Case study: Heating chamber lining

Efficient and durable lining

Companies in the heat treatment industry are regularly faced with the question of how heating chamber solutions can be reliably implemented or adapted to new processes. With the increasing complexity of modern components, the industry’s need for flexible, energy-efficient and durable furnace components is also growing. Consistently high product quality requires a reliable process, which in turn is based on sound expertise in furnace technology. Read here how Graphite Materials has optimised its customers’ furnace operations.

Background

High-temperature processes play a central role in many industrial sectors. A crucial component of these processes is the heating chamber lining. It ensures that the process runs reproducibly, efficiently and safely. The heating chamber lining is of particular importance in demanding industries such as the automotive and aerospace industries. It has a significant influence on both the service life of the furnace and the quality of the components.

The challenge

From design to revision, lining a furnace chamber requires above all technical expertise.
For the optimal lining of an industrial furnace, various materials are combined, the professional use of which requires comprehensive expertise in materials science and years of practical experience. This specific know-how forms the basis for a precisely fitting and durable heating chamber lining that is tailored exactly to the requirements of the respective furnace type and process.

The goal

A company in the automation industry needed a fully equipped heating chamber lining for a vacuum furnace. The aim was to optimise the furnace for soldering processes.

The basic conditions, such as installation space and target temperature, were available, but there was a lack of experience in material selection, design and calculation of a suitable insulation thickness and heating power. In addition, there was a need to redesign an existing chamber. Without the necessary expertise, there is a high risk that defined requirements will not be met and unnecessary costs will be incurred.

The company approached our Engineering Team, to find the ideal solution for the heating chamber lining. The requirements were:

  • Homogeneous temperature distribution in the furnace
  • Uniform heating performance
  • Gas ducting systems for targeted flow
  • Reliable sealing of doors and flaps
  • Guaranteed long service life of components
  • Service in the form of heating chamber inspections

Process results

A comprehensive heating chamber solution was implemented that was precisely tailored to the customer’s specific requirements: from consultation and design to final delivery in just two months. In addition to the structural design, short-term availability also played a key role. The customer is now able to implement the soldering process efficiently and reproducibly. In addition, there are prospects for future applications that go beyond soldering. Similar heating chamber linings are also known to be used for hardening processes

The result

The implementation led to several measurable improvements:

  • Effectiveness and efficiency through even temperature distribution throughout the entire installation space.
  • Sustainability through durable and thermally decoupled components.
  • Optimisation of process control through individually controllable heating ramps.
