Embodiment Construction

[0067] see figure 2 , figure 2 It is a schematic diagram of the timing relationship between the control signals in the control method of the equipment for establishing tension according to the present invention, and there are differences according to the operation mode (a complete group operation or a single jog operation), and the specific description is as follows:

[0068] The preferred control method of the present invention to the equipment that establishes tension in a complete group operation is:

[0069] The speed control "enable" and the brake opening signal 1 are turned on simultaneously with the group operation command being turned on, and it is turned off with a delay of 1050ms after the group operation command is turned off and the main command speed drops to zero;

[0070] The operation "enable" signal 2 is turned on simultaneously with the group operation command being turned on, and it is turned off with a delay of 2220ms after the group operation command is...

Abstract

The present invention discloses a method for using a coordination control module to control a strip steel continuously producing machine set. The method respectively provides the control method for every type of equipment under every operating mode according to the sorts of the controlled equipments including tension establishing equipment, speed reference equipment or auxiliary equipment and according to the differences of the operating modes of one time complete set operation or independent inching operation and especially provides the time sequence relation of every control signal. The method can improve the working characteristic of the whole producing machine set and the dynamic response performance of the machine operation and can ensure the accordance of the equipment and the strip steel surface line speed during the starting and the stopping periods, and avoids surface scuffing of the strip steel. The method is realized on the basis of a delay engage relay by software, only ordinary instruction is used, and the control logic can be realized in various kinds of PLC conveniently.

Description

technical field [0001] The invention relates to a method for controlling a strip steel continuous production unit by utilizing a coordinated control module. Background technique [0002] In metallurgical plants, there are widespread situations that require multiple equipment to operate synchronously, such as cold tandem rolling mill and its cold rolling treatment unit, continuous annealing unit, hot-dip galvanizing unit, electro-galvanizing unit, electro-tinning unit, etc. Multiple devices in the unit are connected by strip steel to work together. see figure 1 , figure 1 It is a schematic diagram of common rolling mill entrance equipment. These equipment can be divided into three categories. The first category is equipment that establishes tension, such as uncoilers. Its characteristics are: when the strip is not connected with other equipment, it is controlled by speed. When the strip is connected with other equipment , which is controlled in tension. In order to make ...
