Abstract

The invention provides a combined three-roller continuous rolling mill. The combined three-roller continuous rolling mill comprises a plurality of three-roller rolling mills which are sequentially and alternately arranged at intervals; each of the three-roller rolling mills comprises a roller mandrel, convex blocks (19) are symmetrically arranged at the left side and right side of the roller mandrel; and the combined three-roller continuous rolling mill also comprises a side plate (5) arranged at the side of the roller mandrel (1), the side plate (5) is internally provided with guide rails (8) for supporting the convex blocks (19), and the bottom surfaces of the convex blocks (19) are supported on the guide rails.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a combined three-roller continuous rolling mill whose main function is to continuously roll pipes. Background technique [0002] The three-roll tandem mill is formed by at least two three-roll rolling mills arranged alternately and alternately. Each three-roll rolling mill is formed by three rolls to form a pass for rolling pipes. The radial planes of the three rolls form positive Y, inverted Y, or left Side Y, right Y type. Each three-roll rolling mill comprises: a roll core formed by three rolls, and a core frame for hanging the roll core is arranged every few roll cores. [0003] Both sides of the existing roll core are provided with protruding lugs, and the roll core is suspended on the side plate by means of suspension, and the side plates of every several three-roll rolling mills are installed on a core frame (such as the core On the base of the frame), the roll core is hung on ...
