Journal of the Southern African Institute of Mining and Metallurgy, 2022 During steelmaking, one important factor for production efficiency is the free opening of the ladle nozzle during continuous casting. Free opening occurs when the well filler sand and the steel flow freely when the slide gate is opened. Well filler sands

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 ...

Properties of furfuryl alcohol resins for conventional sand moulding and binder jetting applications [PDF]
MATEC Web of Conferences, 2022 This paper compares two commercial acid-cured furfuryl alcohol resins. The first material is used for conventional sand moulding (CSM), while the second material was manufactured for the binder jetting process (BJP) using a Voxeljet VX 1000 printer.
