In heavy industrial operations handling molten by-products, the Qt500-7 ductile iron slag pot represents a significant advancement in high-temperature material technology. This specialized slag tank combines the superior mechanical properties of ductile iron with robust sand casting manufacturing to create durable containers for steel mills, foundries, and smelting facilities. Engineered to withstand extreme thermal cycling and mechanical stress, these slag pots provide reliable performance in the most demanding industrial environments where safety and longevity are paramount.Material Specifications and Performance Advantages
Qt500-7 ductile iron offers exceptional mechanical properties with 500 MPa minimum tensile strength, 320 MPa yield strength, and 7% minimum elongation - providing the perfect balance between strength and ductility for slag handling applications. The spherical graphite microstructure delivers superior thermal shock resistance compared to standard cast steel, reducing crack propagation under rapid temperature changes from 1200°C to ambient conditions. This material maintains structural integrity through thousands of heating and cooling cycles, with oxidation resistance up to 700°C and excellent resistance to thermal fatigue, significantly outperforming conventional carbon steel alternatives in high-temperature abrasive environments.
Advanced Sand Casting Manufacturing Process
Our manufacturing employs precision sand casting technology with resin-bonded molding systems specifically engineered for large-scale ductile iron components. The process incorporates controlled magnesium treatment and post-inoculation to ensure proper nodularization throughout the heavy-section casting. We utilize simulation-optimized gating and feeding systems to prevent shrinkage defects in critical stress areas. Each slag pot undergoes rigorous non-destructive testing including ultrasonic examination, dimensional verification, and surface quality inspection. Strategic areas prone to wear receive additional protection through specialized hardfacing applications, while lifting lugs and structural supports are integrally cast for maximum load-bearing capacity.
Comprehensive Industrial Applications
Qt500-7 ductile iron slag pots serve essential functions across multiple heavy industries. In steel production, they handle basic oxygen furnace slag, electric arc furnace slag, and ladle refining by-products. Non-ferrous metal smelters utilize these containers for copper converter slag, nickel furnace residues, and precious metal processing waste. The components are engineered with optimized volumetric capacity (typically 1-30 cubic meters) and feature reinforced lifting configurations to ensure safe handling during crane operations. The pots' design facilitates efficient slag discharge with minimal buildup, while the durable construction withstands impact loading during transportation and pouring operations.
Choose Qt500-7 ductile iron slag pots for industrial applications demanding superior thermal fatigue resistance and mechanical reliability. Our engineering expertise in high-temperature ductile iron casting delivers solutions that reduce replacement frequency, minimize maintenance costs, and enhance operational safety in severe service conditions, supported by comprehensive material certification and performance validation.
