<p>#CMT# #/CMT# Device for casting molded parts comprises a holding furnace (7) having a riser pipe (10) immersed in the melt and equipped with a sensor (15) for detecting the level of the melt in the riser pipe. A suction pipe (6) is arranged with a suction end in the riser pipe and is immersed in the melt of the riser pipe. The pressure in the holding furnace is controlled and/or regulated using the sensor and the level of the melt in the riser pipe is kept constant at the start of the casting process depending on the filling level in the holding furnace. #CMT# : #/CMT# An independent claim is also included for: a process for casting molded parts. #CMT#USE : #/CMT# For casting molded parts. #CMT#ADVANTAGE : #/CMT# Bath meniscus for the suction pipe is kept constant. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a schematic view of the casting device. 5 : casting chamber 6 : suction pipe 7 : holding furnace 10 : riser pipe 11 : melt bath #CMT#METALLURGY : #/CMT# Preferred Features: The sensor for detecting the level is formed as a pneumatic pressure sensor or an electric, capacitive and/or inductive sensor. A region of the lower end of the riser pipe has a filter for removing impurities from the melt in the holding furnace.</p> |
