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.

Team style

Our company has hired super experts and social activists from the fields of scientific research, production, economy, business community and education, joining hands with universities and research institutions to commit ourselves to new metallurgical material and new technology processing, production, research and development and utilization. We have two large metallurgical material production bases, including hydrometallurgy, two key laboratories, a metallurgical material testing center and dozens of senior researchers. We focus on metallurgical material research, production and operation. On one hand, we concentrate on the production, processing and sale of ferroalloy, steel, pig iron, trace element and other metallurgical material and our refractory products and other products are exported to more than 10 countries and regions. On the other hand, we undertake such businesses as special research, market research and feasibility study and development. Our company recruits foreign investment for consultation, training, technology transfer and technology renovation.

We highly welcome domestic and overseas economic entities to join us. We'd like to seek for win-win common development to make a contribution to the revitalization of the national economy.
