ABSTRACT:
Refractory erosion detection devices are positioned in the refractory lining of metallurgical vessels, such as ladles and refractory stirring plugs incorporated in such vessels through which stirring gas is directed, comprise metal rods positioned in the upper or outer portions of the refractory bodies with their inner ends spaced from the opposite surfaces of the refractory body so that molten metal introduced into the metallurgical vessels erodes the refractory bodies and the metal rod to a point where the complete erosion and absence of the metal rods visually indicates the pre-determined thickness of the remaining refractory bodies indicating the need of replacement of the same.
