Method for controlling basic oxygen steelmaking
Abstract
Abstract APPARATUS CAPABLE OF BEING IMMERSED INTO A MOLTEN STEEL BATH TO OBTAIN THE TEMPERATURE OF THE BATH AND THE CARBON CONTENT OF A SAMPLE THEREOF. THE APPARATUS IS A HOLLOW RECEPTACLE HAVING A CAVITY CAPABLE OF CAPABLE OF RETAINING AND COOLING A STEEL SAMPLE. THE CAVITY CONTAINS A THERMOCOUPLE WHICH RECORDS THE COOLING CHARACTERISTICS OF THE STEEL SAMPLE AND ESPECIALLY THE LIQUIDUS ARREST TEMPERATURE CORRESPONDING TO A PHASE TRANSFORMATION OF THE SAMPLE. THE LIQUIDUS ARREST TEMPERATURE IS USED AS A MEASURE OF THE CARBON CONTENT OF THE STEEL BATH. A SECOND THERMOCOUPLE MAY BE USED TO RECORD THE BATH TEMPERATURE DIRECTLY. ALSO DESCRIBED ARE PROCESSES FOR CONTROLLING VARIOUS STEELMAKING AND REFINING PROCESSES, ESPECIALLY THE BASIC OXYGEN STEELMAKING PROCESS.
