This anti-seepage castable is low in conductivity and impermeable, effectively shielding against molten metal. With a corundum-molybdenum-micron powder framework and incorporating a composite anti-wetting agent, it can operate continuously at 850-1000℃. Its large contact angle and high surface tension with molten aluminum, lead, and cryolite prevent the molten metal from spreading and penetrating, thus limiting … Read more
With continuous updates, rotary kiln lining materials are no longer limited to a single method. Currently, there are refractory brick linings, monolithic refractory castable linings, and linings made of a 50/50 mix of precast components and castables. Furthermore, the refractory insulation system is constantly being upgraded, resulting in lower kiln surface temperatures and greater energy … Read more
The material composition of refractory spray coatings is basically similar to that of similar refractory castables. The difference lies in the smaller critical particle size of the refractory aggregate, typically 3-5 mm, and the application method is spraying. The combined amount of refractory powder, ultrafine powder, and binder is relatively high, generally 35-45%. Spraying is … Read more
In industrial kiln construction and maintenance, refractory materials are the “steel guardians” protecting high-temperature production. Refractory plastics, refractory ramming mixes, and refractory spray coatings, with their unique construction and application advantages, have become widely used monolithic refractories. What are the differences between these three? Rongsheng Monolithic Refractories Manufacturer, based on years of production and sales … Read more
Preparation for construction. In accordance with the design size requirements, check and accept the construction quality of the previous process and clean up the site. Transport the forced mixer, insert vibrator (vibrator) and trolley and other machinery to the site, install them in place, and test run them normally. It should be pointed out that … Read more
With the development of monolithic refractory castables, the proportion of castables used in heating furnace linings is increasing. Among them, low-cement self-flowing castables are becoming more widely used and account for a larger proportion. By rationally selecting raw materials and particle size distribution, and introducing ultrafine powders and high-efficiency dispersants, a self-flowing castable for heating … Read more
Micro-expansion refractory castables are a new type of refractory castable developed using clay-bonded and low-cement castable technologies. They are primarily used in various thermal equipment, such as steel rolling mills, achieving satisfactory economic benefits. Steel rolling mills are numerous and numerous, operating temperatures generally below 1400°C, and they operate intermittently, requiring shutdowns and cooling every … Read more
Refractory plastic is a material composed of refractory aggregates of a defined particle size distribution, powders, binders, and admixtures, which are then mixed, kneaded, and extruded into blocks or lumps. This amorphous refractory material retains excellent plasticity after a period of packaging and storage, allowing it to be applied by ramming. Refractory plastic offers advantages … Read more
Monolithic refractories are primarily used in irregularly shaped or deformed areas of new dry-process cement kilns, such as the preheating system, kiln tail, kiln head, coal injection nozzles, tertiary air ducts, coolers, and waste heat power generation. Monolithic refractories come in a wide variety of types, with significantly varying performance. Construction and maintenance significantly impact … Read more
With the implementation of the dual carbon strategy, high-temperature industries are facing increasingly stringent requirements for energy conservation and environmental protection, leading to an increase in the research and use of lightweight refractory materials. Mullite castables offer excellent properties such as a high refractoriness under load, good thermal shock resistance, and strong erosion resistance. They … Read more
