Problems solved by technology

[0003] The occurrence of guide damage caused by steel rolling not only affects the rolling rhythm, but also destroys the frame material.
The wear and damage of the guides have always been an important factor restricting the stability of the process line. The damage of the guides not only causes the steel to be held back, but also easily produces quality defects such as ears and folds, which affects the yield of finished products.

Embodiment Construction

[0023] The present invention judges whether the guide will be damaged by using the change of the rolling mill load current of the stand where the guide guard is located and the change of the rolling mill load current of the adjacent stand. Specifically, after the low-tension rolling of intermediate rolling and the tension-free rolling of pre-finishing are realized through manual joint adjustment (looper control is tension-free rolling), the load current value of the mill stand after the start of rolling is stabilized is The reference current value, by observing the change of the real-time current value of the rack mill and the current value of the front mill, and comparing the real-time current value of the rack mill and the current value of the front mill with the reference current value, the rolling guide position can be judged online status.

[0024] In production practice, guides and auxiliary process components often have subtle signs before damage, which we have analyzed...

Abstract

The invention discloses a method for judging whether a rolling guide position of a high-speed wire production line is damaged or not. The method is adopted to judge whether the guide position is about to be damaged or not according to change of load current of a rolling mill of a machine frame where the guide position is located and change of load current of rolling mills of adjacent machine frames. The method can be used for guiding steel rolling production and avoiding a stuck steel accident and a quality accident caused by the managed rolling guide position.

Description

technical field [0001] The invention relates to a steel rolling technology, in particular to a method for judging the damage of the rolling guide position of a high-wire production line. Background technique [0002] The tension control of the high-line production line is mainly carried out by the operator of the main console. By observing the change of the motor load current, the tension change can be found in time, and necessary measures can be taken to ensure the tension is stable, and some accident signs can be warned to avoid accidents. [0003] The occurrence of guide damage caused by steel rolling not only affects the rolling rhythm, but also destroys the frame material. The wear and damage of guides has always been an important factor restricting the stability of the process line. The damage of guides not only causes steel to be held back, but also easily produces quality defects such as ears and folds, which affects the yield of finished products. Contents of the ...
