Safety & Handling Instructions

Wear protective equipment (high-temperature gloves, masks, goggles) during operation, especially in casting high-temperature scenarios, to avoid burns and powder inhalation.
Store in a cool, dry, ventilated and fire-proof place, away from open flames, high temperatures and oxidants, to prevent oxidation and agglomeration.
Avoid mixing with strong acids, strong bases and flammable materials to prevent chemical reactions and potential safety hazards.
After casting use, properly treat the residual powder and reaction residues to avoid environmental pollution.
Refer to the MSDS for detailed safety information before use, and strictly follow the industrial operation specifications.

FAQ (Chemical-grade & Casting Use)

Q1: What is the role of this pyrite powder in casting? A1: It mainly acts as a deoxidizer and desulfurizer—during casting, it reacts with oxygen and sulfur in molten metal to form stable compounds, which are removed with slag, reducing casting defects and improving the mechanical properties of castings.
Q2: Why is it called chemical-grade pyrite casting powder? A2: It adopts chemical-grade purification technology, with high purity and low impurity content, which not only meets the strict requirements of chemical industry for raw materials, but also adapts to the high-standard needs of casting industry for auxiliary materials, realizing dual-scene application.
Q3: What is the recommended dosage in casting? A3: The dosage depends on the type of casting metal and impurity content. For general steel casting, the recommended dosage is 0.3%-0.8% of the molten metal weight; it is recommended to test and determine the optimal dosage before large-scale use.
Q4: Can it be used in high-temperature casting scenarios? A4: Yes. It has excellent high-temperature resistance, can adapt to the high temperature of molten metal (1500-1800℃) in casting, and its deoxidation and desulfurization performance remains stable without decomposition or failure.
Q5: Is there any difference between this product and ordinary casting pyrite powder? A5: Yes. This product is chemical-grade, with higher purity and lower impurity content, which can avoid the impact of impurities on casting quality and chemical reactions; its particle size is more uniform, ensuring more stable performance than ordinary products.
Q6: Can it be used for all types of casting processes? A6: It is suitable for most casting processes, including sand casting, die casting, investment casting, etc., and is compatible with various casting metals (steel, iron, non-ferrous metals), with strong adaptability.
Q7: How to store the product to avoid performance loss? A7: Store in a sealed, moisture-proof and fire-proof container, place in a cool and ventilated place, avoid direct sunlight and high temperature, and prevent moisture absorption, agglomeration and oxidation, which can be stored for 12 months.
Q8: Do you provide after-sales technical guidance for casting use? A8: Yes. We have a professional technical team that can provide targeted dosage guidance, use methods and problem solutions according to your casting process and needs, ensuring the best use effect.
