Abstract
A method has been developed and tested for increasing the durability of the lining of 420-ton mixer type transfer ladles for cast iron by the impregnation of the active layer with tar. At a tar temperature of 100°C the active layer is fully impregnated in 65 h. The result is a decrease in the porosity and increase in the coldcrushing strength of the chamotte brick. For a good-quality impregnation use must be made of a steam coil which will heat the tar evenly throughout the ladle volume to 100–120°C.
