Abstract
Abstract The cast piece supporting apparatus disclosed includes cast piece supporting and cooling members, which are disposed just beneath a mould and movable in the upward and downward directions in synchronism with the upward and downward movements of said mould while encircling the outer peripheral surface of said cast piece. The apparatus also includes driving means for making the cast piece supporting and cooling members either closely contact with, or separate from, said outer peripheral surface of said cast piece, and means for equalizing the lowering speed of said mould to the drawing speed of said cast piece. Upon lowering the cast piece supporting and cooling members, these members are made to closely contact with said outer peripheral surface of said cast piece, while upon raising the same, the members are made to separate from said outer peripheral surface of said cast piece.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
281 words
In apparatus for carrying out a continuous casting process wherein molten metal is continously moulded into a cast piece which is supported and cooled, and is drawn at a selected speed from downstream of where the cast piece is moulded, supported and cooled, a cast piece supporting apparatus for a continuous casting machine for drawing the cast piece, comprising: a downwardly opening mould; means connected to said mold for cyclically vertically raising the mould faster than the selected drawing speed to an upper position and for permitting the mould to descend to a lower position as a cast piece issues downwardly therefrom whereby the mould is vertically reciprocated; said means connected to said mold including means for regulating the speed of descent of the mould to equalize the speed of descent of the mould with the selected speed of drawing of the cast piece; cast piece supporting means including plate means engageable with the periphery of the cast piece adjacent where the cast piece issues from the mould; means co-mounting the cast piece supporting means with the mould for vertically reciprocating the cast piece support means in synchronism with the vertical reciprocation of the mould; means for cooling the cast piece located adjacent where the cast piece issues from the mould; and means connected to said plate means for laterally moving the plate means into and out of engagement with the cast piece in synchronism with the vertical reciprocation of the mould according to a plan wherein the plate means are engaged with the cast piece so long as the mould is lowering and are retracted out of contact with the cast piece so long as the mould is being raised.
Claim 2
Dependent Claim

In apparatus for carrying out a continuous casting process wherein molten metal is continously moulded into a cast piece which is supported and cooled, and is drawn at a selected speed from downstream of where the cast piece is moulded, supported and cooled, a cast piece supporting apparatus for a continuous casting machine for drawing the cast piece, comprising: a downwardly opening mould; means connected to said mold for cyclically vertically raising the mould faster than the selected drawing speed to an upper position and for permitting the mould to descend to a lower position as a cast piece issues downwardly therefrom whereby the mould is vertically reciprocated; said means connected to said mold including means for regulating the speed of descent of the mould to equalize the speed of descent of the mould with the selected speed of drawing of the cast piece; cast piece supporting means including plate means engageable with the periphery of the cast piece adjacent where the cast piece issues from the mould; means co-mounting the cast piece supporting means with the mould for vertically reciprocating the cast piece support means in synchronism with the vertical reciprocation of the mould; means for cooling the cast piece located adjacent where the cast piece issues from the mould; and means connected to said plate means for laterally moving the plate means into and out of engagement with the cast piece in synchronism with the vertical reciprocation of the mould according to a plan wherein the plate means are engaged with the cast piece so long as the mould is lowering and are retracted out of contact with the cast piece so long as the mould is being raised.
Claim 3
Dependent Claim
25 words
The cast piece supporting apparatus of claim 1 wherein the cooling means are co-mounted with the cast piece supporting means for vertical, reciprocating movement therewith.
Claim 4
Dependent Claim
33 words
The cast piece supporting apparatus of claim 1 wherein the cooling means include cooling fluid spray nozzle means aimed to spray cooling fluid on the plate means of the casting piece support means.
Claim 5
Dependent Claim
28 words
The cast piece supporting apparatus of claim 1 wherein the cooling means include cooling fluid spray nozzle means aimed to spray cooling fluid directly on the cast piece.
Claim 6
Dependent Claim
62 words
The cast piece supporting apparatus of claim 1 wherein the mould is of rectangular internal transverse cross-section and the plate means are constituted by four plates positioned to engage corresponding sides of the cast piece; the cooling means including cooling fluid spray nozzle means aimed to spray cooling fluid on the four plates and between adjacent plates directly onto the cast piece.
Claim 7
Dependent Claim
39 words
The cast piece supporting apparatus of claim 1 wherein the mould is of rectangular internal transverse cross-section and the plate means are constituted by two L-shaped plates each positioned to engage two adjacent corresponding sides of the cast piece.
Claim 8
Dependent Claim
43 words
The cast piece supporting apparatus of claim 1 wherein the mould is of oblong rectangular internal transverse cross-section and the plate means are constituted by a plurality of guide bars positioned to engage the two opposite wider corresponding sides of the cast piece.
Claim 9
Dependent Claim
152 words
The cast piece supporting apparatus of claim 1 wherein the means for cyclically raising the mould and for permitting the mould to descend and the means for laterally moving the plate means comprise hydraulic piston and cylinder means arranged in a hydraulic fluid circuit having means for pressurizing the hydraulic fluid and valving for controlling the direction of movement of the piston means within the cylinder means; the valving including limit switch means for ascertaining when the mould has been raised to said upper position and when the mould has descended to said loWer position, and for switching said valving in response to such ascertainment; and wherein the regulating means includes control valve means adjustable to control the flow of the hydraulic fluid for adjusting the resistance the hydraulic fluid presents to descent of the mould whereby the rate of descent of the mould may be equalized with the selected drawing speed.
