Blast furnace taphole bricks clay (another name is stemming )
Stemming is made of refractory aggregate ,fine powder ,anchoring agent and liquid .The water content of foam mud is less than 2% . After calcination treatment ,it can form plastic refractory used as plugging off the tapping hole on blast furnace .
So far , there are two kinds of stemming ,one is water stemming , another is waterless stemming .
The water used as a binder ,named water stemming ,the coke ,resin and some organic materials used as a binder ,named waterless stemming.
1.The product is suitable for large, medium and small blast furnace, with high strength, low dosage, slag corrosion resistance;
2.It Can effectively stabilize the depth of the tap hole ,discharge iron slag；
3.No reaming ,no yellow fume , controlling the speed of iron melt .
4.It Can effectively reduce the labor intensity of workers, eliminate hiddendanger .
