Research on the Database Construction of Furnace Material Consumption in EAF Steelmaking Process

摘要

As the three-level management system for material consumption in the EAF steelmaking plant cannot obtain statistics and carry calculation of material consumption for each furnace, the data from the system cannot provide guidance for actual smelting operation. In this paper, the field PLC process smelting data of the material consumption in "EAF-LF-CC" process were collected from Kepware as OPC Server and by VS2010 as development tool. Then, they were classified (in categories of scrap charging, auxiliary materials, gas consumption, injection information, power supply data, etc.) and stored into Microsoft SQL Server 2008 database to build a database of furnace material consumption. The database construction provides guidance for reducing the material consumption and optimizing smelting operation for each furnace.
