Ferric Silicon Inoculant

Description

Ferric Silicon Inoculant is a ferroalloy made of coke, steel scrap, and quartz, and smelted in an electric furnace. It is mainly composed of silicon and iron. Silicon and oxygen are easy to synthesize silica, so ferrosilicon is often used as a deoxidizer in steelmaking. At the same time, a large amount of heat is released during the formation of SiO2, which can increase the temperature of molten steel and reduce energy consumption while deoxidizing. Ferrosilicon can also be used as an alloying element additive, widely used in low alloy structural steel, spring steel, bearing steel, heat resistant steel, and electrical silicon steel. Ferrosilicon is often used as a reducing agent in iron alloy production and the chemical industry.

The ferrosilicon inoculant is formed by crushing the ferrosilicon into a certain proportion of small pieces and filtering through a certain mesh of sieve to form the ferrosilicon inoculant. Simply put, the ferrosilicon inoculant is composed of natural ferrosilicon blocks and standard blocks according to various Different granularities are crushed and screened out of small granules.

Application

1. Ferric Silicon Inoculant can effectively deoxidize during steelmaking;

2. Greatly reduce the time of steelmaking deoxidation, saving energy waste and manpower;

3. It has the effect of promoting the precipitation and spheroidization of graphite in the production of nodular cast iron;

4. It can be used instead of expensive inoculants and nodulizers;

5. Effectively reduce the cost of smelting and improve the efficiency of manufacturers;

Advantages

Ferrosilicon granule can be used not only in the steelmaking industry but also metallurgical materials commonly used in the cast iron industry. This is mainly because ferrosilicon pellets can be used by cast iron manufacturers to replace inoculants and nodulizers. The price of ferrosilicon pellets in the cast iron industry is far Lower than steel, and easier to be melted.

Features

Ferric Silicon Inoculant is an additive used in the casting process, which can promote graphitization, reduce chilling tendency, improve graphite morphology and distribution, increase the number of eutectic clusters, and refine the matrix structure. Within a short period of time (approximately 5-8 minutes) after vaccination, good results are achieved.

For gray iron castings, the main function of inoculation treatment is to promote graphitization, reduce the tendency for white spots, increase the number of eutectic groups, and promote the formation of A-type graphite and fine pearlite. For ductile iron, the main function of inoculation treatment is to promote graphite precipitation, improve the inhibition effect on eutectic penetration, and increase the number of graphite spheres per unit area. The results indicate that the microstructure of ductile iron is more uniform, which improves the plasticity and toughness of ductile iron.
