OTTO JUNKER and the THERMCON brand have long been synonymous with advanced industrial furnace technology and plant engineering. A world leader in its markets, our company has specialized in the supply of aluminium foundry and casthouse equipment. A powerful partner in furnace engineering and process automation. Installations for melting and casting aluminium, drying processes, heat recovery, burner installations, furnace modernization projects and process automation systems form the backbone of OTTO JUNKER's product range. Our extensive know-how and experience in furnace and plant design,...

Determine all problems impartially, identify a solution through joint academic and industrial enterprise, and deliver the result to the customer in the form of quality products. Process competence: Supplying complex processing lines from a "one-stop" source is our business. OTTO JUNKER's product range covers the full process chain from melting equipment (sophisticated foundry systems, both induction-type and fuel-fired) to heat treatment systems (pre-heating, annealing, homogenizing, quenching and tempering, artificial ageing, handling and finishing technology). Technological competence:...

OTTO JUNKER offers a wide range of ingot and scrap charging machines of THERMCON design. These systems contribute in a major way to the productivity and safety of any aluminium melting operation. The charging time per batch is less than three minutes. Feedstock can be moved deep into the furnace so as to maximize the charging volume right from the start of the melting cycle. Our charging machines are custom designed for use with existing or new furnaces and can be provided with very wide (7 meters+) and long containers to match virtually any furnace configuration. Wide containers provide...

OTTO JUNKER skimming machines of THERMCON design prove highly effective tools in every casthouse operation. Replacing the primitive method of skimming by forklift with long rake attached to it, the THERMCON skimming machine performs this job much more efficiently and quickly. All machine movements (e.g., floor travel, movements of the telescopic boom) are hydraulically powered. However, no part of the hydraulic system projects into the furnace. The telescopic boom effectively minimizes the skimming machine's space requirements. Further advantages: ■ Safety - the operator stands well...

I Hearth-type melting furnaces OTTO JUNKER supplies a broad range of custom-designed melting furnaces for any production processes employed in the aluminium industry - from DC casting of rolling slabs, T-bars and extrusion billets, sheet or plate through to wire/rod making, conventional ingot casting lines, etc. Dry-hearth furnace systems are a reliable solution for melting down ingots, sows and heavy scrap containing a free ferrous portion (e.g., automotive castings). The iron content is reclaimed from the dry hearth once the aluminium scrap has molten down. ■ Melting rates: 1 - 30...

Multichamber furnaces with integrated fume treatment facilities and heat recovery for preheating the charge material are supplied to the secondary aluminium industry. The systems are suitable to recycle contaminated aluminium in an environmentally sound manner, meeting or exceeding the strictest clean air legislation even with respect to dioxin emissions. Feedstock can be charged into this particular furnace type at three different points: Ingot material intended to form the molten heel at start-up, for correction of alloys or to enhance the melting rate can be charged on the dry ramp in...

OTTO JUNKER supplies a broad range of custom-designed holding and pouring furnaces for any production process employed in the aluminium industry - from DC casting of rolling slabs, T-bars, extrusion billets, sheet or plate through to wire/rod making, conventional ingot casting lines etc. These furnaces can be either stationary or tilting and are suitable for alloying, holding and pouring operations. ■ Capacities: 2 - 150 tons ■ Available heating systems: ■ ambient air burners for gas, light or heavy fuel oil ■ electric heating elements Design features: ■ Cascade-free pouring of liquid metal...

Launder systems are an essential part of any casthouse. Well designed launders contribute to a smooth and efficient casthouse operation where fast transfers between furnaces are of key importance. Clean, low-turbulence casting launders play a significant role in producing high quality products. OTTO JUNKER has outstanding experience in designing and installing launder systems. This expertise is supported by the company's own proprietary software program for the design of open and closed launder systems, the use of the most advanced launder lining materials, and launder (pre-) heating...

Billet handling systems Available billet handling solutions range from manually operated billet grabbers to fully automated systems which provide automatic billet stacking from the moment the billets are put on the table (the entry of an automatic billet handling system) for processing through the homogenizing furnace, the cooling chamber and the billet saw. The whole process is controlled by a dedicated PLC system that moves the billets from the entry point to the exit of the billet saw, based on menus in which the heat treatment curve in the homogenizing furnace, the cooling cycle in the...

OTTO JUNKER batch-type homogenizing furnaces for extrusion billets can homogenize a wide range of billet sizes to very close temperature tolerances. Batch-type homogenizing furnaces provide the necessary flexibility wherever billets are produced in many different diameters and alloys. The furnaces together with the charging machine operate semi-automatically. Control is effected by PLC systems with HMI interfaces that allow control of the process via menus for each size and alloy plus additional custom-designed menus. Thus, each batch can be treated in accordance with the special...
