Rapid but systematic cooling of Al-alloy ingots with ILTEC

At the moment the fields of application for the ILTEC Technology are further widened, at the Montanuniversität Leoben, Chair of Nonferrous Metallurgy. 

In order to create defined amounts and distribution of precipitation phases in different aluminum alloys, lab scale tests are performed in the labs of the Montanuniversität. With our small ILTEC test facility, the Al-alloy ingots are casted at different cooling rates realized by modification of the mould preheating temperatures and the heat removal with the ILTEC facility. By precise temperature measurements within the casted ingot piece and a subsequent microscopic analyses and mechanical testing, the optimized cooling conditions can be defined. 

Industrial scale implementation of these test results can lead to improved process routes and finally to better qualities of casted aluminum products.

Implementation of a parallel flow device in a pickling tank

In September 2018, a new and innovative approach to the use of the parallel flow device (PFD) was implemented at voestalpine BÖHLER Bleche GmbH & Co KG in Mürzzuschlag, Austria. Altogether, the installation comprises of three elements for improving the performance in the pickling tank and saving hydrofluoric acid.

For a better movement and thus optimised kinetics of the pickling process, the acid circulates through a series of nozzles via a parallel flow device at the top end of the tank. This provides a perfectly guided flow to ensure a more homogeneous acid distribution.
In order to prevent the overheating of the acid, the steam injection is circumvented by the implementation of an instantaneous heating unit. This ensures a constant but adjustable temperature in the entire tank. 
As another benefit resulting from the circulation of the acid, a filtering unit is installed at the intake socket of the pump. This filtering unit can be removed and the suspended solids collected in the filter can be removed periodically.

The given drawing shows the assembly of the unit.

With the overall aim to save time for pickling, safe hydrofluoric acid by temperature control and filtering unit and safe costs by stop using the steam generator, we are convinced to set new standards in pickling units together with voestalpine BÖHLER Bleche GmbH & Co KG.
