Description
Technical Field
The invention relates to medium plate production equipment, in particular to a medium plate mill guide device and a lip position monitoring device and method thereof.
Background
The heavy and medium plate rolling mill is a key device in a heavy and medium plate production line, and the guide and guard device is arranged at the inlet side and the outlet side of the rolling mill and is used for smoothly leading a steel plate into and out of the inlet of the rolling mill in the forward pass rolling and smoothly leading the steel plate into and out of the outlet of the rolling mill in the reverse pass rolling. The installation level of the rolling mill guide and guard device has important influence on the yield of the rolling mill, the specification and the variety of plates and the rolling quality of medium and thick plates.
Referring to fig. 1, the rolling mill guide and guard device in the prior art comprises a guide and guard device main body 8, an upper support roll 9, an upper working roll 10 attached to the upper support roll 9, a lower support roll 11, and a lower working roll 12 attached to the lower support roll 11, wherein the guide and guard device main body 8 is further provided with a guide and guard oil cylinder 1, a working roll cooling manifold 2, a smoke suppression manifold 3, a support roll cooling manifold 4, a rolling mill high-pressure water descaling manifold 5, a guide and guard device lip 6 and a working roll water cutting plate 7. The lip 6 of the guide device is tightly attached to a working roll water cutting plate 7 arranged on a bearing seat of the working roll to guide a rolled steel plate 13.
When the roll of the rolling mill is changed, the working rolls 10 and 12 are not completely attached to the supporting rolls 9 and 11 when the upper bending cylinder is lifted. During calibration, the gap between the working rolls 10 and 12 and the supporting rolls 9 and 11 is eliminated under the action of the calibration force, so that the position of the lip 6 of the guide device below the position of the water cutting plate 7 of the working rolls is opposite to that of the lip 6 of the guide device, and the head defect of the rolled steel plate 13 is caused by the fact that the rolled steel plate 13 tilts and impacts the lip 6 of the guide device in the production process; particularly, in the case of rolling a thick steel plate, the rolled steel plate 13 collides with the guide and guard device lip 6 below the position of the guide and guard device lip 6 relative to the work roll water cutting plate 7 due to the excessive head warping of the rolled steel plate 13, so that the rolling mill guide and guard device is broken. When the position of the lip 6 of the guide and guard device relative to the lower part of the water cutting plate 7 of the working roll is found in the production process, the lifting force of the guide and guard oil cylinder 1 needs to be increased temporarily, but the secondary problem is that the middle part of the water cutting plate 7 of the working roll is increased in deformation to scratch the working rolls 10 and 12, so that the upper surface of a rolled steel plate 13 has indentations.
