Abstract

A method and system for approximately indicating the temperature of molten steel is described. A temperature sensor is immersed in the molten steel and produces an output signal which indicates the temperature sensed by the sensor. The temperature output signal is sampled and a number of sample temperature values are produced. These values are stored by the system for evaluation. A plurality of stored sample values are intercompared, and if they fall within a given range, or band, of values, the existence of a temperature dwell is indicated. The system then calculates an approximate dwell temperature using the intercompared values. An alternative disclosed system additionally includes an oxygen sensor, related components and a switching network permitting the system to successively operate to approximate oxygen and temperature levels in molten steel.
