Manganese and silicon are the main alloying elements used in carbon steel. Manganese is one of the main deoxidizers in the steelmaking process. Almost all steel types require manganese for deoxidation. Because the oxygen product generated when manganese is used for deoxidation has a low melting point and is easy to float; manganese can also increase the deoxidation effect of strong deoxidizers such as silicon and aluminum.

Silicon-manganese alloy is mainly used as an intermediate material for deoxidizers and alloying agents in steel production, and is also the main raw material for the production of medium and low carbon ferromanganese. Silicon-manganese alloy is an alloy composed of manganese, silicon, iron, a small amount of carbon and other elements. It is an iron alloy with wide uses and large output.

Classification of ferrosilicon:

　　Ferrosilicon 75, usually ferrosilicon containing 75 per cent silicon, with low carbon, phosphorus and sulphur content.

　　Ferrosilicon 72, usually 72% silicon content of ferrosilicon, carbon, sulfur, phosphorus content in the middle.

　　Ferrosilicon 65, 65% silicon content of ferrosilicon, carbon, sulfur, phosphorus content is relatively high.

Silicon has a wide range of applications, but in calcium-silicon alloys, we only use it extensively in the steelmaking industry. The silicon element inside the calcium-silicon alloy can reduce the molten steel very well.

This article mainly introduces the price of ferrovanadium 50 in China between November 1st and November 20th.

Ferrotungsten is an alloy consisting of the elements tungsten (W) and iron (Fe). Ferro-tungsten alloys are usually named based on their tungsten content, for example, tungsten-iron alloys can have tungsten content of 70% or higher.
