What is the ladle made out of that is used in molten steel processing?

The ladle used in molten steel processing is typically made of refractory materials, such as alumina, silica, and magnesia, which can withstand high temperatures. Additionally, the ladle may have a steel shell for structural integrity and to provide support. Insulating layers are often included to minimize heat loss during the transfer of molten steel. Some ladles may also be lined with special materials to protect against chemical reactions with the molten metal.
