丹阳钢铁厂有15m~3小高炉一座。在冶金部与省冶金局的关怀下,77年建了一座能力为150m~3/小时的制氧车间,供高炉送氧,以达增产与降焦之目的。于77年制定了高炉氧油雾化及高炉富氧的技术工艺流程,通过试验效果是显著的。78年9月高炉曾富氧加喷吹重油,利用系数达4.0以上,焦比达600kg/吨以下,但由于没有计量设备。所以没有得到数据。11月20日至月底正式做了氧油雾化试验,产量提高9.7％,焦比下降15.5％,燃料比下降6.6％,高炉顺行,作操稳定,现将情况简要介绍如下:
Danyang Iron and Steel Plant has a 15m ~ 3 small blast furnace. In the concern of the Ministry of Metallurgy and the Provincial Metallurgical Bureau, an oxygen-making workshop with a capacity of 150m3 / h was built in 1977 to supply oxygen to the blast furnace for the purpose of increasing production and lowering the coke. In 1977 developed a blast furnace oxygen atomization and blast furnace oxygen technology process, through the test results are significant. September 78 blast furnace oxygen enrichment plus injection heavy oil, the utilization factor of 4.0 or more, coke up to 600kg / ton, but because there is no metering equipment. So I did not get the data. November 20 to the end of the official oxygen atomization test done, the output increased by 9.7%, 15.5% reduction in coke ratio, the fuel ratio decreased by 6.6%, blast furnace in a row, for the operation of stability, the situation is briefly described as follows:
