External Refining High Alumina Castable Refractory High Refractoriness Good Stability

High alumina castable for external refining high refractoriness good stability

Working conditions of high alumina castable refractory for external refining:

1. Long time high temperature and vacuum effect

2. Severe erosion of slag

3. Soaking effect of slag

4. Strong scouring and wear of slag and molten steel

5. Thermal shock due to temperature abrupt change

6. Local overheating and arc radiation

Characteristics of refractory high alumina castables for refining outside the furnace:

1. High refractoriness, good stability, and resistance to high temperature and vacuum conditions under out-of-furnace refining conditions

2. Low porosity, high bulk density, compact organization to reduce slag penetration

3. High strength, wear resistance, resistance to erosion and wear of steel slag

4. Good corrosion resistance to acid and alkali slag erosion

5. Good thermal stability, no thermal shock cracking and spalling

6. Non-polluting molten steel, conducive to the purification of molten steel

7. Less environmental pollution

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!
