This Car Bottom Furnace for Steel Tube Heating is specifically developed for precision thermal processing in the tube production industry. It meets the standards for Precision Tube Annealing Furnaces and Industrial Batch Heat Treatment Furnaces.
·Composite Fiber Insulation System
120 mm high-alumina fiber + 60 mm nano-microporous panels, with a hot-to-cold face temperature difference < 70 ℃.
·Micro-Bead Vacuum Insulating Bricks
Density only 0.8 g/cm³, compressive strength ≥ 6 MPa, thermal conductivity 0.18 W/(m·K).
·20° Upward Incline Design
Prevents resistance wires from sagging due to high temperatures, extending lifespan by 2.5 times.
·Replaceable Ceramic Liners
25 mm thick, shock resistance ≥ 50 J, and maintenance time < 30 minutes.
This intelligent structure suits both Gas-Fired Furnace and Electric Furnace configurations, making it ideal for Heavy-Duty Car Bottom Furnace use.
Advanced production lines with laser cutting and robotic welding ensure consistent quality and strength in this Industrial Furnace system.
| Process | Key Control Point | Inspection Method |
| Shell Welding | Continuous full welds, no undercutting | UT ultrasonic flaw detection |
| Refractory Brick Laying | Joint thickness ≤ 2 mm | Feeler gauge + infrared imaging |
| Resistance Strip Forming | Pitch tolerance ±1 mm | 3D coordinate measuring |
Each Batch Furnace passes strict quality control for long-term stable operation.
·The car-bottom track is pre-welded to the furnace frame, leveled at the factory. On-site steps:
1.Recheck with level meter →
2.Fix with expansion bolts →
3.24-hour natural settlement inspection
·Four-link Press Mechanism
Furnace door lowers → Side seal airbag inflates to 0.4 MPa → Air leakage < 2 m³/h
This structure reduces the need for foundation work, enabling rapid deployment and relocation.
| Test Item | Method | Result |
| No-Load Heating Time | Ambient → 1000 ℃ | 55 min (better than design spec of 60 min) |
| Temperature Uniformity | 9-point thermocouple test | Max deviation: 4 ℃ |
| Energy Consumption | Full load (1t tubes) | 0.34 m³ natural gas / 100 kg |
| Sealing Test | 500 Pa pressure hold | Pressure drop: 30 Pa/min |
These performance results exceed typical Tube Heat Treatment Furnace standards.
·Energy Savings: Saves 42,000 m³ of natural gas per year, equivalent to approx. ¥260,000.
·Foundation-Free Installation: Saves ¥80,000 in civil work; complete relocation in 7 days.
·Low Maintenance: Anti-sagging design increases resistance wire life from 6 to 15 months.
