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.

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.

The difference and connection between micro silicon powder and metal silicon powder

Silicon powder and metal silicon powder are two completely different products. In actual use, these two products are often confused because they are different and related. What we usually call silica fume, also known as silica fume and micro-silica fume, is the soot recovered in the process of producing metallic silicon or ferroalloy. It is widely used in rubber, paint and other industries.

Silicon-manganese alloy

Silicon-manganese alloy is an alloy composed of manganese, silicon, iron and a small amount of carbon and other elements. Silicon-manganese alloy is a composite deoxidizer commonly used in steelmaking, and it is also a reducing agent for low-carbon ferromanganese and electro-silicon thermal production of metal manganese in production.

What is silicon slag? What are the uses of silicon slag？

silicon slag is widely used in steel mills and foundries. Silicon slag can be used as a high-quality raw material for smelting and casting pig iron and silicon-manganese alloy; silicon slag can improve furnace temperature, increase the fluidity of molten iron, and high-quality slag discharge. , increase the brand; silicon slag can also be used as a deoxidizer in steel production.

Ferrosilicon 75

Ferrosilicon is a common deoxidizer. Among many deoxidizers, ferrosilicon not only has obvious deoxidizing effect, but also has a relatively low price, so it is favored by many steel smelters. Ferrosilicon 75 is a kind of ferrosilicon with a silicon content of 75%. It is also a common one in steel smelting, and the deoxidation efficiency is also improved.
