Main Structure: made of UPN-IPN-IPE and HEB REINFORCED iron profiles. This structure is covered on the inside with a 4 mm thick steel plate. The structures are fully assembled with all the elements of which they are built, including burners, tubes, transducers, etc. as well as refractory insulation materials. All metal parts are coated with a heat-resistant anticorrosive primer, the exterior finish is painted.
- Sight Glass: 3 observation windows measuring 100x100 mm made of rock crystal that can withstand high temperatures can be installed (on request).
Isolation: The thermal insulation of the furnace is achieved by a combination of three elements: Ceramic fibre inner lining, the second layer of insulation using refractory bricks and the third layer of refractory bricks of ISO-170/ASTM-33 classification.
