Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
201 words
A continuous casting apparatus for producing continuous metal ingots or rods, comprising a supporting frame, a casting wheel assembly arranged for rotation on said frame and transmissively connected to relative power means and including a casting wheel,a continuous tape wound on the said casting wheel and around idle rollers, said casting wheel having a peripheral mold-like groove closed along an arc thereof by said continuous tape, and cooling devices for cooling the casting wheel assembly, the said apparatus further comprising a support unit co-axially mounted for rotation about said casting wheel and capable of being secured to said supporting frame at a number of angular positions, two idle rollers for the said tape carried by the said support unit at the periphery of said casting wheel, a taking-off or extraction means for withdrawing the produced ingot mounted on the said support unit, an idle pulley for the said tape which may be set in a plurality of positions relative to the said angular positions of the said support unit and is mounted on a support member rigid with said supporting frame, and a crucible which can be mounted in a number of positions at the periphery of the said casting wheel.
Claim 2
Dependent Claim
201 words
A continuous casting apparatus for producing continuous metal ingots or rods, comprising a supporting frame, a casting wheel assembly arranged for rotation on said frame and transmissively connected to relative power means and including a casting wheel,a continuous tape wound on the said casting wheel and around idle rollers, said casting wheel having a peripheral mold-like groove closed along an arc thereof by said continuous tape, and cooling devices for cooling the casting wheel assembly, the said apparatus further comprising a support unit co-axially mounted for rotation about said casting wheel and capable of being secured to said supporting frame at a number of angular positions, two idle rollers for the said tape carried by the said support unit at the periphery of said casting wheel, a taking-off or extraction means for withdrawing the produced ingot mounted on the said support unit, an idle pulley for the said tape which may be set in a plurality of positions relative to the said angular positions of the said support unit and is mounted on a support member rigid with said supporting frame, and a crucible which can be mounted in a number of positions at the periphery of the said casting wheel.
Claim 3
Dependent Claim
32 words
An apparatus as claimed in claim 1, wherein said cooling devices include outer cooling devices for cooling said casting wheel assembly and mounted on the said support unit and rotating therewith .
Claim 4
Dependent Claim
39 words
An apparatus as claimed in claim 1, wherein the said idle rollers are mounted on the said support unit with the interpositioning of a relative actuation device to move said rollers towards and away from the said casting wheel.
Claim 5
Dependent Claim
97 words
An apparatus as claimed in claim 3, wherein the actuation device for moving one of said idle rollers towards and away from said casting wheel comprises a slide member sliding along guides arranged on said support unit, control means such as a fluid-operated motor for actuating said slide member, actuation means connected to the said slide member and provided with a pin alternatingly moving to and fro in a radial direction with respect to said casting wheel and an arm pivoted on the said slide member and articulated to said pin and carrying the relative idle roller.
Claim 6
Dependent Claim
26 words
An apparatus as claimed in claim 1, wherein the said taking-off unit comprises power means for moving the said taking-off unit relative to said casting wheel.
Claim 7
Dependent Claim
57 words
An apparatus as claimed in claim 1, wherein the said cooling devices include outer cooling devices movably mounted relative to the said wheel and arranged in two cooling assemblies movable to and fro in a radial direction on the said support unit, the said cooling assemblies being connected to relative control means preferably of a fluid-operated type.
Claim 8
Dependent Claim
41 words
An apparatus as claimed in claim 6, wherein the support unit comprises a substantially drum-shaped structure centrally provided with a flanged sleeve mounted for rotation on a fixed sleeve and securable to the latter by means of scRews and the like.
Claim 9
Dependent Claim
63 words
An apparatus as claimed in claim 1, including a supporting member arranged on said supporting frame for sliding movement in a substantially horizontal direction, said crucible being mounted for sliding movement in a substantially vertical direction along said support power means being provided for displacing the said supporting member and said crucible to position the said crucible relative to the said casting wheel.
Claim 10
Dependent Claim
52 words
An apparatus as claimed in claim 8, wherein the said supporting member is mounted for sliding movement along two horizontal directions at right angles to one another parallel and normal, respectively, to the axis of the said casting wheel, power control means being provided to move the said support in said directions.
Claim 11
Dependent Claim
32 words
An apparatus as claimed in claim 1, wherein the said pulley is supported by a structure movably mounted on an overhanging beam which in turn is movably mounted on a fixed upright.
Claim 12
Dependent Claim
41 words
An apparatus as claimed in claim 1, wherein said cooling devices include inner cooling devices connected to securing means capable of allowing in the unsecured condition thereof the said inner cooling devices to rotate about the axis of said casting wheel.
