包钢有色一厂提出的稀土硅铁镁合金及稀土硅铁合金,已经冶金部包钢批准,作为企业内部标准于1974年1月1日实施。该厂并按标准正式生产产品。其中稀土硅铁镁合金球化剂的成份,与各厂通常采用的球化剂成份相近。该厂采用减薄合金铸锭等措施,稀土镁合金中的偏析已达到技术要求。现将稀土硅铁镁合金等标准介绍如下:
The rare earth ferrosilicon magnesium alloy and rare earth ferrosilicon alloy proposed by Baotou Nonferrous Factory have been approved by Baotou Steel of Metallurgical Department as the internal standard of the enterprise and implemented on January 1, 1974. The factory and the official standard production of products. One rare earth ferrosilicon magnesium alloy nodulizer composition, and the plant commonly used nodulizer composition similar. The plant adopts thinning alloy ingot and other measures, rare earth magnesium alloy segregation has reached the technical requirements. Now rare earth ferrosilicon magnesium alloy and other standards are described below:
