Embodiment Construction

[0020] A method for aligning the rolling line center of a high-speed wire rod finishing mill, which includes:

[0021] (1) Calibrate the middle reference point: set two central reference points before and after the calibration machine according to the original installation reference line, and the two reference points coincide with the equipment installation center line;

[0022] (2) The placement of the emitter: it includes the fixed tooling of the laser emitter to ensure that the deviation between the laser center of the laser emitter and the center of the entire rolling line is controlled at the millimeter level, and fine-tuning is performed to establish a laser line approximately parallel to the rolling center creating condition;

[0023] (3) Establishment of the laser collimation line: firstly, select the reference point as the measurement reference, take the original installation reference or the feature point of the online equipment as the reference, that is, use the cen...

Abstract

The invention relates to a high-speed wire stock finishing mill, in particular to a center-aligning method of a high-speed wire stock finishing mill, wherein the method comprises the following steps: (1), calibrating a middle datum point; (2), placing a transmitter; (3), establishing a laser collimating line; (4), measuring the point location and arranging a laser receiver on different measuring points to calibrate the central deviation of point location, wherein each point location is measured for twice, and the average value of the measuring result is used as the final result.

Description

technical field [0001] The invention relates to a high-speed wire rod finishing mill, in particular to a centering method for a high-speed wire rod finishing mill. Background technique [0002] Wire rod is one of the important rolling products. It occupies a particularly important position in the national economy. Because it is delivered in the form of coils, it is also called wire rod. The wire rod is characterized by being thin and long, so the dimensional accuracy and uniform control of the cross-section and length during the rolling process are extremely important. [0003] According to the requirements of the production process, a set of rolling mill is generally divided into several continuous rolling units, and there is no continuous rolling relationship between each unit. It is generally divided into rough rolling unit, intermediate rolling unit and finishing rolling unit. When the maximum rolling speed of the wire rod mill is higher than 40m / s, it is called a high...
