Abstract
The necessity of obtaining high quality castings forces both researchers and producers to undertake research in the field of moulding sands. The key is to obtain moulding and core sands which will ensure relevant technological parameters along with high environmental standards. The most important group in this research constitutes of moulding sands with hydrated sodium silicate. The aim of the article is to propose optimize d parameters of hardening process of moulding sands with hydrated sodium silicate prepared in warm - box technology. This work focuses on mechanical and thermal deformation of moulding sands with hydrated sodi um silicate and inorganic additives prepared in warm - box technology. Tested m oulding sands were hardened in the temperature of 140 o C for different time periods. Bending strength, thermal deformation and thermal degradation was tested. Chosen parameters were tested immediately after hardening and after 1h of cooling. Conducted research proved that it is possible to eliminate inorganic additives from moulding sands compositions. Moulding sands without additives have good enough strength properties and their e conomic and ecological character is improved.
