The aggregate particles of self-flowing castables are spherical, and the construction method is pumping. It relies on its own gravity to flow and degas, so it is called self-flowing castables. Because the aggregates of self-flowing castables are spherical and have low water absorption, a suitable proportion of water reducer is added during construction to improve … Read more
Neutral linings for induction furnaces are usually made of acidic (silicon dioxide) or basic (magnesium oxide) compounds. It is very important to select the right refractory material for a given melting or holding application. The choice of refractory lining depends on many factors, such as melting temperature, holding time, volume, induction stirring, additives and alloying … Read more
Binder is a kind of amorphous refractory material, which is a material that binds refractory aggregates and powders and makes amorphous refractory materials strong. Aluminate cement is a kind of inorganic binder, which mainly makes amorphous refractory materials strong through the hydration of cement. Furnace Cement, aluminate cement is divided into calcium aluminate cement, barium … Read more
What material is used for the ramming material of the medium frequency furnace lining? The selection of ramming material for the medium frequency furnace lining depends on the atmosphere in the furnace. Because the atmosphere of the medium frequency furnace lining is divided into neutral, acidic, alkaline, and composite, and there are core induction and … Read more
Refractory plastics are made of 70~80% granular and powdery materials, 10~25% plastic clay, and other binders and appropriate plasticizers. They are in the form of hard mud paste and maintain high plasticity for a long time. Refractory plastics are mainly used in various heating furnaces that are not in direct contact with the melt. The … Read more
10%, 15%, and 20% (w) andalusite was introduced into low-cement high-aluminum castables to study the effect of andalusite addition on the high-temperature performance of the castables. The results show that the addition of andalusite can improve the volume stability of low-cement high-aluminum castables. With the increase of andalusite addition, its load softening temperature and high-temperature … Read more
Low-cement aluminum-magnesium Spinel Refractory Castable is an important material for ladle lining. It is mainly made of corundum, special grade alumina clinker, fused magnesia or high purity magnesia and magnesium-aluminum spinel, and is prepared using low cement technology. It is also called corundum or high aluminum-magnesium spinel refractory castable, also called composite aluminum-magnesium spinel refractory … Read more
Repairing boiler lining requires resistance to chemical erosion. Chemical erosion is generally acidic, neutral and alkaline, which is different. Choose the appropriate wear-resistant plastic according to the specific situation. Rongsheng amorphous refractory material manufacturer can customize wear-resistant plastic according to actual working conditions. Whether it is for repairing furnace lining or building a new refractory … Read more
It is not possible to not add a binder to Silica Refractory Clay, but the proportion of adding must be mastered. Because without a binder, the viscosity of siliceous fireclay is not enough and the bonding is not good. Therefore, a binder must be added to silica fireclay to increase the bonding and facilitate the … Read more
Induction furnaces require refractory ramming materials. Furnace linings for different purposes have different requirements for refractory materials. Induction furnaces can only work effectively if ramming materials that meet smelting conditions are used. Rongsheng Unshaped Refractory Material Manufacturer can provide high-quality refractory ramming materials for induction furnace linings. Contact us for free quotes. Requirements for the … Read more
