  • High Temperature Properties of Molding Sand Bonded with Aluminium Phosphate

抄録

  To make a permanent sand mold usable for repeated usage, a study has been carried out on a sand mold bonded with aluminium phosphate and magnesium oxide. The mold thus prepared was durable enough to be used more than 20 times, its compression strength being above 10 kg/cm2. </br>  The rate of hardening could be controlled by varying the amount of adding magnesium oxide to the mold. Various sands such as olivine sand, chromite sand and zircon sand were employed, but irrespective of the kind of sand the compression strength was not lowered after a heating repetition of 20 times. Further it was found that the repetition of heating had no influence upon the surface condition of thd permanent mold. When the mold was heated, the compression strength was maintained constant up to 800°C but decreased at higher temperatures, espesially because of softening of bonding material above 1,000°C.
