Highest efficiency, best quality, highest reliability and lowest emissions are the demand on every MEFKON heating system for the improvement of our customer’s profit.


Our main task is to find an optimal solution, especially when it comes to key issues such as a uniform temperature distribution, shortened heating times and less stress / strain tolerance of the refractory material and the efficiency increase of the whole system.
 
As MEFKON is not associated to producers of refractory material or components we are therefore able to integrate highest-quality products from burner, control and refractory technologies into our systems.

SECONDARY METALLURGY EQUIPMENT

RH heating systems are used for preheating and drying RH vessels and for secondary metallurgy treatment.

Our holistic technical understanding of all relevant processes and influencing factors form the basis of engineering our secondary metallurgy equipment such as combined blowing/burning lances, TOP burner lances or stirring systems.
