RINGFEDER® has designed a special damping solution for the application in the arc furnace of steel works, which involves specific requirements as to temperature and load resistance. The melting furnace serves to melt very large and heavy parts of steel scrap (e.g. engine blocks), which fall into the melt from a height of up to ten metres. By the use of a variety of industrial buffers based on RINGFEDER® friction springs, which are provided with an absorption capacity of several ten thousand Joule, the drop energy generated is effectively absorbed, protecting the overall construction against damage. The complex development work specially focussed on the attainment of maximum functional reliability and zero maintenance at continuous furnace operation with temperatures of several thousand degrees Celsius. Because downtimes due to damage would cause great losses.
