Abstract
The invention discloses equipment for continuously rolling metal plates and strips, which belongs to the technical field of the continuous rolling of metal plates and strips and is applicable to the continuous rolling production line of metal plates and strips. The equipment is characterized in that a rough rolling unit, a middle rolling unit and a fine rolling unit in the production line respectively consist of a base, and a motor, a speed reducer gearbox, a gear distribution box and a plurality of double-roller plate and strip rolling machines thereon; the inlet and the outlet of each rolling machine are respectively provided with a guiding and guarding device. The equipment is also characterized in that a left frame and a right frame are closed by stop bolts to form the frame of the double-roller plate and strip rolling machine; the shape of the flame is rectangular when seen along the rolling direction; housing screws, which are used for regulating the spacing between the rollers, are arranged in corresponding positions both on the upper surface and lower surface of the frame; the double-roller plate and strip rolling machine adopts surface contact roller supporting systems arranged in sections; the surface contact roller supporting systems of the double-roller plate and strip rolling machine are arranged between the frame and the internal rollers of the frame; each surface contact roller supporting system consists of two supporting blocks; the contact surfaces of the supporting blocks and the rollers are coated with an antifriction material; a technical lubricating system continuously supplies the surfaces of the supporting blocks with a lubricant; and a regulating device is used for regulating the contact pressure between the supporting blocks and the rollers so as to change the deflection of the rollers.
Description
Technical field
The invention belongs to the metal plates and strips rolling technical field, be specifically related to used equipment in a kind of rolled metal strip material continuous rolling production line.
Background technology
At present, rolled metal strip material has dual mode, and a kind of is that common plate hoop mill reversible is rolling, rolling mode is that rolled piece is rolled in the past by a side of milling train earlier, and rolled piece is rerolled in rolling mill roll opposite spin then, repeat-rolling like this is up to rolling out finished product; Another kind is the logical strip-mill strip continuous rolling of many Daeporis that in-line is arranged, by each milling train, thickness constantly reduces rolled piece, up to rolling out finished product by passage.The used equipment of these two kinds of rolling modes all is the common plate hoop mill, because board rolling requires roller diameter little, therefore in order to satisfy roll in the requirement aspect the strength and stiffness, needs breaker roll to support.The common plate hoop mill adopts backing roll supporting working roll, thereby has produced four roller strip-mill strips and multi roller band milling train.Adopt the shortcoming of backing roll supporting working roll to be: (1) working roll and backing roll are in theory for line contacts, and surface contact stress is big, high-frequency change stress state, and material is easy to produce fatigue damage, reduction roll service life.(2) working roll contacts with the backing roll line, causes roll to be in unstable stress, need apply horizontal supporting to it.(3) backing roll is bulky, and the bending resistant section coefficient is low, and the material effective rate of utilization is low.(4) backing roll is made difficulty, processing charges height.(5) milling train is bulky, and stress line is long, causes mill stiffness to reduce.(6) be delivered on the frame by back-up roll bearing owing to roll-force, so back-up roll bearing costs an arm and a leg maintenance technique requirement height.
Summary of the invention
The purpose of this invention is to provide a kind of new continuously rolling metal plates and strips production line device therefor, can satisfy the production requirement of low, the many kind of cost, high accuracy, high-test metal strip material effectively.
The present invention is achieved in that its technological process of production is:
Roughing unit, middle milling train group and mm finishing mill unit are respectively motor to be installed drive some two roller strip-mill strips compositions by reduction box and gear distribution box on a support; Guide and guards is equipped with in porch and exit at every milling train; The frame of described two roller strip-mill strips involutes left frame and right frame, the shape of this frame is to be seen as rectangle along rolling direction, on the above and below of frame with on the corresponding position of roll device the housing screw that is used to adjust the roll shop building distance is being installed; The face contact roll bearing system that described two roller strip-mill strips adopt segmentation to be provided with, described contact roll bearing system is installed between interior roll of frame and the frame.
Advantage of the present invention and good effect are:
(1) adopted on the support and to drive some two roller strip-mill strips by motor by reduction box and gear distribution box and be rolled, the set structure compactness has been saved floor space and equipment investment.
(2) the face contact roll bearing system that adopts segmentation to be provided with greatly reduces contact surface stress, has improved the material behaviour in service.
(3) two roller strip-mill strips adopt the opposite opened frame of rectangle, and equipment volume is little, and the mill stiffness height reduces the spring amount of roll gap, thereby has guaranteed the precision of rolled piece, also is convenient to processing, dismounting and the replacing of frame.
(4) can make roll be in stable state at vertical and horizontal both direction back up roll.
(5) because the milling train cost significantly reduces, can change the specification of product by increase and decrease frame quantity.
(6) be applicable to hot continuous rolling and cold continuous rolling production line, the kind of product is increased.
Description of drawings
The face that Fig. 1 is provided with for segmentation contacts the milling train figure of roll bearing system;
Among the figure: the 1-left frame; The right frame of 2-; The 3-attachment bolt; The 4-rest pad; The 5-adjusting device; The 6-antifriction material; The 7-travelling gear; The 8-roll device; 9-face contact roll bearing system; The 10-positioner; The 11-housing screw; The 12-shaft coupling.
The specific embodiment
The technological process of production of the present invention is: blank is entered rolling in the roughing unit of forming by some two roller strip-mill strips → enter by roller-way rolling in the middle milling train group of forming by some two roller strip-mill strips → enter by roller-way rolling in the mm finishing mill unit of forming by some two roller strip-mill strips → enter coiling machine rolled piece is coiled into strip volume → collect warehouse-in by the induction system production board roll coil of strip.
The structure of described two roller strip-mill strips is to connect the frame that forms by left frame 1 and right frame 2 by attachment bolt 3, the shape of this frame is to be seen as rectangle along rolling direction, on the above and below of frame with on the roll device 8 corresponding positions housing screw 11 that is used to adjust the roll shop building distance is being installed, the face that is provided with by segmentation contacts the amount of deflection that roll bearing system 9 adjusts two rolls, and the face contact roll bearing system of segmentation setting is installed between interior roll of frame and the frame.
The face contact roll bearing system that described segmentation is provided with is made up of two rest pads 4, the surface that rest pad contacts with roll scribbles antifriction material 6, provide lubricant by process lubrication system continuously for the rest pad surface, adjust the pressure that contacts between rest pads and the roll by adjusting device 5, in order to change the amount of deflection of roll.
