Smelting furnace

Abstract

The invention discloses a smelting furnace, which can be used as an independent trial-produce smelting furnace and can also be used as a smelting furnace suitable for continuous cast extrusion production below 400kg / h by externally being connected with a traditional large-capacity smelting furnace. The smelting furnace comprises a furnace body with a heat preservation layer and a heat preservation cover on the furnace body. A heating chamber, a temporary storage chamber, a buffering chamber, a heat preservation chamber, a conveying passageway are arranged in an inner cavity of the furnace body, wherein the bottom of the buffering chamber and the heat preservation chamber are communicated with each other, and the conveying passageway is communicated with the temporary storage chamber and the buffering chamber. A plug-in stopper penetrating out the heat preservation cover is arranged in an inlet of the conveying passageway, namely a discharging port of the temporary storage chamber. Theheating chamber and the temporary storage chamber are connected through the discharging port, a discharging gate is arranged in the discharging port, a pouring port is arranged at the bottom of the heat preservation chamber, the stopper penetrating out the heat preservation cover is arranged in the pouring port, and a heating device is arranged in the heat preservation cover. An outer feeding port is arranged outside the temporary storage chamber, and a feeding gate is arranged in the outer feeding port. The smelting furnace is mainly used for cast extrusion trial-produce and continuous production of aluminum profiles.

Description

technical field [0001] The invention relates to a melting furnace used for melting, refining, heat preservation and casting of aluminum alloy and other metal materials. Background technique [0002] The melting furnace used for aluminum alloy casting production usually adopts heavy oil, diesel, gas, electric heating, etc., and the electric heating includes: electric heating wire, silicon carbide rod, etc. Those skilled in the art know that for a smelting furnace, the smaller its capacity, the more difficult it is to control the quality of the melt and the continuous casting flow of the melt. Therefore, the structure of the traditional smelting furnace is relatively simple, and usually only has a heating chamber. The furnace production line composed of the traditional smelting furnace can only adapt to the continuous production of casting and extrusion of aluminum alloy conductive rods above 800kg / h. Therefore, the traditional smelting furnace usually has a large capacity (g...

AI Technical Summary

Problems solved by technology

Therefore, the traditional smelting furnace usually has a large capacity (generally between 0.8 and 10 tons), and its application range is limited. It cannot adapt to the continuous production of casting and extrusion below 400kg / h; A separate trial production melting furnace is used
