摘要
介绍了采用消失模工艺铸造铸铁件提高浇注温度的原因,其中球铁浇注温度范围为:1380～1480℃,灰铸铁为1360～1420℃,合金铸铁(Cr系白口铁)为1380～1450℃;认为浇注温度过高容易引起粘砂、反喷、气孔等缺陷,浇注温度过低则易引起皱皮、冷隔等缺陷;提出了用消失模工艺生产灰铸铁、球墨铸铁、Cr系白口铸铁对铁液的调整要求。
The reason why relatively higher pouring temperature should be adopted for the lost foam iron castings was described.The pouring temperature was as follows：1 380～1 480 ℃ for the nodular iron;1 360～1 420 ℃ for the gray iron;1 380～1 450 ℃ for the Cr-alloyed cast iron（Cr series white cast iron）.Too high pouring temperature is easy to cause defects such as the burn on,metal injection from mold,blowhole,etc.,and however,too low pouring temperature is easy to cause elephant skin and cold shut.The measures to be adopted respectively to adjust the iron melt for production of gray iron,nodular iron and Cr-alloyed white iron proposed.
