Abstract
The utility model relates to a control device for an overhead stander looper of a fault rolling mill, and belongs to auxiliary equipment for production in the metallurgy industry. The control device comprises a computer and a hydraulic cylinder, wherein the hydraulic cylinder is connected with an electro-hydraulic servo valve through a pipeline, and the electro-hydraulic servo valve is connected with the computer. The control device is connected with a looper roll, and can automatically control the loop of a hot rolling strip steel through computer program software when the stander is overhead in fault, so as to solve the problem of scuffing on the surface of the strip steel caused by fault overhead looper equipment of the stander, solve the problem of drifting of the strip steel when the hot continuous fine rolling stander is overhead in fault, and reduce the time for treating the fault.
Description
Technical field:
The utility model belongs to metallurgy industry production auxiliary equipment, is specifically related to the control device that the trouble rolling mill sky is established the frame kink.
Background technology:
Under the machinery or electric out of order situation of finish rolling district frame, kink position when sky is established frame steel rolling between the corresponding frame generally is in the holding fix that is lower than rolling centerline, do not control, when being with steel, can cause belt steel surface to scratch, influence product quality by loop back roll and its rebound.
Summary of the invention:
In order to solve since the frame sky when establishing kink equipment cause the problem of steel strip surface defect, the utility model provides the trouble rolling mill sky to establish the control device of frame kink.
The realization the technical solution of the utility model is: comprise computer, hydraulic cylinder, hydraulic cylinder connects electrohydraulic servo valve, and electrohydraulic servo valve connects computer.
The utility model is connected with loop back roll, can make hot-strip kink when the frame failure null realize control automatically by computer software, thereby solved because the problem that the belt steel surface that frame failure null kink equipment is caused scratches, band steel whipping problem when simultaneously also having solved hot-rolling finishing mill frame failure null, and reduced time of handling failure.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the working procedure FB(flow block) of the utility model embodiment.
Among the figure: 1, computer 2, lead 3, electrohydraulic servo valve 4, hydraulic cylinder 5, pipeline
The specific embodiment:
Embodiment: shown in Figure 1, present embodiment comprises computer 1, hydraulic cylinder 4, hydraulic cylinder
4 by pipeline 5 connection electrohydraulic servo valves 3, and electrohydraulic servo valve 3 connects computers 1.
The utility model implementation process realizes automatically in computer program that fully it will be set according to the fault frame.Operation principle of the present utility model is: selected on man-machine picture by the operative employee when the frame fault, just drop into the additional given algorithm program of kink control by the one-level computer according to band steel tracking signal and selection signal afterwards according to the load of the frame after fault frame connection signal, by electrohydraulic servo valve and the action of Driven by Hydraulic Cylinder loop back roll, so that guarantee band steel normal threading and rolling automatic control.
Illustrate: the electrohydraulic servo valve in the present embodiment adopts Rexroth, and model is: 4WRGE10V1-100L; Hydraulic cylinder adopts model to be:
