still for framstellning of profiled massgods, especially svetsringar and flensar with collar, and kokill for framstellningen

摘要

The invention refers to a process and a chill mould for the production of mass goods, especially welding rings and flanges with bearing collars. The moulded goods are produced through centrifugal casting in a chill mould (10) which has an internal form which mainly corresponds to the profile of the intended goods. According to a design of the invention, the inner surface (18, 19, 20) of the chill mould is shaped for the production of several units side by side. By means of a ring-shaped bulge (20) directed radially toward the centre of the chill mould crack forming during the hardening and cooling phase can be concentrated to the area between two units.IMAGE
