Abstract
Abstract Apparatus for continuous casting having a plurality of casting positions and comprising a casting wheel with a metal band associated therewith and a crucible for feeding molten metal to the casting wheel. The apparatus further comprises a roller for pressing the band at the feed portion, and an idle pulley for stretching the band. The crucible, the pressing roller and the idle pulley are mounted on a support structure hinged to the base frame of the apparatus coaxially with the casting wheel. The support structure consists of a column and it can be rotated through a certain arc by suitable drive means.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
196 words
An apparatus for continuous casting of metal, comprising a frame, a casting wheel rotatably supported by said frame, a crucible for feeding molten metal to said casting wheel, a peripheral groove in said casting wheel, a metal band covering said groove along an arc portion to define a metal receiving mold therewith, a band pressing roller arranged substantially at the point at which molten metal is fed into said groove, an idle pulley for said band arranged at a distance from said casting wheel, a support structure for said idle pulley and for said band pressing roller, and means for cooling said casting wheel and said band, wherein said support structure includes a column supporting said idle pulley at one end and hinged at the other end to said frame coaxially with said casting wheel and an arm rigid with said column for supporting said band pressing roller, and wherein said crucible is adjustably supported by said column, the apparatus further comprising means for angularly displacing said column and means for displacing said crucible with respect to said column to position said crucible in any preferred casting position along a relevant arc of said casting wheel.
Claim 2
Independent Claim
196 words
An apparatus for continuous casting of metal, comprising a frame, a casting wheel rotatably supported by said frame, a crucible for feeding molten metal to said casting wheel, a peripheral groove in said casting wheel, a metal band covering said groove along an arc portion to define a metal receiving mold therewith, a band pressing roller arranged substantially at the point at which molten metal is fed into said groove, an idle pulley for said band arranged at a distance from said casting wheel, a support structure for said idle pulley and for said band pressing roller, and means for cooling said casting wheel and said band, wherein said support structure includes a column supporting said idle pulley at one end and hinged at the other end to said frame coaxially with said casting wheel and an arm rigid with said column for supporting said band pressing roller, and wherein said crucible is adjustably supported by said column, the apparatus further comprising means for angularly displacing said column and means for displacing said crucible with respect to said column to position said crucible in any preferred casting position along a relevant arc of said casting wheel.
Claim 3
Dependent Claim
87 words
An apparatus as claimed in claim 1, wherein said band pressing roller is adjustably mounted on said arm, the means for adjusting said roller with respect to said arm including a drum rotatably arranged on the free end of said arm, an elongated support body rotatably supporting said band pressing roller at one end and hinged to said drum in an eccentric position, and means for rotating said drum, whereby rotation thereof causes said band pressing roller to be displaced peripherally with respect to said casting wheel.
Claim 4
Dependent Claim
39 words
An apparatus as claimed in claim 1, in which said crucible is mounted on a substantially semi-cylindrical cradle and comprises a nozzle hinged to said crucible at a point lying substantially on the axis of said substantially semi-cylindrical cradle.
Claim 5
Dependent Claim
17 words
An apparatus as claimed in claim 3, in which said cradle is slidably mounted on said column.
