Before: Thermographic images of the existing situation form the basis for the modernization concept of the AE-Group. The images allow StrikoWestofen to evaluate the places in the furnace at which most heat escapes.
After: The relining to OEM quality achieves energy efficiency values comparable to those of current models: a total of 14 Westomat dosing furnaces operated by the AE-Group will be modernized by StrikoWestofen in the months to come.
A German manufacturer of thermal processing technology will upgrade the refractory lining and modernize 14 Westomat dosing furnaces operated by AE-Group, Gerstungen, Germany.
StrikoWestofen Group, Gummersbach, Germany, won the contract, and its extensive measurements and thermographs allowed the Gummersbach, Germany-based company to identify additional opportunities for optimizing the refractory design.
“After operation periods of up to 17 years, it has now become necessary to reline the existing systems,” says Holger Stephan, manager of the service und spare parts department at StrikoWestofen. “In the context of a comprehensive modernization, we will reduce the energy consumption by up to five percent.”
The refractory lining of a dosing furnace makes a significant contribution to its efficiency. New Westomat dosing furnaces supplied by StrikoWestofen Group have a refractory lining that is specifically designed in terms of angles and processes occurring in the furnace chamber and with regard to the materials used.
The AE group, which has several locations in Germany and Poland, has decided to retrofit its existing dosing furnaces, combining the necessary relining with updating the layout of the furnace chamber. The high-pressure die-casting company has been operating Westomat dosing furnaces for several years now.
In the context of their consulting services, the technicians from StrikoWestofen carried out a detailed analysis of the existing situation. This included measurements of the current energy consumption as well as thermographic images. “The thermographs clearly show the places in the furnace at which the most heat is lost. In close cooperation with Mr. Drehmann, maintenance manager at the AE-Group, we have worked out an extensive modernization schedule on the basis of these images,” Stephan explains.
