Disclosed is a rolling mill, in particular a rolling mill having more than one mill stand, comprising at least two rolls (30) which are mounted in a roll bearing in a mill stand to absorb rolling forces, further comprising means (40) for moving at least one roll relative to the mill stand as well as means (50) for determining the roll pass, the determining means having a pass reference (54) and a spatial reference (56) as well as means (58) for measuring the relative position between the pass reference and the spatial reference. In order to create a rolling mill that provides as accurate information as possible about the roll pass, the pass reference and/or the spatial reference is/are arranged peripherally in relation to the power flow occurring between the roll and the mill stand.
Rolling mill (1), particularly a multi-stand rolling mill (1), having at least two rolls (30) mounted in a roll stand (20), in a roll bearing (35), to absorb rolling forces, having means (40) for displacement of at least one roll (30) with reference to the roll stand (20), and having means (50) for determining the roll pass, wherein the determination means (50) have a pass reference (54) and a spatial reference (56), as well as means (58) for measuring the relative position between the pass reference (54) and the spatial reference (56), wherein the pass reference (54) and/or the spatial reference (56) is/are disposed peripheral to the force flow, with reference to a force flow that occurs between roll (30) and roll stand (20).
Rolling mill (1), particularly a multi-stand rolling mill (1), having at least two rolls (30) mounted in a roll stand (20), in a roll bearing (35), to absorb rolling forces, having means (40) for displacement of at least one roll (30) with reference to the roll stand (20), and having means (50) for determining the roll pass, wherein the determination means (50) have a pass reference (54) and a spatial reference (56), as well as means (58) for measuring the relative position between the pass reference (54) and the spatial reference (56), wherein the pass reference (54) is disposed at a distance from the roll bearing (35) of less than one bearing diameter of the roll bearing (35).
Rolling mill (1), particularly a multi-stand rolling mill (1), having at least two rolls (30) mounted in a roll stand (20), in a roll bearing (35), to absorb rolling forces, having means (40) for displacement of at least one roll (30) with reference to the roll stand (20), and having means (50) for determining the roll pass, wherein the determination means (50) have a pass reference (54) and a spatial reference (56), as well as means (58) for measuring the relative position between the pass reference (54) and the spatial reference (56), wherein at least one of the rolls (30) is mounted in a bearing body (70) and the pass reference (54) is disposed on the bearing body (70).
Rolling mill (1), particularly a multi-stand rolling mill (1), having at least two rolls (30) mounted in a roll stand (20), in a roll bearing (35), to absorb rolling forces, having means (40) for displacement of at least one roll (30) with reference to the roll stand (20), and having means (50) for determining the roll pass, wherein the determination means (50) have a pass reference (54) and a spatial reference (56), as well as means (58) for measuring the relative position between the pass reference (54) and the spatial reference (56), wherein the spatial reference (56) is disposed separate from the roll stand (20).
Rolling method in which rolls (30) are positioned on-line, to a desired roll pass, taking into consideration measurement results of means (50) for determining a roll pass, wherein the determination means (50) are calibrated off-line before rolling.
