Blast Furnace Castable Refractory Material For Hot Air Duct Strong Impact Resistance

High alumina refractory castable for blast furnace hot air duct strong impact resistance

The hot air duct is a variety of tuyere devices that transport hot air from the hot air stove to the blast furnace.The hot air duct lining structure is usually composed of a refractory sprayed layer, refractory fiber, lightweight insulating refractory bricks and tough mullite bricks in working layer. The gas supply pipe is cast by castable. The mullite bricks in the pipeline generally adopt circular joints and have different masonry methods. The hot air in the hot air duct is distributed in the blast furnace, so the hot air duct plays an important role in the blast furnace.

The high alumina castable for hot air duct is made of high-strength cement, mineral admixture, high-strength aggregate and anti-cracking agent through industrial production.

It has high wear resistance, high bonding strength with foundation concrete, strong impact resistance, high compressive strength , long service life and so on.

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.
