Abstract

1,216,103. Continuous casting. UNITED STATES STEEL CORP. 29 Jan., 1968 [14 Feb., 1967], No. 4647/68. Heading B3F. A chill plate 23 is placed on the top 19 of a starter bar head 13 in a mould and pins 18 for interlocking with the casting are inserted in holes (32, with locking tangs) in the plate and through the top 19 so that their necks 22 pass into keyhole slots 17 in a slide 15 by which the pins and plate are releasably secured when the slide is moved to the right, from the position shown, by the weight of a plunger rod 24 extending through a longitudinal opening 12 through the starter bar and pivotally linked to a slide lug 29. The free end of the plunger rod 24 extends out of the bottom of the starter bar (with the slide 15 moved to the right) to contact a basket (41), when the bar and strand descend, to cause the rod to rise in the bar and move the slide 15 to the release position shown and allow the basket to lower the bar, minus the pins 18 and chill plate 23, for storage horizontally. A curved guide roll rack (42) is moved to deflect the strand. The slide 15 in the starter bar head 13 is retained in the release position shown, when assembling the chill plate 23 and pins 18, by an abutment 36 on it engaging a sprung latch 30 which is released, however, by the insertion of the last pin 18a to secure the plate and pins. To avoid splashing of the pin heads, there is at least one apertured cylindrical splash shield 31 on the chill plate 23 to receive poured steel. The body 11 of the starter bar is formed of interlocked longitudinal sections.
