1前言早在20世纪80年代就对通过高炉风口喷吹粉矿进行了研究,以作为有前途的下一代高炉新技术。当时的研究只是小量喷吹,每吨生铁喷吹大约50 kg粉矿,是作为降低铁水中硅含量的一种措施,但随着较高生产率和改善生产灵活性的要求越来越强烈,要求将喷矿量提高到100 kg/t或以上。新
1 Preface As early as the 1980s, the study of blast furnace tuyere injection was carried out as a promising new technology for the next generation of blast furnaces. At that time, the study was only a small amount of injection. Injection of about 50 kg of fines per ton of pig iron was used as a measure to reduce the silicon content in the hot metal. However, with the demand for higher productivity and improved production flexibility, Requires the amount of sprayed ore to be increased to 100 kg / t or above. new
