Heat Transfer Properties of Some Kinds of Sand Molds

The mean values (25-1,300°C) of specific heat of these molds are 0.25CGS unit for silica sand, 0.26CGS unit for olivine sand, 0.18CGS unit for zircon sand and 0.21CGS unit for chromite sand. With the measured values of thermal conductivity, specific heat and mold density, thermal diffusibility and heat diffusibility of each mold were calculated and used for thermal analysis when molten steel was poured

Chromite Emerges as a New-Age Molding Material

2011-12-4  Chromite also provides very good heat transfer, allowing a skin to form easily on the surface of the casting to reduce penetration. “It also provides better grain-to-grain contact,” Patterson said of SpheriChrome, “so, especially with the conductivity of the chromite there is better heat transfer with that round grain, combined with the chemical makeup of the chromite.”

2017-6-9  Hevi sand is produced from high grade foundry chromite sand that has been specially treated for use as a mould and core media to produce quality castings. It is selectively mined from AMCOL’s South African mines which are among the richest and purest chromite deposits in the world. Hevi sand is a unique aggregate prepared for traditionally difficult metal casting applications. Its unique characteristics allow foundry men to produce excellent castings. Its good density provides the mould or core with a high rate of heat transfer

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].
