自1998年以来,炼铁厂所用的炮泥虽然在配比、管理等方面采取了一些措施,但质量不稳定,难以适应目前的生产要求。2001年我厂外购部分无水炮泥,改善了铁口工作。但若使用量稍多,高炉成本难以承受,因此提高炮泥质量并合理控制炮泥成本、改善铁口工作迫在眉睫。 1 炮泥现状目前我厂根据各炉的情况制作两种炮泥——添加剂炮泥(供2号、3号、4号、5号炉)和Sic炮泥(供1号炉)。从使用效果看,都不理想,主要存在以下几个问题:一是含水量较高,
Since 1998, some measures have been taken in the proportioning and management of shotcrete used in the ironworks, but the quality is unstable and it is difficult to meet the current production requirements. In 2001, I outsourced part of the anhydrous stemming to improve the work of Tiekou. However, if the amount is slightly higher, the cost of the blast furnace will be unbearable. Therefore, it is imperative to improve the quality of shotcrete and to control the cost of shotcrete properly and to improve the work of making steel. 1 Sludge current situation Currently I plant according to the situation of the furnace to produce two kinds of stemming - additive gun mud (for 2, 3, 4, 5) and Sic stem mud (for the first furnace). From the use of results, are not ideal, the main problems are as follows: First, higher water content,
