高炉用耐火制品
高炉用耐火材料是我公司最早的优势产品，有四十多年的生产历史，高炉用粘土砖曾与1983年和1988年两获国家银质奖，这也是我国耐火材料界的最高荣誉；我公司是粘土质高炉砖国家标准的第一起草单位。随着我国钢铁工业的发展，我公司又相继开发了系列低气孔粘土制品、刚玉莫来石制品、碳复合制品、铝-碳化硅制品。
Refractory bricks for Blas Furnace are our traditional super products with experience of 40 years.Fireclay blast furnace bricks go on awarded national silver medal in 1983 and 1988,which is still the highest honor in Refractory industry.National standard of Fireclay Blast Furnace bricks were first drafted by Lunai.Following the development of Iron & Steel industry,we also are in reaching and producing series of low porosity Fireclay products,Corundum-Mullite products,Carbon containing products and Alumina-SiC products.
