Brief Analysis on the Advantages of Fused Ceramic Sand 2

Technological advantages of Fused Ceramic Sand for foundry

(1) Nearly spherical particles, smooth surface - low binder consumption, low gas generation, good fluidity, good filling, and good collapsibility after pouring;

(2) Low thermal expansion rate - the expansion rate of fused ceramic sand after heating is 1/5 of that of silica sand and 1/2 of that of chromite sand. The castings produced have high dimensional accuracy, few veins and cracks, and high yield of castings;

(3) Good crushing resistance - Fused ceramic sand has compact material, high compressive strength and low repeated crushing rate, which greatly improves the recycling rate of core sand, reduces the discharge of waste sand, and is conducive to environmental protection;

(4) High fire resistance - reduce sand sticking;

(5) The bulk density of Fused ceramic sand is relatively small - the bulk density of Fused ceramic sand is about 2 g/cm3, which is less than 2.5 ~ 2.9 g/cm3 of chromite sand. The sand core made is lighter, easy to handle, and can reduce the use of core sand;

(6) Good applicability to binder - the main component of Fused ceramic sand is alzo3, the pH is neutral, and the hardening binder of acidic and alkaline materials can be used;

(7) The price is relatively cheap - the price of fused ceramic sand is about 1/3 of that of wrong sand and 1/2 of that of chromite ore. Although it is much higher than silica sand, if equipped with appropriate regeneration equipment, the comprehensive cost of comprehensive accounting is lower than silica sand, that is, it has high performance price ratio.
