INTRODUCTION<\/strong><\/p>\n

Earlier researches have showed the strength, hardness and other mechanical properties, by showing tensile test, hardness test, and other tests. To prove that tests, it\u2019s necessary to explain specific design of their stir. A proper shape with desired parameters of stirring should be satisfy the mixing to get desired chemical compositions by mixing reinforcements in base Aluminium. In this review paper we are showing comparison among 3 different types of stir with different \u2013 different parameters.<\/p>\n

There are 3 different shapes of stir as follows:<\/p>\n

    \n
  1. Bevel shape stir<\/li>\n
  2. Spur shape stir<\/li>\n
  3. Helical shape stir<\/li>\n<\/ol>\n

    All these stirs are fabricated of graphite and bevel and spur shapes prepared by vertical milling machine and helical shape stir prepared by horizontal milling machine. All the stirs were using on 400 -500 rpm and 10 \u2013 15 minutes.<\/p>\n

    \u00a0\"\"<\/strong><\/p>\n

    \"\"<\/p>\n

    In this stir design we designed 12 teeth on gear. Due to low depth and size of teeth it was unable to perform uniform distribution during mixing of base metal (molten Aluminium) and reinforcements. On the behalf of size of cylindrical shaft of graphite the numbers of teeth were not appropriate to perform uniform distribution. During mixing of metals the fewer amounts molten metal rotates with the stir which gives bad results of distribution.<\/p>\n

    \"\"<\/p>\n

    \"\"<\/p>\n

    In this stir design we designed 24 teeth on gear. Due to straight shape of teeth pervert the inlet and outlet of fluid on the stir. Due to less depth and size of teeth it was unable to perform uniform distribution during mixing of base metal (molten Aluminium) and reinforcements. On the behalf of size of cylindrical shaft of graphite the number of teeth was not appropriate to perform uniform distribution. During mixing of metals the fewer amounts molten metal rotates with the stir which gives bad results of distribution.<\/p>\n

    \"\"<\/p>\n

    In this stir design we designed 6 teeth on gear. Due to sufficient depth and size of teeth it performs uniform distribution during mixing of base metal (molten Aluminium) and reinforcements. We prepared helical cut on the stir on the angle of 25\u00ba. Angular shaped teeth stirred fluid during mixing by taking similar area in the fluid. Angular motion of fluid by the stir gave better results in stirring.<\/p>\n

    By mixing 5% reinforcement in the base metal during stirring for 15 minutes on 400 rpm helical shape stir mixed them uniformly. By using chemical composition test, test showing that reinforcement mixed in base metal 4.76% uniform.<\/p>\n

    Hence we can say that helical shape stir can give better result in stir casting process.<\/p>\n

    CONCLUSION<\/strong><\/p>\n

    By performed practical work with all these 3 types of stir with different – different parameters, we concluded that on the stir teeth size, thickness of teeth, tooth depth, and space between 2 teeth takes important place in stirring.\u00a0Therefore we used 6 teeth on helical type stir by rotate it on 400-500 rpm. By using helical stir we performed uniform distribution.<\/p>\n
