摘　　要：石钢推钢式加热炉用传统耐火砖砌筑的拱形墙极易变形,甚至发生整体坍塌的事故,给生产造成了不利影响。分析了炉尾拱墙坍塌的原因,用模块化的设计思路对拱墙进行整体分解,分别设计了各部分用砖的形状和尺寸,采用自行设计的异型砖砌筑的拱墙强度和承载力都得到了很大提高,延长了拱墙的使用寿命,保证了加热炉的正常生产。The arc wall at the tail of the pusher heating furnace of Shi Steel is built with normal refractory bricks and easy to be deformed, even collapse as a whole, and so always affect the production. It is analyzed the reason for collapse, decomposed the arc wall with modular design idea, separately designed the different shapes and sizes of bricks for various part of arc wall. Constructed with those self - designed complicated shape bricks, the arc wall is got greatly improved in strength and bearing capacity, its working life pro- longed, the regular production of heating furnace guaranteed.
