Abstract
An elongate rigid arcuate starting bar has a socket in a surface, and a dog that travels along a fixed arcuate track, under the influence of a fluid actuated cylinder-piston assembly, engages the starting bar socket and retracts the bar into a stowage therefor above a run-out table on which a continuous cast strand travels. The track is so shaped that the dog disengages from the starting bar, and also engages the starting bar automatically.
Claims10
A continuous metal casting machine of the type including a mold from which a cast strand is withdrawn through powered pinch rolls and a strand straightener and disconnect apparatus, wherein the improvement comprises:
- a. an arcuate starting bar adapted for sealing said mold and for connection to said cast strand;
- b. means supporting said starting bar in a position adjacent said machine from which position said bar can move into operative association with said machine;
- c. guide means disposed parallely to said arcuate starting bar in said position;
- and
- d. bar actuating means cooperating with said guide means and carring means for moving said bar into and out of, and for holding said bar in, said position.
A continuous metal casting machine of the type comprising a mold from which a strand is withdrawn through powered pinch rolls and a strand straightener and disconnect apparatus, wherein the improvement comprises:
- a. an arcuate jointed rigid starting bar adapted for closing said mold and connecting to said strand, said starting bar cooperating with said pinch rolls and said straightener and disconnect apparatus as a means for withdrawing said strand from said mold;
- b. structural means supporting said starting bar in a position adjacent said machine from which position said bar is movable into operative association with said machine;
- c. an arcuate track mounted to said structural means and disposed parallely to said bar, said track having an end portion disposed angularly divergent away from said bar;
- d. a dog movably mounted to said track having a dependent portion engageable with said bar for engaging said bar;
- e. fluid actuated means mounted to said structural means and to said dog for moving said dog along said track including said angularly divergent portion thereof;
- and
- f. means for actuating said fluid actuated means whereby the dependent portion of said dog engages said bar and moves it when said dog travels along said arcuate track, and releases said bar when said dog travels along said angularly divergent portion of said track.
A continuous metal casting machine of the type comprising a mold from which a cast strand is withdrawn through powered pinch rolls and a strand straightener and disconnect apparatus, wherein the improvement comprises:
- a. an arcuate starting bar comprising arcuate segments joined rigidly together by tongue and clevis with pin connection therethrough;
- and
- b. an arcuate end piece connected to one end of said bar so as to be pivotable only in the direction toward the center of curvature of said arcuate bar, and adapted for sealing mold and coacting with said cast strand.
A continuous metal casting machine of the type comprising a mold from which a cast strand is withdrawn through powered pinch rolls and a strand straightener and disconnect apparatus, wherein the improvement comprises:
- a. an arcuate starting bar comprising arcuate segments releasably joined together and a pivotable head end portion adapted to close the bottom of said mold, said heating bar being inflexible;
- and
- b. a socket in a concave surface of said bar adapted to cooperate with means for moving said bar into and out of a position relative to said machine and for holding said bar in said position.
In a continuous metal casting machine of the type including a mold from which a cast strand is withdrawn through powered pinch rolls and a strand straightener and disconnect apparatus, a starting bar for withdrawing said cast strand from said mold comprising:
- a. a plurality of arcuate segments secured together and forming said bar, whereby said bar is inflexible;
- b. a head end portion secured to one end of said bar that is pivotable only in the direction toward the center of curvature of said arcuate starting bar, said head end portion being adapted for cooperation with and sealing said mold and for attachment to said cast strand;
- c. a recess in a concave surface of said bar;
- and
- d. means cooperative with said recess for moving said bar along an arcuate path and for holding said bar in a stowed position relative to said machine.
