Thermal physical and mechanical properties of raw sands

2017-11-21  Blended sand is made by adding a bond to a ‘washed and dried’ or unboned base sand. This unbonded sand is sometimes called ’sharp sand’, however, the name has nothing about the actual grain shape. The unbonded base sand may be silica, olivine, zircon and others. Each sand has properties that make its use desirable in certain situations [8].

Investigation of Heat Transfer at the Mold/Metal

2005-12-16  Heat transfer between a solidifying casting and the mold is critical for achievement of high quality in the cast product. This is especially important in permanent mold casting where the rate limiting steps for heat transfer between the casting and the mold are primarily controlled by conditions at the mold-metal interface.
