Ferromanganese: an iron alloy composed of manganese and iron.

Used as a deoxidizer and alloying agent in the steelmaking industry. In order to obtain steel with qualified chemical composition and ensure the quality of steel, deoxidation must be carried out in the later stage of steelmaking.

Silicon (called silicon in Taiwan and Hong Kong) is a chemical element. Its chemical symbol is Si, formerly known as silicon. The atomic number is 14 and the relative atomic mass is 28.09.

Ferrosilicon balls are mainly made of silicon powder, which is a special product for steelmaking to replace ferrosilicon. The purpose is to reduce production costs and resource recycling. The main specifications are: Si50 and Si65, particle size 10x50mm, and the products have been widely adopted and sold domestically And the international market.

Recarburizer is an additive used in steelmaking. It is an indispensable raw material for the production of high-quality steel. In addition, it is also a raw material for the production of electrode paste.

Used as a deoxidizer and alloying agent in the steelmaking industry. In order to obtain steel with qualified chemical composition and ensure the quality of steel, deoxidation must be carried out in the later stage of steelmaking.

Emery, also known as silicon carbide (SiC), is made by high-temperature smelting of raw materials such as quartz sand, petroleum coke (or coal coke), and wood chips (salt is needed to produce green silicon carbide) through a resistance furnace. Silicon carbide also exists in nature, a rare mineral, moissanite. Silicon carbide is also called moissanite.

The cored wire is to add various additives (deoxidizers, desulfurizers, modifiers, alloys, etc.) to be added to molten steel or molten iron into a certain particle size, and then use cold-rolled low-carbon steel strip to include it into a strip with Any length of composite material.
