Welcome to inquire! Contact: Yang Kuaixiao. China in the early 1950s began to use Portland cement castable refractory castable, then known as heat-resistant concrete, mainly for the following 700 ℃ (sometimes 700 ~ 1200 ℃) thermal structures, from 1965 to 1975 general aluminum calcium phosphate cement and refractory castable, then known as refractory concrete, the use of temperature to 1400 ~ 1600 ℃, during the construction of the production base, product standards established early in 1976, after 1976, the product range rapidly increased gradually improve the quality of the mid-1980s, China has developed a new generation of refractory castable, including low cement, ultra-low cement and non-cement castable refractory castable price, its quality is close to the international advanced level. One kind of blast furnace air duct (gooseneck, elbow, straight blowpipe) lined with monolithic refractories. Solves the blast furnace of clay pipes (gooseneck, elbow, straight blowpipe) lining the widespread use of ramming, high alumina, corundum castable refractory castable poor thermal stability wholesale, low intensity, intolerance hot air scour easy to crack cause redness duct technical problems. The castable using reasonable size grading of sintered bauxite, magnesite as raw materials, additives and binders for Silica refractory castable sales by mechanical agitation to form a uniform set of dry material, the use of add water and stir, using pouring vibrators forming, after drying and put into use. For blast furnace air duct (gooseneck, elbow, straight blowpipe) lining.
