Aluminium-silicon alloys prodn - using a charge contg petroleum coke and amthracite

摘要

alloys, suitable as deoxidation alloy for steel, or for prodn. of Si, SiCa and Fe-poor iron alloys, are obtained by using a charge comprising a mixture of petroleum coke and anthracite at a ratio of anthracite to petroleum coke of 2.85 to 0.7-1. referred to the non-volatile carbon. The charge pref. contains in addition a binding agent composed of sulphite-alcohol extract based on Na, Mg or ammonium cations and may also contain chlorides and fluorides of alkali-or alkaline earth metals in amounts of 3% of total wt. of charge.
