This double burner furnace set including all of items in the main photo: Furnace body is made of stainless steel( 1mm thick), no need painting, highly resistant to corrosion, superior strength and durability; Double gas burner ,each is around 100,000 BTU ,fast melting can save 40% time and 20%–30% gas cost ; Outside Dimensions : 12″ Width x 15″Height (30cm x 38cm); Inner chamber Dimensions: 8″Width x 10″Height (20cm x 25cm); Adjustable high pressure gas regulator with gauge from 0–30 psi , 5 ft (1.5m) long hose,USA certificated; Melt pot size for 10 kg brass & 5 kg aluminum casting; Including 2 burners ,furnace, crucible(melt pot),casting mold, tong ,HP regulator with guage, Instruction Manual; Features: 【Work Efficiently】Propane melting furnace can be heated up to 2640 °F / 1450°C and can melt metals with a melting point below 2372F (1300 ℃). such as gold, sterling silver, copper,aluminum, zinc,brass, bronze, tin etc. Suitable for most fuels, liquefied gases, natural gas, propane, etc. Attention:Many other seller’s single burner furnace must take long time to melt metal , because one other side of crucible have not flame,my double burner furnace solved this problem by heating 2 sides of crucible, save 50% time and 20%–30% gas cost. 【Large Capacity】 crucible( melting pot ) can melt 10KG copper,20KG gold, 5KG aluminum,10KG silver. It is made of natural graphite with good thermal conductivity, which can withstand high temperature 2600F (2000 ℃). Graphite casting Mold: 113ML capacity, inner size is 125*60*40mm, can melt 2 kg gold, 1.2kg silver, 1kg copper. The brightness of the crucible is less than 0.1%, ensuring that the metal purity will not be affected during metal refining. 【Durable Materials】Furnace body is made of stainless steel ,no need painting, highly resistant to corrosion, lightweight and strong enough to 160LB people standing (see my photo, I can stand on the body), superior strength and durability. 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 . (which can withstand high temperatures of 2600F (1425° C) , and is a replaceable inner wall material. Attention please: My furnace and forge only use high class Ceramic Fiber Insulation (needled thermal ceramic blanket), temperature grade is 2600F (1425° C) ,density is 8 lb/ft3 (128 kg/m3) . But some other competetor’s ceramic insulation is 2300F (1260° C) ,density is 6 lb/ft3 (96 kg/m3) ,their cost is only half of mine, cheap and short life. 【Safe and Easy】USA certificated adjustable high pressure gas regulator with gauge from 0–30 psi , 5 ft (1.5m) long hose. Can fit with USA, Canada, Australia propane tank. You can control gas consumption by adjusting gas pressure. Technical Support: 1. Can melt copper, aluminum, gold, silver, zinc and other metals with melting point below 2372F (1300 ℃). 2. After you use it, you cann’t cool it down quickly, you should cool it down naturally. Graphite crucible is consumable, you can change a new one according to your requirement. 3. Do not use it to melt iron, which will shorten the life of the furnace. 4. Before use, please bring high temperature gloves, high temperature mask and high temperature clothing. Prepare a bottle of fire extinguisher beside to prevent accidents. 6. I don’t provide fire-resistant cement(refractory), but you can buy 2–3 LB by yourself to protect ceramic wool for longer life. Precautions for use: 1. Use the site to ensure that it is open, ventilated, and free of flammable materials. 2. Keep the escape route clearly marked during emergencies. 3. Keep the fire extinguisher at hand. 4. Before using this product, please bring high temperature gloves, fire protection masks and other labor protection supplies. 5. The entire melting process requires someone to stare. 6. Prohibit overload smelting to prevent liquid metal from flowing out. 7. Be careful when the raw material is added during the melting process. 8. It is forbidden to melt iron, manganese and other metals with a melting point higher than 1400 ℃, otherwise the furnace wall will melt. 9. If it is used for a long time, the material of the inner wall of the furnace can be replaced. 10. Do not look directly at the degree of melting during the melting process to prevent heat waves from damaging the body. Only by taking security measures. * Orders Shipping within 1 day with tracking number .
