Embodiment Construction

[0019] Taking the production of high-grade oriented silicon steel finished strip steel as an example, the raw material slab specification is 230*1100mm, and the finished strip steel specification is 2.3*1100mm; an electromagnetic induction furnace automatic control system provided by the embodiment of the present invention includes a slab raw data processing module , the second-level model calculation module, the rolling line tracking module and the first-level PLC control module, the slab raw data processing is used to receive the set number of passes of E1R1 rolling mill 4 and the set number of passes of E2R2 rolling mill 5, and receive the set rolled pieces The target width and the target thickness of the rolled piece receive the set target width and target thickness of the intermediate billet, and the second-level model calculation module is based on the number of passes of the E1R1 rolling mill 4, the number of passes of the E2R2 rolling mill 5, the target width of the roll...

Abstract

The invention discloses an automatic control system of an electromagnetic induction furnace and a method of the automatic control system, belonging to the technical field of control on silicon steel production of a hot-rolling electromagnetic induction furnace. The system comprises an original slab data processing module, a secondary model calculating module, a rolling line tracking travel module and a primary PLC (Programmable Logic Controller) control module. With the adoption of the system, the first automatic locking of the size of a rolled piece rolled by an E1R1 rolling machine is realized, and the rolled piece is put into the electromagnetic induction furnace to be heated; after being heated, the rolled piece is taken out of the electromagnetic induction furnace, the second locking of the size of an intermediate slab is carried out automatically, and the rolling in relevant channels of an E2R2 rolling machine is carried out continuously; and finally, the strict requirements of the silicon steel on a process system are met, and the quality and the performance of the finished product are ensured. The automatic control system realizes the twice locking on the target sizes of the rolled piece and the intermediate slab entering into the electromagnetic induction furnace and the automatic rolling control without any manual interference, and meets the rigorous requirements of a narrow window process on the silicon steel.

Description

technical field [0001] The invention belongs to the technical field of control for producing silicon steel by a hot-rolled electromagnetic induction furnace, and in particular relates to an automatic control system of an electromagnetic induction furnace and a method thereof. Background technique [0002] There are currently two technical routes for the production of high-grade oriented silicon steel; one is a high-temperature heating furnace, and the other is an electromagnetic induction furnace. The realization of the electromagnetic induction furnace process route is as follows: [0003] The electromagnetic induction furnace is located between the E1R1 rolling mill and the E2R2 rolling mill of the hot rolling production line; the slab needs to be rolled into the furnace after being rolled by the E1R1 rolling mill, and its size (width and thickness) must strictly meet the requirements of the electromagnetic induction furnace. It can be normally loaded into an electromagnet...
