What is the specific difference between 75 ferrosilicon and 72 ferrosilicon
Ferrosilicon is a necessary metallurgical product for steelmaking and casting. The main models are divided into ferrosilicon 75 and ferrosilicon 72. What is the difference between them?

what is the price of metal silicon 553?
The production of metal silicon is a high-energy-consuming industry, and the production of single-ton metal silicon requires 12,000 kWh. Silica is the basic raw material for raw materials, and petroleum silicon, charcoal and low ash bituminous coal are used as reducing agents to produce metal silicon. Metal silicon products include both silicon and silicon powder. Among them, silicon metal 553 is the most widely used one.

What is the use of ferrosilicon in the steelmaking industry?
Ferrosilicon is used as a deoxidizer and alloying agent in the steelmaking industry. Ferrosilicon is used as an inoculant and spheroidizing agent in the foundry industry. Steelmaking and casting are basic heavy industries, so it is very useful to understand the raw material additives used in the heavy industry. necessary.The following ferroalloy manufacturers will share with you what is ferrosilicon and what is the purpose of ferrosilicon?

Selection of spheroidizing agent and inoculating agent?
1. Selection of spheroidizing agent: (1) 4%, 5% and 5.5% magnesium content belong to low magnesium spheroidizing agent, RE between 1% and 2%, mostly used for intermediate frequency furnace smelting, low sulfur liquid spheroidizing treatment. It has the advantages of mild spheroidization reaction and easy absorption of spheroidized elements.

Cupola silicon slag
Cupola silicon slag: cupola smelting technology is mainly used for casting molten iron at present. This technology uses pig iron as raw material, coke as fuel, limestone slag, air for combustion, and finally molten iron is smelted.

Method of use of carburizer
In the process of smelting steel, because of the improper operation of the ingredients or charging will cause decarbonization too, sometimes it will cause the content of carbon in steel does not meet the requirements, at this time it is necessary to increase the carbon in the liquid steel, so the commonly used carburizer has pig iron and petroleum coke powder and charcoal powder and other raw materials.

Graphite column carburizer
Graphitized column carburizer is an upgraded version of graphitized carburizer, which is relatively cheap, good quality and widely used.
-
Casting carburizer use requirements
Casting carburizer is a kind of additive used in steelmaking, which can greatly increase the amount of scrap steel and reduce the amount of pig iron or no pig iron.The use of carburizer in steelmaking can not only reduce the use of pig iron, but also

Use characteristics of slag remover
Slag remover is used to remove impurities in molten iron and steel in casting.The specifications of the slag agent are mainly 18-30 mesh, 30-50 mesh, 50-80 mesh.Slag removal agent selection of high quality pearlite sand processing.So what are the

Industrial use of ferrosilicon powder
Ferrosilicon powder is an alloy of silicon and iron that is then ground into a powdery substance and used as a deoxidizer in steelmaking and iron making.Ferrosilicon powder is widely used in steelmaking and cast iron industry, so ferrosilicon powder is
