Product category: Graphite and carbon shapes

Sintered plates for any requirement

For rods, drills or indexable inserts – we have the perfectly suited sintered plate for each of your products.

Depending on the requirements, we supply you with various sintered plates made out of graphite: the entire spectrum from extruded to isostatic pressed graphite. No matter if it’s a contoured or flat surface: we cover a wide range of geometries. We comply exactly with your specifications and ensure consistent processing quality.

C/C, a very light and stable material, offers significant advantages in comparison with graphite when used for sintered plates. We are happy to advise you regarding the switch from graphite to C/C sinter plates. We use FEM (finite element method) calculation to find the optimum plate thickness for your requirements in order to increase your productivity.

C/C grids (Machined and water-jet cut)

We work together with you to create optimum solutions based on your requirements and to find out which batch carrier will yield the best results for you. Schunk Carbon Technology produces both machined and water-jet cut C/C grids:

¬ machined grids made of C/C allow for a flexible design; the rigidity of the grid can be set precisely using the web height. They are particularly well suited for use with high weight loads with minimum deflection.

¬ water-jet cut C/C grids are ideal for low to medium weight loads. The water-jet cutting technology enables precise, low-cost machining in which even fine structures can be implemented.

Graphite and C/C components for CVD coating

For the CVD process, Schunk supplies all of the components made of graphite and C/C materials. These have

been proven in application and are best suited to meet the challenges of CVD coating.

For any desired dimensions and for simple or highly complex designs, we ensure consistent, high quality with our components made of graphite.

Due to its positive material properties, the use of C/C for charging plates offers particular advantages:

¬ increased productivity per production batch

¬ no brittle breakage behavior, so no batch loss

¬ improved ability to plan

¬ longer service life

¬ reuse by removing CVD coating layers

Coating removal – An innovative solution

When you coat your products, you also inadvertently coat your charging components. As soon as the layers begin to peel off (particle release), the service life of these components is at an end.
So that the production batches are not damaged, up to now the charging components have been scrapped.

With the professional removal of the coating on the charging components, we have developed a method for reprocessing and reusing the components, which saves resources and is cost-effective. The removal of the coating layer is primarily suited for use with C/C components because of its positive effect on costs.

Due to possible hairline cracks and brittle breakage behavior, charging plates made of graphite are only used for one application period. For this reason, cost-effective coating removal is not usually possible, with the exception
of a few components – e.g. solid graphite support rings. In contrast, coating removal allows C/C charging plates to be used for multiple and, moreover, longer application periods.

UniGrid® – Unique, modular, cost-effective

With UniGrid®, Schunk Carbon Technology offers not only customer-specific batch carriers, but also standardized solutions for C/C grids. In contrast to machined or water-jet cut grids, these grids, manufactured in a single, separate process, have a continuous fiber structure and no joints. The closed frame structure enables easy, uncomplicated handling with a high degree of rigidity and strength.

This modular batch carrier system offers a wide variety of possibilities for positioning graphite supports, this allows you the greatest possible flexibility when loading the grids. Our graphite supports are self-centering, both in our UniGrid ® grids and with respect to each other, this makes them easy to mount and align. The graphite supports can be stacked and offer excellent stability for multi-level structures.

C/C workpiece carriers

Disadvantages of traditional cast metal grids

Traditionally, workpiece carriers made of high-alloyed cast
materials are used in the heat treatment industry. However, at high temperatures, these systems have serious disadvantages. Due to the lack of creep strength, after just a few furnace runs the workpiece carriers are deformed, which can, in turn, result in the deformation of the treated parts.


Another disadvantage of cast materials is their high density and the associated high thermal capacity. When vacuum heat treating processes are carried out more often, particularly in conjunction with gas quenching, this can lead to poorer hardness results, greater part deformation, longer process times and increased reworking and process costs.
In addition, the deformation of the workpiece carrier prevents automated loading and unloading, which has a negative effect on throughput and economic efficiency.

Advantages of C/C workpiece carriers
Compared to steel, the properties of carbon fiber reinforced carbon materials (C/C) are ideal for workpiece carriers used in the higher temperature ranges because they offer many advantages, such as:
¬ high strength
¬ no deformation, even at high quench rates
¬ no reworking
¬ very long service life
¬ low density, so they are considerably lighter than steel
¬ reduction in thermal mass
¬ optimum ratio of workpiece carrier weight to part weight
¬ greater furnace loading and higher capacity
¬ higher productivity
¬ reduction in cycle time
¬ more consistent part hardness quality
¬ reduction in part distorsion
¬ less reworking
¬ greater quenching speed
¬ higher energy efficiency
¬ lower operational costs
¬ optional automated loading and unloading

Product category: Fans

Radial fan made of carbon-fiber-reinforced carbon

Advantages

¬ Significantly lower weight

¬ Maximum operating temperature at full revolutions (no throttling required)

¬ No creep, no deformation and no embrittlement equals longer service life

¬ More even temperature distribution and better heat transfer

¬ Improved energy and process efficiency

¬ Significantly higher efficiency than simple “paddle fans”

¬ One-piece impeller design, no screws and no joints

¬ Given the improved efficiency, hydrogen can be replaced with nitrogen

 

Operating conditions

¬ Protective atmosphere, e.g. nitrogen or argon

¬ Mixtures of hydrogen and nitrogen (e.g. 10 % H2, 90 % N2) are possible, depending on the dew point

¬ Higher hydrogen concentrations can be obtained by processing (C/SiC version)

¬ Maximum operating temperature up to 1600 °C, depending on the design and application

¬ Each atmosphere / application should be given special consideration

¬ Exposure tests using C/C materials should be carried out in advance

 

Design options

¬ Diameters up to 1000 mm can be achieved

¬ C/C version may be replicated from the original design

¬ Intelligent manufacturing allows a one-piece-design

¬ Connection via a C/C shaft or existing metal drive shaft is possible

¬ Balancing possible in C/C state; C/C counterweights

¬ 75 m/s peripheral speed
