Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] attached Figure 1-2 Shown is the general structure of the present invention.

[0037] attached Figure 3-5 Shown is the furnace cavity masonry and furnace heat storage structure.

[0038] The furnace 1 has a chamber 42 in the shape of a water drop arc, two symmetrical large arcs 32 chamber 42 vertical walls and a small arc 31 vertical wall are cut into shape, and the vertical wall and bottom of the chamber 42 are formed by more than three layers The inner lining layer is a ceramic masonry layer, and the other is an insulating masonry layer. Aluminum foil is attached to the surface of the insulating masonry. There are 5 layers of powder formed between the masonry layer and the masonry layer. The layer is filled with fine powder 5, the fine powder 5 is ≤320 mesh mineral composition, the specific gravity is ≥2.7g / cm, the ≤320 me...

Abstract

The invention discloses a bottom block of a regenerative furnace and relates to kilns and furnaces for melting and casting aluminum. The bottom block is provided with a body and comprises a door (1), a hearth chamber (2), a heat accumulator (3) and a heat block (4). An electric heating body (36) is arranged in the right-angle cover (9) of the body of the heat block (4). A plug (39) is connected to the lower end of the heating body (36) and inserted into a socket (38). The socket (38) is communicated with a wire (40) which is connected with a power distribution box (14). The power distribution box (14) is communicated with a power supply. The vertical section of the right-angle cover (9) is inserted into the bottom of the hearth chamber (2). Sealing (37) is arranged between the vertical section of the right-angle cover (9) and the bottom of the hearth chamber (2). The heat accumulator (3) is formed by rolling a heat accumulation piece (34). Radiating air channels (33) are formed in the upper surface and the lower surface of the heat accumulator (3), and air flow passes the gaps, dispersed in the heat accumulation piece (34), of the air channels (33).

Description

technical field [0001] The present invention relates to cast aluminum, in particular to cast aluminum furnaces. 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 equal 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 hot gas, 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 surface temperature is high, the aluminum liquid is oxidi...
