摘要
精炼工序采用铝脱氧易产生钢水下流不好现象,影响生产顺行;铝脱氧的精炼成本较高,精炼周期较长。对Als没有要求的钢种,在转炉出钢过程中加小粒灰、热态精炼钢渣再利用、使用非铝基脱氧剂和根据钢中Als含量进行钙处理等措施,钢水可浇性连续11个月达到100%,缩短了精炼周期,降低了电耗、电极消耗和渣料消耗等。
To adopt aluminum - deoxidation in refining stage would bring about defects ： molten steel flowing down to affect steady production, higher cost and longer refining cycle. For those steel grades no demand for Als, with the following measures adopted the castability of molten steel reached 100% in continuous 11 months： adding small - size particle of ash, reusing hot refining steel slag, using non AI deoxidizer and treating calcium according to the content of Als in steel. That shortens refining cycle, reduces electricity consumption, electrode consumption and slag materials consumption.
