Embodiment Construction

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] attached Figure 1-2 Shown is the general configuration of the invention.

[0048] attached Figure 3-5 Shown is the gate valve configuration.

[0049] The slideway 46 of the door valve 1 is inserted or pulled out the joint plate 57, the joint plate 57 has a ball socket movable inlaid with the ball head of the door pipe 51 to connect the door pipe 51, a section of the door pipe 51 is connected in the transfer tank 7, the slideway of the door valve 1 Two oil cylinders 50 are arranged at both ends of 46, and the two oil cylinders 50 push the joint plate 57 and a blind plate 48 in opposite directions, push the joint plate 57 to move to the center of the slideway 46, and the pipe hole of the joint plate 57 and the hole of the gate valve 1 pass through the gate valve 1 to open. The oil cylinder 50 pushes the blind plate 48, and t...

Abstract

The invention discloses a bottom protrusion of a heat-insulation furnace. The bottom protrusion comprises a door valve (1), a door (2), a pressure arm (3), a chamber (4), a heat accumulator (5), protrusions (6) and a transfer tank (7). The bottom protrusion has the advantages that the door valve (1) is communicated with a pipeline of the transfer tank (7) to deliver molten aluminum into the furnace, argon pressure protective die filling casting effects can be realized, the chamber (4) is communicated with the heat accumulator (5) to recycle exhaust heat, the protrusions (6) are arranged at the bottom of the chamber (4), electricity can be saved, molten aluminum surfaces are low in temperature, protrusion covers (37) of the protrusions (6) wrap protrusion cores (39) and are buried in masonry bodies, annular or Archimedes-helix-shaped electric heating elements (38) are embedded in the protrusion cores (39) wrapped by the protrusion covers (37) and are connected with conductors (40), the conductors (40) penetrate the protrusion cores (39) to be communicated with high-temperature electric plugs (9), the electric plugs (9) are inserted into high-temperature power sockets (42), and power-frequency or intermediate-frequency currents for work can be provided; oxidizing slag can be prevented under inert gas shield conditions.

Description

technical field [0001] The invention relates to an aluminum melting and casting aluminum furnace, especially a casting aluminum holding furnace. Background technique [0002] In the existing hub casting holding furnace, due to the high temperature of pressure relief and exhaust, the general-purpose reversing valve cannot adapt to the use of expensive inert gas recycling and reuse. Therefore, 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. In fact, it is not the case. The heat carried by the pressure relief gas is heated by electricity. The discharge discards electric energy, which is undoubtedly a waste of cost. [0003] Of course, the biggest waste of cost in the furnace is not just discarding some hot air, but the biggest waste is that the electric heating element bakes and radiates the molten aluminum surface, which has low thermal efficiency, high temperature...
