Heat Treatment for Wire, Rods, Tubes and Bars: Products

Chamber furnaces are used for annealing and solution annealing processes of wire coils made of nonferrous alloys (e.g. nickel alloys, Inconel) or also special steels (e.g. duplex or high resistance steels) Furnaces can be custom-designed to meet the specific customer needs. Normally annealing processes require the presence close to the furnace of a dedicated tank for rapidly quenching the products.

LOI Thermprocess, with its predecessors Matthias Ludwig and Nassheuer, has been building bell-type annealing plants for more than 60 years. Throughout the world, more than 8500 LOI annealing bases have been installed. About 5000 of these bases operate with HNx controlled atmospheres. More than 3500 bases use HPH® annealing technology, with a proven atmosphere of pure hydrogen.

LOI Thermprocess, with its predecessors Matthias Ludwig and Nassheuer, has been building Continuous roller hearth furnace plants under protective gas atmosphere for tubes, bars, wire coils and semi-finished annealing goods for more than 60 years. Throughout the world, more than 350 LOI roller hearth furnace plants under protective gas atmosphere have been installed.
