一、前言马钢第三炼钢厂50t氧气顶吹转炉,配用70t钢水罐,原用二等轻烧高铝砖砌筑工作层。显然,这种传统工艺是存在着:机械化程度低、劳动强度大;罐内砌筑、劳动条件坏、不安全;砖型多、砖缝多、整体性差;抗钢、渣侵蚀性低等诸弊端的。该厂砌砖罐工作层为150mm,平均罐龄仅20次左右,耐火材料利用率不到50％,单耗高达9.06kg/t钢,成本3.14元/t钢。当用于吹氩、喷粉和 I. Introduction Maanshan Iron & Steel Third Steel Works 50t oxygen top blown converter, equipped with 70t steel water tank, the original second-class light-fired high-alumina brick masonry work layer. Obviously, there is such a traditional process: low mechanization, labor-intensive; tank masonry, bad working conditions, unsafe; many brick, brick and more, poor integrity; Disadvantages. The brick factory working layer is 150mm, the average tank age is only about 20 times, refractory utilization less than 50%, unit consumption up to 9.06kg / t steel, the cost of 3.14 yuan / t steel. When used to blow argon, dusting and
