FIELD: casting processes and equipment. ^ SUBSTANCE: cooling liquid contains aluminum and alloying elements such as copper and silicon. Components are taken at next relation, mass. %: copper, 25.6 - 27.8; silicon, 5.1 - 5.4; aluminum, 69.3 - 66.8. Presence of silicon provides enhanced fluidity and lowered viscosity of alloy. Silicon and copper have high heat conductivity, heat capacity and density providing increased convection cooling. ^ EFFECT: enhanced quality, improved technical and operational properties of castings. ^ 3 tbl, 1 ex |
