Seating pinch roll in the process of production of steel plate impact: 1, if each pair of pinch roll, the roll axis is not parallel, transport in the pinch roll in the process of the steel plate will cause irregular sliding phenomenon of pinch roll, so that the plate appears irregular & other; Running deviation & throughout; 。 Therefore only guarantee each of pinch roll, the roll axis parallel, to ensure that the steel plate is not & other; Running deviation & throughout; 。 According to the relevant mills know, each of pinch roll, the roll center line parallel to O. 05 mm can satisfy the use. 2 on both sides, if the center line of the pinch roll is not parallel, are in fixed side and moving side transport pinch roll in the process of the steel plate can make the steel plate in one direction deviation, regularly so that the steel plate & other regularly; Running deviation & throughout; 。 Therefore only guarantee on both sides of the pinch roll axis parallel, to ensure that the steel plate is not & other; Running deviation & throughout; 。 According to the relevant mills know, on both sides of the pinch roll center line parallelism of 0. 05 mm can satisfy the use. 3, if the inlet side and outlet pinch roll axis is not parallel, is on the inlet side and outlet pinch roll transfer ship steel plate location plate will regularly to a direction deviation, so that the steel plate & other regularly; Running deviation & throughout; 。 Only guarantee the entry point for this and outlet pinch roll axis parallel, to ensure that the steel plate is not & other; Running deviation & throughout; 。 According to the relevant mills know, inlet side and outlet of the center line of the pinch roll parallel to O. 05 mm can satisfy the use. 4, if the pinch roll diameter, on both sides are in the process of transport pinch roll steel plate can make the steel plate in one direction deviation, regularly so that the steel plate & other regularly; Running deviation & throughout; 。 Therefore only guarantee on both sides of the pinch roll diameter is consistent, to ensure that the steel plate & not other Running deviation & throughout; 。 According to the relevant mills know, on both sides of the pinch roll adopts with grinding is better. 5, if the center line of the pinch roll, perpendicular to the line of shear blade does not transport in the pinch roll in the process of the steel plate can make the steel plate regularly to a direction deviation, so that the steel plate & other regularly; Running deviation & throughout; 。 Therefore only assure the center line of the pinch roll and vertical shear blade line, to ensure that the steel plate & not other Running deviation & throughout; 。 According to the relevant mills know, pinch roll center line and the line of shear blade verticality of 0. 1 mm can satisfy the use.
