It is widely used in the lining of the kiln working face which is in direct contact with the flame, and has become one of the research hotspots in recent years.
Mullite insulating brick for hot blast stove
Shaped lightweight heat-insulating refractory bricks are shaped block-shaped heat-insulating refractory products with a porous structure inside and thermal insulation properties. Among them, brick-shaped products are the most widely produced and used, so they are also called lightweight heat-insulating refractory bricks. Shaped mullite products mainly refer to mullite light insulation bricks, which are a new type of insulation material with Al2O3 content of 50%~80% and mullite (3Al2O3.2SiO2) as the main crystal phase and combined phase.

Because mullite light insulation brick has the following advantages:
High temperature strength
Good high temperature stability
Small coefficient of thermal expansion
Good thermal shock resistance and other advantages
It is widely used in the lining of the kiln working face which is in direct contact with the flame, and has become one of the research hotspots in recent years.
Insulating fire brick is a new type of building material synthesized with polymer materials. The main function is to keep warm, reduce heat loss and improve thermal efficiency.
GONGYI YUYING REFRACTORY CO.,LTD is located in GONGYI ZHENGZHOU CITY HENAN province,which is one of the main refractory production bases in China. Main products include different kinds of refractory brick and refractory material :Such as Fire Clay Brick, High Alumina Brick, Light Weight Insulating Brick,expanded clay,ceramic fiber blanket,rock wool products etc.They are widely used in Iron and steel, Nonferrous metals, BuildingMaterials(Cement,Glass,Ceramic), Petrochemical, Energy & Incineration etc industries.
low porosity clay bricks are mainly used in the regenerators of glass kilns. They can also be used in blast furnaces and hot blast furnaces in the steel industry; cement kilns in the building materials industry; chemical kilns in the chemical industry as kiln linings
Refractory castable is a kind of refractory material that does not need to be formed and has good fluidity after being fired and stirred with water.
The high-alumina refractory bricks sold by Yuying refractory manufacturers are commonly used refractory bricks with high thermal stability and refractoriness above 1770°C. It has good slag resistance and is used for the lining of steelmaking electric furnaces, glass melting furnaces, cement rotary furnaces, etc.
The unshaped refractory material used when repairing the lining of thermal equipment by spray construction method is called refractory gunning material. It is made of a refractory set with a certain particle gradation
Anhydrous taphole mud/taphole clay refers to taphole mud made of tar, resin, etc. as binders and corundum, bauxite, clay, silicon carbide, coke powder, etc. as raw materials. Anhydrous carbon taphole mud is made by a mud mill. When rolling, oil is added first, then block materials (clay and asphalt), and then powder materials (coke powder and clinker powder) are added after crushing. After pressing and mixing, the mud can be produced when it meets the standards.
Refractory carstables for ladles is made of high-purity fused corundum as the main material, high-purity spinel is added to the matrix, and an appropriate amount of binder and admixture (dispersant, water reducing agent) are added.
