平炉吹氧强化提高生产率已为实践证明是有效的措施,但还存在炉令低和用了氧未相应地节油等问题。为了逐步解决这些问题,鞍钢第二炼钢厂在平炉吹氧攻关中,首先从改进补炉和造渣等操作入手,使炉渣良好;初步解决炉底涨高问题,使炉型正常,大大改善了冶炼及炉顶工作条件。在此基础上,于七七年元月开始在17号平炉(顶吹氧)试验了新的热工制度,其特点是吹氧期
Open-hearth oxygenation to enhance productivity has proved to be effective measures in practice, but there are still low furnace and the use of oxygen is not the appropriate fuel-saving and other issues. In order to solve these problems step by step, Anshan Iron and Steel No. 2 Iron and Steel Mill blast furnace Oxygenation in the attack, the first from improving the furnace and slagging and other operations start to make the slag good; initial solution to the problem of floor elevation, the furnace normal, greatly improved Smelting and roof working conditions. On this basis, a new thermal system was tested at No. 17 open hearth (top blowing oxygen) from January of the beginning of January 1977 and was characterized by an oxygen blowing period
