METHOD FOR CONTROLLING TEMPERATURE OF CASTING |
摘要 |
PURPOSE: A casting temperature control method is provided to predict the temperature of the molten steel in the last stage of a casting process, thereby preventing quality failure or a stop of the casting process. CONSTITUTION: A casting temperature control method includes the following steps of: measuring the temperature of molten steel inside a tundish; calculating a temperature gradient based on an initial measurement value among the measured temperatures of the molten steel; determining whether the calculated temperature gradient is smaller than a reference temperature gradient or not; and increasing a casting speed for maintaining the temperature of the molten steel in the last stage of a casting within a molten steel managing range of the tundish. [Reference numerals] (AA) Start; (BB) End; (S10) Measure the temperature of molten steel in a tundish; (S20) Calculate the slope of the temperature by using an initially measured value among the measured temperatures of the molten steel; (S30) Slope of the temperature < a reference temperature?; (S40) Increase the casting speed; (S41) Maintain the casting speed |
