Continuous casting billet cutting control system and control method thereof

Abstract

The invention discloses a continuous casting billet cutting control system and a control method thereof. By utilizing the data, such as a sheet hot rolling outgoing direction long billet command, a thick plate rolling machine outgoing direction short billet command and a heat pouring process tracking signal, an optimized cutting method which is compatible with two outgoing direction command specifications and is used for a long billet in a scope of a casting machine is provided to control a continuous casting online cutting machine to perform online one-time cutting, so that aims of reducing cutting loss, and supporting hot rolling and thick plate outgoing direction heat -CAST pouring are achieved; and therefore, the maximization and the optimization of the efficiency of the casting machine are ensured. The continuous casting billet cutting control system is friendly to a user interface and consistent in interface; and calculating results of two types of outgoing direction models canbe seen in a picture by an operator without switching between two pictures, so that the operation interface friendliness is improved.

Description

technical field [0001] The invention relates to the technical field of continuous casting slab cutting automatic control, in particular to a continuous casting slab cutting control system and a control method thereof. Background technique [0002] In the design and construction of the existing continuous casting plant, a suitable continuous casting machine will be selected for construction according to the configuration of the rolling mill in the subsequent process, such as whether it is a thin plate hot rolling mill or a thick plate rolling mill. At the same time, the corresponding continuous casting system also needs to configure the casting machine computer system (host computer), casting machine PLC system, cutting machine PLC system, and the corresponding control modules in it according to the conditions such as the billet command system and the destination of the billet. Automatic control of cutting. Cutting control system of Baosteel thick plate continuous casting ma...

Problems solved by technology

Its purpose is to provide a continuous casting slab cutting optimization system to overcome the shortcomings of the original system such as cumbersome operation, low work efficiency, high investment cost, and large loss of slab metal

[0006] (3) A continuous casting slab sizing method and system (Patent No. CN105665673A), which acquires the slab casting speed controlled by the frequency converter in real time; judges whether the slab at the original position or the limited position is received in place signal; when the billet in place signal is received, the billet length of the drawing and straightening machine is calculated according to the billet speed; it is judged whether the length of the billet has reached the fixed length of the billet; when the length of the billet reaches the casting length When the slab is cut to length, the cutting machine at the origin is controlled to cut the slab; the purpose is to provide a continuous casting slab sizing method and system to solve the problem of low sizing accuracy in the original technology

[0008] The characteristics of the above-mentioned methods are based on the characteristics of casting slabs produced by casting machines and the system configuration level, and the cutting of thin and thick slabs is individually optimized and controlled, and the compatibility of several command systems cannot be considered.
