Above-mentioned descaling mill high pressure nozzle de-scaling watermark testing arrangement, the two ends of said watermark test board are fixed on the gripper shoe by pressing plate, and there is screw at the gripper shoe two ends, and corresponding screw is arranged respectively on pressing plate, the lateral adjustment location-plate, and set bolt is through in the screw.
Above-mentioned descaling mill high pressure nozzle de-scaling watermark testing arrangement has the thickness adjusted pad between the pressing plate in the said watermark test board outside and the gripper shoe.
Above-mentioned descaling mill high pressure nozzle de-scaling watermark testing arrangement; Along the rolling direction order many group watermark test boards and gripper shoe are installed; There is the hoisting and locating plate at the two ends of every group of watermark test board and gripper shoe, are connected through attachment bolt by the lateral adjustment location-plate between two groups of watermark test boards and the gripper shoe.
Watermark test board of the present invention is to be made by special rubber slab, under the percussion of descaling mill high pressure nozzle, can stay tangible watermark, and can collect and carry out the scale removal effect contrast.The watermark test board is installed in about the gripper shoe, can carry out height according to the position of last lower collector pipe and regulate, and has satisfied the watermark test request of different slab thicknesses and collector height,
The present invention regulates the height and the lengthwise position of watermark test board through hoisting and locating plate, lateral adjustment location-plate and thickness adjusted pad; And can customize gripper shoe and the watermark test board that adapts according to the slab rolling width; This design has improved the scope of application of the present invention; Realize the design object that many groups descaling header is tested simultaneously, satisfied descaling mill collector nozzle watermark test request.

Mark is following among the figure: descaling mill descaling header 1, descaling mill rollgang 2, watermark test board 3, pressing plate 4, thickness adjusted pad 5, gripper shoe 6, hoisting and locating plate 7, suspension ring 8, lateral adjustment location-plate 9, attachment bolt 10, set bolt 11.
The specific embodiment
The present invention is made up of watermark test board 3, gripper shoe 6, pressing plate 4, thickness adjusted pad 5, hoisting and locating plate 7, lateral adjustment location-plate 9, and hoisting and locating plate 7 has two respectively with lateral adjustment location-plate 7.
Show among the figure that watermark test board 3 is to be made by special rubber slab, under the percussion of descaling mill high pressure nozzle, can stay tangible watermark, and can collect and carry out the scale removal effect contrast.Watermark test board 3 is installed in the upper and lower both side surface of gripper shoe 6; Can carry out height according to the position of last lower collector pipe and regulate, satisfy the watermark test request of different slab thicknesses and collector height, simultaneously in order to save the spare part kind of gripper shoe in the testing arrangement; The thickness of gripper shoe 6 is fixed; Test board can install the old test board of many groups additional if will regulate height in the middle of new test board and gripper shoe 6, thickness compensation is carried out with thickness adjusted pad 5 in its both sides, thereby reaches the height of watermark test board 3.
