Let's learn about silicon-calcium alloy
A binary alloy composed of silicon and calcium belongs to the category of ferroalloys. Its main components are silicon and calcium, and it also contains impurities such as iron, aluminum, carbon, sulfur and phosphorus in varying amounts. In the iron and steel industry, it is used as a calcium additive, deoxidizer, desulfurizer and denaturant for non-metallic inclusions.

Matters needing attention in the selection of micro-silica fume impact-resistant and wear-resistant concrete
Concrete protection surface should be easy to make the surface to meet the flatness required by the design, which requires that the selected concrete has good workability;

What is steelmaking deoxidizer
In order to ensure smooth casting and rolling into qualified steel, a certain amount of deoxidizer is added to the molten steel for deoxidation at the end of smelting or during tapping, and at the same time, an appropriate amount of alloy is added to adjust the chemical composition according to the requirements of the steel specification.

Why does steelmaking need deoxidation
In order to ensure smooth casting and rolling into qualified steel, a certain amount of deoxidizer is added to the molten steel for deoxidation at the end of smelting or during tapping, and an appropriate amount of alloy is added to adjust the chemical composition according to the requirements of the steel specification. Generally, there are silicon-manganese alloys, ferrosilicon, ferromanganese, ferro-aluminum, silicon-aluminum-barium-calcium, etc.

10 important functions of silica fume in concrete
Silica fume can fill the pores between cement particles, and at the same time form a gel with the hydration product, and react with the alkaline material magnesium oxide to form a gel. Adding an appropriate amount of silica fume to cement-based concrete, mortar and refractory castables can play the following roles:
-
The difference between white silica fume and gray silica fume
White silica fume and gray silica fume are two kinds of silica fume materials with different colors, and their main difference lies in the color. In addition, there are some differences in application and properties, which are detailed below:
-
The difference between metal manganese and electrolytic manganese
The metal manganese obtained by electrolysis after treating manganese powder with chemical raw materials such as sulfuric acid is called "electrolytic manganese", which is a chemical process. Manganese carbonate and other manganese compounds in manganese ore become metal manganese.

Ferrosilicon alloys and silicon metal have different uses
In summary, ferrosilicon alloys are mainly used in the steel industry, while silicon metal is used in the production of electronics, solar energy, and alloys.

Manufacturing process of ferrosilicon
Silicon iron is an alloy made from silicon and iron, which is widely used in the steel industry for its properties such as high silicon content, good resistance to oxidation and corrosion, and high temperature stability. The manufacturing process of silicon iron involves several steps, as outlined below:

Difference between ferromanganese and silicomanganese
Ferromanganese and silicon manganese are both added raw materials in steelmaking, mainly used to remove oxygen from steel and increase the toughness and strength of steel. They are indispensable substances in steelmaking.
