The specific difference between 75 ferrosilicon and 72 ferrosilicon

Ferrosilicon is an essential metallurgical product for steelmaking and casting. The main models are divided into 75# and 72#.

The difference and connection between ferrosilicon and manganese silicon

Both ferrosilicon and manganese silicon are added raw materials in steelmaking. They are mainly used to remove oxygen in steel and increase the toughness and strength of steel. They are indispensable substances in steelmaking.

High-quality metallurgical additive, ferrosilicon-barium alloy

Silicon-barium alloy is an alloy product smelted by electric furnace, and its smelting materials are silica, coke, steel shavings, and barite.

The role of ferrosilicon and ferromanganese in steelmaking

Ferrosilicon and manganese-silicon are the most widely used ferroalloys in the steelmaking process. They are mainly used as deoxidizers and alloying agents in steelmaking to eliminate excess oxygen and sulfur in molten steel and improve the quality and performance of steel. In addition to being used for steelmaking, ferrosilicon is also used for smelting magnesium metal.

The role and difference between ferrosilicon and ferromanganese

Inoculants have different classification methods according to their components and uses. If they are classified according to their components, inoculants include ferrosilicon inoculants, silicon barium inoculants, rare earth inoculants, and carbon-based inoculants.

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.

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.
