Ferrosilicon natural block can improve the shape of inclusions and reduce the content of gas elements in molten steel. It is a new technology to improve steel quality, reduce costs and save iron. It is especially suitable for the deoxidation requirements of continuous casting molten steel. Practice has proved that it not only meets the deoxidation requirements of steelmaking, but also has desulfurization performance and has the advantages of large specific gravity and strong penetrating power. It is an ideal alloy material.
Ferrosilicon natural block is a common metallurgical material in the industrial field. It is mainly used for the smelting of metals. It is often used as an additive and has deoxidation and inoculation effects.
Cast iron is an important metal material in modern industry. It is cheaper than steel, easy to melt and smelt, has good casting properties and is much better than steel in earthquake resistance. In particular, the mechanical properties of ductile iron reach or are close to those of steel.
Adding a certain amount of ferrosilicon to cast iron can prevent the formation of carbides in the iron and promote the precipitation and spheroidization of graphite. Therefore, ferrosilicon is an important inoculant and spheroidizing agent in the production of ductile iron. Ferrosilicon natural blocks are very convenient to use. Generally, we do not need to perform special processing on this material, but we must also distinguish it according to different applicable objects.
We are a supplier of metallurgical materials. The products processed and sold by the company can be divided into many types, which meet many needs in the smelting industry. If you are interested in learning more, please call us directly.
