Steel Casting Salt Slag Bins — Cast Steel Containers for Secondary Aluminium Remelt Operations

SMI steel casting salt slag bins are purpose-built cast steel containers designed for the collection, cooling and transport of hot salt slag generated by secondary remelt tilt rotary furnace operations. The bins are engineered to withstand the extreme heat and corrosive conditions of salt slag handling in secondary aluminium smelters and recycling plants — conditions that standard fabricated steel containers cannot reliably manage over an extended service life.

Salt slag bins supplied by SMI are compatible with dross press systems for integrated dross processing workflows, and can equally be deployed as standalone salt slag cooling vessels where a separate cooling process is preferred. Custom dimensions and configurations are available to suit specific furnace output volumes, material handling equipment and floor space constraints.

Design and Construction

Cast Steel Construction

SMI salt slag bins are manufactured as cast steel components — not fabricated from plate. Cast construction provides uniform wall thickness, eliminates weld seams as potential failure points, and delivers the structural mass necessary for effective thermal absorption during hot salt slag containment. The cast steel body is engineered for repeated thermal cycling from ambient temperature to the temperature of freshly discharged rotary furnace salt slag without cracking or distortion.

Internal Profile

The internal profile of the bin is designed for clean discharge of cooled salt slag without material sticking to the walls or base. Draft angles and internal surface geometry are specified to minimise manual intervention during discharge and to reduce wear on the internal surface over repeated use cycles.

Base and Support Structure

The base and support feet are cast integrally with the bin body — no secondary fabrication or welded attachments. The base structure provides stable, level positioning on casthouse floor surfaces and accommodates standard forklift handling for transfer between furnace, cooling area and downstream processing.

Optional Lid Configuration

A lid configuration is available as an optional addition for applications where containment of airborne salt slag particulate during transport is required. Lid options are confirmed at the enquiry stage based on the specific handling and environmental requirements of each installation.

Application

SMI steel casting salt slag bins are designed for use in the following operational contexts:

• Secondary remelt tilt rotary furnace operations — primary application, direct collection of hot salt slag at furnace discharge
• Integrated dross press workflows — compatible with SMI dross press systems and third-party press installations for combined dross and salt slag processing
• Standalone salt slag cooling — independent cooling process where salt slag is held in the bin for the full cooling cycle before transfer to downstream processing
• Hot slag collection and transport — general casthouse slag handling in primary and secondary aluminium smelters, aluminium recycling plants and non-ferrous metal processing facilities

En Español — Contenedores de Escoria Salina para Operaciones de Refusión Secundaria de Aluminio

Los contenedores de escoria salina de fundición de acero de SMI son recipientes de acero fundido diseñados específicamente para la recolección, enfriamiento y transporte de escoria salina caliente generada por operaciones de hornos rotativos inclinables de refusión secundaria. Están diseñados para soportar el calor extremo y las condiciones corrosivas del manejo de escoria salina en fundiciones secundarias de aluminio y plantas de reciclaje.

Los contenedores son compatibles con sistemas de prensa de escoria para flujos de trabajo integrados de procesamiento de escoria, y también pueden utilizarse como recipientes independientes de enfriamiento de escoria salina. Se encuentran disponibles dimensiones y configuraciones personalizadas para adaptarse a los volúmenes de producción específicos de cada instalación, equipos de manejo de materiales y restricciones de espacio.

SMI ofrece servicio de entrega DDP, con un plazo de entrega de aproximadamente 22 semanas desde la confirmación del pedido. El servicio de instalación en sitio está disponible con cargo por día. Para consultas técnicas o solicitudes de cotización, por favor contacte al equipo de SMI →
