Manufacturing of Aluminum Metal Smelting Furnaces with LPG Gas Fuel to Support Student Practicums

Abstrak

Work in aluminum metal casting includes several stages: preparation of raw materials, mold making, smelting process, the casting of castings, dismantling, cleaning, and inspection of castings. Students are ready to compete in the industrial world or entrepreneurship with these hands-on skills. To achieve this goal, the Polytechnic provides adequate learning and practice experiences to form professional abilities in science and technology. Competence in one field, for example, in material knowledge (metal casting). Because the tools for the metal smelting process are not available yet, this research aims to design and manufacture an aluminum smelting furnace fueled by LPG gas, which can also be helpful and contribute to the process of making aluminum metal smelting furnaces. The test results show that the aluminum metal smelting furnace with LPG gas fuel and aluminum metal raw materials for motorcycle brake canvas can operate and work well. The need for LPG gas fuel to melt aluminum canvas motorcycle waste material is 0.6 to 1 kg. The temperature required to melt aluminum metal is 658 °C to 784 °bC with a melting time of 10 to 18 minutes. The maximum capacity that can be smelted raw materials is 1000 grams.
