Abstract
The invention relates to a roll stand for hot or cold rolling different rolled strips, comprising working rolls, support rolls and optionally intermediate rolls arranged in pairs. At least one pair of the rolls (6) is axially movable towards both sides and has a suitable shape to compensate for roll tolerances. Since each movable roll (6) has at least one hydrodynamic oil film bearing (3) on which a hydraulic unit (17) influencing the axial movement is integrated, roll errors due to the axial movement of the movable roll can be avoided.
Description
The present invention relates to a kind of mill stand that is used for hot rolling or the rolling band of cold rolling different materials, the intermediate calender rolls that it has working roll, the backing roll of paired setting and can select to use, roll in these rollers at least one pair of roll can move axially towards both sides, and has the suitable shape that can compensate the roll error.
A kind of mill stand that constitutes four-roller type or six-roll type support has been described among the EP-B0091540.In the four-high mill support, except working roll, backing roll also can produce relative to one another and move axially, and wherein backing roll or be independent of working roll and move separately perhaps moves with working roll.In the cluster mill support, the working roll that is provided with is supported on the backing roll that supports intermediate calender rolls, wherein working roll and/or backing roll and/or intermediate calender rolls can be movable relative to each other vertically, and at least two roll in the pair roller have crooked shape whole roller is long, this shape has constituted convex region and recessed district, wherein roll profile outside upper support or roll coefficient with it can only finish the locational to axial compensation that this roll is being determined.In the sliding bearing of this roll support in being inserted into insert.Have slidingsurface in the insert, bearing can produce relative slip with slidingsurface, or in the horizontal slip of mill stand, and can move axially with drive link.The required manufacturing expense of this structure is too high.
The objective of the invention is to make moving axially of roll in the mill stand to compare with the scheme with removable insert is simplified.
This purpose realizes in the following manner, that is, each movably roll have a fluid dynamic filmatic bearing at least, in described filmatic bearing, integrally be provided with the hydraulic mechanism that works to moving axially.Different with the slidingsurface of insert is, because the roll in fluid dynamic filmatic bearing floats on fluid dynamic oil film, so reduced axial rub.Therefore, can consume interference-free and gently make roll carry out axial location with very little energy.This integral hydraulic mechanism compares and can make very for a short time with at present common drive link, and can be used as the composition member of roll bearing.
Owing to have very little bearing friction, so can move forward axial location having under the situation of load.Because its requisite space is very little, so can use this hydraulic mechanism in all types of rolls (working roll, backing roll and intermediate calender rolls).
During hot rolling, backing roll is ground to form n-ter level facet.Backing roll moves in the front support of hot-strip mill row, so that the crown of the heat of compensation work roller in continous way is rolling particularly.Can realize preset by means of the CVC-working roll.
In the support of back, working roll mobile is used to regulate wearing and tearing and crown heat.The adjusting of roller gap shape realizes by roll is crooked.Backing roll moves in the support of back and has strengthened the regulatory region of roller gap shape preset, and is particularly suitable for elongated soft band and hard broadband.
When cold rolling, backing roll is ground to form the CVC-facet that is used to compensate the x2 error, so that the compensation plane error.Working roll in the six-roll type support or intermediate calender rolls have the CVC-facet that is used to compensate the xn error.
In the six-roll type support, backing roll has the CVC-facet that is used to compensate the x2 error, and intermediate calender rolls has the facet that is used to compensate the xn error, and working roll has the preventive structure that is used for compensating " marginal trough " phenomenon.
Therefore, hydraulic mechanism has the ring-type cylinder that is fixed on the mill stand, and the annular piston on the roll of being fixed on the sealing ring of an one is housed in the ring-type cylinder, and hydraulic cylinder can adapt to the shape of hydrodynamics filmatic bearing particularly well.The diameter of ring-type cylinder is only slightly greater than the bearing holder (housing, cover) diameter of hydrodynamics filmatic bearing.
Roll is moved on both direction.Bidirectional hydraulic by circular cylinder connects, and hydraulic oil will make annular piston alternately motion on two directions of motion.
But the effect of position sensor is each axial location of measuring the roll of axial adjustment.Can utilize the signal of position sensor to control these positions by means of hydraulic mechanism and the regulating circuit by mill stand.
Outstanding especially being also advantageous in that of the present invention can be used with hydraulic mechanism the hydrodynamics filmatic bearing as the parts of equipping again.Therefore, when equipment part again, old equipment can use existing insert.Just passable as long as change the hydrodynamics filmatic bearing like this.Saved travel mechanism required space on the mill stand support thus.
Further feature of the present invention will provide in the following description and accompanying drawing, and described accompanying drawing schematically illustrates one embodiment of the present of invention.
A unique accompanying drawing is represented the profile of vertically cutting open of longshore current body dynamics filmatic bearing, and the right-hand end position of described filmatic bearing is provided with hydraulic mechanism.There is shown a mill stand support (1) (or an insert), which is provided with the bearing shell (2) of hydrodynamics filmatic bearing (3).The neck bush (4) that belongs to filmatic bearing has formed at the roll pins having (5) of roll (6) goes up the conical sleeve that clamps usefulness.
On mill stand support (1), fix a circular cylinder (7), importing an annular piston (8) in the cylinder hermetically.Piston links to each other with roll pins having (5) by tapered roller bearing (9).The periphery of annular piston (8) is provided with sealing ring (10), and the sealing circle is arranged in the groove (11) of circular cylinder (7), and can move axially with annular piston (8).
Groove (11) is with annular piston (8) looping space (12), and separates by sealing ring (10).Part in the annular space (12) is by linking to each other with the hydraulic control device of mill stand outside the hydraulic pressure coupling part (13) that reaches separation.
The free end of roll pins having (5) by lid (14) oil seal cover.Be fixed with position sensor (15) on the lid, position sensor links to each other with the free end of roll pins having (5) by connecting rod (16).Circular cylinder (7), annular piston (8) and position sensor (15) have constituted hydraulic mechanism (17).
Device of the present invention has following function: when roll (6) need move axially, can be undertaken to the right by hydraulic oil or left hydraulic pressure connects according to the adjusting direction of hope.Hydraulic oil acts on the circle surface of sealing ring (10) for example, and produces axial force thus, frictionally is delivered on the roll pins having (5) of roll (6) above-mentioned power is low by tapered roller bearing (9).Moving axially by connecting rod (16) of roll pins having (5) is delivered to position sensor (15), and sensor is controlled the high pressure oil mass once more makes roll reach desirable position.
Device of the present invention provides a kind of simple, safety and space-saving axial moving device, thus since this device be complete closed do not need safeguard.And because the characteristic of this device is used its attachment device that also is suitable as in the existing mill stand insert.
