Light Weight Refractory Insulation Materials High Temperature Performance

Light weight Mullite Refractory insulation castable high temperature performance for

kiln lining

Light weight Mullite castable takes high quality porous mullite aggregate as raw material, plus a fine powder and additives that used in heating furnace. As the product takes high grade synthetic materials and combines with low cement or micro powder and used in high temp parts, so should select excellent pure calcium aluminate cement and its general control in 5%-10%, too much will reduce the product high temperature strength and anti-spalling strength.

Light weight Mullite castable has good high temperature performance, the service temperature is 1350℃ which can contact flame directly as furnace lining. As its little volume density and low thermal conductivity, the product has excellent thermal insulation performance. Also it has high mechanical strength, good thermal shock resistance and good abrasion resistance. Construction rapidly which can shorten the oven time to get significant economic benefits.

Light weight Mullite castable is mainly used for boiler, blast furnace, hot blast stove, heating furnace, ceramic furnace and other furnace lining.

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.
