自从1957年第一台直接还原设备工业化生产以来,目前已建有60台直接还原设备,另有25台在计划或建造中。最近世界直接还原铁的生产能力维持在1900万 t 左右。占总生产能力75%以上的八个国家为:委内瑞拉(450万 t)、印度尼西亚(230万 t)、墨西哥(200万 t)、加拿大(160万 t)、西德(130万 t)、美国(110万 t)、尼日利亚(100万 t)和阿根廷(90万 t)。至1985年末,将具有年产能力1000万 t。目前,占现有直接还原生产能力80%以上的生产方法,主要是 HYL(1957年)法和Midrex(1967年)法。1983年,由于钢铁工业的衰退,市场需求
Since the first direct reduction facility was industrialized in 1957, 60 direct reduction facilities have been built and another 25 are under planning or construction. Recently the world’s direct reduction of iron production capacity remained at 19 million t or so. Eight countries account for more than 75% of total production capacity: Venezuela (4.5 million t), Indonesia (2.3 million t), Mexico (2 million t), Canada (1.6 million t), West Germany (1.3 million t) (1.1 million t), Nigeria (1 million t) and Argentina (900 000 t). By the end of 1985, it will have an annual capacity of 10 million tons. At present, the production methods accounting for more than 80% of the existing direct reduction production capacity are mainly HYL (1957) and Midrex (1967). In 1983, due to the recession of the steel industry, market demand
