Abstract
The paper describes the components of an Integrated Furnace Control system for covered-arc (shielded arc) smelting with results the recently started 75 MW Cerro Matoso Line 2 Furnace. The paper starts with a review of the mechanisms of power andfeed input and heat losses in the shielded-are smelting process, and describes how the details of the control system are tailored to the process. Thecontrol modules' of a coveredarc smelting,furnace are described including measured results and screen captures. This paper focuses on Integrated Furnace Controls tailored to shielded-arc smelting, but similar approaches have been recently applied to other furnace processes including immersed-arc smelting.
