目前锰铁高炉炉身、炉腰部分的炉衬,仍然是影响一代寿命最薄弱的环节。一般情况下,最多使用二年炉衬即行全部脱落。由于内型改变,不仅引起生产失常,,燃料消耗升高,同时还威胁到钢壳的安全。因此,不得不频繁进行中修砌衬,在经济上造成了很大损失。一九六七年,阳泉钢铁厂在砖衬脱落的锰铁高炉上,采用炉外喷水冷却、扩大料钟和抑制边缘气流的方法,依靠在钢壳内部的自形料衬,维持了正常生产四年之久。而后,在1971年与1977年,分别改建了炉外喷水冷却和采用全炉冷却壁汽化冷却的自形料衬高炉 At present, the lining of the hearth and the waist of the ferromanganese blast furnace is still the weakest link that affects the life of the generation. Under normal circumstances, the maximum use of two years lining that line all off. Due to the change of internal shape, it not only causes the production abnormality but also increases the fuel consumption, at the same time it also threatens the safety of the steel shell. Therefore, it has to be frequently repaired in lining, resulting in great economic losses. In 1967, the Yangquan Iron and Steel Plant used a method of cooling water outside the furnace, expanding the chime and suppressing the flow of air on the ferromanganese blast furnace with the brick lining falling off, and maintained its normal condition by relying on the self-forming lining inside the steel shell Production for four years. Then, in 1971 and 1977, respectively, the transformation of the water outside the furnace cooling and the use of furnace cooling wall vaporization self-shaped lining furnace
