Introduction to ferrosilicon granule inoculant:
The ferrosilicon granule inoculant is formed by breaking the ferrosilicon into small pieces of a certain proportion and filtering them through a sieve with a certain mesh size. Simply put, the ferrosilicon granule inoculant is made of ferrosilicon natural blocks and standard blocks according to various Different particle sizes are broken and screened out.
Ferrosilicon granule inoculant supply particle size: 0.2-1mm, 1-3mm, 3-8mm, or customized according to customer requirements;
What is the use of ferrosilicon particle inoculant:
1. Can effectively deoxidize during steelmaking;
2. Greatly reduce the time of steelmaking deoxidation and save energy waste and manpower;
3. It has the function of promoting the precipitation and spheroidization of graphite in the production of ductile iron;
4. Can be used instead of expensive inoculants and spheroidizing agents;
5. Effectively reduce smelting costs and improve manufacturer efficiency;
Advantages of ferrosilicon granule inoculant:
Ferrosilicon granules can be used not only in the steelmaking industry but also as a commonly used metallurgical material in the cast iron industry. This is mainly because ferrosilicon granules can be used by cast iron manufacturers to replace inoculants and nodulizing agents. In the cast iron industry, the price of ferrosilicon granules is far away. Lower than steel and more easily melted, it is a ferroalloy product with superior casting capabilities. High-quality ferrosilicon particle inoculant has uniform particle size and good inoculation effect during casting. It can promote the precipitation and spheroidization of graphite and is a necessary metallurgical material for the production of ductile iron;
Things to note when adding ferrosilicon particles:
The usage amount should be determined based on actual conditions, which is closely related to the conditions of primary iron and molten iron, and should be adjusted based on actual conditions;
Generally, the amount of ferrosilicon particles added to gray cast iron is 0.2~0.5%;
For ductile iron, the general amount of ferrosilicon particles added is 0.5~1.1%;
For cast iron horizontal continuous casting of ductile iron, the general amount of ferrosilicon particles added is 0.8~1.5%.
