一、钢铁工业用氧的发展概况据1961～1962年资料报道,全世界氧气生产总量达72000吨/日(折合54×10~6米~3/日),其中资本主义国家产量占75%,社会主义国家占25%左右,并且以每年10～20%的增长率在发展中。这些氧气的使用分配情况:化工用氧占49%,钢铁工业占41%,其他占10%。氧气在钢铁工业中大量的使用,是在第二次大战之后由于大容量制氧设备制成,氧气能以较低的成本生产以后才获实现。1952年以前,还只是在高炉、平炉、电炉、火
I. Development of Oxygen Industry in the Iron and Steel Industry According to the data from 1961 to 1962, the total oxygen production in the world reached 72,000 tons / day (equivalent to 54 × 10-6 m 3 / day), of which the output of capitalist countries accounted for 75% The socialist countries account for about 25% of the total population and are growing at a rate of 10% to 20% per annum. The use of these oxygen distribution: chemical oxygen accounted for 49%, steel industry accounted for 41%, the other 10%. The large amount of oxygen used in the steel industry was achieved after the Second World War due to the large oxygen capacity of oxygen equipment that could be produced at a lower cost. Before 1952, only in the blast furnace, open hearth, electric stove, fire
