Chill Casting Machine

Chill Casting Machine

 

a foundry machine that makes possible mechanization of the chill casting process. In chill casting machines the opening and closing of the chill elements, the setting and removal of cores, and the ejection of castings from the chills are mechanized.

Chill casting machines may be of the single-position or multiposition type.

Single-position chill casting machines may be of the universal type, in which the chills may be changed to produce various castings. Mechanized chills, which are used to produce only one type of casting, also belong to the single-position category. The parts of the chill are attached to plates that move along guides. The chills range in size from 250 × 320 mm to 800 × 1,000 mm. The machine drive may be pneumatic or hydraulic.

Multiposition rotary chill casting machines usually consist of a group of single-position machines mounted on a rotating table. When the table rotates, the chills are closed, the cores are set, and the melt is poured. After the castings have hardened and have been knocked out, the chills are blown out and coated with facing for the next cycle. Conveyor-type chill casting machines have a transporting device along which travel chills or trucks with single-position chill casting machines. The chills are filled with alloy and the castings are knocked out on the conveyor.

Chill casting machines are part of automated lines. For example, at the Dinamo plant in Moscow (1972), electric motor beds are cast in chills on an automated line. The automated line includes induction furnaces, a pouring machine, two rotary chill casting machines, two units for heat treatment of the castings, and transporting devices. The line has an annual capacity of 8,000 tons of castings and is serviced by six workers.
