Assessment of Foundry Chromite Sand Crushability under Thermal-Mechanical Loading [PDF]
Archives of Foundry Engineering, 2023 When used for sand casting, foundry sand is stressed in several ways. These stresses, thermal and mechanical, compromise the grain integrity, resulting in size reduction and the production of small particles to the point where the sand is no longer ...
