Mobile Test Unit ALSP highline combines two measuring procedures. The purity and thus the quality of the melt is determined by the density index measurements. The integrated Thermal Analysis TA 12.13 determines the grain refinement and modification to evaluate the mechanical properties of the casting. The goal of reducing rejects, thereby saving resources, is made possible by continuous melt monitoring using ALSP highline.

Information on individual processes:

The hardware and design of ALSP highline, incl. pre-heating chamber, allows the operator to take very accurate measurements while working comfortably. It has been designed for daily use in the harsh foundry environment. The balance stands on a raised, vibration-damped steel plate. A cooling water vessel for the density samples and a storage facility for the casting ladle supplied with the balance enable an efficient workflow. The thermo stand for Thermal Analysis is fixed on the robust aluminium work plate. The base of the unit offers two large storage compartments, one of which has a lockable door. Due to the smooth-running and heat-resistant castors, ALSP highline can be used flexibly at different stations or furnaces.

The associated MeltBoard PC software allows the tabular and graphic display of individual measurements and measurement series. The standardised comparability, evaluation and archiving of all measurement results are ensured, as is the use for internal and external reporting. The pre-configured standard report can be customised and extended with your own functionality.

Basis of integrated Thermal Analysis TA 12.13

The new hardware specially developed for Thermal Analysis TA 12.13 enables very accurate measurements and was designed for daily use in the rough foundry environment. Various laboratory and field tests of different Al alloys were microscopically evaluated by means of specially prepared polished sections and chemical treatment of the polished surfaces for grain boundary determination. The grain size was determined by measuring approx. 100 grains per section in two axes and then calculating the average value. The dimensionless grain refinement number is based on the grain size table of the American ASTM standard. Thus, the TA 12.13 anticipates the time-consuming procedure of a polished specimen preparatio and enables a standardised comparison of specimens.

Thermocouple, crucible and protection tube

The sensor stand was specially developed for the Thermal Analysis and contains a permanent thermocouple for direct measurement. The thermocouples comply
with class 1 (NiCr-Ni) and their deviations are tested by mk. These can be stored in the monitoring unit and therefore taken into account during test work.

The durable stainless-steel crucible has a capacity of 90 g for molten Al.

Protection tube
Thermal Analysis samples along with the embedded stainless-steel tube can be returned directly to the melt where they dissolve without leaving any troublesome
ceramic or sand residues.
