在乌拉尔机器厂,已经掌握了用孕育铸铁制造大型铸件的方法,并且有效地解决了一系列关于收集大量铁水及浇铸方面的问题.为了提高孕育处理时的铁水温度,10~40%的铁水是在电炉或平炉中熔化,然后和冲天炉熔化的铁水在铁水包中混合.实际经验证明,这种液体孕育处理的铸铁质量业已获得改善.当铁水在铁水包内经过 At the Ural Machine Factory, it has been mastered the method of producing large castings with cast iron, and has effectively solved a series of problems concerning the collection of large amounts of molten iron and casting. In order to increase the temperature of hot metal during inoculation, 10 to 40% Melted in an electric or open hearth furnace and then mixed with hot metal melted in a cupola in a ladle. Practical experience has shown that the quality of the cast iron that is inoculated with this liquid has been improved. When hot metal passes through the ladle
