Blast furnace oral damage stemming mechanism: thermal chemical attack. Our extensive use of blast furnace sinter, only a small amount of pellets and ore, slag and iron is high, stemming prolonged contact with liquid iron and slag melt, prone to chemical reaction quality environmental water cannons mud, so stemming the erosion. The reaction of iron olivine (F2S) environmental water cannons mud wholesale, iron cordierite (F2AS5), Fe-Al tetra calcium (C4AF), manganese cordierite (2MnO · 2Al2O3 · 5SiO2) and other low-melting mineral phases in iron During the dry environment stemming prices, with molten iron slag erosion and loss of iron mouth aperture resorted to expand, resulting in rapid molten iron out of the mouth, the effect of iron mouth stable. Anhydrous stemming features: high-performance green water cannons mud is operating blast furnace refractories environmental protection with key features water cannons mud, play three functions: security blocked the late iron taphole; stable, smooth Emissions furnace slag of molten iron; by mushroom-shaped hearth formed inside balling, protection of hearth sidewall turn against erosion and corrosion, extending blast furnace life.
