Abstract

The invention provides a vertical roll mill capable of vertically shifting a roll. The mill comprises a mill body and a lifting device which is enclosed by a pedestal and four upright posts, wherein a lifting hydraulic cylinder is fixedly connected above each upright post; a jacking nut, an isolating sleeve and a locking nut are sleeved on the top of a piston rod of each lifting hydraulic cylinder in sequence; the pedestal is also provided with an elevation adjusting mechanism; the lifting hydraulic cylinders are arranged on the guide posts of the pedestal; and a stand of the mill body adjusts the vertical roll mill body through the lifting hydraulic cylinders and the elevation adjusting mechanism to realize adjustment of a working face of the roll. In terms of the structure, vertical shifting of the roll is realized by integrally lifting the vertical roll mill, the service life of the roll is prolonged, a roll porous mechanism is additionally arranged, and on-line replacement of product specification can be realized. The vertical roll mill and the lifting device can be simultaneously pulled out during roll replacement; the lifting device can be simultaneously applied to replacing the roll by pulling out a steel wire of the vertical roll mill body and replacing the roll by pushing a hydraulic cylinder out; and an operating side and a transmission side of the vertical roll body do not need to be differentiated during assembly.

Description

technical field

[0001] The invention relates to a rolling mill equipment, in particular to a vertical rolling mill capable of realizing roll shifting up and down. Background technique

[0002] In recent years, with the rapid development of my country's economy, people's consumption level has been continuously improved, which has greatly promoted the vigorous development of civil construction, automobile and other industries. The government has also spared no effort to increase investment in infrastructure. As an upstream beneficiary industry, the iron and steel industry has been greatly developed, but at the same time it has put forward higher requirements on the production efficiency of the industry, and in order to reduce energy consumption and save costs, it has been put at the top of the list. In the traditional vertical roll mill, the roll pair is fixed in the mill frame and can only move left and right and cannot be lifted up and down. During the rolling process, only...

Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the vertical roll rolling mill that can shift up and down of the present invention and the use process are described:

[0024] like Image 6 As shown, the structure of the vertical roller mill body described in the present invention is basically the same as that of the traditional vertical roller mill, and is mainly composed of a rolling mill frame 6, a vertical roller system 7 and a pressure measuring device 8. In this embodiment, only two vertical rollers are used. The vertical roller system composed as an example, but not limited thereto.

[0025] like Figure 4 , Figure 5 As shown, the vertical rolling mill body is installed in the frame composed of the base of the lifting device, four columns and the lifting hydraulic cylinders on the columns. The piston rod of each lifting hydraulic cylinder is covered with a jacking nut 3, a spacer 4 and lock nut 2, four trunnions 12 are provided on the corresponding columns of ...
