Automatic steel feeding system and method for slab heating furnaces

Abstract

The invention discloses an automatic steel feeding system for slab heating furnaces, and relates to the technical field of automation control. The automatic steel feeding system comprises the heatingfurnaces, a plurality of steel feeding roller beds and a feeding roller bed, and further includes a slab information database, a slab predetermined position module, a human-computer interaction module, a communication module and a PLC control module. The feeding roller bed and the multiple steel feeding roller beds are connected in sequence, and the steel feeding roller beds are located at different positions of the heating furnaces. A photoelectric detecting sensor is arranged at the front end of each of the steel feeding roller beds. The slab information database and the slab predetermined position module are both connected to the PLC control module through the communication module, and the human-computer interaction module is connected with the slab information database and the slab predetermined position module. The steel feeding roller beds, the feeding roller bed and the photoelectric detecting sensor are all connected with the PLC control module. The invention further disclosesan automatic steel feeding method for the slab heating furnaces. The automatic steel feeding system and method improve the efficiency of steel feeding of slabs, reduce the energy consumption and reduce the labor intensity of operators.

Description

technical field [0001] The invention relates to the technical field of automation control, in particular to an automatic steel loading system and an automatic steel loading method for a slab heating furnace. Background technique [0002] Nangang Medium and Heavy Plate Coil Plant was completed and put into operation in 2005. Its steelmaking, continuous casting, heating furnace, rolling mill, rear finishing, etc. constitute a continuous production line, and the rolling steel (steel coil) production line is designed with a maximum rolling speed of 11m / s , with an annual production capacity of 1.5 million tons. The original steel loading method is manual steel loading, which requires operators to manually input the size data of the slab, manually open the steel roller table, and manually position the manual furnace loading, which not only seriously affects the efficiency of steel loading, but also has high labor intensity for the operators. Steel is less accurate. Contents of...
