Example Embodiment

[0081] Hereinafter, a positioning feedback device and a positioning feedback control method for a multi-roll mill work roll of the present invention will be further described in detail based on the drawings and specific embodiments of the specification.

[0082] Such as figure 1 , 2 The positioning feedback device of the work roll of a multi-roll mill is used for the positioning adjustment of the roll system after roll change and before the roll test, so as to achieve effective support for the roll system, including: the centerline of the stand is up and down, front and back Four identical mechanisms are arranged in mirror symmetry, each of which includes:

[0083] The transition plate (1) set on the frame,

[0084] The fixed arm (2) detachably fixed on the transition plate,

[0085] The linear guide (3) opened on the transition plate,

[0086] The traverse arm (4) set in the linear guide,

[0087] The traverse oil cylinders (5) arranged at both ends of the fixed arm are used to drive t...

Abstract

The invention discloses a position feedback device for a working roller of a multi-roller mill and a position feedback control method of the position feedback device. A control system is matched with the corresponding position feedback device to perform position adjustment control on a roller system after a roller is replaced and before a roller leaning test is performed, so that effective support for the roller system is realized; transverse movement oil cylinders drive transverse movement arms to move along linear guide rails to reach initial set positions; rotating oil cylinders drive rotating arms to reach mechanical zero positions; position sensors are matched with the control system and the transverse movement oil cylinders to enable the transverse movement arms to reach positions where the transverse movement arms are in no-clearance surface contact with the rotating arms; and load sensors are matched with the control system and adjustment devices which are arranged at the central line positions of fixed arms and are used for adjusting the transverse movement arms so as to drive the transverse movement arms, the rotating arms and side supporting roller boxes to achieve the effect that a set value of a load difference between two sides can be met. The position feedback device for the working roller of the multi-roller mill and the position feedback control method of the position feedback device are high in load-deflection resistance, the stability of the roller system is high, and the surface quality of a rolled strip is high; and the stability of the rolling working condition and the rolling continuity are guaranteed.

Description

technical field [0001] The invention belongs to the rolling field of continuous rolling mills, and in particular relates to a positioning feedback device and a positioning feedback control method for working rolls of a multi-roll rolling mill. Background technique [0002] The carbon steel strip continuous rolling mill usually adopts six-roll configuration, including backup rolls, intermediate rolls and work rolls. Due to the physical characteristics of carbon steel, the roll diameter of the work rolls is usually relatively large, generally above 250mm, which can not only meet the reduction rate requirements , and the roll diameter and length ratio of the work roll can fully meet the requirements. [0003] Stainless steel is characterized by high deformation resistance, which is generally twice as high as that of ordinary carbon steel; due to the formation of deformed martensite during cold working, the work hardening rate is fast, and greater rolling capacity and load are r...
