Embodiment 1

[0031] This embodiment is a water-cooled crystallizer used when casting a hollow titanium ingot in a cold bed electron beam furnace, which includes a core crystallizer and an external crystallizer. The same as the crucible, its production material is red copper, which has fast heat conduction, and can quickly take away the heat in the crucible through circulating cooling water, ensuring deep penetration of the inner wall surface of the ingot, improving the surface quality of the inner surface of the cast tube billet, and reducing casting defects.

[0032] The structure of the core crystallizer in this embodiment includes an outer casing 1, a water guide pipe 2 and a water inlet pipe 3; the number of water inlet pipes 3 is 2, and the number of water guide pipes 2 is 2; The water pipes 2 are distributed symmetrically along the inner wall of the outer casing 1 . The shape of the outer casing 1 is an inverted U shape, and horizontal casings facing outward are respectively arranged...

Abstract

The invention relates to a core crystallizer for casting hollow ingots, which comprises an outer casing, a water guide pipe and a water inlet pipe; one side of the water guide pipe communicates with the water inlet pipe, and the other side of the water guide pipe The side communicates with the outer casing; wherein, the number of the water inlet pipes is at least 2, and the number of the water guide pipes is at least 2, and the matching water inlet pipes and water guide pipes are arranged along the inner wall of the outer casing. Symmetrical distribution. The present invention also relates to a water-cooled crystallizer comprising the above-mentioned core crystallizer and an external crystallizer. The invention optimizes and improves the water inlet mode and water flow guide by designing the structure of the core crystallizer, and realizes the simple assembly of the core crystallizer, which can be used for the casting of titanium hollow ingots, and can also be used for electron beam melting of other metals in the cooling bed The hollow ingot is cast during the process, and the cooling effect can be adjusted according to the water pressure, so that the product can be fully cooled during the ingot casting process without affecting the quality of the product.

Description

technical field [0001] The invention relates to the technical field of water-cooled crystallizers, in particular to a core crystallizer for casting hollow ingots and a water-cooled crystallizer containing the core crystallizer. Background technique [0002] Cooling bed electron beam smelting is a metallurgical technology that combines electron beams with a cooling bed and smelts under high vacuum. By separating raw material melting and ingot casting, the purpose of degassing, refining and obtaining higher ingot quality is achieved. [0003] The traditional methods of obtaining hollow ingots through cooling bed electron beam smelting mainly include the following two methods: one is casting solid ingots, which are obtained by machining in the later stage, and the loss is relatively large in this way; the other is adding A graphite rod or water-cooled copper tube. The first method has a large machining loss, which seriously reduces the use efficiency of the product, and the s...
