[0042] The temperature control unit includes a temper...

Embodiment 2

[0055] The basic structure of the intelligent control system of a tubular continuous annealing furnace in this embodiment is the same as in embodiment 1, the difference is that the tension monitoring unit is replaced by a tension monitoring unit in the intelligent control system of a tubular continuous annealing furnace in this embodiment It is a torque motor controlled by a computer, which can be used as a take-up reel drive motor to take up the wire with a constant torque, thereby ensuring a constant tension of the wire and simplifying the structure of the system. The speed information of the torque motor is fed back to the cable control module by the single-chip microcomputer control board to ensure that the cable control module is adjusted synchronously. In addition, the parameter input and display modules in the intelligent control system of a tubular continuous annealing furnace in this embodiment are replaced by a computer. The single-chip microcomputer control board and...

Abstract

The invention discloses a system and method for intelligently controlling tube continuous annealing furnaces, belonging to the technical field of intelligent control. The system disclosed by the invention is formed through carrying out a technical improvement on an existing annealing device, and respectively carries out intelligent control on an auxiliary push roller drive motor, a guide roller drive motor, a take-up reel drive motor and a winding displacement control module; a temperature sensor is respectively added on an annealing furnace and a drying furnace so as to intelligently control the annealing and drying temperatures; and the control processes are all implemented by parameter input, a display module or a computer, thereby achieving the purpose of remote monitoring and control. According to the invention, a situation that wires run in zero tension in the annealing furnace can be ensured, thereby avoiding that the wires are stretched after being softened by heating; the wires subjected to annealing can achieve an effect of constant-tension take-up, and the temperature control precision of the drying furnace and the annealing furnace is high, therefore, a situation that the wires running in the furnaces are always in an optimal recrystallization state is ensured, and the energy-saving effect is good; and the system and method disclosed by the invention are high in degree of automation, and realize remote monitoring and intelligent control.

Description

technical field [0001] The present invention relates to an intelligent control system and method, more specifically, to an intelligent control system and method for a tubular continuous annealing furnace.
