Resin Bonded Tap Hole Clay Stemming Good Plasticity For Medium Sized Blast Furnaces

Resin-bonded tap-hole clay stemming

The resin used in the resin-bonded tap-hole clay is liquid phenolic resin. The average molecular weight of the phenolic resin has a significant effect on the hardening speed of the gun mud. Generally, the hardening speed accelerates with the increase of the average relative molecular mass, and the hardening speed too fast will affect the working performance of the taphole mix.

Resin-bonded tap-hole mix is generally used in large and medium-sized blast furnaces. It is made of fused corundum (brown fused alumina), silicon carbide, graphite, soft clay, asphalt, coke powder and additives (including silicon nitride or ferrosilicon nitride).

The application effect of resin bonded taphole mix is better, which not only improves the working environment, but also shortens the working time, ensures the depth of tapping hole and stable tapping operation.

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.
