Embodiment Construction

[0071] The specific implementation of the combined two-roll tandem rolling mill of the present invention will be further described below in conjunction with the accompanying drawings.

[0072] Existing horizontal rolling mill and vertical rolling mill respectively comprise: rolling stand, two rolls that are arranged in parallel with each other in the rolling stand, roll chock, roll balance mechanism 10, the roll gap adjusting mechanism that adjusts roll gap and roll changing mechanism. In order to minimize the overall length of the combined two-roll mill of the present invention along the rolling line A-A, the combined two-roll mill of the present invention is to alternate the horizontal rolling mill and the vertical rolling mill of the prior art. It is installed on the base of the same frame structure to form a combined continuous rolling mill.

[0073] see figure 1 , the combined two-roll tandem rolling mill of the present invention comprises a rolling mill base 5, on whic...

Abstract

The invention relates to a combined two-roller continuous mill, which comprises at least one horizontal rolling assembly (71), at least one vertical rolling assembly (72) and a roll changing mechanism, wherein rolling assembly frames are alternately and continuously attached along a rolling line (A-A) and are arranged on a base 5 in 90 degrees; each rolling assembly (71) comprises a floating frame (11) which is embedded in the rolling assembly frame; two rollers and a roller bearing seat are arranged in the floating frame; a roller gap adjusting mechanism is arranged on an upper roller bearing seat (4) or on an end plate (14) of the floating frame (11) corresponding to a roller bearing seat(65) at the transmission side; and a roller gap centering mechanism which is arranged on a movable top cover (6) is further added. The rolling assembly frames are compactly arranged in a gapless way, when the gap between two rollers is adjusted by the roller gap adjusting mechanism and the roller gap centering mechanism, the gap between the two rollers is automatically centered; and the continuous mill is high in operating rate.

Description

technical field [0001] The invention relates to a two-roller continuous rolling mill, in particular to a combined two-roller continuous rolling mill which is alternately arranged horizontally and vertically and can continuously roll pipes, rods and profiles. Background technique [0002] Existing tandem rolling mills are arranged alternately by horizontal rolling mills and vertical rolling mills, and their rolling lines are on the same straight line A-A. Generally speaking, the rolling stands of the horizontal rolling mill and the vertical rolling mill each include: a cuboid with a cavity, and windows are opened on the four rectangular walls of the cavity cuboid to form a cuboid hollow frame; The two rolls are respectively installed in parallel in the cavity of the rolling stand through the roll chocks. The two horizontal roll chocks of the horizontal rolling mill can move vertically on the inner wall of the window of the rolling stand, and the two vertical roll chocks of t...
