1962年8月,鞍钢在一座炉缸直径6.5米的高炉上开始进行了风口喷吹重油试验。试验工作者首先研究了各国高炉喷吹重油的设备,结合鞍钢的具体情况,设计了一个简单的供油系统。其特点是使用一个蒸汽驱动往复式油泵集中供油,而经过一个输油围管分配至各风口。仅在总油管上装了一个ППЭ型流量计和特制的调节阀以控制油量。风口水套也稍加改造,用ф8×1冷拔耐热钢管制成的喷咀旋在风口上。为了改进油的燃烧,风口加长至420毫米。试验共分为4个阶段,油量分别为30、40、60、75公斤/
August 1962, Angang in a hearth diameter of 6.5 meters on the blast furnace began blowing heavy oil test. Experimental workers first studied the blast furnace heavy oil injection equipment, combined with the specific circumstances of Ansteel, designed a simple fuel supply system. Its feature is the use of a steam-driven reciprocating pump centralized fuel supply, and after a pipeline around the distribution to the outlet. Only one ППЭ-type flow meter and a special control valve are installed on the main pipe to control the amount of oil. Tuyere water jacket is also slightly modified, with ф8 × 1 cold drawn heat-resistant steel nozzle spin on the tuyere. In order to improve the combustion of oil, the tuyere is lengthened to 420 mm. Test is divided into four stages, the oil was 30,40,60,75 kg /
