Abstract
Abstract Apparatus is disclosed for inductively heating a large metal ingot having a length dimension which is greater than the greatest cross-sectional dimension thereof. The apparatus includes support means for an ingot to be heated, and induction heating coil means which surrounds an ingot on the support means. The coil means is pivotally supported relative to the support means for movement between first and second positions relative to the support means. In one of the coil positions the support means is exposed for the removal or placement of an ingot thereon, and in the other of the coil positions the support means and ingot are surrounded by the coil means. Wall means may be provided at opposite ends of the coil means to define therewith and with the support means an enclosure for heating an ingot.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
100 words
Apparatus for the induction heating of a metal ingot comprising, support means for an ingot to be heated, a heating coil having an axis and including continuous conductor means extending about said axis, means supporting said heating coil for pivotal movement between first and second positions relative to said support means and about an axis transverse to said coil axis, said coil when in one of said positions exposing said support means and when in the other of said positions being disposed to inductively heat an ingot on said support means, and means to supply said coil with alternating current.
Claim 2
Dependent Claim
100 words
Apparatus for the induction heating of a metal ingot comprising, support means for an ingot to be heated, a heating coil having an axis and including continuous conductor means extending about said axis, means supporting said heating coil for pivotal movement between first and second positions relative to said support means and about an axis transverse to said coil axis, said coil when in one of said positions exposing said support means and when in the other of said positions being disposed to inductively heat an ingot on said support means, and means to supply said coil with alternating current.
Claim 3
Dependent Claim
17 words
Apparatus according to claim 1, and means to pivot said coil between said first and second positions.
Claim 4
Dependent Claim
47 words
Apparatus according to claim 1, and wall means at opposite ends of said coil, said wall means, ingot support means and coil defining an enclosure, and at least one of said wall means being movable relative to said support means to permit pivotal movement of said coil.
Claim 5
Dependent Claim
34 words
Apparatus in accordance with claim 3, wherein said one wall is a door pivotally supported for movement relative to said support means and independent of said coil means, and means to move said door.
Claim 6
Dependent Claim
29 words
Apparatus according to claim 1, wherein said coil is comprised of two coil sections each supported for pivotal movement between first and second positions relative to said support means.
Claim 7
Dependent Claim
21 words
Apparatus according to claim 5, and means to move each of said coil sections between said first and second positions thereof.
Claim 8
Dependent Claim
35 words
Apparatus according to claim 5, and wall means at opposite ends of said coil sections, both of said wall means being movable relative to said support means to permit pivotal movement of said coil sections.
Claim 9
Dependent Claim
58 words
Apparatus according to claim 7, wherein said wall means are doors disposed transversely of the axis of said coil adjacent the outer most ends of said coil sections, each of said doors being pivotally supported for movement relative to said support means and independent of the corresponding one of said coil sections, and means to move said doors.
Claim 10
Dependent Claim
23 words
Apparatus according to claim 5, wherein said support means includes means movable relative to said coil sections and transverse to said coil axis.
Claim 11
Dependent Claim
24 words
Apparatus according to claim 9, wherein said support means includes track means, and said movable means includes wheeled carrier means on said track means.
Claim 12
Dependent Claim
15 words
Apparatus according to claim 9, and wall means at opposite ends of said coil sections.
Claim 13
Dependent Claim
63 words
Apparatus according to claim 1, and a second coil having an axis and including continuous conductor means extending about the axis thereof, means supporting said second coil for pivotal movement between first and second positions relative to said support means and about an axis transverse to the axis of said second coil, and means to separately supply alternating current to said second coil.
Claim 14
Dependent Claim
26 words
The apparatus according to claim 12, wherein said support means includes means movable relative to said coil and second coil and transverse to the axes thereof.
Claim 15
Dependent Claim
24 words
Apparatus according to claim 13, wherein said support means includes track means, and said movable means includes wheeled carrier means on said track means.
