This is a directly heated heat-treating furnace that is designed for intermittent operation and with a rectangular chamber and floor-level loading. The elevator platforming top hat has ceramic fibre insulation and is fitted with electric resistance heating and a very powerful circulation and cooling fan for ensuring even heat transfer to the charge. Products to be heat-treated are placed in a basket before being put in the hearth by means of an overhead crane. When the loading is complete, the top hat is lowered to enclose the furnace space. After the heat treatment process, the top hat is raised and the batch is removed.


Annealing and normalisation of the products of various sizes mass-produced by the iron and steel industry.

Our core business is the manufacture of industrial furnaces and thermal process equipment in accordance with the customer’s process specifications and technical requirements.

We provide troubleshooting, regular or occasional maintenance, as well as the renewal and upgrade of industrial furnaces.

Our company has gained a lot of experience in the construction of steel structures. We ourselves do minor cutting works, while, for doing large-scale ones, we cooperate with highly experienced professional companies.

We undertake the annealing and stress relieving heat treatment of large and heavy workpieces in the furnace.
