最近,英国Hepworth耐火材料公司开发出一种高炉用耐火材料制品Carbel BF,即Sialon结合碳化硅砖。该产品旨在满足现代化的、高生产率的高炉炉身下部、炉腰、炉腹和风口区用砖的要求,在精心砌筑和与良好设计的水冷系统配合下,可大大延长高炉寿命。其特点如下: 1)该砖在严格控制气氛的窑内烧成,其成分均一,物理、机械和热性能俱佳; 2)碳化硅含量高,加之气孔率低、密度高,使该产品的耐碱腐蚀性能大大提高; 3)组织致密,常温耐压强度大,耐机械
Recently, Hepworth Refractories UK has developed Carbel BF, a refractory product for blast furnaces, that is, Sialon bonded silicon carbide bricks. The product is designed to meet the requirements of modern, high-productivity blast furnace heaves, furnace spits, bosh and tuyere bricks, and with the exception of masonry and well-designed water cooling systems, the blast furnace life can be greatly extended. Its characteristics are as follows: 1) The brick is fired in a controlled atmosphere kiln with uniform composition, excellent physical, mechanical and thermal properties; 2) high silicon carbide content, combined with low porosity and high density, Alkali corrosion greatly improved performance; 3) dense structure, at room temperature compressive strength, resistance to mechanical
