Production method of metal fibre

Abstract

The invention provides a production method of metal fibre, comprising the following steps: 1) using a vacuum system to provide vacuum environment for a metal melting system and a heat-preservation pressurization system; b) using the metal melting system to melt metal; c) pouring molten metal into the heat-preservation pressurization system for heat-preservation pressurization; and d) vertically injecting the molten metal to a fibre cooling system to generate the metal fibre. The invention satisfies the requirements of purifying and protecting the molten liquid, can control fibre shaping and obtains the purposes of stable production and preparation of the high-quality metal fibre.

Description

technical field [0001] The invention relates to a production method of metal fibers, in particular to a method 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 prod...

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.
