The size of ferroalloy generally refers to its average particle size, which has a great influence on the use effect of ferroalloy. Generally speaking, the smaller the particle size, the slower the melting speed of the iron alloy and the better the use effect. During production, the size of the alloy needs to be determined according to customer needs.
Ferroalloy size refers to the size and distribution of ferroalloy particles. According to the application requirements of ferroalloys, different ferroalloy particle size standards are also different.
Generally speaking, the particle size standards of ferroalloys are classified in the following ways:
1. Classification according to particle size distribution range: Ferrous alloy particle size standards include coarse particles, medium particles, fine particles, etc.
2. Classification according to particle size distribution: Ferrous alloy particle size standards include lump, powder, granular, etc.
Generally, the particle size of ferroalloy is 10~50mm. During the steelmaking process, the components of molten steel and ferroalloy can be evenly fused to cause chemical reactions and reduce losses. Ferroalloy must be baked before use, mainly to reduce gas entrainment. into molten steel.
The importance of granularity
1. Permeability of molten iron
The size and distribution of particles affect the permeability of molten iron. Uneven particle size will cause uneven penetration of molten iron, causing problems such as clogging of the molten iron port, affecting production efficiency and quality of molten iron.
2. Smelting effect
The size of the particles will affect the smelting effect. Particles that are too large or too small will affect the reaction rate and degree of reaction, thereby affecting product quality and production efficiency.
3. Storage and transportation
Particle size and distribution also affect storage and transportation. Particles that are too large or too small increase the risk of aggregation and particle separation during storage and transportation.
