ferroalloy raw material supplier

HC Ferro Silicon comes from leftover material of silicon metal producing, a caking at bottom of the furnace. Elemental silicon content is usually between 40-70% and carbon content is 10-25%. High carbon silicon is normally used as a low cost substitute of ferrosilicon, silicon carbide and recarburizer which effectively reduce the cost of steelmaking. silicon carbon alloy application Silicon carbon alloy is a new alloy of alloys for converters. It can replace ferrosilicon, silicon carbide, carbon reductant, reduce the amount of deoxidizer, and be used in converter smelting deoxidation alloying process. The effect is stable, chemical composition and mechanical properties of steel. The internal control quality is superior to the traditional process. Its characteristics: improve the quality of molten steel, improve product quality, improve product new energy, reduce the amount of alloy added, reduce steelmaking costs, and increase economic benefits. silicon c...

Ferrosilicon powder is a kind of ferroalloy, ferrosilicon powder is usually processed by grinding machine to ferrosilicon natural block, ferrosilicon powder is more convenient than ferrosilicon natural block to use better effect, because of its shape advantage can be more thorough chemical reaction in the actual use process, so the specific application of ferrosilicon in what fields? Application in cast iron industry Ferrosilicon powder can be used in cast iron as inoculation agent and spheroidizing agent. Ferrosilicon powder can effectively improve the properties and seismic resistance of cast iron, and greatly improve the mechanical properties of ductile iron. Application in ferroalloy industry Ferrosilicon powder can be used as reducing agent in the production of ferroalloy. The internal silicon element has affinity with oxygen, and the low carbon content of high-silicon ferrosilicon powder is a common reducing agent in the production of low-carbon ferroalloy ...

We all know that silicon carbide is often essential for ferroalloy additives on casting, hot metal he can effectively improve flow performance, the effect of casting, greatly increasing, at the same time can also play a role, prompt production of eutectic pellets, anyhow silicon carbide is frequently used in smelting casting material, since silicon carbide for casting is very important so the development of a foundry casting silicon carbide is very logical, so the research and development production for casting of silicon carbide silicon carbide manufacturer for casting tool has specificity, but many of the foundries in use are not particularly understand when casting of silicon carbide,So you often ask silicon carbide manufacturers how to cast silicon carbide? We consulted the professional manufacturer of silicon carbide henan star metallurgical teacher told us that the first casting silicon carbide is divided into 70 90 # 88 # # silicon carbide, silicon carbide, ...

As we all know, ferrosilicon is an iron alloy composed of silicon and iron, and ferrosilicon powder is made by grinding ferrosilicon alloy into powder, so the principle of adding reducing agent in steelmaking ferrosilicon is the same as that of adding reducing agent in steelmaking ferrosilicon powder. Smelting ferrosilicon as reducing agent used in the majority is metallurgical coke, metallurgical coke in the coking process ferroalloy carbonization temperature is 1100 degrees Celsius, so high temperature metallurgical coke is also known as coke or burn, and coke is a kind of low temperature gas, is a byproduct of producing gas, each for smelting ferrosilicon smelting is not quite understand, don't understand why in the process of smelting ferrosilicon to join part of coke gas, the following will give you a comparison of the gas coke and metallurgical coke. 1. Resistance, particle size 10 ~ 15 mm various coke, specific resistance and temperature relationship.Th...
