[0002] The roughing mill is a four-roll reversing mill for hot coiling, which is mostly used for rolling slab steel. Currently, in order to reduce the temperature loss of slab steel and improve steelmaking efficiency, the existing rolling mills are often equipped with multiple insulation covers.

[0003] However, sometimes, the head of the slab steel will curl up because the steel temperature is too low, forming a warping phenomenon. At this time, if the operator does not discover it in time, the slab steel will directly hit the insulation cover due to inertia. Therefore, the entire production line needs to be shut down for maintenance, which will eventually affect production capacity. Summary of the Invention

An automatically triggered height detection component is arranged in front of the insulation cover, which can timely detect the warping phenomenon of the slab steel. In this way, the utility model can prevent the insulation cover from being hit, reduce the number of maintenance times, and improve production efficiency.

[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0032] The utility model provides an automatic anti-collision device for detecting the warping of the intermediate slab of hot-rolled plate, comprising a rolling mill with a transmission roller inside for transmitting slab steel; a plurality of heat-insulating covers evenly distributed along the length of the rolling mill, which cover the upper part of the rolling mill for the slab steel to pass through; a rotating roller arranged above the rolling mill and in front of the entrance of the heat-insulating cover, the rotating roller being provided with a touch rod extending toward the transmission roller; an angle sensor arranged at the end of the rotating roller; a drive push rod arranged on both sides of the heat-insulating cover for lifting the heat-insulating cover; and a controller, the signal input end of which is electrically connected to the angle sensor, and the signal output end of which is connected to the drive push rod. The height of the heat-insulating cover is 400-500 mm, and the bottom end of the touch rod is 350-400 mm away from the rolling mill track.

[0033] This device sets a detection component at the entrance of the heat preservation cover. When encountering the warped head of the slab steel, the touch rod in the detection component will be pushed to move; at this time, the controller connected to the touch rod can receive the movement signal of the touch rod and issue an early warning; thus, this device can timely detect the warping of the slab steel and prevent damage to the production line.

[0034] At the same time, by setting a driving push rod, the insulation cover can be automatically lifted; then, when the controller receives the movement signal of the touch rod, the controller will immediately control the driving push rod to lift the insulation cover; then, this device can prevent the insulation cover from being hit while processing slab steel without stopping the machine, thereby improving the working efficiency of the production line.

[0035] Sometimes the lowest passing height of the heat preservation cover will change. In order to solve the problem of inconsistent limit heights, as an embodiment of the present device, the touch rod in the present device is configured as a telescopic rod so that it can be extended and retracted along its own central axis.

[0036] As another embodiment of the present device, the present device is provided with a touch rod rotatably connected to the rotating roller, and is raised and lowered in a direction perpendicular to the central axis of the rotating roller; wherein the touch rod is a threaded rod; at the same time, a threaded hole is opened on the rotating roller in a direction perpendicular to the central axis of the rotating roller; therefore, the touch rod is inserted into the threaded hole and is spirally raised and lowered along the threaded hole.

[0037] In order to ensure the stable rotation of the rotating roller, the device is fixed at both ends of the rotating roller by fixing support plates.

[0038] Working principle:

[0039] As the slab advances in the rolling mill, when the warped end of the slab encounters the touch rod, the touch rod is pushed to move. At this point, the controller connected to the touch rod receives the movement signal of the touch rod, issues an early warning, and sends a signal to the controller.

[0040] Then, the controller controls the driving push rod to start and lift the heat preservation cover; thus, the slab steel passes through the heat preservation cover smoothly.
