Two roller upright rolling mill

Abstract

The invention relates to a two roller upright rolling mill, which comprises a rolling mill base, a floating rack (11) installed on a horizontal beam (5-2) of the rolling mill base and a mill roller clearance regulating mechanism, wherein a roll-gap alignment device includes a vertical end plate (5-1) on the rolling mill base (5) or a movable top cover (6) on the end of the horizontal beam (5-2); and a hydraulic drive mechanism having a shift sensor (7) or a mechanical drive mechanism having a coder installed on the top cover (6). The mill roller clearance regulating mechanism has the hydraulic drive mechanism of the shift sensor (7) and the mechanical drive mechanism having the coder connected to the floating rack (11). During the two mill roller clearance regulation, the roll-gap of the two rollers can be automatically aligned. The device is simple. It is convenient for operation and maintenance. The roller-exchange operation is convenient and fast.

Description

Technical field [0001] The invention relates to a two-high rolling mill, in particular to a two-high vertical rolling mill capable of rolling rectangular steel, pipes, bars and profiles. Background technique [0002] The two-high vertical rolling mill includes: a rolling mill base and a rolling mill stand fixed on the rolling mill base, two vertical rolls installed in the rolling mill stand parallel to each other, a roll balance mechanism, and a roll gap adjustment mechanism installed on the rolling mill stand . Among them: the rolling mill base is installed on the foundation; the rolling mill stand is a cuboid with a cavity, and windows are opened on the four rectangular walls of the cavity cuboid to form a rectangular hollow frame; two vertical rolls pass through the rolls respectively The bearing seat is relative to the rolling centerline FF (see Figure 8 ) It is installed vertically and parallel in the cavity of the rolling mill stand, and the roll chock can be adjusted hori...

Problems solved by technology

However, since the roll transmission mechanism is located under the rolling mill stand, the motor and the attached cable pipelines of the transmission mechanism are soaked and washed with scale and rolling cooling water, and even due to the accumulation of scale around the rolling mill, The working environment of the lower part of the rolling mill stand is harsh and inconvenient for inspection and maintenance, which leads to a decrease in production operation rate and an increase in maintenance costs
