近年来,容量为10吨以上大容量感应炉的使用数量在不断地增长。感应炉熔化本身费用的增加,可因使用大量废钢以及获得更好的铸件性能而得到补偿。使合成铸铁组织稳定和不出现各种缺陷,无论从冶金上或经济上考虑都是重要的,孕育处理乃是达到此目的最常用的一种后处理方法。但是,在实际生产 In recent years, the capacity of more than 10 tons of high-capacity induction furnace is constantly increasing the number of use. The increased cost of induction furnace melting itself can be offset by the use of large amounts of scrap and better castings. To make synthetic cast iron stable and does not appear all kinds of defects, whether from the metallurgical or economic considerations are important, inoculation is to achieve this purpose is the most commonly used method of post-treatment. However, in actual production
