Eight slanting rollers shape structure of rolling mill of eight slanting rollers

Abstract

The invention discloses a biased-eight-roll roll shape structure, which comprises the following parts: upper and lower bearing rolls, upper and lower working roll, upper and lower middle roll, upper and lower lateral support roll, wherein the upper and lower working roll and upper and lower lateral bearing roll are attached on the inner side of upper and lower bearing roll, the middle roll is set between working roll and lateral bearing roll, the center of working roll deviates the central line of bearing roll by 6-8% as bearing roll diameter, the roll radius and breadth of working roll, bearing roll, lateral bearing roll, middle roll adopts specific parameter.

Description

Technical field: [0001] The invention relates to a cold rolling mill. Background technique: [0002] The partial eight-high rolling mill is a cold rolling mill with small-diameter work rolls and a unique structure. In fact, it is a multi-roll mill in which side support rolls are added to the work rolls on the four-high rolling mill driven by the back-up rolls. [0003] From the perspective of mechanism structure, the partial eight-high rolling mill and the four-high rolling mill are basically the same. The unique structure of the partial eight-high rolling mill is that the working roll has a side support roll system and is installed off the center line of the support roll. During rolling, the work rolls are supported by the upper and lower backup rolls in the vertical direction, and supported by the side support system in the lateral direction. The side support rollers and middle rollers are assembled with fixed bows, and then fixed on the side support roller bearing housin...

Problems solved by technology

[0008] Although this kind of partial eight-high rolling mill has many advantages mentioned above, if the roll diameter, roll width of the work roll, backup roll, side backup roll, intermediate roll and the deviation of the work roll from the center line of the backup roll are improperly selected, it will directly affect the partial eight-high rolling mill. The normal operation of the rolling mill, such as the occurrence of unstable phenomena such as jumping
