High Tensile Strength Tap Hole Clay Stemming For Smelting Electric Arc Furnace

Tap-hole clay stemming for smelting electric arc furnace

Tap-hole mix for smelting electric arc furnace is mainly used in the taphole of large-scale smelting electric arc furnace. Tap-hole mix for smelting electric arc furnace by our company has good combination, it can maintain the muzzle without deformation under normal conditions of use, and has the characteristic of easy to open.

The key technology of the project products:

The high-tech products with material composition, particle grading distribution and comprehensive properties were developed by selecting varieties of suitable raw materials for scientific matching through a large number of experiments.

Through a large number of tests, several kinds of single or composite type non-polluting binders were selected to avoid generating flue gas with hazardous materials in the use of tap-hole mix and improve the working environment.

The tap-hole mix for smelting electric arc furnace developed has the advantages of less pollution, easy blocking, and erosion resistance.

Advantages of tap-hole mix for smelting electric arc furnace:

1. The tensile strength is high, and it is of great significance to maintain the stability of the blast furnace condition (tapping depth, tapping time fluctuation, total air blocking rate, etc.), so that the blast furnace has the basis for increasing production.

2. Strong slag resistance. The tap-hole mix consumption is low, generally one-fifth of the hydrous tap-hole mix.

3. It has certain expansion performance.

4. With suitable porosity and strength, it can adapt to the use of large blast furnaces over 2000m.

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.
