Abstract:

“Abstrak : Sejak semakin mahalnya harga miyak bumi, sebagian besar industri kecil pengecoran logam tidakdapat bertahan karena biaya produksi yang semakin tinggi. Oleh karena itu dicari bahan bakaralternatif yang dapat menggantikan minyak dan gas dengan aman dan murah. Indonesia kayaakan batubara yang dalam pasar domestik dijual dalam bentuk briket batubara kalori rendah,oleh karena itu dilakukan desain untuk membuat tungku dengan bahan bakar ini. Proses desaindilakukan dengan mulai menghitung kalor yang dibutuhkan untuk melebur lagam, dalam hal inilogam yang akan dilebur adalah kuningan (CuZn5). Selanjutnya dilakukan pemilihan materialrefraktori untuk tungku yang dapat meminimalisir heat loss. Desain tungku pengecoran inidilakukan dengan menggunakan Multichart Diagram untuk effisiensi 40 % dan kapasitas 150 kgkuningan. Hasil Uji coba pengecoran dilapangan ternyata effisiensi tungku adalah 42%, lamapeleburan 3,5 jam.Kata kunci: Tungku pengecoran kuningan, briket batubara kalori rendah, mulichart diagramAbstract : Since the increasingly price of oil fuel, mostly small foundry industry can not survive due to thehigher production costs. Therefore searching for alternative fuels that can replace oil and gas safelyand inexpensively is promoted. Indonesia is rich in coal. In domestic market is sold in the form oflow-grade coal briquettes, therefore, is carried out the design to make furnace from this fuel. Thedesign process is done by beginning to calculate the heat needed to melt this alloy, in this case themetal to be melted is brass (CuZn5). Furthermore, the material selection for refractory furnace tominimize heat loss. This casting is done by using Multichart Diagram for 40% efficiency andcapacity of 150 kg brass. The test results during experiment obtained that efficiency is 42% in 3.5hours.Keywords: Furnace casting brass, low grade coal briquettes, multichart diagram”
