FAQ
Q: What temperature can 10–50 mm lumps withstand?
A: They typically withstand service temperatures from about 1 500 °C up to ~1 850 °C or higher, depending on the refractory chemistry and formulation.
Q: Can they be used in continuous industrial furnaces?
A: Yes, they can be used in continuous industrial furnaces when the material is properly specified for the system's temperature, atmosphere, and cycle conditions.
Q: Are samples available for testing?
A: Yes, manufacturers usually provide small sample quantities for evaluation and testing on request.
Q: How is the product packaged for shipment?
A: Common packaging includes 25 kg or 50 kg bags, bulk FIBCs (big bags), and palletized crates for larger orders or export.
Q: What industries benefit most from coarse granules?
A: Industries such as steelmaking, non‑ferrous metallurgy, glass furnaces, cement/lime kilns, and heat‑treatment facilities benefit most from coarse refractory granules.
Q: What is the bulk density of the lumps?
A: Bulk density varies by material; insulating grades are often ~95–160 kg/m³, while denser refractory aggregates have significantly higher densities.
Q: How long is delivery for bulk orders?
A: Typical delivery lead times are 2–6 weeks, depending on quantity, customization, and logistics.
Q: Are they suitable for both steel and aluminum furnaces?
A: Yes, but suitability depends on correct material selection for each application's temperature, chemical exposure, and wettability requirements.
Q: Can the particle size be customized?
A: Yes, particle size distributions (e.g., specific 10–30 mm or 20–50 mm fractions) can generally be customized to specification.
Q: Do they reduce furnace maintenance frequency?
A: Properly selected and installed coarse lumps can improve insulation stability and service life, which can help reduce maintenance frequency in many applications.
