Foundry sand once used must be thoroughly water scrubbed and water washed to remove objectional bonding materials, clay slimes, and fines. Such treatment will greatly extend the life of the sand and will cut to a minimum the requirements for new sand. Foundry castings made from molds using this reclaimed sand, can also be maintained up to the ...
May 07, 2020· Foundry sand is clean, uniformly sized, high quality silica sand, used in foundry casting processes. The sand is bonded to form molds or patterns used for ferrous (iron and steel) and nonferrous (copper, aluminum, brass) metal castings. Shakeout sand from completed metal casting are often reclaimed back into the foundry sand process. CASTING ...
The importance of foundry coating in improving the surface quality of casting cannot be over emphasized. The application of mould and core washes creates a high thermal integrity barrier between the metal and the mould resulting in the reduction of thermal shock experienced by the sand system.
Sand Washing and Desliming. Silica sand pumped from the pit is passed over a screen, either stationary, revolving or vibrating type, to remove tramp oversize.
