Title: METHOD AND DEVICE FOR CHILL MOULDING
Abstract:
A device for casting cast iron including a metal chill mould (100) having outer walls (206, 208, 210) and inner walls (212, 213, 220). The inner walls are in contact with a mould (300). The device further includes pressurising means (400) for applying a variable pressure on the outer walls (206, 208, 210) of the chill mould, in order to control changes in volume of molten material enclosed by the chill mould, and chill mould cooling means (500) for variable cooling of the inner walls (212, 213, 220) of said chill mould. A method using said device for carrying out the invention is also disclosed.
