Light Weight Refractory Insulation Materials For Industrial Kilns 1.1~1.5g/Cm3

1.1~1.5g/cm3 Light weight Alumina Bubble Refractory Insulation material

for Industrial kilns

Alumina bubble is a new kind of high temperature refactory insulation material. Bases on alumina bubble as the main body, it can be made into various shapes, the highest operating temperature 1800 ℃, the product with high mechanical strength that is general light products several times, and the bulk density is only half of the corundum products.

Alumina bubble Refractory Insulation brick uses alumina bubble and alumina powder as the main raw material, combined with other binder, through 1750 degrees high temperature firing which is a kind of ultra-high temperature energy-saving insulation materials.Alumina bubble refractory insualtion brick can be used for high temperature kilns such as shuttle kiln.

Alumina bubble Refractory Insulation brick Features:

1. High operating temperature: It can reach over 1750 degrees, with good thermal shock resistance, small reheat linear change and durability.

2, Lightweight: Commonly used refractory materials belong to heavy bricks with volume density generally 2.6-3.0 g/cm3, alumina bubble brick only 1.1-1.5 g/cm3, thus reducing 1.1-1.9 tons per volume.

3, Energy saving: Alumina bubble has obvious thermal insulation properties, low thermal conductivity which have very good heat preservation effect, and can reduce the heat dissipation, increase thermal efficiency, thereby achieve the purpose of saving energy. The energy saving effect can reach more than 30%.

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. They have professional ability to communicate with customers timely and can handle with customers’ demands effectively. Also there are specialists who are responsible for the customers’ after-sales work.

Nowadays, JDNRCO has long-term cooperation with large state-owned enterprises, such as Chalieco, NFC, Sinosteel etc. In addition, JDNRCO actively develops the international market, and has exported to Southeast Asia, the Middle East and other foreign countries’ large-scale projects, such as Indian Bharat Alumina Co.,Ltd, Iran Alumina company etc, which has improved the corporate reputation.

Jundao (Henan) New Materials Co.,Ltd welcome customers from all over the world come for business cooperation!
