4. Cast Iron Slag Pot Manufacturing Process Flow

Raw Material Selection: High-purity pig iron, alloying elements (Mn, Si, Cr), ensures melt cleanliness & design strength.
Core Making & Molding: Employs CNC-prepared sand molds. Strict dimensional control critical for slag ladle reliability.
Melting & Pouring: Induction/Electric arc furnace at 1600°C; molten metal poured into pre-heated molds; ISO/ANSI temperature logging on site.
Cooling & Shakeout: Gradual controlled cooling for uniform grain; shakeout eliminates sand residue & initial surface checks.
Heat Treatment: Normalizing and tempering cycles boost microstructure density and HB hardness (target: 200+).
CNC Machining: Load/access points, lifting lugs, and trunnions are precision-machined for interchangeability.
Inspection & NDT: Ultrasonic, dimensional, and 3D scan checks as per EN1247; third-party QC certificates provided.
Surface Treatment: Anti-corrosive paint or special coatings (for chemical industry use) per ASTM/ISO standards.
