Abstract
A rolling mill for hot-rolling plate or band is composed of a machine frame, the upper and lower roller holders, the upper and lower roller systems consisting of a working roller and two supporting rollers, which are arranged in triangular mode, and a pressing down unit for regulating the pass between upper and lower working rollers.
Description
(1) technical field
The present invention relates to a kind of milling train, particularly relate to the new three roller rolling mill for hot rolled planks and strips of a kind of high accuracy.
(2) technical background
At present, the structure of rolling mill for hot rolled planks and strips all adopts the mode of little working roll and big backing roll, roll-force is delivered on the backing roll through working roll, roller is the intensity that intensity depends primarily on backing roll, the rigidity of milling train depends on the rigidity of frame and roller system, and shut out high-precision hot rolled strip needs the complicated system of a cover to support.
There are many drawbacks in above structure, and milling train main equipment weight is big, and large-scale supporting roller cost height needs main equipment to process; Because the structure problem of milling train own, production high accuracy band, must be aided with modes such as design roll shape, string roller, roller, need large-scale template instrument simultaneously, cause rolling up of investment, increased maintenance difficulties and maintenance cost.
(3) summary of the invention
The object of the present invention is to provide a kind of high accuracy rolling mill for hot rolled planks and strips, this milling train is applicable to the rolling of whole hot rolled strips, has solved the ultrawide strip milling equipment and has made problem of difficult.
The technical scheme that adopts is:
A kind of rolling mill for hot rolled planks and strips, comprise a frame, roller seat, up-down rollers system and be used to adjust the screwdown gear of working roll roll gap up and down, upper and lower roll system respectively comprises a working roll and two backing rolls, it is characterized in that described working roll and backing roll constitute triangle, the backing roll diameter in the outside is less than inboard work roll diameter.
Above-mentioned screwdown gear acts on one's body the working roll by last roller seat.
The body of roll and the screwdown gear of above-mentioned backing roll support by back lining bearing.
The present invention has the following advantage that is different from traditional rolling mill for hot rolled planks and strips:
1, the huge backing roll system of cancellation thoroughly solves the amount of deflection problem of roll in plate strip rolling process with simple screwdown gear.
2, milling train does not need to go here and there means such as roller, roller, can reach higher rolling accuracy, and lateral error is less than 10 μ m/m.
3, this milling train operating cost is low, and roll campaign is long, does not need huge roll lathe, grinding machine, the also corresponding reduction of factory building cost.
4, this milling train scope of application is extremely wide, has solved the ultrawide strip milling equipment and has made problem of difficult, can the following strip of rolling width 800mm, and its version can be eliminated traditional rolling mill for hot rolled planks and strips fully.
(4) description of drawings
Fig. 1 is the structural representation of an embodiment of the present invention.
Reference numeral: 1-rolled piece; The 2-working roll; The 3-backing roll; The last roller seat of 4-; The 5-screwdown gear; The 6-frame; The 7-lower roller base.
(5) specific embodiment
See also Fig. 1, a kind of rolling mill for hot rolled planks and strips of the present invention comprises frame 6, goes up roller seat 4, lower roller base 7 and upper and lower roll being.Upper and lower roll system respectively comprises a working roll 2 and two backing rolls 3, and the outside of working roll 2 contacts with the inboard of two backing rolls 3, the diameter of inboard working roll 2 is greater than the diameter of two backing rolls 3 in the outside, and rolled piece 1 is folded between the working roll 2 of upper and lower roll system.Be equiped with screwdown gear at last roller seat 4 and 6 of frames, this screwdown gear is well known to those skilled in the art, so will not launch explanation, screwdown gear 5 can be used for adjusting the size of working roll roll gap, the maximum rolling force that roll bore by the non-transmission of force analysis depends primarily on the bending stress of the maximum that this roll can bear, by the adjustment of roller seat and depressing position up and down, the maximum stress in bend that roll is born has not constituted the restrictive condition of roll strength, the working roll at middle part, mainly satisfy the transmission problem, like this, traditional huge backing roll is replaced with two little backing rolls, saved roll material greatly.
Claims (3)
1, a kind of rolling mill for hot rolled planks and strips comprises frame, roller seat, up-down rollers system and screwdown gear up and down; Up-down rollers system respectively comprises a working roll and two backing rolls, screwdown gear is arranged between roller seat and the frame, it is characterized in that: working roll and two backing rolls that described up-down rollers is all constitute triangle, and the diameter of two backing rolls in the outside is less than the diameter of inboard working roll.
2, a kind of rolling mill for hot rolled planks and strips according to claim 1 is characterized in that described screwdown gear acts on the body of roll of working roll by last roller seat.
