稀土镁中间合金是生产球墨铸铁常用的球化剂,其质量如何直接影响到产品质量的好坏。我厂根据生产高韧性球铁的需要,应用1.5吨工频炉自制稀土镁中间合金,8年多来生产正常,质量良好,不仅满足了本厂生产的要求,还供应了省内一些单位。此种中间合金不但适用于本溪铁、邯郸铁、澳大利亚铁等料源,特别有利于钒钛铁的大量使用。球化处理时用量经济,球墨铸铁的性能优良,现简要介绍于后。一、合金配比合金的装入量按炉子额定容量40～
The rare earth magnesium master alloy is the nodular agent commonly used in the production of ductile iron, and how its quality directly affects the quality of products. I plant according to the production of high ductility ductile iron needs 1.5 tons of frequency furnace homemade rare earth magnesium alloy, more than eight years to produce normal, good quality, not only to meet the requirements of the factory production, but also supply some units in the province. This intermediate alloy not only applies to Benxi Iron, Handan Iron, Australia iron and other sources, in particular, is conducive to the extensive use of vanadium-titanium-iron. The amount of ball processing economy, ductile iron performance, now briefly introduced in the later. First, the alloy ratio of alloy loading by furnace rated capacity of 40 ~
