The melting furnaces MF are used for the energy-efficient melting of clean input material such as block metal or clean production return scrap. The melting furnaces MF are used for the energy-efficient melting of clean input material such as block metal or clean production return scrap. Design Depending on the conditions at our customer's works, we propose stationary or tilting furnaces. The MF, the tiltable ones feature a fully cardan suspension of the hydraulic tilting cylinders, which ensures a continuous and precisely control of the tilting movement. Moreover, this design guarantees that the cylinder is free from bending forces, which in turn leads to a longer service life of its gaskets. The furnaces are equipped with large doors for easy carging and cleaning. The doors are equipped with a hood that collects dust and flue gas while the furnace door is open. The smooth inner walls of the furnace chamber contribute to the easy and thorough cleaning. The furnaces can be equipped with rotary flux or gas injection and electromagnetic stirrers. Both improve homogeneity and quality of the melt. Heating Our melting furnaces are heated either with natural gas burners or electrically. Regenerative burners with a large flame volume are used for the optimum radiant or convective heat transfer and are characterized by a homogeneous heat impact to the bath surface. This results in a homogenous temperature distribution, a low formation of nitrogen oxides and an efficient heat recovery. Since the discharged waste gas preheats the combustion air in the regenerator, both the energy requirement and the waste gas temperature are reduced. The latter allows feeding the waste gas
