| Abstract | ||
| In this research, we have designed and evaluated the solar furnace that used to melt metals by using paraboloid dish concentrator to focus solar radiation. The diameter and depth of dish are (1.6 m) and (0.2 m) respectively while the crucible made of graphite as a receiver where placed metals inside it .Two axes system has been used to track the movement of the sun manually. The highest temperature recorded inside the crucible was (534o C) . It was melting the materials of lead and zinc. Also studied the effect of wind speed and intensity of solar radiation on the melting process where he found that the melting time increases with increasing wind speed which cause the increasing in convection losses, and decrease with increasing the intensity of solar radiation | ||
