ABSTRACT:
A casting unit 6 consists of a monolithic body which is annular in shape and has an annular flange 72 outturned about the axis and monolithically outstanding on the body at the outer periphery, a set of lugs 110 angularly spaced about the axis on the lower end portion of the body and monolithically outstanding in the aperture, and a circumferential groove 114 about the outer periphery of the body in the upper end portion, with mullions 20 monolithically upstanding therein, adjacent the outer periphery of the groove, to form ports 112.The groove is interconnected with the cavity 108 in the lower end portion of the body at the aperture; and passages, 126, 140, a graphite ring 16, and whatever else is required, are added to complete the unit 6 before it is supported in an aperture in a metal casting table 2, having liquid coolant discharge means 14 circumposed thereabout and a stool to support molten metal after being mated with the lugs. Where the liquid coolant discharge means take the form of a liquid coolant box, the housing 22, 24 of which defines the table, and the casting unit is upwardly inserted in the box, at an aperture 26 in the bottom, and abutted with the top of the chamber 14, a device 17 is provided for sensing leakage between the casting unit and the top of the chamber. The leakage is discharged in a passage 140 passing through one of the mullions to the bottom of the casting unit.
