Method and device for continuously preparing superfine amorphous alloy wire

Abstract

The invention relates to a method and device for continuously preparing a superfine amorphous alloy wire. The device comprises a vacuum system, an elevating system, an alloy leading-in system, a heating system, a cooling system and a wire winding system. The method is characterized by comprising the following steps of: smelting proportioned alloy and suction molding; cutting into an ally ingot with the length of 4-10 mm and an alloy bar with the length of 10-70 mm; placing the alloy ingots at the bottom of a glass test tube; connecting the alloy bar with a leading-in bar; connecting the glasstest tube with the bottom end of a bellow; after vacuumizing and charging argons, induction heating to enable alloy at the bottom of the test tube to be smelted and the bottom of the glass test tube to be softened therewith; dragging out a fine wire from the bottom of the glass test tube by using a glass bar with a tip; and winding the fine wire cooled with water spray on a wire winding wheel through the guide of a guide wheel. In the preparation process, an elevating bar is descended, the welded bellow is lengthened, the glass test tube is descended, and consumed glass is complemented; when a lead-in device is rotated, the lead-in bar and the alloy bar are continuously descended, and the consumed alloy is complemented; and the aim for continuously preparing the superfine amorphous alloy wire is realized.

Description

technical field [0001] The invention belongs to direct forming and near-net forming technology for preparing amorphous alloy wire, and mainly provides a method and device for continuously preparing amorphous alloy wire. Background technique [0002] Amorphous alloy wire is a new type of amorphous material following the emergence of amorphous thin strips. It has special mechanical and physical properties: high tensile strength, large elastic limit, unique magnetic effects, including giant magneto-impedance effects and large Buckhau Sen effect etc. Therefore, amorphous alloy wire can be used as both structural and functional materials. The preparation of amorphous alloy wire with high roundness and good uniformity has become a key technology for research by various countries. [0003] The existing preparation methods of amorphous alloy wire include glass coating method, inner circle water spinning method and melt drawing method. The cooling capacity of the wire produced by ...

Problems solved by technology

[0004] At present, most of the glass coating devices at home and abroad cannot realize the continuous replenishment of alloy raw materials during the preparation process, so they cannot achieve the purpose of continuously preparing amorphous alloy wires; the devices that realize continuous feeding are often unable to be isolated from the atmosphere, and It can only be protected by argon in the open glass test tube, and the purpose of continuous preparation cannot be achieved for alloys that are prone to high temperature oxidation
