Embodiment Construction

[0023] A method for controlling the general dimensional uniformity of finished rods and wires provided by an embodiment of the present invention includes the following steps:

[0024] Step S1, when the production line is a bar mill production line, the last two rolling stands of the roughing group of the bar rolling production line adopt the ellipse-transformed elliptical pass system, and the last two rolling stands of the middle rolling group of the bar mill production line adopt the metamorphic circular pass system. - Round hole type system.

[0025] Step S2, when the production line is a high-speed wire-rod mill production line or a high-bar mill production line, the last two stands of the rough-rolling unit of the high-speed wire-rod mill production line or the high-bar mill production line adopt the elliptical-abnormal elliptical pass system, and the high-speed wire mill production line or the high-bar mill production line The last two rolling mills of the middle rolling ...

Abstract

The invention discloses a control method for the general size uniformity of rod and wire finished products, and belongs to the technical field of steel rolling processes. The control method for the general size uniformity of the rod and wire finished products comprises the steps that when a production line is a rod rolling mill production line, the last two rolling mills of a roughing rolling mill set of the rod rolling mill production line adopt an ellipse-distorted ellipse hole pattern system, and the last two rolling mills of an intermediate rolling mill set of the rod rolling mill production line adopt a distorted round-round hole pattern system. According to the control method for the general size uniformity of the rod and wire finished product, the uniformity of supplied materials before finish rolling of the finished product can be guaranteed, and the general size uniformity of the rod and wire finished product is improved.

Description

technical field [0001] The invention relates to the technical field of steel rolling technology, in particular to a method for controlling the uniformity of size of finished rods and wires. Background technique [0002] Modern rod and wire rolling mills generally adopt a serial and fully continuous arrangement. In order to avoid quality defects caused by the torsion of the rolled piece during the rolling process, an alternate horizontal and vertical arrangement is generally adopted. The pass system generally adopts an ellipse-round pass system (generally horizontal The rolling mill adopts elliptical pass, and the vertical rolling mill adopts round pass), this pass system can ensure smooth and uniform deformation during the rolling process, and the product quality is better. [0003] In the rolling process, the front pass of the rough and medium rolling unit is relatively large, and generally no looper is set. In order to ensure the smooth rolling process, micro-tension rolli...
