Round speedy energy conservation Al. melting furnace
Round speedy energy conservation Al. melting furnace
1, Service range：
Industrial aluminum materials, building aluminum materials series profile, hot rolled plate, sheet roll casting, conducting aluminum billet, Al-Ti-B rod (refining agent/flux), aluminum ingot alloy, pressure casting.
2, product main acteristics：
˙energy conservation, faster melting rate
Raw material will absorb heat high-temperature smoke in the shaft
Smoke exhausting temperature≤150℃，high heat efficiency
˙Low burning damage
No direct contact between flame raw material
˙No partial over-temperature
Strong furnace smoke recycling, uniform furnace temperature
˙high burning efficiency, fast temperature rising rate
As furnace enters into temperature rising holding stage, air preheater will be able to make efficient use of waste heat smokes.
˙Low temperature melting furnace shells
Reserved air-gap designed for furnace shell
˙Low labor intensity furnace temperature fluctuation.
Charging form furnace roof, ging will not delay anytime of melting.
˙Adopting high-efficiency energy conservation burner.
