Abstract
PURPOSE:To prevent bend at lower end of a sub-lance by rotating the sub-lance arranged at an out-of-center position in a furnace, submerging a probe for measuring fitted to the lower end thereof and measuring molten metal temp. and carbon concn. CONSTITUTION:The sub-lance 20 fitting the probe 22 for measuring at the end part is descended to the position, which is out of the center in the furnace 10 during blowing. Next, the probe 22 is submerged into the molten metal 12, and also the sub-lance 20 is rotated while making center line of the axis thereof. Then, the heat quantity to the sub-lance 20 is made to symmetrically receive to the axis thereof and the expanded length is made to uniform. By this method, the bending at the lower end of the sub-lance 20 is prevented and the probe 22 for measuring at the next time is rapidly and surely fitted to the lower end of the sub-lance 20 and the hitting ratio at finishing temp. is improved.
