Ladle difference between tank type VOD furnace and barrel type VOD furnace
There is a difference between the ladle of the tank type VOD furnace and the barrel type VOD furnace: the ladle of the former is not equipped with a sealing flange, and its free space fluctuates between 610～1400mm due to the different capacity of the ladle; while the latter is equipped with a flange to maintain the seal.

And the free space is 25%-50% higher than the former, that is, there must be a free space of 1500-2000mm to withstand intense stirring and boiling. The lining of the VOD furnace withstands higher temperatures and the molten steel is agitated fiercely. The chemical erosion and mechanical erosion it undergoes is more serious than other refining methods outside the furnace. Therefore, the selection of refractory materials for the lining should be particularly strict, and magnesium chrome brick type magnesia dolomite bricks generally have a lining life of 25-30 furnaces, up to 100 furnaces. In order to accelerate decarburization, breathable bricks are installed in the center of the bottom of the ladle so that the upwelling argon bubbles push the slag on the molten steel surface to the ladle wall, exposing the fresh molten steel to the oxygen jet.
