Welding method for vertically spliced super-thick steel plate
ActiveCN102861972AControl welding deformationReduce turning timesWelding/cutting auxillary devicesArc welding apparatusSheet steelTurnover time
A welding method for a vertically spliced super-thick steel plate is a welding method for a super-thick steel plate with the thickness ranging from 60mm to 120mm. The method is characterized by including: hoisting a primarily spliced super-thick steel plate onto a special jig frame for horizontal welding, fixing the super-thick steel plate with a waler of the jig frame by welding prior to fastening the super-thick steel plate with a ground abutting floor stand by the aid of a wedge, then using carbon dioxide arc welding for sequential symmetry horizontal welding on the front side and the back side of the super-thick steel plate respectively by even welders until spliced plate welding is finished, and finally performing postheat treatment to prevent cracks. The method has the advantages that welding deformation of the spliced super-thick steel plate can be well controlled, welding deformation correction is avoided, welding cracks are prevented, welding quality is improved, and construction requirements are met. The carbon arc air gouging process for back gouging is omitted, welding procedure is simplified, turnover times of the super-thick steel plate are decreased, workload is reduced, labor intensity is relieved, and production efficiency is improved.

A hot-rolled section steel roll, with the material of brand SGA1 as the outer layer and the material of brand QT500‑5 as the core material. After heat treatment, the metallographic composition of the outer layer changes, such as: at a depth of 0mm from the surface, by 30% ~35% carbide, 5%~7% graphite, and matrix with lamellar structure pearlite, transformed into 15%~18% carbide, 6%~8% graphite, and fine granular pearlite and acicular structure the matrix. The hot-rolled profiled steel roll provided by the invention is produced by a centrifugal composite bimetallic casting method, which not only greatly increases the alloy content of the outer layer of the roll, but also further improves the wear resistance and thermal crack resistance of the product. After actual rolling, the amount of passing steel has increased by more than 30%, and there is no phenomenon of ring collapse or roll breakage. Reduce the direct cost of roll consumption by more than 30% for iron and steel enterprises.
