Abstract
The purpose of this research is to make and know the working system of krusibel furnace which is gas-fueled. Testing of crucible furnaces is done by means of aluminum smelting. The melting result is poured into the red sand mold. For pour casting height with variation 25 cm and 50 cm. The crucible furnace bedding starts from components comprising: The furnace is made with 85cm tall brick with an outer diameter of 75cm and a thickness of 20cm. The combustion pipe uses a 9cm diameter and 125cm diameter pipe, then welded with 1cm diameter pipe for gas entry, and blower placement at the end of the pipe. Heat pipe made of galvanized iron pipe diameter 2.5cm and 2m long as much as two pieces, weld with iron pipe diameter 9cm and length 12cm. drum as a place of gas and water with a diameter of 57cm, height 43cm, on the side is given a hole 2 parts to connect the heating pipe. In this study observation of temperature changes in the furnace every 5 minutes and fuel consumption. Tests performed to test the casting result are depreciation test, porosity observation, chemical test, brinell hardness test, and micro photo test (ASTM standard E 3). From the test results can be concluded that the highest temperature 790oC. To meleburkan 10 kg of aluminum into liquid diperluhkan time 30 minutes, with fuel consumption 9 kg LPG gas (3 tubes size 3 kg). The value of pouring distance of 25 cm is 5.691% for cylindrical specimens, and 3.864% for beams. While the depreciation value of casting distance 50 cm greater than the casting distance of 25 cm, ie 6.842% for cylindrical products, 5.329% in the form of blocks. The results of hardness testing, the value of HB to two sepesimen less than 70.00 kg / mm2. The chemical composition found in Alumunium (Al) 88.33% as the main material, and Silicon (Si) 7.01%, so that the existing elements include aluminum alloy silicon (Al-Si).
