Abstract

The invention discloses a preparation method of Monel metal for pressed plates. The preparation method is implemented according to the following process: (1) Monel metal raw materials are prepared; (2) refractory material crucibles for smelting alloys are prepared; (3) a vacuum induction smelting furnace is used for vacuum induction smelting to obtain Monel metal ingots; (4) the ingots are machined; the head loose and empty parts are cut off; and the surfaces are polished without scales; (5) the vacuum arc remelting is performed; and (6) the surface layers of the Monel metal ingots are removed through lathe machining. The method guarantees precise metal components, and prevents the metal element oxidation problem; and through the subsequent vacuum arc remelting process, the component segregation is further reduced, and the metal structure uniformity is improved.

Description

technical field [0001] The invention belongs to the technical field of alloy preparation, and in particular relates to a preparation method of Monel alloy used for pressing plates. Background technique [0002] Monel alloy is a kind of nickel-based alloy. Its main components are Ni and Cu. In addition to the main elements Ni and Cu, it usually contains other alloying elements, such as iron, manganese, silicon, aluminum, sulfur, and carbon. etc., they play the role of solid solution strengthening, second phase strengthening, grain boundary strengthening, etc., and have good corrosion resistance to halogen elements and their compounds, non-oxidizing acids, alkalis, salts, etc., and can also withstand hydrogen fluorine Corrosion of acid, acetic acid, reducing inorganic acid, organic acid and other media; at the same time, Monel alloy also has excellent comprehensive properties such as good formability, easy cutting and welding. In 1906, Monel alloy was successfully developed b...
