| Abstract: | By the means of analysis the reason of the hot rolled transport roller′s invalidation,and the reasonable welding materials-hard facing flux cored wire for submerged surfacing welding is choosed.The successful remediation of SF55 hot continuous rolling roller conveyer roller of baosteel stainless steel branch hot rolled factory is described,and the hard facing remediation process is also introduced in the article,the practice of production indicates the working life of the repaired transport rollers are 1.5~2 times of the wording life of the new ones,the expenses are 30%~35% of the new ones.Its economic efficiency has greatly improved. |
