9. Expertise FAQ: Cast Iron Slag Pot & Slag Tank

Frequently Asked Questions

1. What materials are used for high-performance cast iron slag pot production?

Most leading models use high-chromium ductile iron (≥16% Cr) or specialized Ni-Hard alloys, achieving superior heat and corrosion resistance. Lower-end models use grey or standard cast iron.

2. What standard certifications should a qualified slag pot meet?

Look for ISO 3755 “Cast iron – Quality requirements”, ANSI B16.9 for shape/connection, and optionally, EN 1561 for mechanical properties. Compliance ensures repeatable quality.

3. How does the geometry (e.g., trunnion/handle) affect performance?

Bespoke handle geometries improve mechanical stress distribution, simplify overhead crane operations, and decrease failure rates around welds or corners.

4. What is the typical delivery/lead time for a custom slag tank order?

Standard cycle is 30–45 days including design, mold-making, casting, testing, and delivery. Emergency delivery with expedited mold can reach 21 days.

5. How is service life validated? Are there field test results?

Field results are validated via cycle count (operation logs), with non-destructive testing (ultrasound, dye-penetrant, X-ray) documented. ZY Mining’s Slag Tank routinely exceeds 5,000 service cycles; test reports available upon request.

6. Can the slag tank resist chloride/sulfur corrosion in harsh environments?

Yes, high-alloy irons and advanced anti-corrosion coatings (e.g., epoxy/polyurethane, enamel) ensure minimal corrosion even in severe chemical settings.
