Introduction and use of ferrochrome
High-carbon ferrochrome (4-8% carbon), medium-carbon ferrochrome (0.5-4% carbon), low-carbon ferrochrome (0.15-0.5% carbon), micro-carbon ferrochrome (0.06% carbon %), ultra-fine carbon ferrochromium (carbon content less than 0.03%), metal chromium, silicon chromium alloy ferrochromium: a ferroalloy composed of chromium and iron, is an important alloy additive for steelmaking.

Introduction to ferrosilicon particles
The ferrosilicon particle inoculant is formed by crushing ferrosilicon into small pieces of a certain proportion and filtering through a certain number of sieves. The small particles that are crushed and screened out with different particle sizes.

Silicon aluminum barium calcium is a common compound deoxidizer in steel smelting.
Compared with other deoxidizers such as ferrosilicon, silicon aluminum barium calcium has more deoxidizing elements, and under the comprehensive action of various elements, for The quality of the steel also helps a lot. The deoxidizing element in silicon aluminum barium calcium is not only silicon, aluminum, barium, calcium, etc. can also be combined with oxygen to remove oxygen. In order to deepen everyone's understanding of this product, let's analyze the role of different elements in detail.

Introduction of metal silicon grades
Silicon metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. Silicon metal is a product smelted from quartz and coke in an electric furnace. The main component silicon content is about 98%, and the remaining impurities are iron, aluminum, calcium, etc.

How to classify ferroalloys
In a broad sense, ferroalloys refer to adding deoxidizers, element additives, etc. to molten iron during steelmaking to make steel have certain properties or achieve certain properties. A product for a requirement. An intermediate alloy composed of iron and one or more elements, mainly used in iron and steel smelting.

The difference between silicon metal and ferrosilicon
The biggest difference is that industrial silicon is silicon metal and ferrosilicon is an alloy product. Both are substances containing silicon. The difference is: industrial silicon is a simple substance in pure substances, which is obtained through industrial smelting. Ferrosilicon is an alloy, which melts silicon and iron elements together at a high temperature in a certain proportion to form a product that meets people's specific needs.

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.

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.
