Damage Mechanism of Environment Friendly Anhydrous Stemming

The blast furnace stemming is used to block the taphole. When the blast furnace does not produce liquid iron slag, stemming filled in the iron mouth, the iron mouth maintain a certain depth. When blast furnace produce iron, some channels are drilled out on the core of the stemming, and liquid iron slag is discharged out of the furnace through the channel. During this period, it is required that the aperture of the iron hole is stable, the iron size is uniform and the tapping time is long. Becasue the blast furnace outlet must be opened and blocked repeatedly, it's required that the stemming needs to be easy sintering, easy opening and erosion resistant. The stemming is erosioned by slag chemicals because the SiO2, CaO, MgO and FeO in the slag are chemically reacted with the stemming at high temperature to produce the iron periolite 2FeO, SiO and iron pansy 2FeO, Ai2O3, SiO2 etc. These low-melting additives becoming liquid slag flow out in the process of tapping.

If the quality of blast furnace stemming is not good, there will appear tidal iron mouth, broken iron mouth, opening difficulty, shallow iron mouth, deterioration of the working condition, etc., which affect the normal production of blast furnace.
