BOF Refractories

Bottom Blowing Purge Plug Introduction:

The bottom blowing purge plug produced by Changxing Refractories use high quality magnesia-carbon bricks. Under normal conditions, the adequate pipes could guarantee the high rate of opening and stable gas flows of the purging plug and meet the demands of top-bottom gas purging at the same time. The particle gradation of aggregates, fine powders, binders or admixtures in the ingredients will have different effects on the strength, flexural resistance and thermal shock resistance of the Bottom Blowing Purge Plug.The bottom of the furnace mainly stores molten steel, which is subject to the erosion and penetration of flowing steel slag and molten steel.
