High temperature car bottom furnaces are commonly used for metal heat treating in air or protective atmospheres and many other processes. They are manufactured in a wide variety of sizes and temperature ranges and exclusively designed for intensive use. They assure temperature uniformity repeatability of not less than ±8°C (±14°F) according to AMS2750F, Class 3 furnaces.
High Temperature Car Bottom Furnaces are heavy-duty, rail-mounted industrial heat-treatment systems designed for intense heat processing—commonly operating between 750 °C and 1,250 °C (1,380–2,280 °F). Ideal for austenitizing, normalizing, forging reheat, and sintering, these furnaces excel in automotive, aerospace, steel, and heavy-equipment industries where large, oversized, or complex loads are routine.
With a movable “car” hearth, these furnaces allow loading/unloading outside the chamber, minimizing thermal shock and preserving furnace lining. They offer both energy efficiency and harsh environment durability.
| Component | Function | User Benefit |
| Rail-Mounted Car | Moves parts in/out via track | Safe loading, minimal damage, heavy/odd geometry handling |
| Heating System | Gas burners or electric (SiC, Fibrothal®) elements | High-temperature range, clean electric option available |
| Multi-Layer Insulation | Fiber blankets, Mega‑Block®, or brick with sealing | Minimal heat loss, robust thermal performance |
| PLC & Controls | Recipe management, PID zones, safety interlocks | Full traceability, integration, NAMCAP/AMS compliance |
| Door Seals | Pneumatic or mechanical lift seals | Maintain temperature, reduce air infiltration |
| Optional Quench Unit | Gas/oil/water quench options | Adapt to various processes like hardening or annealing |
| Process | Temperature | Atmosphere/Quench | Common Parts |
| Austenitizing | 900–1,250 °C | Usually air or inert | Steels prior to quench |
| Normalizing | 900–1,200 °C | Air cooling | Forged shafts, castings |
| Pre-Forge Reheat | 1,100–1,250 °C | Protective gas | Large forgings, wheels, aerospace bars |
| Sintering | 1,000–1,250 °C | nitrogen | Powder-metal parts, hard alloys |
| Annealing | 850–1,000 °C | Slow cool in air | Tool steels, stress relief |
| Feature | High‑Temp Car Bottom | Batch Box Furnace | Vacuum Pit Furnace |
| Max Temp | 1,250 °C | ≈1,100 °C | ≈1,200 °C |
| Load Size | Up to 150 t | Small–mid-size loads | Moderate–large loads |
| Uniformity | Excellent (±5 °C) | Good to moderate ±10–20 °C | Excellent ±5 °C under vacuum |
| Heating Mode | Semi‑continuous | Batch (stop-start) | Batch with vacuum cycle |
| Atmosphere Options | Air, inert | Air, protective gas | High vacuum/quench variant |
| Energy Efficiency | High with fiber insulation & seals | Moderate–high depending insulation | High, electric but vacuum pump energy |
What maximum temperature can be reached?
Up to 1,250 °C (2,280 °F) with gas or electric heating—covering all high-temperature processes
How uniform is the heat zone?
Achieves ±10 °F (±5 °C) across the chamber with proper zoning and insulation .
Are electric-only models available?
Yes—fully electric versions using fiber modules (e.g., Kanthal Fibrothal®) offer clean, efficient heating
What atmosphere control options exist?
Flexibility includes air, nitrogen and quench medium as needed—ideal for oxidation-sensitive or critical alloy processes.
Can this integrate into Industry 4.0?
Absolutely—PLC & HMI with MES connectivity, full data logging, recipe control, and traceability are standard.
What capacity range is possible?
From a few tons to 150+ t per charge, tailored to your production scale
