Material used in the manufacture of these refractory replacement parts is chosen based on the very latest technical knowledge. In addition to absolute pressure tightness, this means maximum mechanical abrasion resistance can be achieved. Components are pre-dried at around 500ºC at the StrikoWestofen factory, almost completely eliminating the risk of later contamination of the melt with hydrogen.
Holger Stephan, who manages the Service and Spare Parts division at StrikoWestofen, explains: “For us, good support doesn’t end when a new foundry system is installed. We’re at your side throughout the entire service life of a furnace to ensure maximum productivity around the clock.” The new relining method has proven its worth many times over. High-end die-casting specialist Alupress in Hildburghausen, Germany, is a case in point. A refractory replacement part from StrikoWestofen has been in use there for four years now.
Enrico Sonnefeld, head of maintenance at Alupress, comments: “Not only does our dosing furnace still look like new – it continues to provide optimum results as well. In our opinion, relining using a refractory replacement part is definitely to be recommended.”
The investment is worthwhile in more than one way: a refractory replacement part is not just fitted in a flash, it increases furnace efficiency too. Holger adds: “Our customers are reporting energy savings of up to 30% compared to a non-original relining. That shows us we’re on the right track.”
