METHOD FOR CONTROLLING MOLTEN STEEL TEMPERATURE IN LADLE

摘要

PROBLEM TO BE SOLVED: To provide a method for controlling molten steel temperature in a ladle by which the temperature in the molten steel poured into a tundish can suitably be controlled without relaying on the experience of an operator in a refining process.;SOLUTION: A thermocouple 6 is embedded into the bottom part of the ladle 1 for transporting the molten steel to the tundish and also, a vacuum heat-insulating vessel 8 encapsulated with a wireless transmitter 7 for sending the temperature data detected with the thermocouple 6 is fitted to the outside of the ladle 1. The temperature data sent from the wireless transmitter 7 is received with reception antennas 25 disposed at respective positions, and the molten steel temperature in the ladle is continuously or intermittently measured and the molten steel temperature in the refining process is controlled so that the molten steel temperature in the ladle becomes the suitable temperature. The control of the molten steel temperature in the refining process can be performed, for example, by controlling the quantity of oxygen to be blown into the molten steel.;COPYRIGHT: (C)2009,JPO&INPIT
