Adjusting method for water baffle of rolling mill

Abstract

The invention discloses a method for adjusting a water baffle of a rolling mill, which comprises the following steps of: welding a lengthened force arm on the water baffle, mounting a rotatable adjusting stop block on a rack housing, and adjusting a gap according to the abrasion condition of a bakelite plate on the water baffle; when the water retaining effect is not good, the water retaining plate is pushed forwards, the adjusting check block clamps the blocking piece welded to the lengthened force arm, and the water retaining effect is guaranteed. After the water baffle is abraded, the position of the water baffle can be adjusted in time, so that the water baffle is tightly attached to the roller.

Description

Technical Field

[0001] The invention relates to the field of rolling mills, and in particular to a method for adjusting a water retaining plate of a rolling mill. Background Art

[0002] The water baffle of the rolling mill is an important part of the rolling mill. It is a protective device designed for rolling mill equipment. Its main function is to prevent the cooling water generated during the rolling process from dripping onto the surface of the red steel, causing the rolling temperature to drop, affecting the quality of the finished product, and increasing the force, resulting in unstable rolling process. Therefore, it is necessary to ensure that the water baffle fits the roller so that the water flows from both sides of the water baffle and does not directly drip onto the surface of the red steel.

[0003] The existing rolling mill water baffle is compacted by cylinders, but due to the harsh working conditions during on-site rolling, the pneumatic components are severely corroded and fail to work in many cases, causing cooling water to directly splash onto the red steel surface.

[0004] Therefore, it is necessary to develop a new rolling mill water baffle adjustment method to ensure that the water baffle fits the roller. Summary of the invention

[0005] Purpose of the invention: In view of the shortcomings and defects of the prior art, the present invention provides a method for adjusting a water baffle of a rolling mill, which can timely adjust the position of the water baffle after the water baffle is worn, so that the water baffle fits tightly to the rolling roller.

[0006] Technical solution: A method for adjusting a water baffle plate of a rolling mill according to the present invention comprises welding an extended lever arm on the water baffle plate, installing a rotatable adjustment block on the frame arch, and adjusting the gap according to the wear of the bakelite board on the water baffle plate; when the water-blocking effect is not good, the water baffle plate is pushed forward to clamp the adjustment block on the baffle plate welded on the extended lever arm to ensure the water-blocking effect.

[0007] When replacing the rolling mill rolls, pull the water baffle plate out along the rotating shaft and insert the baffle plate into the last adjustment groove. At this time, the water baffle plate is fixed and the bearing seat can be pulled out.

[0008] Among them, the adjustment groove corresponds to the usable length of the bakelite board on the water retaining plate. When the bakelite board is replaced, the baffle is located at the outermost adjustment groove. When the bakelite board is scrapped, the baffle is located at the innermost adjustment groove.

[0009] Wherein, the rotating shaft, water retaining plate, bakelite board and roller are connected in sequence.

[0010] Wherein, a cooling water head is provided on the side of the water baffle.

[0011] Wherein, the rolling roller is located in the bearing seat.

[0012] The adjusting block is provided with an adjusting block rotating shaft, a groove for roller changing and a plurality of adjusting grooves.

[0013] Wherein, a blocking piece is welded on the extended lever arm.

[0014] Wherein, the blocking piece is located in one of the plurality of adjustment grooves.

[0015] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: the present invention can conveniently adjust the fit between the water retaining plate and the roller, is easy to manufacture, and can still be used in harsh environments. During the production process, the operator can also make adjustments outside the rolling mill, which is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The rolling mill water baffle adjustment method of the present invention is as follows: an extension lever arm 9 is welded on the water baffle 2, a rotatable adjustment block 8 is installed on the frame arch 7, and the gap is adjusted according to the wear of the bakelite board 4 on the water baffle 2; when the water-blocking effect is not good, the water baffle 2 is pushed forward, and the adjustment block 8 is clamped on the baffle plate 12 welded on the extension lever arm 9 to ensure the water-blocking effect.

[0024] When replacing the roller 5, the water baffle plate 2 is pulled out along the rotary shaft 1 and the baffle plate 12 is inserted into the last adjustment groove 13. At this time, the water baffle plate 2 is fixed and the bearing seat 6 can be pulled out.

[0025] The adjustment groove 13 of the present invention corresponds to the use length of the bakelite board 4 on the water baffle 2. When the bakelite board 4 is replaced, the baffle 12 is located at the outermost adjustment groove 13. When the bakelite board 4 is scrapped, the baffle 12 is located at the innermost adjustment groove 13. The rotating shaft 1, the water baffle 2, the bakelite board 4, and the roller 5 are connected in sequence. A cooling water head 3 is provided on the side of the water baffle 2. The roller 5 is located in the bearing seat 6. The adjustment block 8 is provided with an adjustment block rotating shaft 10, a groove 11 for changing rollers, and a plurality of adjustment grooves 13. A baffle 12 is welded on the extension arm 9. The baffle 12 is located in one of the plurality of adjustment grooves 13.
