近年来,全世界各地建立起一大批中、小型钢厂,至1984年为止,中小型钢厂的钢产量接近全世界钢总产量的20％,而在二十年前,仅占世界钢产量的2.5％。预计到本世纪末,将达到40％左右。很明显,中、小型钢厂将逐渐成为整个钢铁工业的重要因素。 小型钢厂的概念是从六十年代初期发展起来的,当时的年产量范围为5万—15万吨,主要用来生产钢筋和棒材,这种类型的工厂几乎都建在其产品销售市场的附近。由于小型钢厂生产不断扩大,有的所谓小型钢厂年产量超过100万吨,并生产各种高级产品,其规模已达到中型水平。故统称为中、小型钢厂。
In recent years, a large number of medium- and small-sized steel mills have been established all over the world. By 1984, the output of small and medium-sized steel mills was close to 20% of the world’s steel output. Only 20 years ago, 2.5%. It is estimated that by the end of this century, it will reach about 40%. Obviously, medium and small steel mills will gradually become an important factor in the entire steel industry. The concept of a small mills was developed from the early 1960s when the annual production ranged from 50,000 to 150,000 tons, mainly for the production of steel bars and rods. Almost all of these types of mills are built on their product sales market Near. As small-scale steel mills continue to expand their production, some so-called small steel mills have produced more than 1 million tons of annual output and have produced various kinds of advanced products. The scale has reached the medium level. It is collectively referred to as medium and small steel mills.
