我厂有一座28m~3小高炉,冶炼锰铁。我厂冶炼水平七五年比七四年好,七六年又比七五年好。(主要经济指标见附表)。除了高炉操作水平的提高及风电机等设备的相应增加以外,入炉原料、燃料的认真处理有很大的影响作用。毛主席指出:“管理也是社教”。我厂比较注意加强对原料的管理。本着“精、小、净、匀”的要求,提出:“块度大小要匀,入炉矿焦要净,炉料尽量要精。”现在把我厂入炉原料处理情况汇报如下:(1)严格破碎筛分,实现矿焦匀、净。破碎系统配上撞筛,实行分组筛分,大块返回重破,中块、小坎和粉末严格区分,分类归堆,利于高炉配料搭配使用。当筛面发 I plant a 28m ~ 3 small blast furnace, smelting ferromanganese. Our factory smelting level is better in 1975 than in 1974, and it is better than 75 in 1975. (The main economic indicators in the attached table). In addition to the improvement of blast furnace operation and the corresponding increase of wind turbines and other equipment, the careful handling of raw materials and fuels has a great effect. Chairman Mao pointed out: “Management is also a social education.” I plant more pay attention to strengthening the management of raw materials. In line with the requirements of “fine, small, net and even”, it is put forward: “The size of the block should be uniform, the furnace coke should be clean, the charge should be refined as far as possible.” Now, Strictly crushing and screening, to achieve uniform coal mine, net. Crushing system coupled with hit the screen, the implementation of grouping screening, heavy back heavy broken, the block, the small ridge and powder strict distinction, classified into heap, which is conducive to the use of blast furnace ingredients. When the screen surface hair
