FIELD: foundry, in particular refrigerating fluid. ^ SUBSTANCE: claimed fluid contains (mass %): copper 24.9-27.1 and tempers: silicium 6.0-7.0; iron 0.4-0.6; aluminum 68.7-65.3. Copper and silicium decrease fluid viscosity, increase castability and improve convective cooling. Iron in limits of its solubility in aluminum affords the ability to except dissolution of crystallizer steel bath. ^ EFFECT: casts of improved quality and performance. ^ 3 tbl, 1 ex |
