| Abstract: | The development of 80 mm thickness SX610CF heavy plate for hydropower in Nanyang Hanye Special Steel Co.,Ltd.was introduced.The chemical composition design and TMCP+ tempering process were mainly introduced,including the determination of heating temperature of slab,two stage controlled rolling process and the effect of different tempering temperatures on the microstructure and properties of the plate.The trial production results show that the slab heating temperature is set to 1 190-1 210 °C,and using the designed pressing procedure,the deformation of each pass can penetrate into the core of the plate,the core structure of the plate can be improved.Based on these,the mechanical propeties and impact toughness of plate can meet the technical requirements of hydropower steel. |
