Abstract

The invention provides a magnesium alloy continuous casting liquid level position detection device and a detection method thereof. The magnesium alloy continuous casting liquid level position detection device comprises a cylindrical detection shell, a plurality of through holes are axially formed between the inner wall and the outer wall of the detection shell and equidistantly and uniformly arranged along the circumferential direction of the detection shell, a thermocouple is mounted in each through hole to form a thermocouple group, a measuring end group of the thermocouple group extends out of the bottom ends of the through holes, contacts with liquid level to be detected and forms a spiral, a terminal group of the thermocouple group is connected with a signal acquisition unit mounted at the top end of the detection shell, the signal acquisition unit is connected with a data processing system outside the detection shell through a communication module, the device judges between which thermocouples the liquid level to be detected is positioned according to temperature jump searched by the thermocouples positioned above and below the liquid level to be detected, the relative position of the liquid level to be detected is obtained, the liquid level position of the liquid level to be detected is timely adjusted, the liquid level of magnesium alloy melt is maintained stable, safety production of a magnesium alloy is ensured, and the quality of a cast billet is improved.

Description

technical field [0001] The invention is designed based on the field of metallurgical continuous casting equipment, especially a detection method and a device invented for the detection requirements of mold liquid level control in the magnesium alloy continuous casting process. Background technique [0002] In the magnesium alloy continuous casting process, the magnesium alloy melt is first poured into the crystallizer, and after the heat dissipation of the inner wall of the mold, the alloy melt begins to solidify from the outside to the inside and gradually moves down, realizing the continuous casting function. [0003] Due to the active characteristics of magnesium, oxidation prevention is an important control link in the continuous casting process of magnesium alloys. Usually more expensive SF 6 The mixed gas protects the liquid surface of the melt, so that it forms a protective film with magnesium, covers the liquid surface, and isolates the air from the melt, while SF ...
