一、前言随着工业炉窑节能工作的开展,越来越多的炉内水冷结构件被耐热结构件所代替。由于耐热结构件的材料费较高,所以设计时在保证其结构强度的同时应力求节约材料。但是它们大多数需要在高温状态下长期稳定工作,因此强度校核也就不同于普通结构件。二、耐热钢的强度众所周知,普通结构件的强度计算是以材料的屈服点σ_s或抗拉强度σ_b来确定的,耐热钢的生产厂家也往往以耐热钢在某个高温点所具有的抗拉强度σ_b做为该耐热钢的性能指标交给使用厂家。如果使用厂
I. Preface With the development of energy saving in industrial furnaces, more and more furnace water-cooled structural members are replaced by heat-resistant structural members. Due to the high cost of heat-resistant structural parts, so the design time to ensure its structural strength should also strive to save material. However, most of them require long-term and stable operation at high temperatures, so strength checking is different from ordinary structural parts. Second, the strength of heat-resistant steel As we all know, the strength of ordinary structural parts calculated yield point σ_s or tensile strength σ_b to determine the heat-resistant steel manufacturers often heat-resistant steel at a high temperature point has a Tensile strength σ_b as the performance index of the heat-resistant steel to the use of manufacturers. If you use the factory
