A method for the investigation of the behavior of binder systems, during the casting of the sand cores

摘要

It is a device for the investigation of the behavior of binder systems of the sand cores in the casting of metal parts by the introduction of sample cores proposed in a molten metal, with which a with a tubular probe (15) of these sample core (13) in a sample the form of (11) completely into the molten metal bath (12) is immersed and, in the introduction of the sample gas escaping core (13) is derived and is collected for time-related quantity determination. This comprises a with the probe (15) via a connecting line (16) connected gas collection vessel (24), a fixed suspended, downwardly open, water-filled cylinder (24), in which the connecting line (16) opens, a under the cylinder (24) standing water-filled tank (22), and a the cylinder (24) or the tank (22) carrying the scale (25), wherein the downwardly open opening of the cylinder (24) to the beginning of the test below the water level of the pelvis (22) and is filled free from gas bubbles.
