China's widest bar heating furnace was completed and put into production! During the construction of the heating furnace, the technical experts of Shiheng Special Steel and the technical experts of MCC Southern Thermal Engineering Co., Ltd. demonstrated and designed the bar heating furnace with the widest furnace width, the longest billet and the largest output in China. The heating furnace adopts a number of green and intelligent technologies: the wave-shaped roof design is adopted to strengthen the radiation heat exchange in the furnace and improve the heating efficiency.
The effect of alloy elements on the properties of heat treatment methods for thick steel plate: the performance of heat treatment method reflects the difficulty coefficient level of heat treatment process and the tendency of defects caused by heat treatment process. The key points include cutting performance, over temperature sensitivity, quenching aging tendency and air oxidation carburizing tendency. A709 Gr 50 low alloy steel sheet, Carbon steel has high machinability, and slow cooling method can be used in heat treatment, which can reduce the deformation and cracking tendency of the products. The addition of Mn and Si will increase the over temperature sensitivity of steel.
