Title:
MANUFACTURE OF ALUMINUM-SILICON ALLOY
Document Type and Number:
Japanese Patent JPS5976836
Kind Code:
A
Abstract:
In a method of manufacturing aluminium-silicon alloy from natural mineral containing alumina and silica and carbon powder, the natural mineral in powder form is injected together with a reducing agent in the form of a carbon carrier, with the aid of a carrier gas into a plasma gas produced in a plasma generator. The mineral thus heated is then introduced, together with the reducing agent and the energy-rich plasma gas, into a reaction chamber surrounded substantially on all sides by solid reducing agent in lump form. Examples of the natural mineral include andalusite, cyanite, silimite, nepheline, quartz, clay containing alumina, such as bauxite, and mixtures of two or more of these minerals.
