“JUCOS REFRACTORY” – Your trusted Refractory Products Supplier.
In view of its physical and chemical properties, it is one of the known high-quality refractory materials. In addition to being used as high-grade refractory materials for the smelting industry, and raw materials for the technical ceramic industry. It can also be used to smelt high-strength lightweight silicon-aluminum alloys to produce metal fibers and guide-type supersonic aircraft and spacecraft. According to reports, mullite is still used abroad to gasify coal and make radomes. Some of them are well-crystallized and bright in color and can also be used to make crafts and decorations. Since the 1970s, it has been widely valued by China’s industrial production, and its application areas are also expanding rapidly. The mullite formed after calcination has high refractoriness, chemical stability and mechanical strength, so it is widely used in metallurgy, building materials and other industrial sectors.
As refractory
This has special benefits for improving high-temperature operations and other metallurgical processes. Unshaped refractory is directly used without firing, which can save fuel energy, and its volume stability at high temperatures will have a great impact on its service life. In the practice of Yuqi refractories, if the fired injection and plastics are used according to the proportion, they will contain a certain amount of clay and inorganic binders, which will cause the unshaped refractories to shrink during the high temperature and cooling process, cracks, peeling, and shortening. The service life of refractory materials. In order to control and reduce the shrinkage of refractory products under long-term high temperature, if a certain amount of andalusite is added to the ingredients and the expansion and stability characteristics are used, the above-mentioned small shrinkage phenomenon of the amorphous material can be eliminated, and the service life of the material can be extended up to five years as long as.
Refractory brick
Andalusite is calcined to make profiles, which can be used in key parts such as hot blast stoves, hot blast towers, and reheating. It can also be used for various auxiliary casting and operating equipment, and can also be used to make kiln facilities, high-temperature aluminosilicate insulators, and sand moulding fabrics. Using refractory fiber made of it as furnace lining can save energy by 30-50% compared with refractory soil or lightweight brick furnace lining. In addition to reducing fuel consumption and increasing stability, this refractory brick can also save more than 40% of the consumption of general refractory materials.
Raw material for the production of silicon-aluminum alloy, alumina and aluminum metal: Because of the high content of andalusite Al2O3 and low content of oxides such as iron, titanium and calcium, it is not necessary to use alumina when used to produce silicon-aluminum alloy with 60% aluminum. It can simplify production procedures and improve production efficiency.
