The slow heating is to prevent the wet crucible from bursting due to sudden heating. (2) Heating and feeding: When the temperature continues to rise to 800 °C, take out the crucible from the furnace, carefully add the stirred charge into it, and cover the upper part of the charge with a small amount of borax. When the charge in the crucible is melted, stop the oil and stop the air, add part of the charge wrapped in paper, and continue heating. Charges can be added multiple times. (3) Melting: After the charge is added enough, it enters the full melting stage. Usually, a 20# crucible can melt 10-15 kg of gold mud at a time. It takes 1.5 hours to melt. Take it out, and quickly pour the melt into a squatting tank (a conical cast iron tank with a big mouth and a pointed bottom) to cool in layers, pour it out after condensation, and strike with a small hammer to separate the slag from the gold-silver alloy. (4) Ingot casting: After smelting, all gold nuggets are concentrated for ingot casting. Crucible smelting is mostly found in small mines, and is suitable for smelting gold placer, amalgam and gold-containing steel wool, and can also be used for smelting cyanide gold mud. testing center-01 Why Choose Us 1.Strong professional: Our company has thirty years producing experience in refractory products.
