SUMMARY:ionicLife cast technology - real copper in copper cast for tuyeres
DESCRIPTION:Mettop and WeCo have developed an innovative casting process enabling the only real copper-in-copper pipe cast by cooling with ionic liquid. The result is excellent metallurgical bond between copper tube and copper casting which leads to both long life time and recyclability of the copper cooler. Mettop and WeCo joined forces to develop this new safe production method for copper coolers aiming for improved thermal and mechanical properties and consequently extended lifetime not only limited to tuyeres. 
In order to get the best performance and the longest lifetime of these tuyeres it is best to use copper tubing for the cooling circuits. This entails the challenge of putting a thin metal structure into a surrounding with a large amount of liquid metal with a higher temperature then the melting point of the tube. Therefore a method we developed which allows sufficient refrigeration of a copper cooling circuit during the casting process in order to prevent the melting or deformation of the tube. As the cooling with gases is not sufficient and the use of water is extremely dangerous in presence of liquid metals - the only viable option keeping work safety in mind, is to cool with an Ionic Liquid. These liquids can be tailored in their characteristics in order to fit the application. In this case it is a cooling medium which can be used up to 250 °C and which is safe in handling and in case of direct contact to liquid metal. Mettop holds the patent to the only non-corrosive and non-toxic Ionic Liquid specifically designed for metallurgical applications – the IL-B2001. Therefore a co-operation between WeCo and Mettop has been formed in order to overcome the challenges of producing large cooling elements which are entirely made from copper in a safe way.
