Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of equipment for measuring thickness of finished steel rolling products, in particular to a device for preventing iron oxide scale of a thickness gauge from falling off. Background Art
[0002] The thickness gauge is a very important thickness measuring device in hot rolling production. The stable operation of the equipment can directly affect the thickness accuracy of the finished steel products and the stable operation of the finishing thickness control model. Due to the insufficient protection measures of the existing thickness gauge, a large amount of iron oxide scale will adhere to the surface of the strip during normal production. After passing through the F7 rolling mill, some of the iron oxide scale will fall off. The thickness gauge is located at the exit of the F7 rolling mill, and its measuring window is located below the strip. Some of the fallen iron oxide scale will fall on the measuring window of the thickness gauge, which will directly affect the measurement accuracy of the thickness gauge and the stable operation of the AGC closed-loop control of the finishing thickness control model. In severe cases, it will cause hot stop time for the finishing steel pile. Therefore, a device is used to prevent the oxidized iron scale from falling off the thickness gauge. After the anti-falling device is installed, the oxidized iron scale will first fall onto the anti-falling baffle, then the anti-falling device cover, and then fall onto the thickness gauge window after passing through two purge winds above the thickness gauge window. After the above three interceptions, the probability of the oxidized iron scale falling can be greatly avoided, and thermal shutdown failures caused by the falling of the oxidized iron scale can be avoided.
