Description

Technical Field

[0001] The invention belongs to the technical field of continuous casting, in particular to a titanium alloy continuous casting device. Background Art

[0002] Titanium alloy is an alloy made of titanium and other metals. Titanium alloy has the advantages of high strength, good corrosion resistance and high heat resistance, and is widely used in various fields. Compared with the traditional die casting method, the continuous casting process can significantly improve the yield rate, save energy, simplify the production process, reduce labor intensity, reduce costs and facilitate automation. Therefore, the continuous casting process is gradually replacing the traditional process.

[0003] A patent application with publication number CN108193132A discloses a heavy steel and its production process, which includes the following steps: injecting refined molten steel into a ladle, moving the ladle containing molten steel to the top of a pouring station by a turntable, and then injecting the molten steel into a tundish, which injects the molten steel into a crystallizer, where the molten steel is cooled into a billet and fixedly connected to the upper end of a dummy rod; starting a straightening machine after pouring, and pulling the billet with the dummy rod; removing the dummy rod after the billet enters the straightening machine; measuring the length of the billet with a speed measuring roller, When the length of the billet meets the requirements, the cutting gun is used to move synchronously with the billet and start cutting. After cutting, the cutting machine is reset; the quality of the molten steel in the ladle is detected according to the gravity sensor on the turntable. When the molten steel in the ladle is poured, the turntable is rotated to move the empty ladle away from the pouring station, and another ladle filled with molten steel is moved to the pouring station, and then the molten steel continues to be poured into the tundish; when the drain port of the tundish is closed, cold steel is added to the crystallizer, the speed of pulling the billet is reduced, and the cooling intensity of the second cooling section is reduced. When the tail billet is solidified, it is pulled out.

[0004] During continuous casting production, alloy residues will exist in the tundish, which will cause the long water inlet of the tundish to be blocked. Therefore, after the pouring is completed, the tundish needs to be lifted and lowered for cleaning. During the cleaning process, the entire continuous casting production will be stopped, and the cleaning of the tundish needs to wait until the temperature of the tundish drops, which will seriously affect the production efficiency.
