Abstract

The invention provides a roller assembly for rolling double-tooth track steel and a rolling mill. The roller assembly for rolling double-tooth track steel comprises an upper roller, a lower roller, a left roller and a right roller, the left roller is provided with a left forming surface, the right roller is provided with a right forming surface, the upper roller is provided with an upper forming surface, and the lower roller is provided with a lower forming surface; the left forming face, the right forming face, the upper forming face and the lower forming face jointly define a rolling channel; the upper roller and the lower roller can move in the vertical direction; and the left roller and the right roller can move in the left-right direction. The roller assembly can be applied to double-tooth track steel with similar shapes but different sizes, and when the cavity wall of the rolling channel is abraded, online compensation can be realized without stopping production and disassembling the roller, so that the production efficiency is ensured, and the purchase cost of the roller is saved.

Description

technical field [0001] The invention belongs to the technical field of hot-rolled section steel, and in particular relates to a roll assembly and a rolling mill for rolling double-tooth crawler steel. Background technique [0002] At present, the rolling process commonly used for special-shaped steel is: using rectangular billets or square billets to pass through multiple box holes, cutting holes, control holes and finished holes, and finally rolling them into special-shaped steel of the target shape. Track steel is a kind of special-shaped steel. Track steel is often used to make track chains of construction machinery such as excavators, bulldozers, crawler cranes, and pavers. Track steel is divided into single-tooth track steel, double-tooth track steel and three-tooth track steel according to its shape. Relatively speaking, the double-tooth track steel has higher teeth, has a longer service life, better structural form and grip performance. [0003] Track steel is gener...
