Abstract

The invention relates to a method for producing an aluminum-manganese-titanium alloy. Batch mixing of aluminum powder and medium manganese powder is carried out, the mixed aluminum powder and medium manganese powder are pressed into metal blocks through a briquetting machine, and the metal blocks are contained in a crucible of a medium-frequency induction furnace; the temperature of the medium-frequency induction furnace rises, so that materials are completely melted in the medium-frequency induction furnace; and edged titanium sponge is added to continuously conduct melting, the materials are discharged out of the furnace after even melting is carried out, and the aluminum-manganese-titanium alloy is obtained. The method has the beneficial effects that the process is simple, and operation is convenient; and the aluminum powder, the medium manganese powder and the edged titanium sponge serve as raw materials, and waste in the production process of metallurgy industries is sufficiently used, so that the method is low in cost, stable in product quality, environment-friendly, and suitable for industrial production

Description

technical field [0001] The invention relates to a production method of a composite alloy, which mainly uses medium manganese powder, edge titanium and aluminum powder produced in the production process of metallurgical enterprises as raw materials, and uses a medium frequency induction furnace to produce an aluminum manganese titanium alloy. Background technique [0002] Aluminum-manganese-titanium series alloy is a composite deoxidizer, which has the advantages of strong deoxidation ability and easy removal of deoxidized products. The alloy contains titanium element, which better solves the problems of easy pulverization and short storage time of aluminum-manganese alloy. It is the future One of the main varieties in line with the development of deoxidizers. [0003] CN 101724732 A discloses a "low-carbon, low-silicon, aluminum-manganese-titanium alloy used for deoxidation and alloying of molten steel". The method uses pure aluminum ingots, metal manganese, ferro-titanium a...
