在容量为22500千伏安的封闭炉上进行了使用加水的炭素还原剂熔炼硅铁的试验。图1和图2为加水结构示意图。炉料中的炭素还原剂是由60％冶金焦和40％半焦组成,其粒度为5—20毫米。炉料由配料小车1放出后藉助于喷雾嘴2喷洒工业用水。炉料在沿着料管3、弯管和位于高温区的料斗4自动 A trial of smelting ferrosilicon using a carbonaceous reducing agent plus water was carried out in a closed furnace with a capacity of 22,500 KVA. Figure 1 and Figure 2 for the water structure diagram. The carbonaceous reductant in the charge consisted of 60% metallurgical coke and 40% semi-coke with a particle size of 5-20 mm. The charge is dispensed by the dispensing trolley 1 and sprayed with industrial water through the spray nozzle 2. Burden is automatic along the tube 3, the elbow and the hopper 4 in the hot zone
