Gas Metal Melting Furnace is used to melt brass, gold, silver, copper, aluminum, zinc, tin and other metals with melting points below 1450 ° C(2642 ° F). Suitable for most fuels, liquefied gas, LPG, propane, etc. Many other people's single burner furnace or double burners at one side furnace have a problem, the flame can only heat one side of crucible strongly, especially if you use a big size crucible, the flame can only reach to 1/3 or 1/2 wall of the crucible, the opposite side has no flame. So we often saw that some part of metal in crucible has been melted, but some other part is not yet.
It means you need longer time and more gas to melt whole pot of metal, my dual burners have solved this problem by heating 2 sides of crucible at the same time, it can save 50% time and 20% gas cost. As we know, 40%--70% gas energy is actually escaping in heating process, that is big waste. So if you melt fast, you save more propane cost. Package includes all of items in my 1st photo, including crucible, casting mold, tongs, gloves, fire brick, hose & clamps, instruction manual.
Furnace body is made of steel(1.5mm thick), superior strength and durability; 2. Dual gas burners are made of steel, each burner is around 100,000 BTU, fast melting can save 50% time and 20% gas cost ; 3.
Outside Dimensions : 12" diameter x 15" height (30cm x 37cm); 4. Inner Dimensions: 8" diameter x 10"Height (20cm x 24cm); 5. Adjustable high pressure gas regulator with gauge from 0--30 psi, 5 ft (1.5m) long hose, USA certificated; 6. 16 kg crucible can load 16 kg brass or 4.8 kg aluminum or 19 kg silver.6 kg crucible can load 6 kg brass or 1.8 kg aluminum or 7 kg silver ; 7. Graphite casting Mold: 113 ML capacity, size is 1256040 mm, can melt 2 kg gold, 1.2 kg silver, 1kg copper. Two carbon graphite mixing stirring rods :one 8X300mm long and the other 15X300mm long;Carbon rods are used to stir precious metals, scrap while melting.
Graphite rod is also used to remove any impurities on the surface of the molten metal. Furnace body and lid are fully lined with 2 inch of ceramic fiber insulation. Furnace floor lined with 3 inch of ceramic insulation and firebrick.
You only need a propane gas bottle/tank (like 20,30 or 50 LB). Dual burner can save 50% time and 20% gas cost. The air choke on our burner can control the air and flame at different gas pressure.
You also can use only one burner by shut off the valve, and block one hole on furnace body with ceramic wool. Do not use it to melt iron, that will shorten the life of the furnace.
Graphite crucible is consumable, you can change a new one according to your requirement. Use safety goggles, mask as well as gloves while casting metals. The ceramic insulation blanket is not asbestos.Asbestos has been forbidden many years ago. We have 3 warehouse in East, Central and West of USA. So you can receive it in 2--5 days.
