Abstract
The invention discloses a high-rigidity roll system structure for a twenty-roll rolling mill, wherein D1 refers to the diameter of working rolls, D2 refers to the diameter of first intermediate rolls, D3 refers to the diameter of second intermediate rolls, and D4 refers to the diameter of back lining bearings; and the diameter ratio of various rolls has the following relationship: D1:D2 = D2:D3 = D3:D4 = 0.59-0.63, and the diameter of the working rolls is between 58 and 75 millimeters. The optimum value of the diameter ratio of various rolls is 0.618, and the optimum value of the diameter of the working rolls is 70 millimeters. As for the roll system structure for the twenty-roll rolling mill, the diameter ratio of the various rolls is between 0.59 and 0.63. The roll system structure by adoption of the value region improves the rigidity of the rolling mill, adopts the metric standard unit, is convenient to process and guarantees the processing precision. Moreover, the diameter of the various rolls is more than the corresponding prior roll diameter, so that the roll system structure increases the spacing between the rolls, increases the space, and is convenient to lubricate and cool.
Description
Technical field
The invention belongs to the steel rolling equipment field, refer in particular to a kind of roll system structure of mill.
Background technology
Metallurgical industry faces one of most important task, is by developing new technical process and improve existing technical process, improving the metallurgic product quality greatly, comprising the quality of thin plate band.Effect is mill the most widely in multi-roll mill, mill can be produced the flat cold-rolled sheet and the strip of high strength steel, Precise Alloy, comprising the thin plate band of the superhigh precision of high duty metal and alloy, these products are widely used in electron trade, electrician trade, instrument manufacturing, machine industry, electromechanics trade and other relevant industries and field.
High speed development along with Chinese national economy, the demand rapid growth of cold rolled stainless steel band, silicon strip, Precise Alloy band, high temperature refractory alloy band, rare alloy band, high-precision cold rolling as thin as a wafer carbon element steel band and non-ferrous metal band, mill also will be rapidly developed and use widely.
Nineteen thirty, sieve grace was received first multi-roll mill patent, and this milling train is that tower rollers is the jaw type twelve high mill, and the patent of sieve grace was bought by Sen Dewei company and be in addition perfect afterwards, had obtained mill.Almost no longer made to the twentieth century this milling train eighties.Sen Dewei four column mills are grown up by former jaw type milling train, are the opening frame just because of this milling train, and up-down rollers system is very easy to produce, and causes the instability in the adjustment process, influences product quality, has increased accident rate.
It is integrally-built multiple rollers cold calender that Polish engineer's Sendzimir in 1932 has been invented frame, nineteen thirty-nine at U. S. application patent right, and set up Sendzimir company.To Mr. Sendzimir in 1958 seeking development of going abroad, with co-production 20 roller Sendzimir cold-rolling mills such as Japan, France, Germany, four layers of roll diameter of roller of 20 roller Sendzimir cold-rolling mills are 1:0.577:0.34:0.23,20 roller sendzimir mill shortcomings of this ratio are: 1, because the roller footpath is less, support memorial archway space is little, the metapyretic cooling effect of roll is poor, has limited the speed of milling train, has influenced the product precision; 2, design by English system, key dimension is three figure places behind the decimal point, makes that processing, adjustment and the operation of milling train are all very complicated; 3, ASU adjusts and has adopted double eccentric mechanism, has all used rolling bearing, has improved the difficulty of backing roll assembling, has limited the regulated quantity of ASU.
Summary of the invention
In view of this, the technical problem that mainly solves of the present invention is to provide a kind of high rigidity roll system structure that improves the rigidity of milling train and strengthen the mill of cooling effect.
For reaching above-mentioned technical problem, technical scheme of the present invention is achieved in that a kind of high rigidity roll system structure of mill, D
1=work roll diameter; D
2=the first intermediate calender rolls diameter; D
3=the second intermediate calender rolls diameter; D
4=back lining bearing diameter, the diameter ratio of described each roll satisfies following relationship: D
1: D
2=D
2: D
3=D
3: D
4=0.59～0.63.
Described work roll diameter is 58～75mm.
Described work roll diameter is 70mm.
The diameter ratio of described each roll is 0.618.
The technique effect that the present invention reaches is as follows: the roll system structure of mill of the present invention, the diameter ratio of each roll is 0.59～0.63, has adopted the roll system structure of above-mentioned value region, has improved the rigidity of milling train, and adopted the standard unit of metric system, be convenient to processing and guarantee machining accuracy.In addition, the diameter of each roller all greater than corresponding existing roller footpath, has strengthened the spacing between the roll, has increased the space, is convenient to lubricated and cooling.
Description of drawings
Fig. 1 is the schematic diagram of the high rigidity roll system structure of mill of the present invention.
Wherein, 1-working roll, the 2-first intermediate calender rolls 3-second intermediate calender rolls 4-back lining bearing.
The specific embodiment
As shown in Figure 1, be the high rigidity roll system structure of mill of the present invention, wherein, D
1Be working roll 1 diameter; D
2Be first intermediate calender rolls, 2 diameters; D
3Be second intermediate calender rolls, 3 diameters; D
4Be back lining bearing 4 diameters, the diameter ratio of above-mentioned each roll satisfies following relationship: D
1: D
2=D
2: D
3=D
3: D
4=0.59～0.63.Wherein, when the diameter of each roll is 0.618 than optimal values, when the diameter of working roll 1 is 58～75mm, just adopt Fibonacci number to dispose, roll system structure reaches maximum rigidity.During design, at first determine the working roll 1 of milling train or the diameter of back lining bearing 4, other roller diameter footpath all is configured in 0.59～0.63 ratio, thereby is designed to the mill of different-diameter series.Shown in figure, when back lining bearing 4 selected diameter to be the standard component of 300mm, the diameter of working roll 1 was chosen as 70mm, and first intermediate calender rolls 2, second intermediate calender rolls 3 can be selected 115mm, 185mm respectively according to the diameter ratio, and this moment, the rigidity of roll system structure was big.
Adopted the roll system structure of above-mentioned value region, all adopted the standard unit of metric system, compared, be convenient to processing and guarantee machining accuracy with English unit.In addition, the diameter of each roll has also increased the spacing of roll shop building all greater than existing respective series roller footpath when roller directly strengthens, strengthened the space, is convenient to lubricated and cooling.
The above is one of preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
