Rancang Bangun Dapur Crussible dengan Kapasitas 6 Kg Berbahan Bakar Gas LPG

Abstract

Metal Casting is a manufacturing process that uses molten metal and molds to produce shapes that are close to the final geometric shape of the finished product. In the process of decomposing aluminum, a smelting furnace is needed using a smelting furnace where the raw materials and the type of furnace to be used must be adjusted to the material to be smelted. The choice of smelting furnace to be used to smelt metal must be in accordance with the raw material to be smelted. , knowing the use of fuel used. The type of kitchen used is a Crussible type smelter using kowi from graphite material where the source of fire comes from LPG gas. Maximum capacity of smelting is 6 kg. Kitchen walls use fire-resistant cement type SK-34 and fire-resistant bricks SK-34. The time to melt 6 kg aluminum in a smelting furnace using insulation is 50 minutes and is also more environmentally friendly with room temperature 36°C and maximum combustion temperature is 43°C. good heat absorption on the walls and insulation. The amount of fuel needed to melt 6 kg of aluminum in the smelting furnace is 0.11 kg
