Production process for endless rolled wire rods and equipment thereof

Abstract

The invention discloses a production process for endless rolled wire rods and equipment thereof, and belongs to the technical field of metallurgy. The process the following steps: continuously castinga single-flow high-speed continuous casting blank, and controlling the continuous casting drawing speed at 2.8 m / min-10 m / min; performing continuous rolling deformation and temperature control cooling on the continuously cast high-speed continuous casting blank to form a single continuous straight finished product rolled piece, wherein the deformation speed of the casting blank is matched with the continuous casting drawing speed according to a same second flow principle; and segmenting, coiling and collecting the continuous straight finished product rolled piece as required. The equipment comprises a steelmaking continuous casting unit, a connecting unit, an intermediate rolling unit, a temperature control forming rolling unit, a coil separating unit and a finished product processing unit which are sequentially arranged. According to the process and the equipment, the capacity matching rolling of continuous casting and steel rolling can be realized, and the endless direct rolling canbe realized.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to an endless rolling wire rod production process and equipment thereof. Background technique [0002] In the existing wire rod production, due to the mismatch between the hourly output and production organization of continuous casting and rolling, the traditional solution is based on the single billet rolling method, that is, the continuous billet produced by the continuous casting machine is cut into a single billet for organizational production. The main disadvantages of these production methods are: (1) frequent biting during rolling, which is likely to cause production accidents; (2) frequent biting, easy to cause damage and impact to guides, rolling steel, and even equipment, and reduce service life; (3) Cutting the head and tail of the continuous casting billet needs to be cut during rolling, and the cutting loss is more than 1%, which reduces the yield; (4) Th...

AI Technical Summary

Problems solved by technology

This method achieves better output matching, eliminates the problem of secondary heating, and saves energy, but it cannot solve the problems of frequent biting of single rolling, head-to-tail temperature difference, etc.

[0006] In short, the current existing production methods are unable to better solve the problems of high output, high quality, low energy consumption, and low consumption in the wire rod production line.
