Product category: Graphite electrodes

Graphite electrodes

Graphite electrodes for electric arc furnaces (EAF, LF, fusion)
Graphite Materials, with headquarters in Zirndorf, Germany is a partner of an experienced Chinese manufacturer and distributes graphite electrodes in Europe under its own name. The diameters range from 75 mm to 600 mm in established grades RP, HD, HP, SHP and UHP. Lengths depend on the diameter with a maximum length of 2,700 mm. Tools such as transport nipples, threaded hooks and torque wrenches are available for electrode assembly. Our offer also includes advice on processing broken electrodes, qualified application support and on-site service when good advice is needed.
Customers benefit in particular from the control system for electrode screw fittings using thread gauges that was developed in 2007. The system is based on high-quality CNC processing. Thread gauges are used to measure thread tolerances. Practical knowledge gained over the course of 20 years has enabled us to define tolerances for the optimum electrode connection and this is apparent to the customer in the form of a low level of consumption.

Product category: Resistance heating devices

Heating via electrical resistance

Heating via electrical resistance
When an electrical current flows through graphite or C/C (carbon-carbon), the electrical resistance of the material generates heat. We design and calculate heating systems up to 2,500°C. Our modern CNC-controlled machines are used to manufacture rods, tubes, curved flat heating elements, plate heaters and meander heaters. The dimensions of the connection bridges and electrode transitions are optimised. The total resistance of each heating system is measured before delivery and documented in a test record.

Graphite components

Graphite components for high-temperature applications
Over a production area of 3200 m2, 30 employees produce graphite, CC and insulation components in both small series and mass production. In particular, we specialise in individual single parts.
Working under one roof, Materials Engineering, Design and Production develop system solutions for vacuum and inert-gas furnaces.
The spectrum of graphite components ranges from lightweight sleeves weighing just 5g to muffles weighing 500 kg.

Carbon-fibre insulation

Carbon-fibre insulation made of soft and hard felts
With 20 years of practical experience, we have become established on the market as a specialist in carbon-fibre insulation. We offer insulation for rectangular chambers, which is made of hardened felt boards, soft felt or a combination of hard and soft felt.
We offer one and multi-piece insulation cylinders for round furnaces in various designs.
Diameters range from 300 to 1600 mm, and lengths from 600 mm to 3,600 mm.
The process temperature of the furnaces ranges from 1300° to 2500°C in inert gas or a vacuum.
With our insulation concepts, we supply furnace manufacturers who produce heat-treatment and soldering installations, pressure-sintering furnaces up to 100 bar, hot-isostatic presses (HIP) and crystal-growing systems.
Applications range from the automotive and aviation industry to carbide production and the solar industry.

Product category: Fans


Fans for directed gas flows
Fans and fan wheels made of C/C (carbon-carbon) are used to circulate hot gases in vacuum and inert-gas furnaces. Using fluid mechanics principles, an innovative fan wheel has been developed that creates a directed gas flow, similarly to a fan.
Thanks to new approaches in design and production, it has been possible to create a purely positive-locking connection technology without screws.
This fan is particularly effective when used in cylindrical furnace chambers.
Conventional paddle fans often fail when a paddle breaks at the shaft collar. A modification to the design and manufacturing strategy has greatly increased the service life of the fan.
We have developed other components, such as CC diffusers, to control gas flows in quenching furnaces.
