Background
After the continuous casting slab is produced, the surface quality needs to be checked, such as surface pits, longitudinal cracks, indentations, black lines and the like. These surface defects of the slab have an important influence on the quality of the subsequent rolled steel, and therefore, quality judgment is performed after the surface of the slab is inspected, and some surface defects are repaired. In the production process, the upper surface of the plate blank is easy to inspect, and the lower surface of the plate blank is difficult to inspect. Therefore, for the inspection of the lower surface of the key slab, the slab needs to be turned over by a slab turning machine.
The slab tilters currently used in iron and steel plants mostly install relatively large equipment on a roller way and adopt hydraulic drive. The main principle is that a large clamping device is adopted to clamp the plate blank, then the plate blank and the clamping device are turned over through a hydraulic driving device, and then the clamping device is loosened, so that the plate blank can run on a roller way. The slab turnover machine is suitable for turnover of large slabs, and needs huge equipment and hydraulic driving devices, so that the cost is high, and the operation and maintenance cost is also high. In the actual production process, not all slabs need to be turned, but only a small quantity of slabs with problems need to be turned, so the actual use frequency of the slab turning machine is not too high, but is indispensable. For a small plate blank production line, the hydraulic turnover machine has the problems of overhigh manufacturing, maintenance and operation cost, so that a special turnover machine is not generally used, most of the hydraulic turnover machine adopts a crane to temporarily turn over, the crane turns over time and labor, the turnover efficiency is too low, and meanwhile, the crane is occupied, so that the normal production is influenced, and the blank can be turned over only in idle time such as rolling line stop and rolling. In addition, a part of the plate blank is warped upwards and buckled downwards, and when the plate blank is conveyed to a heating furnace in a steel rolling workshop to be charged, because the plate blank is not straight, all supporting water pipes in the furnace are unevenly stressed after charging, and the water pipes are easily damaged and leak water. Therefore, the plate blank which is warped upwards and buckled downwards needs to be turned over and charged so as to ensure that the water pipe in the furnace is uniformly supported and stressed and avoid damaging the water pipe in the furnace.
