A core for blow-forming the lining of a vessel for molten metal, which core is provided with a main body having blow-in holes and an exhaust port, the side face and the lower faces of said body having the same dimensions and shapes as those of the inside of the lining of said vessel for molten metal, a flange mounted approximately horizontally in the outer direction at the periphery of the upper end of said main body, a plurality of supports which are actuated downwardly from said flange, and airtight and shock absorbers mounted beneath said flange, a lining method which uses said core, and a lining composition used in said lining method.
A core for blow-forming the lining of a vessel adapted to contain molten metal, which core is provided with a main body having blow-in holes and an exhaust port, the side face and the lower faces of said body having essentially the same dimensions and shape as the inside lining of said vessel for molten metal, a flange mounted approximately horizontally in the outer direction at the periphery of the upper end of said main body, a plurality of supports which are actuated downwardly from said flange, and shock absorber means mounted beneath said flange adapted to engage said vessel for molten metal to form an essentially airtight seal between said flange and said vessel for molten metal.
A method for lining a vessel for molten metal, which comprises the steps of inserting and arranging, from the opening portion of the vessel, a core for the blow-formation which is provided with a main body having blow-in holes and an exhaust port, the side face and the lower faces of said body having essentially the same dimensions and shapes as those of the inside of the lining of said vessel for molten metal, a flange mounted approximately horizontally in the outer direction at the periphery of the upper end of said main body, a plurality of supports which are actuated downwardly from said flange, and shock absorbers mounted beneath said flange adapted to engage said vessel for molten metal to form an essentially airtight seal between said flange and said vessel for molten metal, and blowing a mixture consisting of an aggregate, a self-hardening resin and a hardener into a space formed between the outer periphery of said core and the inner surface of said vessel thereby to fill the space.
