Ferroalloy, in a broad sense, refers to a product that is added to molten iron as a deoxidizer or elemental additive during steelmaking to make steel possess certain characteristics or meet certain requirements. A master alloy consisting of iron and one or more elements, mainly used in steel smelting. In the iron and steel industry, all intermediate alloys used for steelmaking, regardless of whether they contain iron or not (such as silicon calcium alloys), are commonly referred to as "ferroalloys.". Traditionally, certain pure metal additives and oxide additives are also included.

The reason why silicon-carbon alloy is called silicon-carbon alloy is because its main elements are silicon and carbon. Carbon plays a very important role in the performance of cast iron, avoiding cast iron defects, and reducing waste. The size of carbon also affects the flow of cast iron. Very large, if you want to improve the fluidity of cast iron, you can add a lot of carbon. In addition, Si is an element that strongly promotes the crystallization of iron-carbon in a stable system, and promotes the precipitation of high-carbon phases in the primary crystal, eutectic and eutectoid transforma

The cored wire is to crush various additives (deoxidizers, desulfurizers, modifiers, alloys, etc.) Composite material with any length.

Silicon calcium alloy is a composite alloy material, which is mainly composed of silicon, calcium, iron and other trace elements. In the steelmaking industry, silicon calcium alloys are mainly used as composite deoxidizers and desulfurizers. However, in addition to silicon calcium alloys, there are other types of deoxidizers for steelmaking on the market, and the competition is very fierce. However, silicon calcium alloys have not been greatly affected under such circumstances, and still rely on their own strength. It has won the recognition of many users.

The role of silicon in promoting graphitization in cast iron. In cast iron, silicon is an alloying element that promotes graphitization, and its ability to promote graphitization is three times that of nickel and five times that of copper.

The quality of different recarburizers is not the same, for example: graphite recarburizer, coal recarburizer, etc., they have different places in terms of basicity, absorption rate, price, advantages and disadvantages, etc., although the differences Not very big, but if the application is not good, it will also affect their carburizing effect.
