Reheat furnace

A complete solution to meet the demands for saving energy along with environmental protection.


Making the most of scarce resources, preserving the environment, and using energy in an efficient way are the megatrends of our times.

Controlled incineration processes under technically optimized circumstances provide one part of the answer.

Well-constructed boilers and modern power plants contribute valuable energy and give their share in an integrated approach to waste management.

„The way we consume and produce energy is a major concern of our times. Top-notch power plants and reheat furnaces push the technical frontier with a multitude of fuels and applications. This places special demands on the refractory materials used. It is a joy to face and solve these technical challenges for our clients.“

Research and sustainable development

Seven has incorporated environmental concerns about climate change in its innovative approach to the market; not only in making our factory fully electrically independent by using renewable energy sources, but in the entire manufacturing process cycle and quality control.


Selection of the raw materials, dedicated and oriented research, composition architecture and on the field technical experts are the key-points for outstanding efficiency and reliability of the refractory linings, excellent control of the thermal load distribution and low product variability in time.

Engineering and solutions

The construction of any reheating furnace has several solutions, by either adopting the classical brick lining or combination with monolithic materials. The installation techniques are various depending on materials used, i.e. casting, ramming, gunning or shotcreting. In some furnaces precast pieces may even be considered.


The target in terms of technology, time frame, type of installation and available budget may address and/or influence the engineering solution.
