Selfsetting sands with furan resins are still the largest use of SMS with synthetic resins. They can be used to prepare such forms and cores - of different sizes and shapes, for casting all type alloys [1-3]. A reclamation of spent moulding sands, as a recycling method of waste foundry materials, originated from the casting production cycle, constitutes a very serious problem of each foundry plant, related first of all to the environment protection and also to the rational material management.
The results of furan resin sands strength tests from the matrix of pure quartz sand reclaimed was performed on the test apparatus AT-2. Sand sieve analysis was made of fresh and reclaimed material, and loss on ignition tests conducted on reclaimed material, obtained at different times of reclamation treedment. Granulation tests of post out reclamation dust, obtained from the sand were also carried of furan resin.
