90% Al2O3 Corundum Castable Refractory Mortar for firebricks masonry

Catable Refractory mortar should be chosen with consideration of the close chemical composition of firebrick to ensure that the masonry can bond reliably. Also the mortar’s sintering temperature is or slightly lower than the parts of the working temperature so that the mortar can be sintered under operating conditions, and bond with refractory brick, but should not lower too much, so that the refractory performance can not adapt to the requirement of masonry.

Corundum Phosphate bond Refractory Mortar with features of:

1. Sufficient fire resistance,

2. Enough adhesive strength to combine masonry into a solid whole at the working temperature

3. Small dry shrinkage, no cracking at high temperature

4. Low apparent porosity and permeability, and good air tightness

5. Anti-slag corrosion

6. The thermal expansion coefficient is consistent with the firebrick, and different types of refractory mortars are selected for different masonry.

7, High temperature masonry performance

Corundum Phosphate bond Refractory Mortar is suitable for masonry high alumina fire bricks and andalusite fire bricks of hot blast stove and corundum fire bricks masonry.

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.
