Problems solved by technology

[0003] At present, the application of this technology has a low degree of automation, and many processes are manually operated, and the accuracy and efficiency are severely limited. In fact, only the fluctuation compensation is performed on the end area.
At the same time, in the current rail length fluctuation compensation control technology, which part of the rail length is compensated and how much is to be compensated is manually extracted and entered without programming. High flexibility, it is very easy to judge the wrong adjustment position manually, so that the adjustment position accuracy is low, the adjustment amount fluctuates greatly, the adaptability is poor, the robustness is low, and there is no self-learning ability

Embodiment

[0048] The present invention will be further described below by taking the height fluctuation compensation of a 100-meter rail as an example.

[0049] The embodiment provides a rail specification full length fluctuation compensation system, the system includes a thermal profiler, a model system and a primary control system; wherein the thermal profiler is mainly responsible for the generation of height data; the model system is mainly responsible for the establishment of the fluctuation model , including searching for compensation points and fluctuation compensation curves; the primary control system is sequential control, which is responsible for issuing fluctuation commands. Each part of the system of the embodiment will be described in detail below through the workflow of the embodiment.

[0050] 1. Raw data acquisition

[0051] The thermal profiler is based on the FTP file transfer protocol. When the thermal profiler generates a new height record, it will be exported and ...

Abstract

The invention relates to the steel rolling production field and discloses a rail specification full-length fluctuation compensation system, which is used for automatically searching a rail specification compensation point and generating a fluctuation compensation curve to automatically complete the fluctuation compensation. The invention comprises a hot-state profilometer, a model system and a first-level control system. The model system comprises a compensation point search module and a compensation curve generation module, wherein, the hot-state profilometer is used for acquiring specification data in the length direction of the rail; the compensation point search module is used for searching out the compensation point from the specification data in the length direction of the rail; thecompensation curve generation module is used for generating a fluctuation compensation curve of the rail specification in the length direction according to the compensation point searched by the compensation point search module; the primary control system is used for controlling the compensation mechanism to compensate the fluctuation according to the fluctuation compensation curve. The inventionis applicable to the height specification fluctuation compensation control of rails.

Description

technical field [0001] The invention relates to the field of steel rolling production, in particular to a compensation system for rail specification fluctuations in length. Background technique [0002] Compensation technology for rail specification general length fluctuation, by analyzing the section lengths of different varieties, the height difference and the frame to be compensated, adopts the segmental control method of directly performing a large reduction on the first-level automatic control system to completely eliminate the cross-section. Long and large fluctuations. [0003] At present, the application of this technology has a low degree of automation, and many processes are manually operated, and the accuracy and efficiency are severely limited. In fact, only the fluctuation compensation is performed on the end area. At the same time, in the current rail length fluctuation compensation control technology, which part of the rail length is compensated and how much ...
