Microstructure and Properties of Hot-rolled Seamless Steel Pipe
At present, domestic steel producers face enormous challenges seamless steel overcapacity, have to adjust product structure, eliminate backward production capacity and research and development of high-quality products. Experimental studies have shown: the implementation of control of the cooling process can be controlled phase transformation processes, grain refinement, thus improving the mechanical properties of hot-rolled seamless steel pipe production in the cooling process. Therefore, the study changes of microstructure and properties of steel under different cooling system after hot rolling seamless steel pipe to carry great significance and value. Because of seamless steel pipe having a larger cross-sectional dimensions and specifications outline the scope of the change, making it the control and implementation of online heat treatment faced by many variables, such that controlled cooling technology implementation and application in the production of seamless steel pipe has be...
