Abstract

This research was aimed at developing economizer on aluminum crucible furnace to improve the furnace’s performance. The research implements a Research and Development method. The economizer effects was determined from the performance test. The furnace were being tested with and without economizer at the same process condition. The developed furnace exhaust have the same diameter with the gas burner inlet. The exhaust was extended and curved to serve as an economizer. Aluminum of 11.78 kg can be melted with the economizer effects in 60 minutes, and only required 2.6 kg of LPG, whereas without economizer it required 3.1 kg LPG in 80 minutes for the same amounts of Aluminum. Penelitian ini bertujuan menambahkan economizer pada tungku pelebur aluminium untuk memperbaiki performa tungku. Metode Research and Development diterapkan untuk pengembangan tungku. Efek penggunaan economizer ditentukan dari uji kinerja. Tungku diuji coba tanpa dan dengan economizer pada kondisi proses yang sama. Saluran buang pada tungku berdiameter sama dengan saluran masuk. Saluran dibuat memanjang dan berbelok berfungsi sebagai economizer. Aluminium 11,78 kg dapat dicairkan memakai economizer dalam 60 menit dan membutuhkan 2,6 kg gas LPG, sedang tanpa economizer membutuhkan 3,1 kg gas LPG dan waktu 80 menit.

Abstract

The aerofoils are used to get the lifting force on the design of plane’s wings. The lifting force is caused by difference air velocity on upper and lower aerofoil which the magnitude depend on attack angle of aerofoil and air velocity exist surrounding. This experiment aims to show the force vector (pressure distribute) on the aerofoil. The aerofoil is attached by air with konstant velocity. The research procedure is done by change the attack angle of aerofoil on five formation. The surface of aerofoil is connected with pressure gage which disperse at 11 point of measurement. The result shows that magnitude of force vector is depended on attack angle of aerofoil. Increasing angle of aerofoil until boundary angle will be followed by increasing air velocity on the point of measurement and finally increase force vector. Upper boundary angle will be followed by decreasing air velocity and finally decrease force vector.Aerofoil digunakan untuk mendapatkan gaya angkat pada desain sayap pesawat. Gaya angkat disebabkan oleh perbedaan kecepatan udara pada aerofoil atas dan bawah yang besarnya tergantung pada sudut serang aerofoil dan kecepatan udara yang ada disekitarnya. Eksperimen ini bertujuan untuk menampilkan vektor gaya (distribusi tekanan) pada aerofoil. Aerofoil dilekatkan pada udara dengan kecepatan konstan. Prosedur penelitian dilakukan dengan cara mengubah sudut serang aerofoil pada lima formasi. Permukaan aerofoil dihubungkan dengan alat ukur tekanan yang tersebar pada 11 titik pengukuran. Hasil menunjukkan bahwa besarnya vektor gaya bergantung pada sudut serang aerofoil. Sudut aerofoil yang meningkat hingga sudut batas akan diikuti dengan peningkatan kecepatan udara pada titik pengukuran dan akhirnya meningkatkan vektor gaya. Sudut batas atas akan diikuti oleh penurunan kecepatan udara pada titik pengukuran dan akhirnya menurunkan vektor gaya.

Abstract

This research is aimed to study the characteristics of cast grinding balls produced by CV Baja Ellips Ceper, Klaten. The samples were taken from three tapping. One group was quenched in water while the other was not. The studied characteristics comprised of chemical composition, microstructure, hardness and wear. The result shows that the grinding balls have the chemical composition of medium-strength cast iron. However, the microstructure shows cementite and pearlite that indicates the structure of a white cast iron. The hardness of quenched and unquenched grinding balls are 60 HRC and 57 HRC, respectively. The hardness is consistent from the edges to the middle of the grinding balls. The specific wear of quenched grinding balls and unquenched grinding balls is 3.32963 x 10-06 mm2/kg and 5.032 x 10-06 mm2/kg, respectivelyPenelitian ini bertujuan untuk mengetahui karakteristik grinding balls produksi CV Baja Ellips Ceper Klaten yang dibuat dengan menggunakan proses pengecoran.
