宇航工业使用的高温合金材料,由于产品的特殊要求,在加工过程中产生大量的高温合金废料(一般成材率仅40～50％),其中含有较高的合金元素镍、铬、钨、钼。如何充分、合理地利用这些合金元素是我国金属回收行业多年来有待解决的课题。根据国家经委节能办公室和国家物资总局的指示,为了合理的利用高温合金废料,提高钢坯轧制前的加热质量,八一年十月,
Due to the special requirements of the products, the high-temperature alloy materials used by the aerospace industry produce a large amount of high-temperature alloy scrap (usually only 40-50% of finished products) during processing, and contain high alloying elements of nickel, chromium, tungsten and molybdenum. How to fully and reasonably utilize these alloying elements is a subject to be solved by the metal recycling industry in China for many years. According to the instructions of the State Economic Commission Energy Saving Office and the State Administration of Materials, in order to make rational use of the superalloy scrap and improve the heating quality before the billet rolling, in October of 1981,
