Abstract

A number of technologies is developed that substitute simple metal cores in the high-pressure casting technology. Soluble cores, namely

on the salt basis, represent the highest prospect. The contribution gives the results of the production of salt cores by high-pressure

squeezing and shooting with using a binder. Special attention is paid to the shape of NaCl salt crystals with additives and the influence on

strength properties of cores. A technology of bonding the salt cores is developing. Salinity of circulating water is studied and it is checked

with the aid of electrical conductance.
