分别是普通灰铸铁的4.1倍和4.2倍,适于制作玻璃模具。

关 键 词:D型石墨  灰铸铁  抗氧化性  玻璃模具

Abstract:The compositions, microstructures and properties of D-type graphite grey cast iron with lower chromium have been studied. The experimental results show that by selecting appropriate general elements (3.4%C, 2.2%Si, 0.5%Mn, <0.15%S, <0.12% P) and alloying elements such as 0.75% of chromium and 0.7% of copper, using green-sand mold, putting chill iron in drag to control cooling rate,finer D-type graphite cast iron can be obtained after heating treatment, which is fitted to make the glass mold. The oxidation-resistance and heat-fatigue of D-type graphite grey cast iron are 4.1 times and 4.2 times larger than that of the general grey cast iron, respectively.
Keywords:D-type graphite  gray cast iron  oxidation resistance  glass mold
