Abstract

Abstract Continuously casting molten metal into a mould through an opening of a tundish, the mould is directly connected to the tundish through a refractory coupling piece secured to the tundish around the opening, reinforcing members are secured to the side surfaces of the tundish to reinforce the connection between the same and the mould and an oscillating mechanism is connected to the reinforcing members to oscillate in the vertical direction the tundish together with the mould.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 154 words
In a nozzle-less apparatus for casting molten metal into a mould (7) through an opening (5) of a tundish (1), the improvement which comprises: a refractory coupling piece (6) secured to said tundish around said opening (5), the lower surface of said coupling piece being directly connected to said mould (7); reinforcing means (9) secured to the side surfaces of said tundish (1) and extending around a substantial portion of the interconnection of said mould (7) to said tundish (1) via said refractory coupling piece (6) to reinforce the connection between said tundish (1) and said mould (7); cooling means (8) interposed between the side surfaces of said mould (7), and said reinforcing means (9), whereby said tundish, said coupling piece, said reinforcing means, said cooling means and said mould form a unitary assembly; and an oscillating mechanism (10) connected to said reinforcing means (9) to oscillate said unitary assembly in the vertical direction.
Claim 2
Dependent Claim 154 words
In a nozzle-less apparatus for casting molten metal into a mould (7) through an opening (5) of a tundish (1), the improvement which comprises: a refractory coupling piece (6) secured to said tundish around said opening (5), the lower surface of said coupling piece being directly connected to said mould (7); reinforcing means (9) secured to the side surfaces of said tundish (1) and extending around a substantial portion of the interconnection of said mould (7) to said tundish (1) via said refractory coupling piece (6) to reinforce the connection between said tundish (1) and said mould (7); cooling means (8) interposed between the side surfaces of said mould (7), and said reinforcing means (9), whereby said tundish, said coupling piece, said reinforcing means, said cooling means and said mould form a unitary assembly; and an oscillating mechanism (10) connected to said reinforcing means (9) to oscillate said unitary assembly in the vertical direction.
Claim 3
Dependent Claim 25 words
Apparatus according to claim 1 wherein said cooling means completely surrounds and contacts the portion of said mould adjacent said tundish and refractory coupling piece.
Claim 4
Dependent Claim 26 words
Apparatus according to claim 2 wherein said cooling meanS further contacts at least a portion of said refractory coupling means to cool said refractory coupling means.
Claim 5
Dependent Claim 20 words
Apparatus according to claim 2 wherein said cooling means contacts the inner surfaces of said reinforcing means to cool same.
Claim 6
Dependent Claim 39 words
Apparatus according to claim 1 wherein said mould has a notch formed in the upper surface thereof for receiving a protrusion of said refractory coupling piece, so that said refractory coupling piece firmly couples to, and contacts, said mould.
Claim 7
Dependent Claim 35 words
Apparatus according to claim 1 wherein said tundish has a notch formed therein to receive a protrusion of said refractory coupling piece, so that said refractory coupling piece firmly couples to, and contacts, said tundish.
Claim 8
Dependent Claim 15 words
Apparatus according to claim 1 wherein said reinforcing means (9) extends completely around said interconnection.
