Walking heart furnac#194C54The 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. castin, 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.
