Abstract
Abstract A cast metal strand is withdrawn from a mold and through cooling means and a roller apron by a withdrawal mechansim having hydraulically activated drive rollers connected with their hydraulic fluid inputs in parallel. The drive rollers are synchronized by the strand itself, reducing pinch pressure to a minimum. The strand is then cut into billets by an automatic cutting mechanism motivated and synchronized by the moving strand.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
203 words
Apparatus for cutting billets from a strand produced by a continuous metal casting apparatus, comprising: a cutting table for receiving and passing a continuous metal strand; carrier means mounted above the table and freely movable from a position of rest forwardly in a direction parallel to the path of the strand over the table, said carrier means being also freely rotatable in a plane transverse to the direction of said path; a cutting torch adjustably mounted on the carrier means and being directed towards said path; a stop adjustably mounted on the carrier means forwardly of said torch and movable across said path; interacting cam means fixed to the table and to the carrier means, said cam means being adapted to rotate the carrier means whereby (1) the carrier means is moved forwardly from its position of rest by engagement of the stop with the free end of the strand (2) the cutting torch is moved across the strand to cut a billet of predetermined length therefrom, and (3) the stop is disengaged from the strand when the billet has been cut; and means to return the carrier means to its original position of rest when the stop is disengaged from the strand.

Apparatus for cutting billets from a strand produced by a continuous metal casting apparatus, comprising: a cutting table for receiving and passing a continuous metal strand; carrier means mounted above the table and freely movable from a position of rest forwardly in a direction parallel to the path of the strand over the table, said carrier means being also freely rotatable in a plane transverse to the direction of said path; a cutting torch adjustably mounted on the carrier means and being directed towards said path; a stop adjustably mounted on the carrier means forwardly of said torch and movable across said path; interacting cam means fixed to the table and to the carrier means, said cam means being adapted to rotate the carrier means whereby (1) the carrier means is moved forwardly from its position of rest by engagement of the stop with the free end of the strand (2) the cutting torch is moved across the strand to cut a billet of predetermined length therefrom, and (3) the stop is disengaged from the strand when the billet has been cut; and means to return the carrier means to its original position of rest when the stop is disengaged from the strand.
Claim 3
Dependent Claim
39 words
Apparatus as claimed in claim 1 in which the carrier means comprises an axially movable rod of uniform circular cross-section, the torch and the stop each being movable axially and circumferentially on the rod and being releasably clamped thereon.
Claim 4
Dependent Claim
31 words
Apparatus as claimed in claim 1 in which the carrier return means comprises a free weight suspended from said rod and acting against the force of the strand on the stop.
Claim 5
Dependent Claim
20 words
Apparatus as claimed in claim 1 including means operable to actuate the torch during forward movement of the carrier means.
