What is the processing technology of medium carbon ferromanganese?
The processing technology of medium carbon ferromanganese mainly includes four links: smelting, casting, forging and heat treatment.
The first is smelting. Medium carbon ferromanganese is usually smelted by blast furnace coking method, and the raw materials are mainly composed of manganese ore, coke and limestone. During the smelting process, the raw materials are added to the blast furnace, and the useless impurities in the furnace are burned out by high-temperature combustion, leaving the manganese iron alloy liquid.
Next is casting. After the smelting is completed, the melted medium carbon ferromanganese is poured into the casting machine, cast through the mold, and after it cools and solidifies, it is taken out to form a medium carbon ferromanganese casting.
The second is forging. Forging is a method of heating the medium carbon ferromanganese casting with a molten iron hammer or a hydraulic press and then plastically deforming it. The main purpose is to change the internal structure of the casting and improve its mechanical properties. After forging, the structure of the medium carbon ferromanganese parts is denser and the mechanical properties are better.
The last is heat treatment. The mechanical properties of medium carbon ferromanganese can be improved by heat treatment. The heat treatment method usually used is tempering. After the forged medium carbon ferromanganese parts are heated to a certain temperature, they are kept warm for a period of time and then cooled to room temperature. Through heat treatment, the hardness, strength and toughness of medium carbon ferromanganese parts can be improved.
In general, the processing technology of medium carbon ferromanganese mainly includes four links: smelting, casting, forging and heat treatment. Through the processing of these links, medium carbon ferromanganese products with dense structure and excellent performance can be obtained.
