In order to ensure smooth casting and rolling into qualified steel, a certain amount of deoxidizer is added to the molten steel for deoxidation at the end of smelting or during tapping, and at the same time, an appropriate amount of alloy is added to adjust the chemical composition according to the requirements of the steel specification. Generally, there are silicon-manganese alloys, Ferro-silicon, ferro-manganese, ferro-aluminum, silicon-aluminum-barium-calcium, etc., are reducing agents that prevent steel from being oxidized again at high temperatures;

Ferrosilicon is an ferro-silicon alloy made of semi-coke, iron oxide sheet and silica as raw materials and smelted in an electric furnace. Ferrosilicon is mainly used as a deoxidizer and alloying agent in steelmaking. The main factors affecting the price of ferrosilicon are as follows:

Silicon carbide, also known as moissanite, is a material smelted at high temperature in an electric cathode furnace. Such substances also exist in nature, which are very rare (such as moissanite). Because of its stable chemical properties, good wear resistance, and high thermal conductivity, it is widely used in various production and living fields such as electrical, telecommunications, and aerospace. Here are five basic uses for this material.

Ferrosilicon powder is a ferroalloy composed of iron and silicon, which is then ground into powder and used as a deoxidizer for steelmaking and ironmaking. Ferrosilicon powder has a wide range of uses, let's see what you know:

Off grade silicon metal like its name means, is unqualified metallurgical si metal. Silicon content used to be 93% min but recent years with advanced production technique, the purity of off grade silicon metal became higher than 96%, 97%. Because it’s relative high purity and surprising cheap price. It is very suitable to replace model Si 553 in some area. In some Aluminum Alloy model, only small quantity of silicon is needed. And some model didn’t require very strict Silicon or Fe, Ca content. So off grade silicon is very good substitute and very efficiency material to save cost . Off grade s

Silicon-calcium alloy is a new type of ferroalloy product. Silicon-calcium alloy is a perfect combination of silicon and calcium elements. It has a strong deoxidation force during steelmaking. Because it has an affinity with oxygen, the molten steel is deoxidized at the same time. No splashing greatly reduces the chance of staff being scalded,
