Abstract
PURPOSE: To decrease the erosion of lining refractory materials with basic molten slag such as converter slag by lining the slag line part of the acidic lining refractories of a ladle or the like with an acidic slag modifier.
CONSTITUTION: The inside surface of a vessel 1 for molten steel such as ladle, tundish or the like is lined with inexpensive pyrophyllitic refractories of high spalling resistance and small coeffts. of thermal expansion. Since the pyrophyllitic refractories are acidic refractories, the basic converter molten slag 5 flowing into the vessel during receiving of molten steel from a converter or the like erodes the pyrophyllitic refractories. In order to prevent this, an acidic slag modi fier 3 such as volcanic ashes is beforehand sprayed to the slag line 2 of the lining refractories of the vessel 1. When the basic molten slag 5 from the converter contacts with the slag line 2, part of the modifier 3 penetrates into the slag 5 and forms a slag modifying layer 6 of small basicity in ring-shape, thereby decreasing the erosion of the pyrophyllitic lining refractories.
