摘要

In the present invention, there is disclosed a device for casting cast iron, said device including a metal chill mold (100) having outer walls (206, 208, 210) and inner walls (212, 213, 220). The inner walls are in contact with a mold (300). The device further includes pressure means (400) for applying a variable pressure on the outer walls (206, 208, 210) of the chill mold, in order to control changes in volume of molten material contained inside the chill mold, and chill mold cooling means (500) for variable cooling of the inner walls (212, 213, 220) of said chill mold. A method of using said device for casting cast iron into the above-described chill mold is disclosed, too.
