Description
Technical Field
The utility model relates to a steel rolling machinery, concretely relates to twenty high rolling mill wiper prevents that belted steel limit portion emulsion from splashing and forming the device of emulsion spot mark on the steel sheet surface.
Background
A twenty-high single stand reversible mill uses an emulsion as a cooling and lubricating medium. The wiper system consists of four outer wiper rollers and an inner rubber baffle strip. The main working principle is that a large amount of emulsion is blocked in the housing by a rubber baffle of the wiper, and the emulsion left on the steel plate is squeezed by a wiper roller. However, the wiper has poor use effect, emulsion splashed at the edge drops on the surface of the steel plate to form emulsion mottle defect, and the cashing of the contract is seriously influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a device is prevented emulsion of twenty-high rolling mill wiper limit portion and is splashed to above-mentioned problem.
the utility model aims to overcome the above-mentioned not enough, perfect wiper structure prevents that the emulsion from splashing out from the wiper both sides, reduces the steel sheet surface because of the defect that the emulsion drips the production to improve steel sheet surface quality.
The technical scheme of the utility model is realized like this: reduce device that twenty-roller mill wiper limit portion brought out emulsion adds the fixed track in wiper both sides, installs movable baffle on the track, and lateral position is adjustable, realizes the effect of blockking to different width steel sheet limit portions splash emulsion.
The twenty-high roll mill wiper edge emulsion splashing prevention device comprises a rail rod and an integral movable baffle, wherein the integral movable baffle comprises a steel pipe, a fixing plate and a replaceable rubber plate, the steel pipe horizontally penetrates through the rail rod, the fixing plate is welded below the steel pipe in parallel, and the replaceable rubber plate is arranged below the fixing plate through a bolt. The rail rod is welded on the wiper frame.
The utility model has the advantages that: the utility model discloses it is unreasonable mainly to have solved present twenty high rolling mill wiper structure, and the emulsion from the wiper roll limit portion of steel sheet both sides fly away in the no steel sheet region gap, drips and forms emulsion spot defect on belted steel surface. The movable baffles are additionally arranged on the two sides of the wiper, so that the emulsified liquid splashed during high-speed rolling is blocked, and the flowing direction of the emulsified liquid is changed. The utility model discloses improve on the wiper basis, realize easily, and prevent that the effect that splashes is obvious, stopped steel sheet surface emulsion spot defect, promoted steel sheet surface quality greatly.
In recent years, due to the change of market supply-demand relationship and the development and application of replacing imported high-end products, the product quality requirement is greatly increased. The surface quality becomes a key factor influencing the redemption of the contract, and particularly, the emulsion spot defect seriously influences the product quality. The invention can effectively solve the spot defect of the emulsion on the surface of the steel plate, improve the surface quality of the product and enhance the competitiveness of the product. After the invention is applied, the defects of the emulsion on the surface of the steel plate are thoroughly solved, and the cost can be reduced by more than 100 ten thousand yuan per year.

Wherein: 1. the device comprises a steel pipe, 2. a metal track, 3. a metal fixing plate, 4. a replaceable rubber plate, 5. a rubber baffle strip, 6. a frame, 7. a wiper roller. The direction of the arrows in the figure is the emulsion flow direction.
Detailed Description
As shown in figure 1, the device for preventing emulsion from splashing on the edge of the wiper of the twenty-high rolling mill comprises a rail rod and an integral movable baffle, wherein the integral movable baffle comprises a steel pipe, a fixing plate and a replaceable rubber plate, the steel pipe horizontally penetrates through the rail rod, the fixing plate is welded below the steel pipe in parallel, and the replaceable rubber plate is arranged below the fixing plate through a bolt. The rail rod is welded on the wiper frame.
As shown in fig. 3, the wiper system is mainly composed of a frame, a wiper roller, and a rubber stopper strip. Wherein the opening and closing of the wiper roller is controlled by a hydraulic cylinder. Firstly, most of emulsion is blocked in the memorial archways by the rubber baffle strips, and then the emulsion left on the steel plates is scraped clean by two groups of wiper rollers which are distributed up and down symmetrically. However, a gap is formed between the edge of the wiper roller and the outside of the steel plate area, and due to the high-speed rotation of the wiper roller, the emulsion is thrown out at a high speed in the gap area to form splashed droplets, and the droplets are gathered and condensed by equipment in a thickness gauge, a housing area and the like and then fall on the surface of the steel plate to form the defect of emulsion spots.
Fig. 2 is a schematic diagram of the application principle of the device of the present invention on a wiper. Comprising a metal track fixed on a large frame of a wiper and an integral movable baffle. Wherein the movable baffle consists of a steel pipe, a metal fixing plate and a replaceable rubber plate. The specific design scheme is as follows: (1) selecting a steel pipe with the inner diameter of 16-17 mm, the thickness of 2mm and the length of 240 mm; (2) a metal fixing plate with the thickness of 3mm multiplied by 30mm multiplied by 240mm is welded on the steel pipe in parallel; (3) selecting a rubber plate with the thickness of 3mm multiplied by 300mm multiplied by 240mm, fixing the rubber plate on a metal fixing plate through screws, and finishing the design and manufacture of the movable baffle. (4) A solid steel rod 400mm in length and 15mm in diameter was welded as a rail to the wiper frame. (5) The movable baffle is sleeved on the track. According to the width change of the steel plate, the distance between the movable baffle and the edge of the steel plate is 5mm, and the flowing direction of the emulsion at the edge part is stopped and changed. The emulsion is effectively prevented from dripping on the surface of the steel plate after splashing, and the surface quality of the steel plate is greatly improved.
(1) The utility model changes the flow direction of the emulsion brought out from the edge part and guides the brought-out emulsion to the emulsion recovery system;
(2) The baffle plates are positioned on two sides of the wiper, and the position of the baffle plates can be adjusted, so that the baffle plates can adapt to rolling of band steel with different widths;
(3) The replaceable rubber plate is made of rubber, is convenient to replace, has certain elasticity, plays a role in buffering the impact of emulsion, and enhances the blocking effect.
(4) The device is simple, easy to manufacture and convenient to install and use.
The above description is only for the specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any person skilled in the art can make changes or modifications within the scope of the present invention.
