Production device for metal fibers

Abstract

The invention provides a production device for metal fibers. The device comprises a metal melting system used for melting a metal and a vacuum system, and is characterized by also comprising a heat preserving and pressurizing system and a fiber cooling system, wherein the heat preserving and pressurizing system is connected with the metal melting system and is used for performing heat preservation and pressurization on molten metal; the fiber cooling system is connected with the heat preserving and pressurizing system and is used for receiving and cooling the molten metal ejected from the heat preserving and pressurizing system; and the vacuum system is connected with the metal melting system and the heat preserving and pressurizing system so as to provide vacuum environments for the metal melting system and the heat preserving and pressurizing system. By using the device, the requirements on purification and melt protection are met; fiber forming can be controlled; and the aims of stable production and preparation of high-quality metal fibers are fulfilled.

Description

technical field [0001] The invention relates to a production device for metal fibers, in particular to a device for purifying low-melting active metals and producing high-quality metal fibers. Background technique [0002] Metal fiber is a new type of material integrating a variety of special properties. It has high strength, high elastic modulus, and excellent electrical conductivity, thermal conductivity, and wear resistance. Therefore, the use of metal fibers continues to expand, and the amount is growing rapidly, and is widely used in aerospace, automobile, construction and other industries. [0003] There are three main methods of manufacturing metal fibers: cutting method, drawing method and melting method. At present, a considerable part of the fibers used in China are produced by cutting methods. This kind of fibers has poor dimensional accuracy, irregular shape, and poor quality, which seriously affects the use effect. Although the surface quality of the fiber pro...

AI Technical Summary

Problems solved by technology

Its biggest disadvantage is that the metal melt cannot be effectively purified, and it cannot effectively protect active metals, resulting in low quality fibers

Moreover, due to the existence of a large number of oxidation and inclusions, the nozzle is easy to block, and the work efficiency is very low.

With the development of science and technology, the requirements for fiber purity and comprehensive performance have been improved, and the existing technology can no longer meet the needs of producing high-quality fibers.
