Do you know the difference between high alumina fluidized steel bricks and clay fluidized steel bricks?
With the rapid development of society now, the flow of steel bricks as a common refractory materials, is widely used in various fields, because of its production process is divided into high alumina flow of steel bricks and clay flow of steel bricks.
With the rapid development of society now, the flow of steel bricks as a common refractory materials, is widely used in various fields, because of its production process is divided into high alumina flow of steel bricks and clay flow of steel bricks. In order to let you better understand, we first briefly understand the difference between the two.
High-alumina flow steel brick production and clay brick production process is similar, the difference is that the powder rubbing high aluminum clinker more, higher refractoriness than clay bricks, better resistance to acid and alkali candle performance, suitable for a variety of kiln firing belt, etc. Al2O3 content of more than 48% of the alumina brick collectively referred to as the high-alumina flow of steel bricks. According to the amount of Al2O3 content is divided into three levels: I (Al2O3>75%); II (Al2O3 60%-75%); III (Al2O3 48%-60%). According to the mineral composition, it can be classified into: low mullite (including sillimanite) and mullite (Al2O3 of 48%-71.8%), mullite-corundum and corundum-mullite (Al2O3 of 71.8%-95%), corundum (Al2O3 of 95%-100%) and other fluid steel bricks.
Clay bricks refer to the clay products with Al2O3 content of 30%-40% aluminum silicate material. It is made of 50% soft clay and 50% hard clay clinker, batching according to certain particle size requirements, molding, drying, and firing at a high temperature of 1300-1400 ℃. Its mineral composition is mainly kaolinite (Al2O3-2SiO2-2H2O) and 6%-7% impurities (oxides of potassium, sodium, calcium, titanium and iron). Clay flow steel brick firing process, mainly kaolinite continuous decomposition of water loss to generate mullite (3Al2O3-2SiO2) crystallization process. The SiO2 and Al2O3 in the firing process and impurities to form eutectic low melting point silicate, surrounded by mullite crystals. He belongs to the weak acid refractory products, can resist the erosion of acidic slag and acidic gases, slightly less resistant to alkaline substances.
Clay flow steel bricks have good thermal properties and are resistant to cold and heat. The refractoriness of flow steel brick clay is comparable to that of silicon brick, up to 1690-1730℃, but the load softening temperature is more than 200℃ lower than that of silicon brick.
