Abstract

A casting slag composition consists of 10-60% by wt. of alumina, 10-60% of calcium oxide, 2-20% of titania, 5-50% of an alkali metal or alkaline earth metal fluoride, up to 10% each of magnesia, and sodium oxide, and optionally up to 5% of silica. The fluoride may be cryolite, fluorspar, or sodium fluoride but other alkali metals are referred to CaO, Al2O3, and MgO (if present) should constitute 75% of the total, and the fluorides plus Na2O should not exceed 25%. The composition should not contain more than 1% of Mn, Fe, Cn, Ni, and Cu; boron compounds should be absent. Na2O may be added in the form of soda ash, and MgO as dolomite. The slag melts at 1280 DEG C. and has no thermal asserts from 1650 DEG C. down to its melting point and particularly suited to casting nickel alloy ingots, e.g. Ni alloys containing 7% by wt. or more of nickel together with oxides of Al, Ti, Mg or Zn, which contribute to age hardening and de-oxidising. The molten alloy is turned into a mould containing molten slag used in proportions of 18 Kg.slag to 1000 Kg. metal, at 1600 DEG C. After cooling to red heat, the mould is stripped, leaving an ingot ready for forging.ALSO:A casting slag composition consists of 10-60% by weight of alumina, 10-60% of calcium oxide, 2-20% of titania, 5-50% of an alkali metal or alkaline earth metal fluoride, up to 10% each of magnesia and sodium oxide, and optionally up to 5% of silica.

CaO, Al2O3, and MgO (if present) should constitute 75% of the total, and the fluorides plus Na2O should not exceed 25%. The composition should not contain more than 1% of Mn, Fe, Cr, Ni and Cu; boron compounds should be absent. Na2O may be added in the form of soda ash, and CaO as dolomite. The slag melts at 1260 DEG to 1280 DEG C. and has no thermal arrests from 1650 DEG C. down to its melting point. It is especially suited to casting nickel alloy ingots using 18 Kg slag to 1000 Kg of the molten alloy.
