Method for producing temperature rising slag for rising temperature of metal in ladle

摘要

The present invention relates to a method for the slag temperature increase for the temperature increase of the molten steel inside the ladle, in more detail relates to a method for the slag temperature was raised for saving energy and temperature increase of the molten steel inside the ladle that can shorten the heat-up time to improve the temperature rise efficiency of the slag when tapping into an electrical inlet,. ; The present invention provides a method for the slag temperature increase for the temperature increase of the molten steel inside the ladle is made before the arrival to the electric arc heating device, the temperature is raised to and then to the slag and the molten steel in the ladle is tapped from the electric furnace is stronger, the casting completed by taking the liquid slag to have a weight corresponding to 64% to 250% of the weight of the slag is tapped into the ladle from the furnace from the high temperature of the molten steel remaining in the ladle is introduced into the ladle from the furnace top of the solidified slag By such administration, and the administration of the electric furnace from gyeongso equal to 15% by weight of dolomite and 50% of the slag weight injected into the ladle to the upper part of the solidified slag to form a slag with a temperature increase for the high temperature in the liquid layer to improve the temperature rise efficiency of the slag and the molten steel in the ladle and to improve heat-up time and rate, of 0.5% of the molten steel is tapped into the ladle from the molten steel in the electric furnace of high temperature remaining in the finished casting-ladle weight equal to 15% taking the molten steel to have been put into the improvement in the electric furnace slag in the ladle and the ladle steel silsuyul by administering to the top of the solidified slag and the molten steel temperature increase of efficiency, and recycling the liquid steel slag to be discarded in port after casting can be reduced by the loss of Cheorwon.
