Introduction to Ferrosilicon Slag

Ferrosilicon slag refers to the ferrosilicon slag inoculant is formed by breaking ferrosilicon into a certain proportion of small pieces and filtering through a certain number of sieves. The block is crushed and screened according to various particle sizes.

Great use of alloy ferrosilicon

Ferrosilicon is an essential deoxidizer in the steelmaking industry. In torch steel, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used in steelmaking as an alloying agent. Adding a certain amount of silicon to the steel can significantly improve the strength, hardness and elasticity of the steel, improve the magnetic permeability of the steel, and reduce the hysteresis loss of the transformer steel.

The silicon price has reached a high level, and the carriers are willing to ship

From August 15 to August 19, the market price of metal silicon increased by more than 3000 yuan / ton this week, and low-grade brands are still in short supply.

Silicon-calcium alloys

Calcium and silicon have strong affinity with oxygen, especially calcium, which not only has a strong affinity with oxygen, but also has a strong affinity with sulfur and nitrogen, so silicon-calcium alloy is an ideal composite Glue oxygen, desulfurizer. Silicon alloy not only has strong deoxidation ability, and the deoxidized products are easy to float and discharge, but also can improve the properties of steel, and improve the plasticity, impact toughness and fluidity of steel.

Silica fume

Silicon powder is an ultra-fine siliceous powder material formed by the rapid oxidation and condensation of SiO2 and Si gas generated by metallurgical electric furnaces at high temperatures above 2000 °C and oxygen in the air.

Ferrosilicon 65

65 Ferrosilicon is mainly an iron alloy composed of iron and silicon. Since silicon and oxygen are easily combined into silicon dioxide, ferrosilicon is often used as a deoxidizer in steelmaking. The oxidation reaction itself is an exothermic reaction. Can increase the temperature of molten steel. At the same time, ferrosilicon can also be used as an alloying element additive, which is widely used in low-alloy structural steel, spring steel, bearing steel and electrical silicon steel.

72# Ferrosilicon

72# Ferrosilicon is an iron alloy composed of iron and silicon. Ferrosilicon is an iron-silicon alloy made of coke, steel scraps, quartz (or silica) as raw materials and smelted in an electric furnace. Ferrosilicon supply granularity: 0-1mm, 1-3mm, 3-10mm, 10-50mm, 50-100mm or customized.

What is the difference between 72# ferrosilicon and 75# ferrosilicon?

75# ferrosilicon is the 75A type ferrosilicon that people often say, and 72# ferrosilicon is the 75C type ferrosilicon that people often say. Generally speaking, 75# and 72# ferrosilicon are only 75% and 72% silicon content in ferrosilicon. 75 ferrosilicon is the so-called hard 75 with a silicon content of 74-80%, and 72 ferrosilicon is a soft 75 with a silicon content of 72-80%. At present, 72 ferrosilicon is commonly used in aluminum plants.

What is the use of ferrosilicon balls?

Ferrosilicon is mainly an iron alloy composed of silicon and iron. Ferrosilicon is made of coke, steel scrap and silica as raw materials, and is refined in an electric furnace to become ferrosilicon alloy. Ferrosilicon can sometimes also be used as an alloying element.

High-carbon ferrochromium

Ferrochromium is the most important raw material for the production of stainless steel, mainly used in the production of stainless steel, ball bearing steel, tool steel, nitrided steel, heat-strength steel, quenched and tempered steel, carburized steel and hydrogen-resistant steel. There is only one element that determines the properties of stainless steel, which is chromium, and each stainless steel must contain a certain amount of chromium.
