Abstract

The invention discloses a bottom plate of a regenerative furnace and relates to an aluminum casting furnace. The bottom plate comprises a gate valve (1), a door (2), a pressure arm (3), a hearth chamber (4), a heat accumulator (5), a plate body (6) and a transfer tank (7). The hearth chamber (4) is communicated with the heat accumulator (5) and recycles discharge heat energy to save power. The gate valve (1) is communicated with the transfer tank (7) and conveys molten aluminum into the furnace in a totally sealed manner through a pipeline, argon shielding can be performed, oxidization is avoided, and slagging off is avoided; the plate body (6) is arranged on the lower portion of a liquid-rising tube in the center of the hearth chamber (4), an electric element (38) in the plate body (6) is formed by carbon and spiral or Archimedean spiral, the electric element (38) is communicated with an electric conductor (40), the electric conductor (40) is communicated with a power supply source to convey power frequency or medium-high frequency currents, and current frequency is 50-5000Hz.

Description

technical field [0001] The invention relates to a metallurgical melting and casting aluminum furnace, in particular to a casting aluminum holding furnace. Background technique [0002] For hub casting holding furnaces, the temperature of pressure relief and exhaust gas is generally equivalent to the furnace temperature of 700-800°C. At present, compressed air is generally used to pressurize the liquid casting mold and discharge it after use. There seems to be no "cost" for air discharge and disposal, but it is not the case. The heat carried by the pressure relief gas is electric heat energy, and discarding hot air is equivalent to discarding electric energy, which is undoubtedly a waste of cost. [0003] Of course, at present, the most wasteful cost of the holding furnace is not only the discarding of some hot air, but the biggest waste is that the electric heating element bakes and radiates the aluminum liquid surface, the thermal efficiency is low, the aluminum liquid surf...
