首钢炼钢厂2号30吨氧气顶吹转炉炉令于1978年5月14日达到2868炉.炉役共历时59天17小时26分钟,平均每炉产钢34.68吨.这个炉役在炉衬的主要部位首次大量使用合成镁白云石烧成油浸砖,配合用合成料、白云石料的轻烧油浸沥青结合砖进行综合砌炉.炉役过程中,铁水条件良好,并在原料、装入、供氧、造渣和温度制度方面采取措施,减缓对炉衬的浸蚀:整个炉衬显示良好的抗浸蚀性能,526炉开始于装料侧补炉,2073炉时炉衬局部见永久层后,以湿法喷补手段使炉龄延长800炉,炉衬耐火材料消耗3.19公斤/吨钢.这个炉役显示了“高产、优质、低耗、长寿”的良好效果.
The 30-ton oxygen top-blown converter at Shougang Steelworks No. 2 was ordered to reach 2,868 on May 14, 1978. The total length of the fireworks was 59 days, 17 hours and 26 minutes, and the average steel production was 34.68 tons per furnace. The main part of the first large-scale use of synthetic magnesium dolomite fired oil-impregnated bricks, with synthetic materials, dolomitic light burning oil-impregnated asphalt combined brick building furnace furnace during the hot metal condition, and the raw materials, , Oxygen supply, slagging and temperature control measures to reduce the erosion of the lining: the lining showed good resistance to corrosion performance, 526 furnace at the beginning of the filling furnace, furnace 2073 furnace lining see permanent layer, Extending the furnace length to 800 furnaces by means of wet blasting, the lining refractory material consumes 3.19 kg / t steel, which shows a good effect of “high yield, good quality, low consumption and long life”.
