1995年以来,在总厂正确领导下,铁前工作有明显进步,炼铁厂加强管理,立足挖潜,生产一年上一个台阶,扭转了落后局面。 1.铁前工作的进步,向高炉提供质量较好、数量较足的烧结矿 1994年以后,综合料场投用,烧结矿成分渐趋稳定。我厂富矿粉大部分属褐铁矿,造球性能差,烧结矿成品率低,粉末多,强度差,1995年3月,在烧结混合料中配15~20%的澳矿粉,造球性能改善,提高料层透气性,从而提高垂直烧结速度、利用系数,强度也明显提高,烧结矿产量二年间提高了一倍,同时,由于烧结矿改为皮带上矿槽,槽上多一道筛,使入炉粉末由过去15~25%减少到8%左右。
Since 1995, under the correct leadership of the General Works, there has been notable progress in the pre-iron work. Ironworks has stepped up its management and based on tapping potential, producing a year to a higher level, reversing the backwardness. 1. The progress of the iron work before, to the blast furnace to provide better quality, adequate quantity of sinter After 1994, the integrated field put into use, sinter gradually stabilize the composition. Most of our ore-rich ore is a limonite with poor pelletizing performance, low sinter finished product yield, many powders and poor strength. In March 1995, the ore mixture was mixed with 15-20% Improve performance, improve the permeability of the material layer, thereby enhancing the vertical sintering speed, the use of coefficient, the strength has also significantly improved, sinter ore output doubled in two years, at the same time, as the sinter to the belt on the trough, slot more than a sieve , So that the furnace powder from the past 15 ~ 25% reduced to about 8%.
