Furnace Systems for Aluminium Rolling Mills

OTTO JUNKER supplies all necessary heat treatment, melting and holding furnace equipment for the entire production workflow, from the casthouse to the hot mill and cold (strip / coil) rolling bay.

Our name stands for excellence in all aluminium mill applications, from fast ingot preheating and homogenizing to high-convection chamber annealing equipment for coils, continuous strip flotation furnaces and coiled-foil annealing lines. All these equipment types are developed, designed, delivered, installed and commissioned by OTTO JUNKER experts.

Furthermore, OTTO JUNKER builds all requisite ancillary equipment and handling systems for the above furnaces. These products include up/downenders, pushers and extractors for pusher furnaces, charging machines for chamber-type furnaces and cooling chambers, loading stations, protective atmosphere recooling systems, etc.

The entire process responsibility rests with OTTO JUNKER's highly skilled specialists. For every product, we have an expert team covering all fields of specialization.

OTTO JUNKER is committed to the objective of supplying its customers with high-grade technology. Energy efficiency and environmental compatibility are among our first and foremost concerns, in addition to our ongoing pursuit of improvements in power consumption, process management and general equipment design.

All equipment types embody the latest state of the art, whether in flow management, heating technology, enclosure design and mechanical engineering. For the customer, these benefits translate into high throughput rates, low energy consumption and ultra-close temperature tolerances. 



Advanced simulation methods are used to maximize heat transfer and temperature uniformity levels while reducing flow losses. Our clients will thus benefit from reliable, long-lived equipment based on rugged and dependable OTTO JUNKER designs.

Following their successful engineering, mechanical and flow model validation, new technologies are subjected to hot and cold trials in the test-bay before being refined and progressed to the marketability stage.
