Molten Metal Processing Vessels
Roben, Mfg, Inc. engineers and fabricates molten metal processing vessels for metallurgical operations requiring containment and processing of liquid metals at extreme temperatures. Our molten metal vessels feature refractory protection, cooling systems, and designs accommodating the unique challenges of handling molten aluminum, steel, copper, and specialty metals.
What Are Molten Metal Processing Vessels?
Molten metal processing vessels are high-temperature containers designed for melting, holding, treating, and transferring liquid metals at temperatures from 1200°F (aluminum) to 3000°F+ (steel). These vessels incorporate refractory linings, cooling provisions, and designs addressing the thermal shock, erosion, and chemical attack conditions of molten metal service.

Frequently Asked Questions
What temperatures do molten metal processing vessels handle?
Temperature depends on metal type: aluminum processes operate at 1250-1400°F, copper at 2000-2200°F, and steel at 2800-3100°F. We design vessels with refractory systems appropriate for specific metal temperatures and chemical characteristics.
How are molten metal vessel refractories selected?
Refractory selection considers metal type, temperature, slag chemistry, and thermal cycling. Aluminum vessels typically use alumina-silicate refractories, steel vessels use magnesia or dolomite, and copper vessels use chrome-mag or silica refractories. Multiple layers provide both containment and insulation.
What safety features are incorporated in molten metal vessels?
Safety features include shell temperature monitoring, breakout detection, emergency containment provisions, and proper personnel protection. We design for controlled metal drainage in upset conditions and incorporate features preventing water contact with molten metal, which could cause dangerous steam explosions.
