The purpose of using master alloys are:
(1) Obtain metal materials with precise chemical composition and uniform distribution. For example, adding elements with less content in the metal material components can improve the uniformity of the added elements in the material. For example, use vanadium aluminum alloy to add vanadium to smelt Ti-6A1-4V alloy.
(2) Adding elements with high chemical activity, low melting point and volatile elements. Such as intermediate alloys of boron, calcium, magnesium, etc. The use of a master alloy can reduce the burning loss of the elements when they are added, and obtain a stable alloy composition and a higher element yield.
(3) Add high melting point metal. Such as tungsten, molybdenum, titanium, niobium, chromium and other intermediate alloys, can reduce the melting temperature, shorten the smelting time of metal materials and lower the smelting temperature.
(4) The use of master alloy can add multiple elements at the same time, so that the refining and alloying of the smelted alloy can be completed at the same time. Simplify the smelting operation and shorten the refining time.
(5) The use of pure master alloys can reduce the impurity content in metal materials. For example, master alloys with "VQ" grade are used for vacuum smelting.
(6) Reduce the production cost of metal materials. The requirements for the master alloy are as low as possible melting point; uniform chemical composition, small segregation; no visible non-metallic inclusions; low gas content; impurity content must meet the requirements of the metal material to be smelted; easy to be broken and stored in the air without deterioration.
