The silicon in ferrosilicon balls easily reacts with water to produce hydrogen gas, which may pose an explosion risk. In addition, the product is prone to clumping when damp, which affects the uniformity of feeding.
Ferrosilicon balls need to be stored in a dry, ventilated warehouse, avoiding open-air stacking. The bottom should be isolated from ground moisture with a moisture-proof mat, and the packaging should use sealed moisture-proof bags or ton bags.
The product needs to avoid violent collisions, which may cause breakage and produce powder.
During transportation, the cargo should be secured to reduce jolting. Handle with care during transportation to avoid damage to the packaging bags.
Ferrosilicon balls of different grades have different compositions and uses, so they should be stored separately and clearly labeled to avoid mixing.
Operation and use
Silicon is a reactive element that easily reacts with oxygen and nitrogen at high temperatures.
When using it, control the timing of feeding to avoid prolonged exposure to the surface of molten steel.
If combustion occurs, do not use water to extinguish the fire. Use a dry powder fire extinguisher or cover with sand.
Ferrosilicon balls should be added to molten steel or molten iron in batches and evenly to avoid local overheating due to concentrated accumulation or segregation of components due to insufficient reaction.
Staff members should wear protective equipment such as high-temperature resistant gloves, goggles, and dust masks during operation.
Staff members should avoid direct skin contact with ferrosilicon balls during operation, and rinse with clean water immediately after contact.
