Abstract
The invention relates to an interalloy for smelting. A vacuum aluminium-molybdenum-silicon alloy, is charactrized in that the alloy has close structure without slag inclusion and segregation, comprising, based on weight percentage, Mo of 40-63%, si of 4.0-5.0%, O of not more than 0.015%, H of not more than 0.002%, N of not more than 0.006%, C of not more than 0.06%, Fe of not more than 0.10%, and the residual is Al. The invention solves the technical problem that the non-vacuum aluminium -silicon alloy has segregation, slag inclusion, high content gas impurity without close structure, secondly solves the technical problem of low content of molybdenum in the alloy.
Description
Technical field: [0001] The present invention relates to alloys, in particular to vacuum-grade aluminum-molybdenum-silicon alloys used as master alloys for smelting. Background technique: [0002] Alloy materials change rapidly with the development of smelting technology and market demand. In the smelting process of alloy materials, intermediate alloys are often used to make the smelting process stable and easy to control the operation. On June 22, 2005, the publication number was CN1629331A, and the invention patent application titled "Aluminum Molybdenum Silicon Master Alloy and Its Preparation Method" disclosed a composition by weight percentage: Mo38-48%, Si3.5 ~4.5%, Al is the balance of aluminum molybdenum silicon master alloy, using the magnesium scrap furnace ignition smelting method, the weight composition of the ingredients is based on Al being 1kg, industrial Si is 0.034~0.044kg, MoO 3 0.781~0.935kg, CaF 2 0.36~0.42kg, KClO 3 It is a preparation method in whic...
