Abstract
The present invention provides an improved lining structure composition on the inner surface of a tundish by forming an alumina-silica-base intermediate lining layer over which a magnesian surface coating layer is formed by gunning. It solves the adhesion defect on a refractory lining of the tundish and enables longer operation of the tundish.
