Abstract

The invention discloses a method for preparing an alloy manganese rod. The method comprises the following steps that copper, sodium and manganese are added into an industrial furnace for smelting; manganese ingots are gradually added until the component requirement is met, wherein the mass percentage content of copper is 0.1-2%, the mass percentage content of sodium is 0.05-0.1%, and the balance the manganese; a refining agent is added, and stirring and refining are performed; heat preservation is performed on the refined alloy melt, and the temperature is controlled to be 450-500 DEG C; and pressurization extrusion is performed to obtain the alloy manganese rod. The alloy manganese rod obtained through the preparation method can be drawn into different lengths, diameters and shapes according to requirements, the mechanical property and the corrosion resistance of the alloy manganese rod are equivalent to those of a brass rod, and the cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of manganese rod preparation, in particular to a method for preparing alloy manganese rods. Background technique [0002] Brass rods are widely used in air-conditioning pipes, refrigerator pipes, oil pipes, water supply pipes and various mechanical supporting materials, but the price of copper remains high, resulting in a high cost of brass rods. Replacing brass rods with a less expensive metal rod has become a common challenge in the industry. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing alloyed manganese rods. The alloyed manganese rods obtained by the preparation method can be drawn into different lengths, diameters, and shapes according to requirements, and their mechanical properties and corrosion resistance are equivalent to those of brass rods. Dropped significantly. [0004] The invention provides a method for preparing manganese all...
