Method, Controller And Tundish Control System For A Continuous Casting Process

摘要

A method of controlling the temperature of molten metal in a tundish during a ladle tapping cycle in a continuous casting process. The method comprises a) obtaining a measure of a temperature of molten metal in the tundish; b) comparing the measured temperature with a desired tundish melt temperature; c) determining whether the measured temperature is lower than desired; d) controlling the temperature of the molten metal in the tundish by with a heating arrangement, and an electromagnetic stirrer which stirs the molten metal in order to distribute heated molten metal in the tundish such that the temperature of the molten metal approaches the desired temperature.

1. A method of controlling the temperature of molten metal (M) in a tundish during a ladle tapping cycle in a continuous casting process, wherein the method comprises:
a) obtaining a measure of a temperature of molten metal (M) in the tundish, b) comparing the obtained measure of temperature with a desired a desired tundish melt temperature, c) determining whether the measure of temperature is lower than the desired tundish melt temperature and in case the measure of temperature is lower than the desired tundish melt temperature, d) controlling the temperature of the molten metal (M) in the tundish by means of a heating arrangement comprising a set of one or more oxy-fuel burners which heats the molten metal (M) in the tundish, and by means of an electromagnetic stirrer which stirs the molten metal (M) in order to distribute heated molten metal (M) in the tundish such that the temperature of the molten metal (M) in the tundish approaches the desired tundish melt temperature.
