A continuous casting furnace (10) of modular design. The furnace is made of a crucible section (16) a feed section (18) and a die section (12). Each of these various sections are separable from the other parts, and each of these parts is in turn made up of various individual components. Thus, the crucible section includes a refractory liner (24) made of a non carbon containing material which may be disposed within a monolithic graphite crucible (22). The graphite crucible is provided with a cylindrical aperture at its bottom which receives a feed tube (30), there being a soft seal (32) between the bottom of the liner (24) and the top of the feed tube (30). The feed section and the die section are generally formed in the same manner in that there is a non carbon containing refractory tubular member (48, 64) disposed within a graphite member (50, 62). Between the feed section (18) and the die section (12) is a soft seal (66). The soft seals ( 34, 66) are formed of a soft felt or the like fabricated from aluminum oxide, zirconium oxide or other suitable fibers which may be impregnated with a boron nitride slurry. The various parts are held together using conventional fastening means.
A continuous casting furnace for use with metals capable of dissolving carbon, the furnace being of a modular construction utilizing a graphite metal containment system lined with suitable non carbon containing refractory materials;
A continuous casting furnace of modular design comprising:
The continuous casting furnace as set forth in 18 wherein the flexible seal is comprised of a non carbon containing refractory material or a mixture of said material fabricated into a paper, cloth or felt-like consistency.
The continuous casting furnace as set forth in 19 wherein the flexible sealing means is comprised of one or more non carbon containing refractory materials selected from the group consisting of aluminum oxide and zirconium oxide fabricated into a paper, cloth or felt-like consistency.
A continuous casting furnace for use with metals capable of dissolving carbon, the furnace being of a modular construction and including:
A continuous casting furnace for use with metals capable of dissolving carbon, the furnace being of a modular construction utilizing a graphite metal containment system lined with suitable non-carbon containing refractory materials;
