Lightweight refractory castable refractory formulated from lightweight aggregate and powder, binders and additives made of pourable molding mix called lightweight refractory castable. Due to the small light casting material bulk density, low thermal conductivity, it has also become insulating refractory castable. A bulk density by Category (1) Semi-lightweight refractory castable refractories, the bulk density of 1.0--1.8g / cm3. (2) lightweight refractory castable, bulk density 0.4--1.0g / cm3. (3) super lightweight refractory castable, bulk density of less than 0.4g / cm3. B by using the temperature classification of light (heat) refractory castable can be divided into three categories: (1) low-temperature insulation (lightweight) refractory castable, temperature is 600--900 ℃. (2) temperature insulation (lightweight) refractory castable, use temperature 900--1200 ℃. (3) high-temperature insulation (lightweight) refractory castable, use temperature of> 1200 ℃. Refractories (Refractory material) kind of an acidic refractories (Refractory material) usually refers to the SiO2 content of more than 93% of refractories (Refractory material) refractory wholesale, its main feature is resistant to corrosion at high temperatures acidic residue, but Easy to react with alkaline slag. 2, basic refractory (basic refractory) generally refers to magnesium oxide or magnesium oxide and calcium oxide as the main component of refractories (Refractory material). Such refractories (Refractory material) refractoriness are high, and strong resistance to alkaline slag. 3, aluminum silicate refractories (Refractory material) refers to the SiO2-Al2O3 as a main component of refractories (Refractory material) refractory lowest, according to the number of the Al2O3 content may be divided into half-siliceous (Al2O3 15 ~ 30 %) refractories manufacturers, clay (Al2O3 30 ~ 48%), high alumina (Al2O3 greater than 48%) categories. 4, fused cast refractories (Refractory material) refers to a certain method after the high temperature batch material melted, cast into the refractory article having a certain shape.
