Φ720mm Seamless Steel Pipe Industrial Furnace Automation Control And Monitoring

China’s large-diameter seamless development year-on-year foreign researchproduction lagging behind for a long time, since2008, China voted to build a set of720seamless steel pipe production line, fill the blank of China’s large diameter seamlesssteel pipe industry. The goal of this study industrial furnace heating billets formallyadded to the tube on the basis of the blank tube heating process automated control andmonitoring of industrial furnace applications.Research by stepping industrial furnace in a factory in New Φ720seamless steelpipe production line as the platform. Mainly through the combustion system, as well asthe stepper system to control the blank tube (259mm-457mm) was heated to1200°Cthe control of from20℃reached parison tube pipe expansion required temperature, toprepare for the next step Flaring Major operating systems: Siemens Simatic S7-400System.Control system of PLC the installed Ethernet module with the host computernetworking; PLC to Industrial Ethernet with the host computer for data communication.Two upper machine independent, working at the same time, in order to ensure fullredundancy of the HMI.The above system including transmission and combustion system as a system. Acomputer and monitor UPS power supply, to ensure that even in the case of loss ofpower the main power supply, but also be able to monitor the condition of the entirestove.Equipped with a network card, the host computer for data communication usingTCP/IP protocol and the two control systems.Stepping through this set of industrial automation control and monitoring furnacesdesigned to meet the next process rotary Flaring extent the blank tube heating, theheating time of the demand, while the industrial furnace equipment operating conditionsand furnace control start and stop controls especially critical role to play.Industrial control automation technology is the development of intelligent,networked and integrated direction. This article by reheating furnace design automationcontrol and monitoring, to reach the fully continuous, fully automated, automaticmonitoring. Improve production the rhythm and product quality control, and enhance the international competitiveness of products. Immediately following the direction ofthe development of automation technology today.
