一、前言在钢梁制造中,对于板边缘的加工,锕桥制造规则中规定:经火焰切割的边缘,因产生渗碳和硬化层以及表面粗糙度过大等缺陷,因此必须经过机械刨边,以消除对疲劳与焊接的影响。对于钢梁制造而言,这些处理方法无疑是正确的。但是由于采用上述工艺,其机械加工量大,刨削浪费大量金属材料。因此不仅使钢 Preface In the manufacture of steel beams, for the processing of plate edges, the rules for the manufacture of actinide bridges stipulate that the flames cut by flame have defects such as carburized and hardened layers and excessive surface roughness and must therefore be mechanically edged , To eliminate the impact of fatigue and welding. For steel beam manufacturing, these treatments are undoubtedly correct. However, due to the use of the above process, its machining capacity, planing waste a lot of metal materials. So not only make steel
