Abstract

"This investigation determined some of the induction heating characteristics of powdered magnetite, iron and ferrosilicon susceptor dispersed in silica sand which had been coated with thermosetting resin. The powdered susceptor particles in the mixture were heated by the field of an induction coil, consequently heating the resin coated sand and bonding the sand grains together.

It was found that the type, relative amount,and particle size of the susceptor were important variables to be considered in the induction heating characteristics. Hysteresis losses in the susceptor particles, which are a function of the coil current, frequency, and permeability, appear to be the primary cause of heating.

In addition, the effect of the susceptor particles on the strength of resin bonded sand was determined. The decrease in strength was found to be dependent on the number and size of the susceptor particles. Coating the susceptor particles with resin was determined to be effective in increasing the strength"--Abstract, page ii.
