Heavy castable means the bulk density greater than 1800kg / m3 of castable. Press material matrix can be divided into: Chromium corundum, corundum, corundum mullite, high alumina, clay and other refractory castable. Press the binding agent can be divided into: cement, chemical bonding, binding and other clay refractory castable. According to the construction process can be divided into: gravity, vibration, ramming, plastic, coating, no mixing and other refractory castable. Various industries as well as specialized precision classification for each environment various casting materials, such as iron and steel industry, the petrochemical industry, non-ferrous metal industry, glass industry, furnace refractory castable. Tianjin Gute energy saving Technology Co., Ltd. can produce a variety of national standards for grades of castable, also according to customer requirements, various conditions for specialized development, production castable. Ladle castable having slag resistance and slag penetration and good. Depending on the size of the ladle, refined style and proportions of the different, select the appropriate grade of aluminum-magnesium casting material. Where long-life high-grade aluminum-magnesium casting material chemical composition: Al2O3 MgO> 96%, MgO> 5%; SiO2 <1.5%; Fe2O3 <0.5%. Former ladle castable construction process 1 stirring to ensure mixing equipment clean and free of debris, no other material mixed. 2. To be familiar with the device before stirring state, ready for weighing apparatus according to the size and requirements to ensure correct. 3. castable added to the mixer, the first dry mix for 2-5 minutes, stopping to view the kneaded state, to ensure that no delamination occurs, add water mix evenly from about 5.2 to 5.5 percent, while stirring, add water, first to the total amount 80%, wet-mixed for 6 minutes, then added, as appropriate, according to the material of Henan alumina balloons castable, castable until uniform, the rear surface discharge plasma Fujian Pan-alumina hollow ball casting material, generally underwrite slightly dry, package wall relatively little wet. 4. Make sure that each stirring time stirring consistent amount of water craft. Found materials dry or wet, can be reconstituted back into the machine, the material temporarily prohibited in playing water or feed. 5. Stir the material should be poured within 15 - 25 minutes to complete, so as not to inconvenience casting long home sclerosis, affecting the structural strength of the ladle lining 6. Each time the construction is completed or when changing the casting material varieties will clean mixer. 7. Never stop halfway stirring job, such as blenders failure at work, if the short time to repair, before opening the machine to boot must press shall be removed alumina hollow ball after 1/2 and above material castable, after boot then this part of material inputs, discovery can not be repaired, it must be castable clear the machine, cleaning equipment.
