Abstract

1,186,917. Casting processes; chills; continuous casting. TEXAS INSTRUMENTS Inc. 18 Aug., 1967 [10 Nov., 1966], No. 38229/67. Heading B3F. [Also in Division C7] In order to limit the number of pimples exposed at the etched surface of a printing plate, a billet from which the plate is rolled is cast from a Zn alloy having less than 70 p.p.m. Fe (which is presumed to cause pimple-forming concretions in the billet) and heat is removed from at least one surface of the melt at a rate between 0À001 and 3À00 Btu/1b/sec. If a water-cooled copper chill plate 5 is placed at one end of a low heat conducting mould, there are less concretions near the plate. An eight foot billet (11), Fig. 4 (not shown), 22 inches wide and 2¢ inches thick may be cast in a mould (9) with the necessary heat conductivity so that its bottom provides the required cooling. After rolling to 0À032 or 0À064 inch, it is the chilled face which is etched for printing. The plate may have a bonded backing layer (3) of aluminium. Continuous casting.-A billet 35, Fig. 6, may be cast on a starting stool 29 with key-pieces 31, through a mould having liquid cooling passages 28, 30 so that the concretions are lessened on all surfaces.
