chromium is an alloying agent used in steel and various nickel based and cobalt based superalloys, aluminium base alloys, electrical resistance alloys, hard facing grains and powders, and for electroplating.
铬是一种合金添加剂,用于钢材和各种镍基的和钴基的超耐热合金、铝基合金和电阻合金、表面硬化磨料及用于电镀。
in addition to adequate mine capacity, capital investments in downstream capacity (processing, value adding, refining and metal alloying) are crucial in this process.
在这一过程中,除充足的矿藏以外,对下游能力(加工、增值、提炼与合金制造)的投资也十分重要。
(ii) for the smelting, including the alloying, of non-ferrous metals, including recovered products (refining, foundry casting, etc.), with a melting capacity exceeding 4 tons per day for lead and cadmium or 20 tons per day for all other metals;
包括回收产品在内的有色金属熔炼,包括合金工艺(精炼、浇铸等等),铅和镉熔炼能力超过每天4吨,所有其他金属熔炼能力超过每天20吨;
