The requirements of the thermal process, such as temperature and productivity, are decisive for the furnace design. ANDRITZ Metals distinguishes between continuously and batch-wise operating furnaces. In continuously operating furnaces, the charging material is transported through the furnace at a constant speed or step by step and is heated at the same time.
These types of furnace are used for reheating of semi-finished products (slabs, blocks, billets, etc.) for subsequent hot forming or heat treatment. Due to the fast heating and cooling rates, it is possible to produce steel grades meeting stringent demands in terms of the temperature-time-curve. Overall, the performance capacities of continuous furnace systems are higher than those of industrial furnaces with batch-type operation.
