AUMUND NEWS 2//2020 – Products. Projects. Progress.
Your Partner in Metallurgy Worldwide.
AUMUND Group technologies provide solutions for numerous conveying applications in ferrous and non-ferrous metallurgy as well as in foundries.
Specific expertise and an excellent position in the market are in evidence in specialized conveying equipment adapted to materials at temperatures of up to 1100 °C, optionally incorporating the use of inert gas, as wellas in technology for cooling iron briquettes and similar materials without damaging them.
AUMUND equipment for metallurgy
For the different process stages in Iron and Steel plants AUMUND provides solutions and products for
- Conveying and storing of coal, iron ore or limestone
- Conveying of DRI, HBI, HCI, Fe-Pellets, Fe-Sinter and coke up to 1100 °C
- Conveying in inert atmosphere or seal gas
- Conveying and smooth cooling of HBI
- Additional cooling of Fe-Pellets orFe-Sinter
- Conveying of various kinds of hot and cold scrap or residuals
- Conversions or retrofits of existing material handling equipment
Direct reduction process
AUMUND has developed innovative conveyors to take hot DRI (direct reduced iron or sponge iron) either from the MIDREX shaft furnace or in other processes from the rotary hearth, rotary furnace or fluidized bed. This means sfor example that the material can be directly charged into an electric-arc furnace (EAF) while it is still hot. Several specialapplications have been developed for this technological environment. AUMUND’s hot material and cooling conveyors are unmatched internationally.
Sinter is conveyed at temperatures of up to 1100 °C from the sintering plant to the cooler, or after the cooler if the material is still too hot for standard belt conveyors.
Main advantages and characteristics of the AUMUND sinter conveyor:
- Lower energy requirement and lower noise emissions, therefore better working conditions in comparison to vibrating conveyors
- As relative motion between the sinter and the conveyor is eliminated, wear and sinter break-up are reduced
- The precise, overlapping design of the conveyor pans minimizes spillage
- Low maintenanc
Modern sinter shaft coolers utilize energy from the hot sinter and are connected by insulated AUMUND sinter conveyors in order to optimize energy recovery.
In cases where the main cooler does not cool the pellets sufficiently, an AUMUND conveyor acts as extended cooling line. It is designed with special air flow features and dedusting at the inlet. Thus additional air cooling of hot pellets is provided.
Controlled, slow cooling down (“smooth cooling” rather than in a quenching tank) of the HBI on the patented AUMUND cooling conveyor with a mixture of mist and air for high quality briquettes.
Main advantages and characteristics of the AUMUND HBI cooling conveyor:
- Cooling with the aid of a defined water mist but with low water consumption
- Avoidance of sludge formation
- Clean environment due to closed system
- Improvement of the HBI quality by slow cooling
