An electrical control system for a decarbonization production line

Abstract

The invention discloses a decarburization production line electrical control system comprising a PLC programmable controller, a human-computer interface, multiple uncoiling consoles and multiple transmission devices. The human-computer interface is electrically connected with the PLC programmable controller. The uncoiling consoles and the transmission devices are connected with the PLC programmable controller in a communication way through a PROFIBUS. When the system is used, the parameters of the control system are set by using the human-computer interface, and the concrete steps are listed as follows: 1) hearth roll basic speed is set, the hearth roll is divided into a coiling section, a process section and an uncoiling section, and the inching speed of the coiling section, the process section and the uncoiling section of the hearth roll is set; 2) the unit tension sensor data are set, and the tension inspection channel is from the uncoiling section; 3) coiling and uncoiling reel automatic control is set, and the interval time and the action time are set; 4) the basic parameters of the hearth roll are set; and 5) the basic parameters of the motor are set. The decarburization production line electrical control system is stable in production process and high in environmental adaptability.

Description

technical field [0001] The invention relates to an electric control system of a decarbonization production line. Background technique [0002] Decarburization is a phenomenon in which the carbon content on the surface of steel decreases when it is heated. The process of decarburization is that carbon in steel reacts with hydrogen or oxygen at high temperature to form methane or carbon monoxide. There are three main methods: (1) The physical absorption method is the first to use pressurized water to remove carbon dioxide, and regenerate the water after decompression. The equipment of this method is simple, but the degree of purification of carbon dioxide removal is poor, the outlet carbon dioxide is generally below 2% (volume), and the power consumption is also high. In the past 20 years, methanol washing method, propylene carbonate method, polyethylene glycol dimethyl ether method, etc. have been developed. Compared with the pressurized water decarburization method, they h...
