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.
Yuying Refractory produces a complete set of refractories for electrolyzers, and the new impermeable bricks are used in conjunction with impermeable castables
Special Acid-proof Brick Lightweight acid-proof Brick Acid resistant brick is the ideal choose for your project with their features of proof pressure, corrosion resistance, easy to clean and acid-base resistance.
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.
Chrome corundum brick refers to corundum refractory products containing Cr2O3. At high temperature, Cr2O3 and Al2O3 form a continuous solid solution, so the high temperature performance of chromium corundum products is better than that of pure corundum products. Chromium corundum products are widely used, and the content of Cr2O3 is mostly in the range of 9% to 15%.
The alumina ball is also called the high aluminum accumulation of heat ball.High alumina refractory ball is based on bauxite as the mainly raw refractory material.Adding powder and additives and anchoring agent.After proportioning, molding and high sintering to make it.The production engineering of high alumina refractory ball is similar to that of high alumina refractory brick.It should be based on the properties of raw materials,high alumina refractory ball requires production conditions and other factors to determine.
High alumina brick is mainly used for lining of blast furnace, hot blast furnace, electric furnace roof, reverberatory furnace and rotary kiln. In addition, high alumina brick also widely used as open hearth regenerative lattice brick, pouring system with plug,such as nozzle brick.
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.
