Question

Transcribed Image Text:Question 3 The component shown in Figure 3 is casted from grey cast iron, with a density of 7150 kg/m and a viscosity of 0.014 Ns/m², at the casting temperature of the material. The casted component has a volume of 0.0022 m3 and is manufactured through the sand casting process. During the casting process the metal level in the pouring basin is 300 mm above the metal level in the mould. The runner have a circular profile of Ø 12 mm. Ø 300,0 Ø 200,0 Ø100,0. 1.6/ R5 R5 60 H7 SECTION A-A Figure 3: Component to be casted 3.1 Calculate the velocity and the flow rate of the metal into the mould. Is the flow turbulent or laminar? 3.2 If product shown in Figure 3 is to be casted in aluminium, which factors should be considered if the same pattern and mould configuration (shown in Figure 4 below used to cast the product from cast iron), is used to cast the product from aluminium? Cope Sprue Parting line Gate Drag Runner Figure 4: Mould configuration used to cast the component in grey cast iron (not to scale) 001
