Method and apparatus for controlling the temperature of steel from the surface of the bath of a continuous casting ingot mold up to the blast furnace tap

摘要

The invention relates to a method, which is used in the area of secondary metallurgy (4) in its entirety with a final temperature-determining process step (4.1) such as a ladle furnace, for controlling the temperature of steel from the surface of the bath of a continuous casting ingot mold (1) up to the furnace tap (5) of a steel producing process. According to the invention, the temperature of the steel in the surface of the bath is controlled based on the equation TML = TLI + X DEG C (X = 5 - 15 DEG C) and while respecting the same such that a jump in temperature (9) between the surface of the bath in the ingot mold (1) and a distributor (3) is detected according to the pouring rate (6) for a predetermined billet size. In addition, the ladle history (7) with regard to the time intervals, such as ladle full , ladle empty and ladle state, such as ladle bricking up and ladle age is detected as well as a jump in the temperature of steel between the distributor (3) and the last ladle furnace temperature (LF-ex).
