Ferro Tungsten

HGS, as one of ferro tungsten suppliers, provides ferro tungsten for sale. Ferrotungsten belongs to the ferroalloy series. Ferro tungsten is an alloy composed of tungsten and iron. It is used as an alloy additive in steelmaking. The commonly used tungsten iron has two kinds of 70% tungsten and 80% tungsten. Tungsten iron smelting with electric furnace, because of the high ferro tungsten melting point, can not release liquid, so the use of the agglomerating method or iron production. Before 1930s, small (100 ~ 500 KVA) single-phase electric arc furnace was generally used for agglomerating smelting, and later, the three-phase electric furnace was used, and the iron extraction process was developed.

Ferro Tungsten Uses

As an additive in the production of ferro alloys types metals, tungsten-iron will give the new alloy some desirable properties.

One of the main benefits of adding tungsten-iron to alloys is to increase the melting point of the alloys, making them suitable for aerospace applications as well as welding applications.

In addition, by adding tungsten-iron to the alloy, one can take advantage of the unique electrical properties of tungsten as a conductor.

Ferro Tungsten Production Process

Ferro Tungsten Production Process

The basic ferro tungsten production process is: mining the mineral, changing it into oxides of tungsten, then adding hydrogen or carbon to heat it in order to produce a powder shape for mixing with the iron. Ferro tungsten is usually packaged in 5mm to 100mm particle size and 100kg iron drums. Ferro tungsten is melted by electric furnace. Due to its high melting point, it cannot be released in liquid state, so it is produced by agglomeration method or iron extraction method. Before the 1930s, small-scale (100~500 kVA) single-phase electric arc furnaces were generally used for agglomeration smelting, and later, three-phase electric furnaces were used, and iron extraction methods were developed.

Features of Ferro Tungsten

Features of Ferro Tungsten

  • 01.

    The refractory metal products are particularly important that tungsten has a good influence on the mechanical properties of steel at high temperature, which can improve the heat resistance and tempering stability.

  • 02.

    Because of the ferro tungsten price, tungsten can not only reduce the elongation of steel, but also increase the strength limit and yield point of steel, and improve the hardness and wear resistance of steel.

  • 03.

    In steel, tungsten combines with carbonation to form carbides, and partially dissolves into iron to form solid solutions. Tungsten has little effect on the hardenability of steel. Its main use in steel is to increase the tempering stability, red hardness and thermal strength of steel, and because of the formation of special carbide and increase wear resistance, so it is used in tool steel, high speed steel, hot forging die steel and so on.
