Petroleum coke (PETroleum coke) is a product obtained by distilling crude oil through distillation to separate light and heavy oil, and then heavy oil undergoing thermal cracking. From the appearance of petroleum coke , coke is irregularly shaped, black lumps (or particles) of various sizes, metallic luster, and coke particles have a porous structure. The main elemental composition is carbon, which accounts for 80wt% The English abbreviation of Weight means the weight percentage content. 5WT% is equivalent to more than 50,000 PPM (PPM is in millions of content), and the rest are hydrogen, oxygen, nitrogen, sulfur and metal elements. http://www.ferroeast.com/know/petroleum-coke.html Petroleum coke has its unique physical, chemical and mechanical properties. It is a non-volatile carbon that generates heat, and volatiles and mineral impurities (sulfur, metal compounds, water, ash, etc.) determine the chemical properties of coke. Petroleum coke can be used in graphite, sm...

1.Silicon slag(off grade silicon) is a by-product when making silicon metal. 2.The silicon content is from 45% to 95%, and the rest are C, S, P, Al, SiO2, Fe, Ca etc. 3.The silicon slag is much cheaper than purity silicon metal, and has many industrial Application 1.Silicon Dross(offgrade silicon metal) is a good substitute for ferro silicon in steel making which has advantage in reducing the making cost. 2.The silicon slag powder can be made silicon briquette which has far and wide market at home and abroad. 3.Silicon Dross(offgrade silicon metal) is used as deoxidizer in steel making.

Many types of additives are added to the smelting of steel. For different additives, the effects they play are different. Calcium silicon cored wire is a common additive in our lives. Other additives are different. Only in the correct way of adding ferroalloy can the function of silicon calcium wire be better played. So how to use silicon calcium wire correctly? Let's follow the manufacturers of silicon calcium wire to find out. Solid core pure calcium wire reacts with molten steel more fiercely than silicon calcium wire during calcium treatment. Caution should be paid to the calcium treatment operations, such as feeding depth and wire feeding speed. Due to the high vapor pressure of the solid core pure calcium wire, In order to prevent the natural evaporation of calcium, solid pure calcium wire must be fed deep. One method is to increase the thickness of the iron sheet to prevent its premature melting from affecting the depth of calcium release. The other method is to incr...

Silicon slag now in metallurgical materials is to occupy a more important position, because the price affordable can also be more practical, steelmaking and casting favored, the following si slag manufacturer henan star metallurgy will give you a detailed explanation of the use of si slag, there are a lot of applications absolutely let you expect, then read down; What is silicon slag? Silicon slag is the production of ferrosilicon, and other alloy material after the rest of the parts, but also contain a proportion of silicon slag metal silicon, silicon slag alloy in the industry according to the purposes can be roughly divided into industrial silicon, semiconductor silicon slag slag alloy, solar silicon slag alloy slag, silicon metal, alloy, etc., silicon alloy or other silicon slag production ball of a raw material; Henan star metallurgy factory supplies blast furnace pig iron, bread iron, castings special silicon slag Silicon slag: Si content :30%, 40%, 45%, ...

Casi cored wire is widely used in steelmaking, casting, deoxidation and other industries with good use value, as a new metallurgical material, Calcium silicon cored wire has incomparable advantages over other metallurgical materials, because si-ca cored wire is a new metallurgical material.Star metallurgy, a professional manufacturer of silicon and calcium cored wire, introduces the production process and application of silicon and calcium cored wire. You will better understand this advantageous product. Production process of silicon calcium cored wire Calcium silicon packet core main raw material is calcium silicon powder, the calcium silicon powder ACTS as the core material, the skin is steel sheet, through professional repression and line pressing machine, in the process of making calcium silicon packet core must pay attention to whether the steel bag, with and without leakage material, core material is filled evenly, more attention should be strictly check the rin...

Henan star metallurgy specializes in ferrosilicon alloy , 75 ferrosilicon, 72 ferrosilicon research and sales, ferrosilicon price how much money a ton?The company will offer the price according to the content and granularity required by customers at any time. Introduction to ferrosilicon products: Ferrosilicon is an alloy of iron and silicon.Ferrosilicon is an iron and silicon alloy made from coke, steel chips, quartz (or silica) and smelted in an electric furnace. Cost composition of ferrosilicon: production cost = silica + steel chips + blue carbon + electricity + labor + packaging. Several factors influencing the price of ferrosilicon : 1. Electricity price factor: the standard power consumption of producing 1 ton of ferrosilicon is about 9000 degrees, and 90% of the cost of ferrosilicon is also electricity price. For every one minute increase in electricity price, the cost of ferrosilicon will rise by about 100 yuan per ton. 2, the price of raw materials, coke,...
