Problems solved by technology

[0003] The high-speed wire rod mill has the characteristics of continuous, high-speed, torsion-free and controlled cooling production process, among which high-speed rolling is the most important process feature. Since high-speed rolling requires the pass to participate in deformation, the overall adaptability and versatility are poor. The requirements for parts are high, and the utilization rate of rolls is poor
Rolling with perforations consumes a lot of electricity, even-numbered stands use rolling guides that require oil-air lubrication, the utilization rate of the roll body is low, the scrap rate of the rolls is high, and the production of the rolls needs to be stopped for maintenance, which will increase the production cost and reduce the production efficiency

Embodiment Construction

[0011] The high-speed wire rod finish rolling process in this embodiment is rolled on a 28-pass finish rolling mill. The rolls of the rolling mills from 1 to 17 are arranged horizontally and vertically, and the rolls from 1 to 17 are rolled without holes. The roll gap of the rolls controls the following parameters, among which: the height of the rolled piece after the first pass is 102mm, and the four corners of the cross section are 128°; the height of the rolled piece after the second pass is 110mm, and the four corners of the cross section are 130°; The height of the piece is 87mm, and the four corners of the cross section are 134°; the height of the rolled piece after 4 passes is 94mm, and the four corners of the cross section are 132°; the height of the rolled piece after 5 passes is 70mm, and the four corners of the cross section are 129°; The height of the rolled piece is 74mm, and the four corners of the cross section are 136°; the height of the rolled piece after 7-pas...

Abstract

The invention discloses a high-speed wire finish-rolling process. Rolling is performed on 28 passes finishing mill 1-17 passes use the pass-free rolling way and the rolling piece is rolled between the two pass-free rollers and the height of the roll gap is the height of the rolling piece and the width of the rolling piece is the breadth of the freely spread rolling piece without gripping and deforming action of the pass sidewall. During rolling, it is only necessary to change the roll gap to adjust the section size of the rolling piece and the rolling adaptability is very strong, thereby optimizing the production process of the wire tandem mill, reducing the guide loss, reducing the oil gas lubrication consume, reducing the failure rate of the roller, increasing the use frequency of the roller and reducing the roller loss, improving the bite of the rolling piece, reducing the roll-changing number during rolling, in order to increase the productivity, save the energy, reduce the consume, ensure the production operate for long period. The high-speed wire finish-rolling process can be used in the same or similar rolling mill in civil with very wide application foreground.

Description

technical field [0001] The invention relates to a high-speed wire rolling process, in particular to a high-speed wire rod finish rolling process. Background technique [0002] High-speed wire rod refers to the wire rod that is rolled and formed by a high-speed rolling mill. It generally refers to hot-rolled round steel with a diameter of 5-16 mm or special-shaped steel with a corresponding cross-section. Common wire rods are mostly round sections, and special-shaped cross-section wire rods include oval and square And screw shape, etc., but the production quantity is very small. [0003] The high-speed wire rod mill has the characteristics of continuous, high-speed, torsion-free and controlled cooling production process, among which high-speed rolling is the most important process feature. Since high-speed rolling requires the pass to participate in deformation, the overall adaptability and versatility are poor. The parts requirements are high, and the roll utilization rate ...
