Hellow Ball Insulating Fire Proof Brick , Lining Refractory Material White Al2O3

Al2O3 Hellow ball Insulating Fire Proof brick uses fused corundum, sintered alumina and industrial alumina as the main raw materials, made of heat-resistant refractory products, with acid and alkali resistant and strong anti-reduction ability, good thermal shock resistance characteristics.

l2O3 Hellow ball Insulating Fire Proof brick can be used under 1700°C for a long time. Its production process adopts the foam method and the burn-in addition method. Two kinds of foam methods are: using rosin soap foam agent and finely pulverized raw materials, binding agents, etc. to prepare foam mud, casting molding, drying, firing, shaping, and selection.Al2O3 Hellow ball Insulating Fire Proof brick produced by the foam method are characterized by uniform structure, low thermal conductivity, and good thermal insulation properties.

Al2O3 Hellow ball Insulating Fire Proof brick is light weight with high compressive strength, low thermal conductivity, little pemernent linear change, and good thermal shock resistance.

Al2O3 Hellow ball Insulating Fire Proof brick can be used in the heat insulation layer of high-temperature thermal equipment or in furnaces directly affected by flames. The work of precision thermal equipment is lining, but it is not suitable for direct contact with the erosion of molten liquid and molten slag. The working temperature depending on the product purity is generally up to 1650 ~ 1800 °C.

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!
