Method for solving 09CuPCrNi-A weathering steel defect

In order to avoid the occurrence of weathering steel profile blanks, it should be produced by molten steel light calcium treatment + sizing nozzle casting.The surface longitudinal cracks and joints of 09CuPCrNi-Aweathering steel were seriously affected by the quality of the product.The causes of the product were analyzed. The corresponding improvement measures were proposed, including optimizing the chemical composition of the steel and adjusting the speed. Heat, profile cooling process parameters, casting method, etc., the quality of the profiled blank is greatly improved, meeting the needs of 09CuPCrNi-A weathering H-beam production.
