ferro silicon for sale
First of all, we need to understand the main theoretical knowledge of ferro silicon. Ferrosilicon is a metallurgical material with rich silicon. Ferro silicon for sale is often used in casting and steel making, because it is a good deoxidizer in steel making and accelerator in casting. Ferro silicon for sale can be divided into different grades according to the silicon content. Moreover, ferro silicon 75 is always popular by lots of steel manufacturers and foundry factories. In addition, ferro silicon for sale is not only sold domestically but also exported in all over the world. Different ferro silicon grades are used for different steel making and casting.
Steel making is an ancient smelting skill. In steel making, the ferro silicon material is melted by electric furnace to form molten steel with a large amount of oxygen which will form oxides with impurities in the steel to reduce the quality of the finished steel. Therefore, it is very necessary to deoxidize molten steel. And ferro silicon is the function of deoxidation. Ferro silicon for sale is rich in silicon which can form a good deoxidizing effect with oxygen-forming silica in molten steel. Generally, silicon is required to be 0.15%-0.35% in steel making molten steel; structural steel requires 0.40%～1.75%; tool steel requires 0.30%～1.80% of silicon; and spring steel requires 0.40%～2.80%; the rust-resistant steel need to be 3.40%～4.00%.Ferro Silicon Specifications:
Casting is a new smelting technology after steel making, which is cheaper than steel making and smelting. Ferro silicon can play a good role in casting. So ferro silicon for sale can improve the distribution of graphite and promote the formation of graphite nucleation and greatly shorten the process of graphite. Ferro silicon for sale can be used as an inoculant for ductile iron in cast iron, and it can prevent the formation of carbides, promote the precipitation and spheroidization of graphite as well as improve the performance of cast iron. Huatuo metallurgy, established in 2001, is a professional ferro silicon supplier of ferro alloys and metallurgical materials with professional facilities for the production.
