ROLLER HEARTH FURNACE FOR NONFERROUS STEEL TUBES AND BARS 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. Pipes, bars and other semi-finished products made from non-ferrous metals, including wire coils, are becoming increasingly important throughout industry. Roller hearth furnace plants can be used to treat a very wide range of products which are used in all industrial sectors. Economical, energy-efficient heat treatment plants are essential to meet the growing requirements faced by materials, such as increased cleanliness in the pharmaceutical industry and weight reduction without sacrificing strength and other properties in the automobile industry, and to produce large quantities of materials required throughout the world. The heat treatment is an essential stage in the production and processing of pipes and bars made from non-ferrous metals. This heat treatment is mainly carried out in roller hearth furnaces, which may either be electrically heated or gas-fired. The main heat treatment processes under protective gas atmosphere in a roller hearth furnace plant are bright annealing in combination with Stress relief Recrystallization (Soft Annealing) Homogenization Annealing Precipitation Hardening
