Problems solved by technology

[0002] In the heat treatment production of cold-rolled strip steel, when encountering problems such as welding, strip deviation in the furnace, and HMI crash, the production line speed and strip temperature need to change rapidly. The continuous annealing furnace is a large inertial lag and multi-variable Complex working condition system, if the above emergencies are encountered: ① It will cause the speed of the strip steel in the furnace to be unable to be monitored
② Too slow adjustment will cause hot or cold warping of the strip steel in the heating section or fast cooling section, resulting in a large amount of waste products
③The tension adjustment is not timely, the strip steel is seriously bent, and the tension in the furnace changes too much, causing the broken belt in the furnace to stop

Abstract

The invention discloses an emergency state control system of a continuous annealing furnace on a continuous assembly line. The emergency state control system comprises a speed control module, a tension control module, a heating section control module and a rapid cooling section control module. The speed control module is used for setting and rapidly adjusting operation speed of a furnace area of the continuous annealing furnace; the tension control module is used for rapidly adjusting a tension value of the furnace area of the continuous annealing furnace; the heating section control module is used for rapidly converting the furnace area of the continuous annealing furnace from a heating mode into a furnace standby mode; and the rapid cooling section control module is used for setting rapid cooling section blower speed and rapidly converting the blower speed into speed with a set value. The emergency state control system of the continuous annealing furnace on the continuous assembly line, disclosed by the invention, mainly solves a strip steel control problem in the furnace at an emergency state of the annealing furnace through the integration of the control system. The emergency state control system of the continuous annealing furnace on the continuous assembly line, disclosed by the invention, has the advantages of being short in operation time and simple in operation. Furthermore, the labor intensity of operators can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of cold-rolled strip rolling control, in particular to an emergency state control system for a continuous annealing furnace on a continuous production line. Background technique [0002] In the heat treatment production of cold-rolled strip steel, when encountering problems such as welding, strip deviation in the furnace, and HMI crash, the production line speed and strip temperature need to change rapidly. The continuous annealing furnace is a large inertial lag and multi-variable In complex working condition systems, if the above emergencies are encountered: ① It will cause the speed of the steel strip in the furnace to be unable to be monitored. ②If the adjustment is too slow, the strip steel will produce hot or cold warpage in the heating section or fast cooling section, resulting in a large amount of waste products. ③The tension adjustment is not timely, the strip steel is seriously bent, and the tensi...
