Ladle is one of the equipment required for steelmaking process. With the improvement of converter life, the increase of continuous casting ratio and the progress of refining technology outside the furnace, the ladle is in increasingly harsh conditions of use such as large capacity, multiple steel types, high temperature and long time, and the requirements …
Configuration of refractories for converters In the dismantling of the furnace lining after use, it was found that the damage was caused by the inability to use individual parts of the severe erosion, while many other parts could be used, but had to be discarded in order to build a new lining. Therefore, people put …
