Ferro boron alloy is a common ferroalloy additive widely used in steelmaking and cast iron production. Many foundry purchasers have the same question: Is moisture protection required for storing ferro boron alloy?
The answer is definitely yes.
Ferro boron lump and ferro boron powder have certain hygroscopicity. When exposed to humid air or rainwater for a long time, the surface of ferro boron will absorb moisture. Once damp ferro boron is put into molten iron or molten steel, water vapor will instantly expand and vaporize, which easily causes splashing of high-temperature molten metal and brings potential safety hazards to on-site operators.
In addition, moisture will also affect the metallurgical performance of ferro boron alloy. Excess moisture reduces the melting rate and dispersion uniformity of ferro boron in molten metal, resulting in unstable boron absorption rate. Finally, it will affect grain refinement effect and the mechanical properties of castings and finished steel products. Long-term damp storage may also lead to surface oxidation of ferro boron, further lowering product utilization.
Recommended Storage Requirements
- Keep ferro boron alloy in dry, ventilated indoor warehouses, avoid open-air stacking.
- Use waterproof woven bags or sealed packaging for finished products.
- Keep the goods away from the ground with pallets to prevent dampness from the ground.
- Avoid mixing ferro boron with water-soluble chemical raw materials.
- Check regularly if the packaging is damaged during long-term inventory.
Moisture-proof storage is an essential requirement for ferro boron alloy. Proper storage can guarantee stable product quality and safe smelting operation.
