Firebricks（also called Refractory bricks）. Refractory materials made of refractory clay or other refractory raw materials. Light yellow or brownish. It is mainly used for building smelting furnaces and can withstand high temperatures of 1,580℃-1,770℃. Such as refractory clay brick, high alumina bric

In today's society, bauxite clinker has become an indispensable raw material in refractory castable industry, and no product can replace bauxite at present.So, what is high alumina refractory pouring material? Theoretically, aluminosilicate refractories with Al2O3 content greater than 46% are called

Thank to the progress of science and technology and the rapid development of society, the metallurgical industry has also developed rapidly. Bauxite in refractory industry usually refers to bauxite with alumina ≥48% and low iron oxide content after calcination. Bauxite is sintered at a high temperat

As we all know that Calcined Bauxite is widely used as Refractory Materials or used in Metallurgical Industry. Calcined Bauxite is a new senior aluminasilica refractories. It can be used as coating or stuccoing for lost wax casting and refractory aggregate for kinds of casting coating. With so many

Aluminum oxide is the main component of bauxite, and the higher the content of aluminum oxide, the higher the fire resistance. Silicon oxide is mostly present as aluminum silicate in clay, with a small amount present as free silicon oxide. Free silicon oxide can weaken the plasticity and bonding str

Refractory materials are industrial auxiliary materials, and industrial sectors such as metallurgy and steel consume a large amount of refractory materials, accounting for approximately 60% to 70% of their total; The building materials system includes industrial sectors such as cement, glass, and ce

SEPPE garnet sandblasting abrasive has high hardness, long lifetime, high efficiency, low consumption and high recycling rate.In the process of surface preparation, SEPPE garnet is blasted on to the surface of the steel with the use of high pressure compressed air. This process is called sand blasti

SEPPE cenospheres are a kind of hollow beads extracted from fly ash, accounting for about 1%~3% of the total amount of fly ash. Due to its unique formation conditions, it has multiple functions such as closed and smooth surface, thin and hollow wall, light weight, high strength, low thermal conducti

Bauxite is often used as raw material for high-alumina refractories and fused brown corundum. Bauxite used in refractories industry usually refers to bauxite with calcined Al2O3>=48% and low Fe2O3 content. The calcined bauxite has a fire resistance of 1780 ℃, strong chemical stability and good physi

Fire resistance is the property of the refractory material bauxite that can resist high temperatures during use without melting. Fire resistance is one of the important indicators for evaluating the quality of refractory materials. If the fire resistance is not high, during use, due to prolonged exp
