Abstract

The invention relates to a method for producing Monel alloy ingots by using horizontal continuous casting, belonging to the technical field of smelting. The method comprises the following steps: selecting and allocating materials, smelting, carrying out rapid ladle analysis, deoxidizing, degassing, measuring the temperature, releasing to a heat preservation continuous casting furnace, refining under the protection of argon, measuring the temperature, carrying out continuous casting and cutting on line so as to obtain the products, namely, the Monel alloy ingots. To overcome the defects that the vacuum sensing furnace smelting is complex in operation and high in cost, and in non-vacuum sensing furnace smelting, cracks generally happen in machining such as later extrusion, casting, rolling and the like, the yield is low, and the like, due to the fact that products absorb the gas in the smelting process, the invention provides the method for producing the Monel alloy ingots by using horizontal continuous casting, by utilizing such method, the production cost is saved, the effect is identical to vacuum smelting, and industrial popularization and application are facilitated.

Description

technical field [0001] The invention relates to a method for producing Monel alloy ingots through horizontal continuous casting, which belongs to the technical field of smelting. Background technique [0002] Monel alloy has extremely good corrosion resistance, and it can show corrosion resistance to halogen elements, neutral aqueous solution, caustic alkali solution at a certain temperature, and medium-temperature dilute hydrochloric acid, sulfuric acid, phosphoric acid, etc., and its corrosion resistance at all concentrations It is also corrosion-resistant in hydrofluoric acid at low temperature and high temperature, so it is widely used in petroleum, chemical shipbuilding, pharmaceutical, and electronic departments. Such as nuclear industry manufacturing uranium refining and isotope separation equipment, seamless water pipes, steam pipes, seawater exchangers and evaporators in power plants, sulfuric acid and hydrochloric acid environments, crude oil distillation, pump sha...
