FLUX FOR ELECTROSLAG REMELTING Russian patent published in 2013 - IPC C21C5/54 C22B9/10 C22B9/18 

FIELD: metallurgy.

SUBSTANCE: flux contains calcium oxide, aluminium oxide, and also partially silicon oxide and magnesium oxide in the form of slags from production of carbonaceous ferrochromium and silicocalcium, the missing magnesium oxide is introduced in the form of baked magnesite, the missing silicon oxide - in the form of quartz sand. At the same time the components are taken at the following ratio, wt %: slag of carbonaceous ferrochrome production 33-35, slag of silicocalcium production 50-52, magnesite 11-15, quartz sand 3-5. At the same time slag of carbonaceous ferrochrome production contains the following components, wt %: silicon oxide 30-35, calcium oxide 4-6, aluminium oxide 20-30, magnesium oxide 30-35, and slag of silicocalcium production contains the following components, wt %: silicon oxide - 30-35, calcium oxide - 63-68, aluminium oxide - 5-10, magnesium oxide - 0-1, calcium fluoride - 2-10.

EFFECT: invention makes it possible to avoid expensive technologies for manufacturing of each components within a flux.
