Two roller upright rolling mill

Abstract

The invention relates to a two roller upright rolling mill, which comprises a rolling mill base, a rolling mill rack, two upright mill rollers (3, 2) and a mill roller clearance regulating mechanism, wherein the two upright mill rollers (3, 2) are arranged inside the rolling mill rack in parallel; the rolling mill base (5) comprises an upright end plate (5-1) and horizontal transverse beams (5-2) which are connected with four angles of the upright end plate (5-1) respectively; the horizontal transverse beams (5-2) are vertical to the upright end plate and extend towards the same direction; the rolling mill base is a floating type rack (11) which is embedded among the four horizontal transverse beams of the rolling mill base; the mill roller clearance regulating mechanism is arranged at the transmission side or the operation side of the rolling mill; and a roller gap centering mechanism is also arranged at the same side with the mill roller clearance regulating mechanism. While the two mill rollers are subjected to clearance regulation, the roller gap between the two mill rollers is centered automatically; the device is simple and convenient to operate and maintain; and the rollers can be exchanged conveniently and rapidly.

Description

technical field [0001] The invention relates to a two-roller mill, in particular to a two-roller vertical 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 frame fixed on the rolling mill base, two vertical rolls installed in the rolling mill frame parallel to each other, a roll balance mechanism and a roll gap adjustment mechanism installed on the rolling mill frame . 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 cuboid hollow frame; two vertical rolls pass through the rolls respectively The housing is relative to the rolling center line F-F (see Figure 8 ) are vertically and parallelly installed in the cavity of the rolling mill stand, and the roll chock can be adjusted for horizontal disp...

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
