Preparation process of intermediate alloy containing volatile element

Abstract

The invention discloses a preparation process of intermediate alloy containing a volatile element and relates to the technical field of alloy. The process comprises the following steps: 1), burdening intermediate alloy components and parent metal according to a design proportion, smelting and pouring to form cast blank in a furnace; 2) smashing the cast blank and grinding to obtain smashed particles; and 3) uncoiling a metal strip coil, rolling the middle of the width of the metal strip coil along the unfolding direction of the metal strip coil to form a U shape, putting a powder material in a U-shaped groove, carrying out roll forming and pressing on the strip edge of the alloy to form a tube shape so as to obtain wire coil. According to the practical demand, the wire coil is uncoiled and alloy line is continuously added or the required alloy line is cut to be added into a smelting process so that the problem that the intermediate alloy containing less element, especially volatile burning loss element can not be continuously added in the smelting process, or the quantitative addition of the intermediate alloy is not correct is solved, thereby well producing the blank with uniform components for a manufactured lumber.

Description

technical field [0001] The invention relates to the field of alloy technology, in particular to a new process for preparing a master alloy containing volatile elements. Background technique [0002] Alloys containing Zr, Co, Bi, Be and other volatile elements, such as C15000 series, C17000 series and C18100 series copper-zirconium alloys, C17000 series beryllium bronze alloys, and even copper alloys containing Mg; 2 series such as 2004, 2014, 2017A , 3011 and other series, 5025, 5249, 5180 and other 5 series, 6007 and other 6 series and 7108~7122 and other 7 series aluminum alloys, all contain varying amounts of trace volatile alloy components, such as Zr elements, and even toxic and volatile elements Be. Although these elements are in small amounts, they have a huge impact on the properties of the material, and the master alloy is expensive. Since these elements, except Mg, generally have a high melting temperature and their sublimation temperature in air is low, they are...

Problems solved by technology

[0006] In order to solve the problem of uneven addition of copper-zirconium, copper-magnesium, copper-cobalt, aluminum-zirconium, aluminum-beryllium and other master alloys, the present invention provides a new process for the preparation of master alloys containing volatile elements to solve the problem of containing a small amount of elements, especially It is the problem that the intermediate alloy of volatile burning elements cannot be continuously added to the smelting process, or the quantitative addition is inaccurate, and it is better to produce billets for processing materials with uniform components.
