It is the increasing demand for an economic and cost saving operation mode that requires effective cooling in order to achieve low refractory wear and good furnace lifetime, which is making cooling technology a sustainable aspect of furnace operation. In addition, safety awareness is becoming more and more a focal point of the operating philosophy. However, the use of water - today’s standard cooling medium - has major drawbacks as it can cause problems during furnace start up and operation, namely hydration problems, corrosion and explosion. Not to forget the severe personal as well as economic damage in case of a malfunctioning water cooling systems. ILTEC is a new patented cooling technology, developed by Mettop GmbH in Austria, to overcome the disadvantages of water by using an alternative cooling medium, namely the ionic liquid IL-B2001. IL-B2001 is non-flammable, non-corrosive, non-toxic and minimizes explosions due its low vapor pressure. It also has a wide liquidus range and operating temperatures between -15 and 200 °C. These properties all contribute to the safe use of IL-B2001 in various cooling applications in the non-ferrous metal processing as well as iron and steel industry wherever there is a risk of cooling water explosions. This paper will emphasize potential applications for the lead and zinc industry as well as general non-ferrous metals industry. It will highlight safety related items, the use of the ILITEC Technology for energy recovery and new process routes that are made possible.
