FURNACE CONTROL FOR MANUFACTURING STEEL USING SLAG HEIGHT MEASUREMENT AND OFF-GAS ANALYSIS SYSTEMS

摘要

Embodiments of the invention comprise measuring the slag height level using a slag height level measurement system, as well as analyzing the off-gas components in a furnace using an off-gas analysis system in order to more efficiently control the furnace during a steelmaking process. The slag height level measurement system and the off-gas analysis system may be utilized to determine when the scrap steel has melted, when the slag height level has decreased, and if the slag height level has decreased due to deficient carbon and/or oxygen, or excess carbon and/or oxygen in the furnace.
