Embodiment Construction

[0010] At present, the R0 reduction control of TISCO 1549 hot continuous rolling rough rolling only has three modes: automatic, manual and OFF under the C mode (that is, the process automatic control mode, all basic automation and process automation functions are in the activated mode). The automatic mode is adopted during the steel rolling process; the manual pressing mode is adopted during the process of stopping the roll change and manual zero adjustment; the OFF mode is the mode selected when the stop pressing does not act. Regardless of whether it is in automatic or manual mode, it adopts double closed-loop control of position and speed. All interlock conditions of RUN1, RUN2, RUN3, FAULT1, FAULT2, and FAULT3 in the program are met (EGC position sensor hardware failure, pressure head failure, depression communication failure, transmission system failure, thin oil lubrication conditions are not ready, Position sensor synchronization failure, EGC rectification unit operatio...

Abstract

The invention relates to the field of hot continuous rolling rough rolling, and discloses an O mode operation method for hot continuous rolling rough rolling R0 reduction control. The method comprisesthe following steps that an O operation mode option is added to a main interface of the hot continuous rolling rough rolling R0 reduction control; the state of the hot continuous rolling rough rolling R0 reduction control is displayed as a green automatic control state; during overhaul or rolling line fault, a C mode is switched into an O mode by an operator for the hot continuous rolling rough rolling R0 reduction control, at the moment, the red O mode is displayed on the main interface of the hot continuous rolling rough rolling R0 reduction control, and the state of hot continuous rollingrough rolling R0 reduction control is displayed as a red fault state; and after the operation mode is switched into the O mode by the operator, a speed controller is directly started through a controlprogram. The method has the beneficial effects that O-mode control over rough rolling reduction motor overhaul is achieved, and the problem that the overhaul time is too long due to the fact that aninterlocking link is forced in the overhaul process is solved.

Description

technical field [0001] The invention relates to the field of hot continuous rolling and rough rolling. Background technique [0002] Taiyuan Iron and Steel Co., Ltd. 1549 hot continuous rolling rough rolling R0 reduction control is to realize the adjustment of the reduction roll gap by driving the nut lead screw by electric reduction. Clutchless electric pressing is adopted, and the electric drive controls the DS / OS sides independently of each other, completely relying on the computer according to the detection signal of the position sensor, with the position closed-loop control as the outer loop and the speed as the inner loop to realize the synchronization of pressing on both sides of the DS / OS . Its control interlock is complex. Every time the mechanical equipment is overhauled, the electrical disassembly and inspection of the pressing position sensor needs to be carried out by adjusting the height of the screw nut. At this time, the conditions on site do not meet the o...
