Problems solved by technology

Under this compact layout requirement, if the vertical roll mill adopts the bottom drive type, there is no problem in realizing the compact layout of the multi-stand reversible continuous rolling mill, but the bottom drive vertical roll mill is not accepted by most users due to difficult maintenance; The traditional upper drive vertical roll mill, because the stand spacing is very tight, the vertical roll change cannot be achieved by the traditional roll change method (unless the stand spacing is increased)

Abstract

The invention discloses a novel upper-transmission vertical roller mill which comprises a base, wherein a vertical roller rack is arranged on the base; a vertical roller assembly is mounted on the vertical roller rack; a transmission bracket is arranged above the vertical roller assembly and located at the tops of stands of adjacent two apparatuses so as to support a transmission motor and a speed reducer; the transmission motor and the speed reducer are in transmission connection with the vertical roller through a universal coupling shaft; a separation mechanism is arranged between two universal coupling shafts below the speed reducer so as to separate the universal coupling shafts from the vertical roller; and the vertical roller rack is also provided with a side moving mechanism for the vertical roller to move along the two sides of the rack. The vertical roller mill disclosed by the invention can realize compact arrangement and quick roller change on the premise of adopting an upper-transmission vertical roller mill for multi-rack reversible tandem rolling; and the invention also discloses a novel mill arrangement mode and a roller changing method.

Description

technical field [0001] The invention relates to the technical field of rolling, in particular to an upper-drive vertical roll mill, and also relates to a more efficient rolling mill layout and a roll-changing method for the vertical roll mill. Background technique [0002] Vertical roll mills for medium and thick plates, steckel mills, hot continuous rolling and (or) flat steel engineering are used for rolling in the width direction of slabs, and the roll transmission types are divided into two types: upper transmission and lower transmission. The transmission device of the upper drive vertical roll mill is placed above the vertical roll frame, and the roll is driven by a vertically arranged universal joint shaft; the upper drive vertical roll mill has two types of roll change: fixed frame and frame moved out. The specific roll change The process is as follows: [0003] 1. The roller changing method of the frame-fixed upper transmission: [0004] 1. Move the roll assembly ...
