RUT340蠕化品质控制

Control of Creeping Quality of Type RUT340

针对以前生产蠕墨铸铁时 ,蠕化品质不稳定的问题 ,通过实施严格的化学成分控制、采用含镁变质蠕化剂、蠕化孕育工艺革新等措施 ,使得 4# 焦炉设备生产中 ,蠕铁品质稳定 。

According to produce formerly vermicular graphite cast iron, creeping problem with instability quality , through the chemical composition control of strict enforcement, after both modification and creeping agent containing magnesium, and technology reformation of creeping inoculation were adopted, the quality of vermicular graphite cast iron to become stable and creeping rate to become high at No.4 coke furnace.
