What are the application areas of ferrosilicon?

图片
Henan star metallurgy is a professional production of  ferroalloys  and m etallurgical materials manufacturers , the following to introduce to you several major uses of ferro silicon . (1)  ferro silicon  is used as an oxygen attribution and alloy in the steelmaking industry. In order to obtain the chemical composition of qualified steel and ensure the quality of steel, in the final stage of steelmaking must be deoxygenated, silicon and oxygen between the chemical affinity is very large, so ferro silicon is a strong deoxygenator for precipitation and diffusion deoxygenation. Adding a certain amount of silicon to the steel can significantly improve the strength, hardness and elasticity of the steel, so when smelting structural steel (including silicon 0.40-1.75%), tool steel (including SiO.30-1.8%), spring steel (including SiO.40-2.8%) and silicon steel (including silicon 2.81-4.8%) in smelting structures,  ferro silicon  is also used as an alloy agent....

Why is silicon slag so popular?

Silicon slag  is a by-product in the process of producing metallurgical materials such as metal silicon, and silicon slag can be divided into industrial silicon slag, silicon slag ball, solar silica slag, metal silicon slag, semiconductor silicon slag and so on. Silicon slag 60   manufacturers factory price cheap containing silicon content of 60%, the main use is used as steel-making manufacturers in the process of deoxygenating agents to use. Silicon slag 60 compared to ordinary ferroalloy products have a congenital advantage, it factory price is low deoxygenation effect is very good, can be effectively replaced by manufacturers silicon iron, metal silicon and other relatively expensive products, the use of silicon slag 60 can effectively reduce production costs of manufacturers to reduce the production time to improve steelmaking efficiency, The use of silicon slag 60 when making steel can increase the furnace temperature and increase the recovery rate of steelmaking....

What is the role of carburizer in steelmaking?

As we all know, carbon adders play an important role in steelmaking, that small editor today to lead you to see what is the use of carbon boosters?  Use of carbon adders:  First, the main procurement object of the carbon booster or mainly to steel-making manufacturers, its main purpose is to increase the loss of carbon elements in the steelmaking process, in the steelmaking process, if the carbon content does not meet the expected requirements, it is necessary to put a certain proportion of carbon-adders, its main cloud map is to enhance the carbon content in steel water, so as to smelt the ideal steel. Second, carburizer are widely used, can also be used in the casting industry, in casting carburizer have the use of reducing gradual costs, carburizer as casting materials can greatly reduce the gradual cost, and carburizer with lubrication purposes, can effectively improve the service life of castings, improve the gradual quality; Third, different kinds of cast iron, a...

The reason for the rising price of ferrosilicon

1.  ferrosilicon  raw material silica shortage Environmental inspection team on the northwest region of silicon mining strict control, raw materials silica is now in short supply. 2.  ferro silicon  spot less ferro Silicon manufacturers into the steel plant tender back single production state, less spot, and a large ferro silicon production enterprises due to equipment upgrade all discontinued, affecting the output of more than 20,000 tons. Caused the recent sharp rise in  ferro silicon  (about 600 yuan / ton), and even alloy manufacturers suspended the offer. 3, futures pull up ferro silicon futures 1909 contract opened significantly higher, the amplitude of the disk expanded, and finally closed a negative line with a longer shadow line. From a technical point of view: short-term overbought, the formation of a new rising channel, 6300 line into a long-short competition for key points, the validity and continuity of fundamental news on the face h...

petcoke and graphite carbon-adders after radon?

Many manufacturers in the procurement will be a bit vague carbon booster types, so today we look at the difference between  petcoke  adders and graphite carbon adders. First Raw materials: are made of raw  petcoke . Second: fixed carbon content (1) Graphite carbon adder fixed carbon is generally about 98%, up to 99%. (2) After the calcium  petcoke  carbon-adder fixed carbon is generally about 98.5%. Third: smelting environment (1) Graphite carbon adders are produced at a temperature of about 3000 degrees C in a graphite smelter. (2) After-the-day  petcoke  adder is produced at a temperature of more than 1500 degrees C after forging furnace. Fourth: Smelting time: Graphite carbon-adder smelting environment than after the otar carbon-adder smelting time is long. Fifth: Sulfur content (1) The sulfur content of graphite carbon booster is generally between 0.03-0.06%, generally 0.05% more. Absorption rates are generally between 90% a...

Why is calcium siliocon alloy used as deoxidizer for steel making

图片
Silicon calcium alloy is an essential deoxidizer for steel mills, this question should be clear to the industry, so why is s iliconcalcium alloy often used as a deoxygenator for steelmaking? http://www.pupanferroalloys.com/products/calcium-silicon/ Today to lead you together to see what the reason is Silicon calcium alloy is a composite alloy material, mainly composed of silicon, calcium, iron and other trace elements. In the steelmaking industry, silicon calcium alloy is mainly used as a compound deoxygenator, desulfurization agent. However, in addition to silicon calcium alloy, there are other kinds of steel-making deoxygenators on the market, the competition is very fierce, but silicon calcium alloy in such a context, and not greatly affected, still by virtue of its own strength, won the recognition of many users. Compared with other steel-making deoxygenators, calcium in silicon calcium alloy , silicon and oxygen have a strong affinity, and with sulfur, nitrogen also ...

What is a silicon carbon alloy??

electrolytic manganese metal flake supplier

Production process for  electrolytic manganese metal flake  At present, China's  electrolytic manganes e chip production mainly to 99.7% of the products (now most manufacturers have actually reached more than 99.8%), only a few manufacturers produce 99.9% of the products (because 99.9% of the product market demand is small. However, many enterprises in the feasibility study report are called the production of 99.9%, the main raw materials - manganese ore for manganese oxide ore and manganese carbonate ore two categories, in addition to the previous process of liquid production methods are not the same,  electrolytic manganese  chip production process is basically the same. Manganese carbonate ore is directly using sulfuric acid and manganese carbonate combined reaction to obtain manganese sulfate solution, and then through the middle, purification, filtration and a series of processes prepared for electrolyte, by adding additives such as selenium di...
