新钢公司第二炼钢厂通过优选砌包材料、优化砌包工艺等手段.使精炼钢包包龄明显提高,增效显著.用包包龄由过去平均五十一点七炉上升到平均九十一点五炉,提高了百分之七十六点九八,吨钢成本下降六点七八.过去,该厂精炼钢包的砌筑工艺是采用镁碳砖砌筑包渣线,蓁部位砌筑高铝砖.采用这一工艺砌筑的精炼钢包包龄低,渣线部位的镁碳砖寿命与其它部位不能同步,导致镁碳砖浪费严重,而钢水冲刷部位侵蚀严重,又造成频繁补包,既增加了工人的工作量,又给钢水质量带来不利影响,严重影响钢包的速周转.为了发这一善,该厂浇钢车间部分人员在厂有部部门及领导的支持下,大胆提出了钢包全砌镁碳砖的砌筑工艺,在砌筑过程中,采用合理搭配各种砖型、精心调制泥料、紧密结口
The second steelmaking plant of Xingang Steel Co., Ltd. optimized the masonry materials and optimized the masonry process to make the refining steel ladle age significantly higher and the synergistic effect remarkably increased. From the average past 51.7 furnaces to the average of nine Eleventh Five-furnace, an increase of 76.98 tons, a ton of steel costs down 6.78 in the past, the factory masonry ladle refining process is the use of magnesia carbon brick masonry slag line, Masonry high alumina bricks.With this process masonry, low-grade steel smelting, slag line part of the life of magnesia and other parts can not be synchronized, resulting in serious waste of magnesium carbon bricks, and erosion of molten steel serious erosion, but also caused frequent Bundan not only increase the workload of workers, but also adversely affect the quality of molten steel, seriously affecting the ladle rapid turnover.In order to send this kind of good, the plant part of the plant personnel in the steel plant in the plant department and leadership support, Boldly proposed ladle full masonry brick masonry process, masonry process, with a reasonable mix of brick, carefully prepared mud, close knot
