Application of silicon in cast iron

The effect of silicon in cast iron is multifaceted. In addition to "promoting graphitization" and "solid solution strengthening", silicon has many important effects.

What role does silicon calcium cored wire play in the steelmaking process?

Silicon calcium cored wire is a common silicon calcium cored wire in steel smelting. The application of this cored wire can avoid adding other impurities during feeding. At the same time, the silicon calcium content in this silicon calcium wire is more. , which can react with oxygen and other harmful elements in molten steel during use, thereby removing them.

Introduction of silicon calcium manganese deoxidizer

Silicon calcium manganese deoxidizer is a new type of composite deoxidizer, which is widely used in various steelmaking and ironmaking deoxidation. Silicon calcium manganese can effectively improve the properties of steel and improve the plasticity, impact and fluidity of steel.

Silicon Metal Grades Instruction

Silicon metal is rich in silicon and is widely used in steel making, casting foundry, aluminium ingot production, purification and other industries. The content of different silicon metal grades varies and their applications are very different. The main common grades of silicon metal grades of silicon metal grades of silicon metal grades of silicon metal are 441, 553, 3303 and 2202, but in addition to these grades there are some lesser known grades, such as 421, 411 and 1101.

Application of silicon metal in aluminum alloy die casting process

silicon metal is usually added in the aluminum ingot casting process. Why do you want to add it? The following metal silicon manufacturers will share with you the effect of adding silicon metal in the aluminum casting process. I hope it will be helpful to you;

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.
