【16KG Large Capacity Melting Furnace】The propane furnace inner size is 8" diameter x 10"Height (20cm x 24cm), which could contains large crucibles up to 16KG. Our metal smelting furnace kit equipped 2 crucibles for you. 16KG graphite crucibles can melt 16KG copper, 30KG gold, 4.8KG aluminum, 19KG silver; 6kg crucible can melt 6KG copper,11.2KG gold, 1.8KG aluminum, 7KG silver. The accompanied ingot mold are perfect for casting mould for copper gold silver aluminum brass.
【Double Forge Burners Furnace】LSMIITTH metal smelter take special design with double forge burners on both sides of furnace. Compared to the single burner or the double burner all in one side, the flame would be more evenly distributed. The output of each burner is 100,000 BTU. Fast melting can save 50% of the time and 20% of the gas cost. Our 2 burners designed with air choke to adjust the oxygen intake.
【High Temperature Resistance】High pressure gas melting furnace can withstand high temperatures of 2642°F (1450° C) , our graphite crucibles could withstand 3272°F(1800℃), which means that you could use this foundry to melt copper, gold, silver, brass, aluminum, zinc, tin, glass and other metals with melting points below 2372℉(1300℃). Very suitable for home forging, jewelry processing, metal casting. Be attention: it can not melt steel, iron.
【Safe and Proffesional】The aluminum melting furnace is made of steel, thinness is 1.5mm, superior strength and durable. The full body and lid are fully lined with 2 inch of ceramic fiber insulation. Highly heat resistant. Safe enough for smelting. The burner gas hose with regulator input is QQC type, output is 5/8", which can hook up to American standard Propane Tank directly. Maximum Output is 30PSI (CSA). You can control gas consumption by adjusting gas pressure easily.
【What You will Get】We are professional seller of smelters for metal full kit. We suggest melting for a MAX of 30 minutes at a time. If there is any problem, you could contact us directly. Package include: 1 propane smelting furnace, 2 graphite Crucibles(16KG&6KG), dual forge burners, 1.5m gas hose with regulator, 113ML ingot mold, 1 refractory firebrick, 1 carbon stirring stickes (0.8X30cm), 40cm tongs, and other casting tools.

Product Description

LSMIITTH Propane Smelting Furnace Kit with Fundry Casting Tools

foundry furnace with casting tools for melting metal

LSMIITTH Propane Melting Furnace Kit help you fun for melting gold,silver,copper,aluminum,brass and making trinkets.

We are the first one to sell melting furnace with burners on both side, which ensures complete combustion of the metal in shortest time and save 20% gas consumption.

LSMIITH Metal Melting Furnace Temperature Resistance up To 2642°F (1450° C)

You could use LSMIITTH foundry furnace to melt copper, gold, silver, brass, aluminum, zinc, tin, glass and other metals with melting points below 2372℉(1300℃).

Please stop smelting every 30 minutes to reduce freezing and protect casting tools.

Preparation for Forging

1. Please pull the burner outward after the burner installed to the furnace, keep the burner head buried in the insulation, which could protect the burner heads and ensure the crucible can be placed in the furnace properly. Please check: burner head buried.jpg

2. Please make sure all the assembly are installed tightly, and keep there is no gas leak before melting. Liquid soap could test the gas leak.

3. Please use protective equipment, such as goggles or gloves, before casting.

4. Preheat the empty crucible and ingot mold at around 500℉ for 5 mins, making sure them absolutely dry before 1st use.

5. Prepare a high pressure Propane tank (like 20LB,30LB or 50LB ).

Start Melting with LSMIITTH Furnace

1. The metal furnace only suitable for high-pressure gas tanks, it is not suitable for natural gas.

2. If you use the full propane tank, adjust gas tank, regulator, and burner pressure from LOW pressure first. Adjust them slowly to find a best pressure setting.

3. Remember that set the regulator from 0psi to 3psi and to 5psi. Do not release too fast. Pressurize slowly.

4. The valve on your bottle may freeze if gas flow too fast. You should stop fire and reset again.

5. The small hole on the gas tip shouldn't be blocked, if blocked, it will cause uneven flames. Please check the image: small hole of gas tip.jpg

6. If the flame large and fast first and then get slow, it might be the regulator turn on the protection mode because of excessive airflow or air leak. Please use a wire to push the hole on the regulator end that connect with gas tank again. Please check the image: regulator.jpg

7. If it sounds like sputtering, and there is enough propane, your mixture is out of balance. You could adjust the air choke to adjust the amount of air and propane. Because the burner is auto air choke, you could use a tinfoil to adjust the air. Please check the picture: flashback arrestor.jpg

8. The Most Important: Stoping melting every 30 mins, which could reduce freezing and it could protect casting accessories to some extent.

Sturdy, well insulated, easy to assemble. As a beginner in the metal melting business, I would've liked to know beforehand that the ceramic fiber needs to be sealed to avoid health hazard to the lungs (silica particles are very dangerous). Still 5 star because I should've done my homework. For those who wonder, I'm starting this in 3 steps. 1. 2 coats of Cab-O-Sil as a rigidizer (don't bother buying premixed rigidizer, Cab-O-Sil is a lot cheaper). 2. 2-3 1/8th of an inch coats of satanite ( to get 1/4 to 3/8 of an inch total), then fire the furnace at low temp for ~45 sec then let it cool, repeat the firing at medium temp for a minute then let it cool, repeat again at high temp for 2 min and let it cool. And finally 3. A thin layer of ITC-100 (1/16 to 1/8 of an inch) and do the gradual firing and cooldown sequence again. Then you're good to go. This is what I'm doing, it's not the only viable option, I suggest that you do some research before starting and find what coating suits your forge best.The final coating of itc-100 isn't yet applied and it already burn hot enough to melt a piece of vintage cast iron weight that was making a gap in the door to cure the satanite.
