Study On Accelerated Cooling Control System Of Seamless Steel Tube

Controlled cooling technology is a very important process during steel production. In order to make controlled cooling technology better apply in seamless steel tube field, accelerated cooling control system based on changeable roll table is discussed. Surface spiral temperature uneven distribution during cooling process is analyzed.By way of the background information of accelerated cooling control system study, the author introduced current development status of seamless steel tube, and analytical result of accelerated cooling simulation experiment. Main form of controlled cooling technology applied to seamless steel tube and implementation way of typical cooling control system are introduced based on current development status of cooling technology.The field condition, cooling principle, cooling mode, cooling equipment, and configuration of seamless steel tube cooling system are introduced. Based on the control system configuration and control request, the design of software, hardware and communications in the control system are introduced. Implementation way of main function of control system is particular explained.For uneven distributing of spiral temperature on the surface of steel tube during the accelerated cooling, effect of distribution of circumferential cooling ability of cooling device on tubes surface cooling equality was analyzed by the drawing, main cause of the spiral temperature uneven distribution was discovered.The accelerated cooling control system could meet the request of seamless steel tube cooling process by the application result. Comprehensive property of Steel tube is markedly improved after cooling. It may become effectual application way of controlled cooling technology of seamless steel tube.
