This thesis is to study the influence of sectional shape of molten metal pour Rails affecting the mechanical properties and microstructures of metals, aluminium alloy. In experiments to make forging A356 aluminium alloy at a temperature of 800 degrees Celsius grades with electric ovens, coil resistance and pour the molten metal temperature of 720° c. By a permanent and craggy pour molten metal flow through the chute at a sectional shape consists of a half-circle cut shapes. Cut a triangle shape. Sectional shape trapezoid and rectangular shaped cross section length * 400 * mm * and * 35° tilt angle with the horizontal into a permanent formwork, respectively. Then remove the workpiece bending mechanical properties tensile stress safety standard on * ASTM E8. Hardness, hardness testing, using form partys Neil Verify the structure and find the average grain size by counting linear intersection.
