Gas Metal Melting Furnace is used to melt copper, gold, silver, copper, aluminum, zinc, tin and other metals with melting points below 1300 ° C. Suitable for most fuels, liquefied gas, LPG, natural gas, propane, etc. Many other people's single burner furnace has a problem, the flame can only heat one side of crucible strongly, especially if you use a 10KG 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 burner 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, tong, 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 burner, each burner is around 100,000 BTU, fast melting can save 50% time and 20% gas cost ; 3.
Outside Dimensions : 10" diameter x 12" height (25cm x 30cm); 4. Inner Dimensions: 8" diameter x 7.6"Height (20cm x 19cm); 5. Adjustable high pressure gas regulator with gauge from 0--30 psi, 5 ft (1.5m) long hose, USA certificated; 6. Crucible can load 8 kg brass & 3.2 kg aluminum ; 7. Graphite casting Mold: 113 ML capacity, size is 1256040 mm, can melt 2 kg gold, 1.2 kg silver, 1kg copper.Furnace body is fully lined with 1 inch of ceramic fiber insulation and lid is 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. You also can use only one burner by shut off the valve, and block one hole on furnace body with my additional 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, it is not harm to health. Asbestos has been forbidden many years ago.
I don't think it is necessary to coat fire cement /refractory mortar or rigidizer on ceramic wool. PO Box is not accepted. We have 3 warehouse in East, Central and West of USA.
