Abstract
Description
Technical Field
[0001] The utility model relates to an oil sludge connection groove device for the side wall of an outer cover of an inlet frame of a cold rolling skin-pass mill, and belongs to the technical field of auxiliary equipment for cold-rolled strip steel production in the metallurgical industry. Background Art
[0002] The flattening mill is one of the important equipment in the cold rolling process and is crucial to the production of high-end surface of the strip. The flattening mill includes a frame cover, a steering roller and a high-pressure water nozzle of the wet roller system. The side wall of the frame cover is located above the strip and its width is greater than the width of the strip. The steering roller is the guide roller for the strip to enter the flattening mill. The strip needs to be supported by the guide roller. The high-pressure water nozzle of the wet roller system sprays the upper and lower surfaces of the strip entering the flattening mill. The spraying causes water mist to diffuse at the entrance of the flattening mill. The water mist and the oil mist of the flattening mill are mixed and condensed and attached to the side wall of the frame cover to form sludge. The sludge on the side wall of the frame cover drips to the surface of the strip below after aging to form oil spots. Oil spots are a typical flat surface quality defect, which will cause the quality of the product to be reduced. Therefore, a simple and effective sludge receiving trough device is designed to prevent the sludge from dripping directly from the side wall of the frame cover at the entrance of the flattening mill to the surface of the strip. Utility Model Content
[0003] The utility model aims to provide an oil sludge receiving groove device for the side wall of the outer cover of the entrance frame of a cold rolling mill, which can prevent the oil sludge from dripping directly from the side wall of the outer cover of the frame of the flattening mill to the surface of the strip, protect the surface of the strip, and solve the problems existing in the background technology.
[0004] The technical solution of the utility model is:
[0005] A sludge receiving groove device for the side wall of the outer cover of the entrance frame of a cold rolling mill comprises a side wall of the outer cover of the frame of the leveling mill, a guide roller and a high-pressure water nozzle. The side wall of the outer cover of the frame of the leveling mill is located above the strip steel, and its width is greater than the width of the strip steel. The guide roller is a guide roller for supporting the strip steel entering the leveling mill. The high-pressure water nozzle sprays toward the strip steel. An sludge receiving groove is arranged in the width direction of the side wall of the outer cover of the frame of the leveling mill. The length of the sludge receiving groove is the same as the width of the side wall of the outer cover of the frame of the leveling mill, and the cross-section of the sludge receiving groove is W-shaped.
[0006] The oil mud connection groove is an integrated structure consisting of a middle bonding plate and grooves on both sides of the bonding plate, and its cross section is W-shaped.
[0007] The width of the bonding plate in the middle of the oil mud receiving groove is less than or equal to the thickness of the side wall of the outer cover of the leveling machine frame, and the length is equal to the width of the side wall of the outer cover of the leveling machine frame.
[0008] The bonding plate in the middle of the oil mud receiving groove is fixed to the side wall of the outer cover of the leveling machine frame by bolts.
[0009] The grooves on both sides of the bonding plate are V-shaped and symmetrically arranged along both sides of the bonding plate.
[0010] The oil mud receiving groove on the width direction of the side wall of the frame outer cover of the leveling machine is located above the strip steel.
[0011] The utility model has the beneficial effects of simple structure, easy cleaning, and the ability to block oil sludge from directly dripping from the side wall of the flattening machine frame outer cover to the surface of the strip steel, thereby effectively protecting the surface of the strip steel.

[0016] The present invention will be further described below by way of examples with reference to the accompanying drawings.
[0017] See attached Figure 1 , 2 3. A sludge receiving groove device for the side wall of the entrance frame cover of a cold rolling mill, comprising a side wall 2 of the frame cover of the leveling mill, a guide roller 3 and a high-pressure water nozzle 4. The side wall 2 of the frame cover of the leveling mill is located above the strip, and its width is greater than the width of the strip. The guide roller 3 is a guide roller for supporting the strip to enter the leveling mill. The high-pressure water nozzle 4 sprays toward the strip. An sludge receiving groove 8 is arranged in the width direction of the side wall 2 of the frame cover of the leveling mill. The length of the sludge receiving groove 8 is the same as the width of the side wall 2 of the frame cover of the leveling mill, and the cross-section of the sludge receiving groove 8 is W-shaped.
[0018] In this embodiment, the side wall 2 of the outer cover of the leveling machine frame, the guide roller 3 and the high-pressure water nozzle 4 are the known technical contents of the leveling machine, as shown in the attached Figure 1 shown.
[0019] See attached Figure 1 , 23. The oil mud connection groove 8 is made of a stainless steel plate with a thickness of 2.0 mm, and includes a middle bonding plate 5 and grooves 7 on both sides of the bonding plate 5. The bonding plate 5 is rectangular, with a length of 2300 mm and a width of 100 mm. Its width is less than the thickness of the side wall 2 of the outer cover of the leveling machine frame, and its length is equal to the width of the side wall 2 of the outer cover of the leveling machine frame. There are 7 screw holes 6 in the length direction of the bonding plate 5, and the outer circle diameter of the screw holes 6 is 30 mm and the spacing is 250 mm. The grooves 7 on both sides of the bonding plate 5 are 100 mm deep, 150 mm wide, and the bottom angle is 90°.
