目前大部分炉子的损坏原因不是全部炉衬被蚀薄,而是因为局部严重的损坏而被迫停炉。根据这种情况,正确的选择炉型、耐火材料及改善砌砖方法是提高炉龄、节约耐火材料的重要措施之一。石景山钢鉄公司(以下简称石钢)3吨侧吹转炉由于在砌炉及其他方面的一些改进,故使炉子寿命显著提高了。11月下旬12月初平均炉龄由10月份19炉提高到56炉以上,最高达82炉。一、炉子的一般情况 (1)耐火材料:石钢砌炉用的衬砖依其形状、尺寸来分共有12种,其中除风眼砖用焦油镁砂打结外,其他各种砖均用焦油白云石打结。其主要化学成分列于表1。
At present, most of the furnaces are not damaged due to the fact that not all the linings are eroded, but are forced to shut down because of serious localized damage. According to this situation, the correct choice of furnace type, refractory materials and improve the method of bricklaying is to improve furnace age, one of the important measures to save refractory material. Shijingshan Steel 鉄 Company (hereinafter referred to as Shi Gang) 3-ton side of the converter because of the furnace and other improvements in the furnace, so the furnace life significantly increased. The average furnace temperature in late November and early December increased from 19 furnaces in October to 56 furnaces and up to 82 furnaces. First, the general situation of the furnace (1) Refractory: stone brick lining brick with its shape, size, there are a total of 12 species, in addition to eye-blown brick with tar magnesia knot, the other kinds of bricks are used Tar dolomite knotted. The main chemical composition is shown in Table 1.
