Hot rolling ultrafast cooling process control system

Abstract

The invention provides a hot rolling ultrafast cooling process control system. The hot rolling ultrafast cooling process control system comprises a basic material and boundary heat transfer module, a presetting calculation module, a cooling information module, a feed-forward compensation module, a feedback control module, a steel board information tracking module, a data analysis module and a self-adaption and strip steel position tracking module. The basic material and boundary heat transfer module is used for amending and setting calculation and calculating the tube nest configuration needing to be changed due to the variation; the presetting calculation module is used for calculating the temperature drop after strip steel is subjected to ultrafast cooling and the water spraying configuration when the strip steel reaches a coiling thermometer and reaches the target coiling temperature; the cooling information module is used for processing the information transmitted by the presetting calculation module; the feed-forward compensation module and the feedback control module are used for dynamically adjusting a tube nest used for feedback in an ultrafast cooling area and a tube nest used for feedback in a laminar cooling area; the steel board information tracking module is used for collecting various most direct data of a hot rolling production line; the data analysis module is used for analyzing data adjustment; and the self-adaption and strip steel position tracking module is used for self-learning adjustment setting. The production process is stable, the control precision is high, and the control requirements of the field process are met.

Description

technical field [0001] The invention relates to the field of ultra-fast cooling process control of hot-rolled strip steel, in particular to a hot-rolled ultra-fast cooling process control system. Background technique [0002] In recent years, with the rapid development of the national economy, the output of hot-rolled strip steel has increased, and the requirements for its comprehensive performance have gradually increased. With the development and application of a variety of new steel types, more precise cooling control of the strip steel on the hot output roller table is required, not only to ensure the accuracy of the coiling temperature, but more importantly, to ensure the accuracy of the ultra-fast cooling outlet temperature , to realize the control of the internal organizational structure of the strip steel, and then realize the upgrading of steel grades or the development and application of new steel grades. [0003] Controlled rolling and controlled cooling is an ad...
