TOVP: Metal Casting (Album with photos) TOVP: Metal Casting (Album with photos)
\nSadbhuja Das: Last week in our GRC Factory we experimented with metal casting into a sand mold. We made our fresh Copper based alloy with Nickel, Silicone, Bismuth, Zinc and Aluminum. This alloy creates a non- leaded yellow brass. Our experimental melting furnace runs on regular kitchen gas and it has a maximum temperature of 1,600\u00b0C \/ 2,912\u00b0F. Volcanic lava is a liquid usually at temperatures from 700 to 1,200 \u00b0C, so this is some courageous work we are doing in service of the TOVP!
\nThis fire is strong enough to melt all of non-ferrous and most of ferrous alloys. This is the process as follows. Melting 7 kilograms of brass in a silicon-carbide crucible takes 15-20 minutes. Then we pour the metal into the pre-made sodium-silicate sand mold cured with carbon dioxide gas. The casting solidifies within a couple of minutes. Then the model is washed by a high-pressure water jet, polished, and then fine tuned. The images included show this experimental casting process.
