Abstract
Abstract In the continuous casting of metals, secured on the pulling members of endless chains which serve to withdraw an ingot from a mould are shaped insert pieces which are in direct contact with the ingot. These shaped pieces make it possible to withdraw the ingot without distorting its profile.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
231 words
A device for withdrawing ingots from a mould during continuous casting of metals comprising: a pulling stand with upper and lower driving rollers; two revolving drums rotatably secured to said pulling stand relative to its longitudinal horizontal axis and mounted so that said ingot passes therebetween during operation of said device; a pair of movable endless chains, one of which is disposed around one of said drums, the other of which is disposed around the other of said drums, said endless chains having interconnected links interacting with said upper and lower rollers of said pulling stand so that said chains are driven thereby; profiled insert means secured to each of the links of said pair of endless chains, said insert means having profiles corresponding in shape to the exterior shape of the ingot being cast; means causing at least one of said rollers to urge each link of one of said endless chains against one side of said ingot and at least another one of said rollers to urge each link of the other of said endless chains against the other side of said ingot, so that successive opposing ones of said insert means on each of said chains respectively, conformably embrace said ingot as said chains move around said drums under the action of said driving rollers, whereby said ingot is withdrawn from the mold without distortion of its profile.
Claim 2
Independent Claim

A device for withdrawing ingots from a mould during continuous casting of metals comprising: a pulling stand with upper and lower driving rollers; two revolving drums rotatably secured to said pulling stand relative to its longitudinal horizontal axis and mounted so that said ingot passes therebetween during operation of said device; a pair of movable endless chains, one of which is disposed around one of said drums, the other of which is disposed around the other of said drums, said endless chains having interconnected links interacting with said upper and lower rollers of said pulling stand so that said chains are driven thereby; profiled insert means secured to each of the links of said pair of endless chains, said insert means having profiles corresponding in shape to the exterior shape of the ingot being cast; means causing at least one of said rollers to urge each link of one of said endless chains against one side of said ingot and at least another one of said rollers to urge each link of the other of said endless chains against the other side of said ingot, so that successive opposing ones of said insert means on each of said chains respectively, conformably embrace said ingot as said chains move around said drums under the action of said driving rollers, whereby said ingot is withdrawn from the mold without distortion of its profile.
Claim 3
Dependent Claim
35 words
A device, as claimed in claim 1, wherein two opposing ones of said insert means embrance between 80 to 90 percent of the surface of said ingot when said ingot passes between said driving rollers.
Claim 4
Dependent Claim
26 words
A device, as claimed in claim 1, wherein the profile of the surfaces of two opposite insert means in contact with said ingot is a circle.
Claim 5
Dependent Claim
26 words
A device, as claimed in claim 1, wherein the profile of the surfaces of two opposite insert means in contact with said ingot is an ellipse.
Claim 6
Dependent Claim
29 words
A device, as claimed in claim 1, wherein the profile of the surfaces of two opposite insert means in contact with said ingot is the shape of an H-beam.
Claim 7
Dependent Claim
29 words
A device, as claimed in claim 1, wherein the profile of the surfaces of two opposite insert means in contact with said ingot is the shape of a box.
Claim 8
Dependent Claim
29 words
A device, as claimed in claim 1, wherein the profile of the surfaces of two opposite insert means in contact with the ingot is the shape of an angle.
