Abstract

The quality of the finished casting is largely determined by the quality of the mold. Currently, there are a large number of variations in the composition of CHM (cold hardening mixes), differing both in the nature of the main component and in the nature and ratio of binders and other technological additives. As cleaning dust has a very developed surface due to technological reasons. According to various estimates, the specific surface area of gas cleaning dust is from 8, 000 cm²/g and higher. In order to verify this assumption, studies were conducted on the effect of the composition of the mixture using SCF (sand-clay forms), on some of its properties. In conclusion, the conducted studies have shown that in order to ensure the maximum performance of the technological properties of CHM, the optimal content of SCF in the mixture should be 2.0 - 10.0 wt.% in the ratio with orthophosphoric acid is not higher than 1.25.
