Masters Theses


"The broad field of heat transfer is well developed in its theory and mathematics, however, some few applications of varying heat transfer rates have been explored only recently.

Previous to the nineteen-thirties, foundrymen had apparently been interested in heat transfer measurements only from the standpoint of the melting of metals and the heat treatment of the finished castings, with the rate of solidification and the transfer of heat from the casting through the mold being ignored, or at least accepted as an uncontrollable factor. This does not apply, of course, to the use of metal chills to adjust solidification rates of isolated areas of castings.

Perhaps the earliest intensive research on the subject of heat transfer in foundry sands under actual mold conditions was performed by Tanasawa in 1935, whose work is referred to by Jacob.

It is the intent of this thesis to investigate two of the many factors which affect the rate of heat transfer in the damp foundry mold. These two factors are 1) the moisture content of the molding sand, and 2) the type of binder used to serve as a bonding agent between sand grains. The variation or the first factor is restricted to the useable range for each sand mixture tested, which was determined by preliminary moisture, permeability, and green compressive strength tests on the mixtures. The variation of the second factor is limited to only three sand samples, containing, either singly or in combination, only two types of clay binder.

It is the author's hope that in addition to the technical information gained, this thesis may also serve to further promote the foundry program at the School or Mines and Metallurgy of the University of Missouri and serve to encourage more research at the school directly related to the foundry field.

The conclusions of this thesis, though perhaps lacking in absolute values for heat transfer rates, should serve as a good comparative guide to the properties that may be expected in similar or closely related sand mixes"--Introduction, pages 1-2.
