Embodiment Construction

[0022] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] The control device for the pressure alarm of the continuous annealing furnace of the present invention mainly includes three modules, that is, a pressure switch low pressure alarm module, a voting module and an arbitration module. Utilizing these three modules, it can be seen that the control method of the continuous annealing furnace pressure alarm of the present invention does not directly cut off the operation of the entire furnace section when the gas pipeline pressure is low and alarms, but determines whether the multiple peripheral parameter values ​​are normal, according to The importance is assigned weights and voted uniformly, and the final judgment is made by the arbitration module. If the arbitration module believes that the advantages are greater than the disadvantages according to the voting results, the fu...

Abstract

The invention discloses a control device of continuous annealing furnace pressure alarming and a method thereof. The control device comprises a pressure switch low-pressure alarming module, a voting module and an arbitrating module. The pressure switch low-pressure alarming module triggers the voting module. The voting module samples a plurality of system states, allocates the corresponding voting values according to the system states, and sends the voting values to the arbitrating module. The voting values are respectively multiplied by weight through the arbitrating module, the voting values multiplied by the weight are added to obtain the arbitrating result, and the arbitrating result controls a furnace to continue to operate or to stop. By means of the technical scheme, when a pressure switch gives an alarm at the low pressure, the operation is not easily and directly cut off after the delay is carried out but a system parameter is judged for further controlling the operation or the non-operation of the annealing furnace according to the judgment result so that the annealing furnace can still keep working when small fluctuation is produced, normal operation of the annealing furnace is not easily interrupted, and the yield, product performance and unobstructed logistics can be guaranteed.

Description

technical field [0001] The invention relates to the field of smelting equipment, more specifically, to a control device and method for a continuous annealing furnace pressure alarm. Background technique [0002] The continuous annealing horizontal furnace is a relatively common heating furnace. The furnace is divided into several zones along the direction of strip steel travel, and the furnace temperature is controlled by zone. The accuracy of furnace temperature measurement seriously affects the quality and performance of products. For product performance, the accuracy of furnace temperature is very important. The decrease of furnace temperature accuracy will directly lead to unqualified product performance. The temperature in the furnace is maintained by providing heat through the burner, and the burner is ignited after mixing gas and air to provide heat for the furnace to maintain the stability of the furnace temperature. Therefore, the gas supply pressure of the burner ...
