How to choose the aluminum shell furnace and steel shell furnace of the induction melting furnace?

The aluminum shell furnace body is inexpensive, easy to maintain, and convenient to observe. The disadvantage is low efficiency and no shielding of electromagnetic radiation.

The shell furnace body is welded with high-quality steel structure, with a leak-proof furnace alarm device, and the inductor is enclosed by a magnetic yoke, covering an area of more than 65%. Because of its low magnetic leakage and high efficiency, it saves nearly 5% of energy consumption compared to aluminum shell furnaces.
