DYNAMO FURNACES — SAGUENAY–LAC-SAINT-JEAN

Aluminum Recycling & Remelting Equipment for Saguenay–Lac-Saint-Jean

Aluminum scrap, chip, dross and remelting furnace systems for processors, recyclers, foundries and manufacturers throughout Saguenay–Lac-Saint-Jean, Québec.

Keep more aluminum inside the production cycle

Saguenay–Lac-Saint-Jean is closely connected to aluminum production, transformation, research and equipment manufacturing. As metal moves downstream into casting, extrusion, fabrication and machining, plants generate valuable secondary streams: foundry returns, rejected castings, profiles, offcuts, machining chips, process scrap and dross.

Dynamo Furnaces supports the stage after primary aluminum production. Its equipment is designed for preparing, remelting and recovering secondary aluminum—not for electrolytic smelting cells.

Start with the material stream

Furnace selection begins with the aluminum entering the process. Alloy, geometry, surface area, moisture, coolant, coatings, oxidation and contamination all affect preparation, melting behaviour, recovery yield and downstream metal quality.

Machining chips & swarf

Light, high-surface-area material that may carry coolant, cutting oil or moisture and can oxidize rapidly.

Foundry & production returns

Gates, risers, rejected castings, extrusion offcuts and segregated internal scrap.

Mixed prepared scrap

Variable shapes, densities, coatings and contamination requiring a suitable recovery process.

Dross & oxide-rich material

A distinct stream containing aluminum oxide and recoverable metallic aluminum.

Recovered molten aluminum

Metal that can return directly to production, move into holding or be cast into ingot.

Prepare chips before controlled melting

Machining chips may need segregation, washing and drying before they enter a furnace. A predictable preparation sequence can improve feeding consistency and help control moisture, contamination, oxidation and dross generation.

1. Collect & segregate

Keep alloys separate and document chip production by shift, day or week.

2. Wash

The CWS-A aluminum chip washing system removes residual machining fluids and contaminants.

3. Dry & meter

Dry prepared chips and deliver them to the furnace at a controlled rate.

4. Melt & recover

Match the melting equipment to chip condition, alloy, required capacity and final metal use.

Furnace paths for secondary aluminum

GM-M chip melting

Dedicated melting for prepared aluminum chips, swarf and turnings from machining operations.

GM-G chip & scrap melting

A recovery path for prepared chips combined with compatible bulk production scrap.

GM-D dry hearth melting

Controlled heating of selected production scrap and returns before metal enters the main bath.

GDR-C rotary scrap recovery

A rotating thermal process for variable, mixed, coated or oxide-rich prepared aluminum scrap.

GDR-B dross recovery

Equipment designed to recover usable metallic aluminum from dross and organize the residue stream.

Holding & ingot casting

Maintain recovered liquid metal for production or convert it into a storable, transportable solid form.

When a plant produces chips and solid scrap

Many regional manufacturers generate several compatible aluminum streams at once: machining chips, extrusion offcuts, rejected components, gates, risers and other foundry returns. The project should assess the full daily mix instead of designing around one ideal sample.

The GM-G chip and scrap melting path can be evaluated where prepared machining material and compatible bulk scrap need to enter one coordinated recovery process. The system must still be sized around alloy segregation, feed condition, generation rate, desired throughput and the required recovered-metal format.

Mixed scrap and dross require different recovery strategies

GDR-C rotary scrap recycling

Mixed or difficult scrap may contain variable geometry, surface coatings, oxidation and differing densities. The GDR-C rotating drum keeps the charge moving through the thermal process to support heat transfer and recovery of metallic aluminum from suitable prepared material.

GDR-B dross recovery

Dross is not ordinary production scrap. A dross project begins with generation rate, metallic content, alloy, current handling, storage, residue management and the intended form of recovered metal.

Plan the complete aluminum recovery line

The furnace should be selected as part of the complete material flow. A closed-loop system may connect collection, alloy segregation, size reduction, washing, drying, controlled melting, holding and ingot casting.

Collect

Capture returns and machining waste at the source.

Sort

Separate alloys and incompatible materials.

Prepare

Wash, dry, reduce size and meter the feed.

Recover

Select furnace technology around the actual stream.

Hold or cast

Return liquid metal to production or create ingot for storage and sale.

Measure usable metal—not furnace capacity alone

Two furnaces can process the same nominal weight per hour yet produce different quantities of usable aluminum. A sound recycling study measures incoming scrap, recovered metallic aluminum, dross or residue, energy, labour and final usable metal.

Feed preparation also affects the result. Wet chips and dry prepared chips behave differently; so do large irregular pieces and consistently sized scrap. For Saguenay–Lac-Saint-Jean operations, preparation and melting should be evaluated together.

Recovery yield

How much usable metal is produced from each tonne entering the process?

Feed consistency

How stable are alloy, geometry, moisture, coolant and contamination?

Final destination

Will recovered metal return as liquid to production or be cast into ingot?

Serving the Saguenay–Lac-Saint-Jean aluminum economy

Alma, Saguenay and Jonquière sit within a mature aluminum ecosystem that includes primary production, downstream transformation, research, technology, fabrication, machining and specialized industrial services. Dynamo’s opportunity begins as aluminum moves downstream and production creates recoverable secondary material.

Alma & Lac-Saint-Jean

Support for downstream manufacturers, processors and operations generating machining chips, casting returns and production scrap.

Saguenay & Jonquière

Applications for internal scrap recovery, foundry return remelting, dross recovery and closed-loop aluminum systems.

Regional processors

Equipment paths for secondary aluminum recyclers, foundries, machine shops and component manufacturers.

Match the equipment path to the material

Dynamo equipment for secondary aluminum processing

Dynamo Furnaces supplies equipment for chip preparation, controlled melting, scrap and dross recovery, molten-metal holding and ingot casting. The system is configured around the plant’s real aluminum stream and the metal required downstream.

Processing aluminum in Saguenay–Lac-Saint-Jean?

Tell us what material you generate, its alloy, quantity, condition and current destination. Explain whether recovered metal should return to production as liquid or leave the process as ingot. Dynamo can then evaluate preparation, furnace technology, downstream handling and the overall recovery configuration.
