Pusher furnace systems are perfect, in terms of energy use and flow management, for preheating and homogenizing milled slabs prior to hot rolling. Their fully automatic operation, electronic functional interfacing with the hot rolling train and minimized energy consumption confirm the benefits of OTTO JUNKER's high convection technology embodied in this equipment type. The furnaces are built either as a single standalone system or in parallel arrangements of multiple units. Complex charging and discharging machines can thus serve several furnaces, with all associated investment cost benefits. All machines and furnace components are optimized for the given process and incorporate OTTO JUNKER's standards of rugged design. Furnace: Single or dual row charging, depending on slab size Flexible charging of differently sized slabs High convection technology for fast heating and cooling Highly efficient self-recuperative high velocity burners Temperature control based on metal temperature and numeric model data Heating and cooling without off-temperature currents by uniform introduction of heat flows into the recirculating furnace atmosphere Long-life low-friction skid systems ensuring a reliable and smooth slab transport
