Furnaces for Hardening Long Components
We design and manufacture industrial chamber furnaces dedicated to hardening, annealing, and stress relieving long workpieces (drive shafts, pipes, spindles, guillotine blades, and long punches). We guarantee ideal temperature distribution along the entire length of the working chamber.
Design Tailored for Long Charges
Advanced thermal engineering eliminating distortion and temperature drop at chamber ends
Tailored to Customer Requirements
We deliver solutions customized to customer specifications.
Energy-Efficient Insulation
The use of lightweight fiber boards with low thermal mass guarantees rapid heating, low power consumption, and a cool outer shell.
Efficient Loading of Long Charges
A reinforced hearth made of fireclay plates or silicon carbide (SiC) enables safe sliding and positioning of heavy steel components.
Basic Dimensions
Calculated chamber capacity in liters and power parameters
| Capacity | Chamber dimensions [W x H x D mm] | Loading method | Maximum temperature [°C] | Power [kW] |
|---|---|---|---|---|
| 51 L | 300 x 200 x 850 | side-loading | 1150 | 6.5 |
| 60 L | 300 x 200 x 1000 | side-loading | 1150 | 10 |

* Hearth reinforcement: Optional silicon carbide (SiC) plate (10 mm) prevents scratches and mechanical damage to the floor under heavy loads.
* Opening options: Side-opening door, top-lifting (pneumatic/manual), or dual-sided pass-through access.
