Abstract

An assembled two-high rolling mill, which belongs to the field of two-high rolling mill technology, is used for overcoming the disadvantages of heavy and huge structure and small application range of prior two-high rolling mill. The scheme consists of a housing frame, an upper roller and a lower roller. After improvement, the housing frame is changed into an assembled frame consisting of an upper and a lower crossbeams and pillars, wherein an upper and a lower rotating discs are respectively arranged on the upper and the lower crossbeams; and the upper roller is hung on the upper rotating disc and the lower roller is arranged on the lower rotating disc to eliminate the disadvantage of huge and heavy structure of the integral cast iron housing frame, thus greatly facilitating the replacement of the upper and the lower rollers and the adjustment of the roller seam. The upper and the lower rollers can deflect opposite to each other through the rotation of the upper and the lower rotating discs to achieve rolling of a plurality of products, thus greatly enlarging the application range of the two-high rolling mill. The assembled two-high rolling mill is suitable for rolling products of different shapes.

Description

technical field [0001] The invention relates to a two-roll rolling mill, in particular to a two-roll rolling mill capable of adapting to rolling products of various shapes, and belongs to the technical field of two-roll rolling mills. Background technique [0002] The traditional two-roll rolling mill consists of archway frames, upper and lower rolls, etc. The archway frames are cast iron castings, which are bulky and heavy in structure, difficult to install, disassemble and maintain, and have high consumables and high overall costs; in addition, the upper and lower rolls with fixed positions It is very inconvenient to load and unload, time-consuming and troublesome to replace, and cannot adapt to the use requirements of rolled products of different shapes, resulting in a single shape of rolled products and a narrow scope of application. Contents of the invention [0003] The object of the present invention is to provide an assembled two-roll rolling mill to overcome the d...
