为缓解煤源缺乏的现状,提高煤焦置换比,大幅度增产节焦降低成本,进一步完善高炉富氧鼓风喷煤工艺,西钢炼铁总厂进行了烟煤和无烟煤混喷试验。根据混喷的要求,制定了《烟煤和无烟煤配比混喷工艺方案》,试验过程中严格按照混喷安全措施的要求,认真执行配比混喷工艺方案,在系统设备没彻底改造的前提下实现
In order to alleviate the current situation of the lack of coal sources, improve the coal-coal replacement ratio, greatly increase the production of coke to reduce costs, and further improve the blast furnace oxygen-rich blast coal injection process, Xigang Iron and Steel Plant conducted a bituminous coal and anthracite mixed spray test. According to the requirements of mixed spray, developed a “mixed bituminous coal and anthracite mixed spray process,” the test process in strict accordance with the requirements of mixed spray safety measures, the implementation of the proportion of mixed spray process plan, the system equipment is not completely under the premise of transformation achieve
