Mullite Kiln Insulation Materials / Shock Resistant Perlite Insulation Concrete

Mullite Castable refractory for Cement kiln Dense thermal shock resistant 2.45g/cm3

Mullite castable refractory for cement kiln uses high-quality mullite as main raw material, added to cement, silica powder, wear-resisting material, and other auxiliary materials. Al2O3 content is more than 65%, The main impurity of high strength mullite castable refractory used in cement kiln is iron oxide, the content of iron oxide is controlled within a certain range (less than 1. 5%), which is good for the product stability, improving the using performance.

Mullite castable refractory features:

1, Good thermal shock resistance, this is an outstanding advantage of high strength mullite castable that make good use effect. Thermal shock resistant at 1100℃ water cooling, can reach more than 25 times.

2, High cold crushing strength

3, Good resistance to erosion

4, Volume stability and high service temperature.

Mullite refractory castable application

As for its outstanding using effect, it is the best and the most ideal castable for new dry process cement kiln. And it’s widely used in cement kiln decomposition furnace, tertiary air duct and any other parts.

Jundao (Henan) New Materials Co.,Ltd（For short: JDNRCO） was registered in April 2006 at Yuecun Town，Xinmi City, Henan Province of People’s Republic of China, one of the key enterprises in refractory materials in China. Using refractoriness as the main raw material, JDNRCO produces fireclay、high-Al、corundum、mullite series of high load、low creep、high density、low porosity refractory bricks, series of light weight insulation、high crushing strength、acid and alkali resistant refractory materials. The products are mainly used in Non-ferrous metal industry, Steel industry, Metallurgical industry, Building industry, Power industry and other industries….

The company purchased a large number of advanced and international testing equipment to research new materials and test products quality, which promoted all of product to meet the design requirements. After having designed and built the gas tunnel kiln with environmental friendly and fully automatic controlled high temperature, JDNRCO got a comprehensive annual output of 70,000 tons of high quality refractory capacity, and had been assessed as conforming to meet the requirements of GB/T19001-2016/ISO 9001：2015, which promoted the sustainable development of company.

There is one professional technical team, the main managers in different divisions of the company are all have the corresponding senior or middle professional titles.
