Equipment for producing aluminum alloy hollow casting ingot and method of equipment

Abstract

The invention relates to the technical field of aluminum alloys, in particular to equipment for producing an aluminum alloy hollow casting ingot and a method of the equipment. The equipment for producing the aluminum alloy hollow casting ingot comprises a core die, a crystallizer, a bracket and a dummy ingot, wherein the core die is positioned at the center of the crystallizer and is concentric with the crystallizer; the bracket arranged on the crystallizer is used for supporting the core die; the dummy ingot is arranged at the lower part of the core die; a space between the core die and the crystallizer is a die cavity; the core die is designed into a taper with a large upper part and a small lower part; and the size of the taper is 1-30 degrees; a cooling system and a lubricating system are arranged in the core die; a coil is arranged in a water chamber of an aluminum sleeve of the crystallizer; and a shunt and a stop block are arranged on the crystallizer. According to the equipment for producing the aluminum alloy hollow casting ingot and the method for the equipment disclosed by the invention, a friction force between the casting ingot and the die core in the hollow casting process of the aluminum alloy is reduced and the core locking and breakout are avoided.

Description

technical field

[0001] The invention relates to the technical field of aluminum alloys, in particular to a device for producing aluminum alloy hollow ingots and a method for using the same. Background technique

[0002] Aluminum alloy pipes are widely used in electric power, construction and other industries. There are two main production methods:

[0003] 1. Casting produces solid ingots, and pipes are produced by rolling or extrusion, but such a production process has many procedures and low metal utilization;

[0004] 2. Casting produces hollow ingots, and pipes are obtained by extrusion, which has fewer process steps and high metal utilization.

[0005] Therefore, casting and producing hollow ingots is the preferred process for producing aluminum alloy pipes. At present, the main method of producing aluminum alloy hollow ingots is semi-continuous casting. Semi-continuous casting equipment usually consists of core mold, crystallizer and dummy ingot. At the beginning o...
