Paper Title:
Study on the Properties of Magnetization Modified Sodium Silicate Sand
  Abstract

Based on the magnetization technological parameters optimized of sodium silicate, the properties of modified sodium silicate sand with ester hardening have been systematically investigated. The results indicated that the bonded strength of sodium silicate treated in the magnetic field may be increased by 30%~40%, the minimum addition content of sodium silicate in mold sand may reduce to 2.5%, and thus it improves markedly the collapsibility of the sodium silicate bonded sand. The used time of modified sodium silicate sand increases to 25%, but the effect of magnetization of sodium silicate will be disappeared after 24 hours, and the magnetization decaying speed enhanced with increasing the modulus of sodium silicate. The magnetization modification has a good effect on the high modulus sodium silicate than the low modulus sodium silicate.
