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 a big waste.
So if you melt fast, you will save more propane cost. Package includes all of items in my 1st photo, including crucible, casting mold, tongs, lifting and pouring tongs 2 in 1, gloves, fire brick, hose & clamps, instruction manual. Furnace body is made of stainless steel(1mm thick), no need painting, highly resistant to corrosion, superior strength and durability;Can bear the weight of one adult. Dual gas burners are made of stainless steel, each burner is around 100,000 BTU, fast melting can save 50% time and 20% gas cost ; 3. Furnace Outside Dimensions : 12" diameter x 15" height (30cm x 37cm); 4.
Furnace 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. Two crucibles: 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. Lifting and pouring 2 in 1 tongs, safe and easy way to handle molten metals. It is made from heavy duty steel.It has a 6 inch inner diameter ring can hold 10 or 16 kg graphite crucible. 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). Fast melting can save 50% time and 20% gas cost ; 3. 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.
