Definitions
- the invention relates to a method for rolling profiled rolling stock in roll stands with pairs of caliber rollers, the calibers of which are on both sides of start-up coils are limited.
- Running plates and mast rails are created in addition to the vertical ones axial rolling forces that, depending on the profile type and cross-sectional size, 1000 to 2000 can reach kN. These axial rolling forces may cause a shift between the rolls, and the resulting cross offset of the roll calibers leads to faulty profiles in the rolling stock.
- the invention is based, profiled these methods for rolling Rolled goods with caliber rolls whose caliber is bounded on both sides by start-up coils are to be improved in such a way that wear on the starting collars is essential reduced and the lubricant expenditure are significantly reduced.
- This object is achieved in that when using at least one caliber roller, which is axially position shiftable, this shift roller under defined Load with their investment areas against one and the other investment areas the other roller shifted, the stop positions, the length of the displacement path, the calculated center position of this displacement path is saved and the shift roller in one caliber aligned position to the other Roll is brought, and that the shift roller with its contact collar surfaces with incrementally defined loads against one and the other Contact surface of the other roller shifted, the values of the respective loads, the stop positions and the displacement paths saved and from these the course of the spring constants of the roll stand is calculated and saved and that the shift roller then out of its caliber-aligned position contrary to the axial forces to be expected during rolling the value of the spring constant and shifted during the Rolling is held in this position via position control devices.
- the method according to the invention brings the reduction in wear and lubricant savings, and so on very important advantage that the two caliber rollers during the Rolling process kept practically constantly in a caliber aligned position can be and thus lead to particularly good qualities of profile products, this is particularly the case when the rolling of these products involves turning of the profiled roller rod between the reversing stitches.
- the invention is based on the embodiment shown in the drawing explained in more detail.
- the roll stand consists of a drive side Roller stand WSA and an operator-side roller stand WSB.
- the operator-side roller stand WSB bearing chocks LBO and LBU and in the drive-side roller stand WSA bearing chocks LAO and LAU guided vertically and connected to adjusting devices AEO and AEU, respectively.
- the bearing chocks LBO and LAO are supported with their two pins ZO an upper caliber roller OKW and in the bearing chocks LBO and LBU with their pins CLOSE a lower caliber roller FM.
- Both OKW caliber rolls and FM are with adjacent calibers OKL and OKR or UKL and UKR.
- the operator-side pins ZO and ZU of the rollers have pin extensions ZVO or ZVU on which axial bearings AXO or AXU are located.
- the outer ring AR of the axial bearing AXU of the lower caliber roller FM sits in a cylinder piston ZK which is axially displaceable in a cylinder housing ZG, the via a pressure medium supply DMZ from a hydraulic control, not shown, can be loaded on both sides, can be moved in the direction of the double arrow PF is.
- FIG. 6 shows the measurement results stored with the aid of the control device controlled axial offset VZ, the lower caliber roller FM the caliber-aligned position, the expected rolling position Axial forces opposed, the effect of which should balance.
