ABOUT XINYUAN

Ceramic fiber textiles include ceramic fiber yarn, ceramic fiber cloth, ceramic fiber belt, ceramic fiber rope and other products. They are made of ceramic fiber cotton, alkali-free glass filament or high-temperature resistant stainless steel alloy wire through special processing. In addition to the above products, we also provide high-temperature resistant textiles with special specifications and performances according to the user's requirements on the use temperature and specific use conditions.

Grade I High Alumina Bricks is a neutral refractory material with an alumina content of not less than 75%. It is formed and calcined from alumina or other raw materials with high alumina content. It has high thermal stability and refractoriness above 1770℃. It has good slag resistance and is mainly used for lining blast furnaces, hot blast furnaces, electric furnace tops, blast furnaces, reverberatory furnaces and rotary kilns. In addition, high alumina bricks are also widely used as open-hearth regenerative checker bricks, plugs for pouring systems, nozzle bricks, etc.

Silica Mullite Brick are made of high-aluminum bauxite clinker and silicon carbide as the main raw materials, and are formed by high-pressure molding and high-temperature firing. It has normal temperature compressive strength and high temperature structural strength, good thermal shock stability, and continuously forms a protective layer during use. Good wear resistance and strong peel resistance. Suitable for transition zone, cooling zone, kiln mouth and other locations.

Magnesia carbon bricks are made of high-melting-point alkaline oxide magnesium oxide (melting point 2800℃) and high-melting-point carbon materials that are difficult to be wetted by slag as raw materials, and various non-oxide additives are added. It is a non-burning carbon composite refractory material combined with a carbon binder. Magnesia carbon bricks are mainly used for the lining of converters, AC arc furnaces, DC arc furnaces, slag lines of ladles and other parts.

Clay refractory bricks refer to clay products with an Al2O3 content of 30% to 40% aluminum silicate material.

Silicon nitride bonded silicon carbide brick refers to a refractory product made of SiC and Si as raw materials and nitrided. 

The mineral composition of silica bricks is mainly tridymite and cristobalite, with a small amount of quartz and glass. Tridymite, cristobalite and residual quartz have a large change in volume due to crystal form changes at low temperatures, so the thermal stability of silica bricks at low temperatures is very poor. During use, it should be heated and cooled slowly below 800℃ to avoid cracks. Therefore, it is not suitable for use in kilns with rapid temperature changes below 800℃. It is mainly used for the partition walls of the carbonization chamber and combustion chamber of the coke oven, the regenerator and slag chamber of the steelmaking open hearth, the soaking furnace, the refractory materials of the glass melting furnace and the ceramic firing kiln, etc. The vault and other load-bearing parts of the kiln. It is also used for the high-temperature load-bearing parts of the hot blast furnace and the top of the acid open hearth furnace.
