A water-cooled composite mold for arc melting drop casting

Abstract

The invention discloses a water cooling assembling die for electric arc melting drop casting. The water cooling assembling die comprises an outer die body and an inner die body wrapped with the outerdie body. A cavity is formed in the top of the outer die body and communicates with the top of an inner cavity of the inner die body. Water cooling flow guiding groove perpendicular to the bottom faceis formed in the side walls of the outer die body. Through holes are formed in the side walls of the outer die body and penetrate through the side wall of the outer die body to communicate with the water cooling flow guiding groove. A vent hole is formed in the bottom of the outer die body and communicates with the bottom of the inner die body. Through the water cooling assembling die for electric arc melting drop casting, the problems that in the prior art, electric arc melt ingots are simplex in shape, and cooling speed cannot be controlled are solved. The die is simple in structure, the outer die body and the inner die body are matched closely, the inner die body is wrapped with the outer die body and can be replaced for use, the boundary dimensions of samples are replaced while the water cooling outer die body remains unchanged and can continue being used, the die application efficiency is improved, and the die application cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of mechanical mold preparation, and in particular relates to a water-cooled composite mold for arc melting drop casting. Background technique [0002] Arc melting is an important alloy melting technology, which has important applications in the preparation of superalloys, eutectic autogenous composite materials, magnetic materials and other structural and functional materials. However, most of the ingots prepared by arc melting are in the shape of button ingots. Under the contact action of the water-cooled copper mold, the button ingots are cooled rapidly after smelting, and the cooling rate is extremely uneven and uncontrollable on the surface and core of the samples. Cooling rate is an important technical parameter for alloy smelting. Reasonable control of cooling rate is of decisive significance for obtaining alloy materials with superior structure and performance, but arc melting technology cannot meet t...
