Tilt rotary furnaces

The high performance ‘TR’ tilting rotary furnace is the latest addition to the OTTO JUNKER Group’s melting furnace range, representing the most effective melting furnace technology for processing mixed scrap and drosses.

The OTTO JUNKER TR is able to process many types of scrap including:

• Drosses.
• Mixed scrap often with contamination. (Tense Taint tabor etc.).
• Turnings / swarf / chips.
• UBC
• Scrap contaminated with iron and steel inclusions.

The TR tilt rotary from OTTO JUNKER UK

OTTO JUNKER (UK) Ltd’s range of high performance Tilt Rotary (TR) furnaces combine advanced melting technology, process control and high quality engineering, in the tradition of all OTTO JUNKER Group equipment. Aimed primarily at recycling applications, the advantages and flexibility of the TR continues to deliver savings and efficiencies throughout the aluminium industry. The TR technology is upgrading traditional industry equipment and finding new applications. For example the TR can deliver outstanding energy saving and productivity as a bulk melter for die-casting applications. For melting mixed, contaminated scrap including oxidised materials such as dross, the combination of low energy, high metal recovery and flexibility of feedstock, have shown the TR to be state-of-the-art technology.

Comparing the OTTO JUNKER UK TR to other traditional rotary and fuel fired reverberatory furnaces shows significant savings:

• Low energy – typically 25 % saving.
• High metal recovery 3 – 5 % increase in recovery.
• Improved productivity – cycle times improves by 50 %.
• Savings in labour – fully automated process – one operator able to use more than one furnace for example.

Advantages of the OTTO JUNKER tilt rotary

The latest TR furnaces from OTTO JUNKER UK deliver savings and efficiencies by using proven innovative design backed by in-depth process knowledge.

TR furnaces are offered with the following:

• Choice of fuels to suit local conditions, oil, gas, if available, with or without oxygen (oxy-fuel).
• Double pass burner firing with ‘proportionator’ combustion system to meter and mix the precise ratio of fuel (carbon) to oxidant (air or oxygen).
• ‘Proportionator’ - accurate real time ratio control gives maximum fuel efficiency and process control. For example to ‘oxidise’ smoke during the start of a charge or to fire with ‘reducing’ atmosphere and save metal oxidation.
• Unique door arrangement, enabling the furnace to tilt and fire simultaneously. This gives better mixing of the charge, faster melting and higher metal recovery.
• Fast charging of all types of scrap, even oversize bulky materials, door openings available up to 2 m internal dia. Fully integrated charging machines. Fast charging means faster melting, less energy and more production.
• Variable melting angles. The TR door design enables the furnace body to be reclined to maximise load capacity.

All of the furnace controls and functions are controlled using the latest PLC and SCADA software, communicated to the operator by a full size colour HMI (Human Machine Interface) monitor. The data communicated to the central PLC from the various furnace sensors are displayed and stored. Data including energy consumption, process temperatures and melt results etc., are available to print and transmit via ‘Ethernet’ or wireless applications to remote locations. The TR range is available in a number of standard capacities from 1 – 20T.
