Abstract
A proper management of sand grains of moulding sands requires knowing
basic properties of the spent matrix after casting knocking out. This
information is essential from the point of view of the proper performing
the matrix recycling process and preparing moulding sands with reclaimed
materials. The most important parameter informing on the matrix quality –
in case of moulding sands with organic binders after casting knocking out
– is their ignition loss. The methodology of estimating ignition loss of
spent moulding sands with organic binder– after casting knocking out -
developed in AGH, is presented in the paper. This method applies the
simulation MAGMA software, allowing to determine this moulding sand
parameter already at the stage of the production preparation.
