象宝钢1号高炉这样大型的高压高炉,要持续稳产,炉前稳定是很关键的因素,而其中铁口泥套的制作和使用寿命又是重要一环。宝钢1号高炉开炉初期采用日本进口的捣打料来制作铁口泥套。这种泥套在产量较低的情况下尚可维持生产,但随着产量不断提高,捣打料经常损坏、冒泥而影响铁口 As Baosteel No. 1 blast furnace such a large high-pressure blast furnace, to continue stable, stable front of the furnace is a key factor, of which the production and life of iron mud cover is an important part. Baosteel Blast Furnace No. 1 at the beginning of the early use of imported ramming batches to make iron mouth mud sets. This mud cover in the case of lower yields can still maintain production, but with the continuous increase in production, Ramming often damaged, mud and affect the iron mouth
