Development and Application of Roller Quenching Process for XGCF62 Plate

Based on domestic plate roller quenching equipment and technology,the theoretical calculation and the industrial experiment were used to develop the quenching process and the product of high-quality pressure vessel plates XGCF62.Using finite difference method,the calculation model of plate quenching temperature field was established to analyze the trend of internal temperature with different quenching parameters.Compared with industrial experiment,the effects of different quenching parameters on microstructure and mechanical properties were analyzed.The calculated and experimental results were applied to actual production and a series of 6～60 mm thickness XGCF62 products with good flatness and mechanical properties were successful developed.
