Description

The anti-device that sticks up of a kind of reversible plate mill

Technical field

The utility model belongs to steel rolling and uses the plate mill technical field.Be specifically related to the anti-device that sticks up that a kind of reversible plate mill prevents that in rolling process rolled piece from upwarping.

Background technology

The reversible plate mill has dissimilar, and is widely used in iron and steel, nonferrous metallurgy industry.For example; Two roller reversible hot rolled steel plate milling trains of iron and steel metallurgical industry; Two rolls are installed on the frame along a vertical plane overlapping (the superposed bottom roll that cries of calling roll, being positioned at the bottom); The central axis of two rolls is parallel with horizontal plane and be positioned at a vertical plane of frame, and the extended distance between the roll (being called roll gap) can be regulated through press down system, two rolls can along roll mandrel center line separately just/reverse rotation; Being furnished with in the both sides of frame can be just/the rolled piece rollgang of opposite spin, and the roller-way upper level generally is lower than the roll surface top of bottom roll slightly.Be heated to the slab (or slab ingot) of set point of temperature through heating furnace; Roller-way by milling train one side is transported to milling train; Nip roll gap (the roll gap size is littler than slab thickness, base is thick-roll gap=drafts) and spue from the frame opposite side of the roll that is rotated arrives the rollgang of opposite side; Thereby accomplish the rolling of a passage, rolled piece (slab) is thinned once; Then, regulate (minimizing) roll gap, and operation rollgang and roll counter-rotation; Drive the rolled piece counter motion and by the roll roll gap of nipping for the second time; Spuing from opposite side arrives the rollgang of opposite side, thereby accomplishes the rolling of second passage, and rolled piece (slab) is thinned again once; , so back and forth rolling, every rolling passage, rolled piece just is thinned once, until the finished steel plate thickness that rolls plan.The thickness of every time attenuate is called reduction in pass, the rolled piece thickness difference before and after promptly nipping.The process of Here it is plate mill rolled plate.

The reversible plate mill in rolling process because the influence of various factors (like rolled piece along the thickness direction temperature distributing disproportionation, rolled piece is different with the coefficient of friction of roll contact-making surface cause about the differences of frictional force of contact-making surface; The top and bottom rolls roller directly there are differences, and the linear velocity of top and bottom rolls roll surface is different, and the importing angle of rolled piece is unreasonable; Or the like), cause the difference of the different parts (particularly thickness direction) of rolled piece cross section at the metal flow of unit interval unit are, cause rolled piece bent to a lateral bending of metal flow less (also being that the flow of metal degree is less); Thereby rolled piece occurs when milling train spues, rolled piece head, tail or middle any position exist to upwarp or the phenomenon of button down; Because rolled piece receives the restriction (when rollgang was the flower roller, confinement effect was better) of rollgang roll surface when detaining down, following button can be suppressed; But upwarp comparison " freedom ", therefore, the easy appearance of rolled piece seriously upwarps; Generally be called " nose ", upwarp when serious, rolled piece possibly dash from exporting; Damage the auxiliary equipment on the frame, perhaps can't descend rolling (rolled piece is not straight, down one the difficulty of nipping) of a time; Useless in the middle of causing, if upwarp together at last seriously, it is useless just to become the underproof finished product of plate shape.

In order to overcome the rolled piece end bending problem of reversible plate mill, the measure of taking usually has:

(1) reduces rolling line speed difference up and down, prevent that the rolled piece that top and bottom rolls linear velocity difference causes is bent to a slow-footed lateral bending;

(2) the roller footpath of minimizing top and bottom rolls is poor, prevents that top and bottom rolls from causing rolled piece bent to the big lateral bending of pressure to the pressure difference of rolled piece;

(3) optimize the heating process of slab, reduce and eliminate the rolled piece cross section temperature difference, prevent the extension along with rolled piece, the flow of metal degree is different and rolled piece that cause is bent to the less lateral bending of deformation extent.

(4) give rolled piece surface de-scaling (removing removing iron scale), guarantee that the material on top and bottom rolls surface is identical with roughness, prevent that rolled piece upper and lower surfaces andfrictional conditions is different and rolled piece that cause is crooked.

(5) be provided with and adjust rational height of rolling line, reasonably imported angle (angle of rollgang or breast roll upper surface and bottom roll upper surface line and roll line), reduce to import the angle when stinging steel and change and cause the workpiece front end bending.

Because the limitation of equipment configuration, the not every cover plate mill of above measure can both adopt, even can adopt, its effect also there are differences.The reversible that is used for the pilot scale of the sheet material kind two roller plate mills of Iron and Steel Enterprises in China part pilot plant configuration particularly, in order to reduce investment, the equipment configuration is fairly simple; Top and bottom rolls is driven by same motor via reducer and gear-box simultaneously, can't adjust the linear differential of top and bottom rolls, because the milling train miniaturization; Do not have also can't dispose special de-scaling equipment, the height of rolling line that does not have configure dedicated is at line adjusting device, and; Because roll diameter of roller is little, billet bloom size is little, the severity of beating when rolled piece is nipped; Importing angle when causing rolled piece to be nipped comes and go, and above factor causes rolled piece end bending serious and can not take conventional measure to improve and solve.

The patent No. is 200320102827.0; Publication number is CN2670021; The utility model name is called the anti-device that sticks up of a kind of special use; Should anti-stick up device and comprise support, swing type inertia weight, and prick machine width degree direction at the medium plate hot-strip two or more swing type inertia weights are set, swing type inertia weight is connected through movable axis with support.This device utilizes the power effect of being used to of swing weight, consumes the powerful impact moment of steel plate, with nose, stick up the tail steel plate and depress, has solved the steel plate nose, has stuck up the tail problem.But this device is mounted in pedestal, can only be after rolling last passage to production board, and when leaving frame production board had and anti-ly stick up effect, can not prevent the nose phenomenon of the rolled piece in the reversible rolling process.

The utility model content

The purpose of the utility model is the deficiency that overcomes prior art; Provide a kind of reversible plate mill the anti-device that sticks up, this is anti-to stick up device in the operation of rolling, rolled piece is limited between the gap on anti-base plate lower surface that sticks up device and rollgang plane; Can, rolled piece guide rolled piece steadily to nip before nipping; Preventing that rolled piece from scurrying up and down jumps and changes and import the angle, again can be when reverse rolling the spuing of rolled piece, and the restriction rolled piece upwarps; In addition, this prevents sticking up, and apparatus structure is simple, long service life, and the lower surface of its base plate can be changed after being may wear to a certain degree by rolled piece; Can not cause damage to original milling equipment; Do not need to increase in addition power, the operation easy to adjust, practical, easy to utilize.
