Embodiment Construction

[0015] Such as figure 1 and figure 2 A coreless air pressure heat preservation pouring furnace is shown, its structure includes a crucible 2, a furnace lining 3, a coil 5, a steel shell 13 and a sealed furnace cover 6, the crucible 2 is placed inside the furnace lining 3, and the left and right sides of the furnace lining 3 are respectively the feed flow Groove 8 and discharge launder 9; a siphon tube 4 is formed between the crucible 2 and the furnace lining 3, the coil 5 surrounds the outside of the furnace lining 3, the steel shell 13 is installed on the outside of the coil 5, and a gas inlet 7 is provided on the side of the crucible 2 . When working, the coil 5 generates a magnetic field by passing current to the coil 5, and the metal placed in the magnetic field will continue to heat up under the action of the induced eddy current, and at the same time, the pressurized gas is passed into the crucible 2 through the gas inlet 7 to increase the temperature ( Insulation) mo...

Abstract

The invention relates to a coreless air pressure thermal-insulating pouring furnace. The coreless air pressure thermal-insulating pouring furnace structurally comprises a crucible, a furnace lining, a coil, a steel shell and a sealing furnace cover, wherein the crucible is arranged inside the furnace lining; a feeding flow groove and a discharging flow groove are located at the left and right sides of the furnace lining respectively; a siphon is formed between the crucible and the furnace lining; the coil surrounds the outside of the furnace lining; the steel shell is mounted on the outer side of the coil; a gas inlet is also arranged at the lateral upper side of the crucible. The coreless air pressure thermal-insulating pouring furnace heats uniformly, ensures consistence of temperature of a feeding port, a discharge port and the inner part of the crucible, reduces molten slag, enables molten iron to be kept in a fluid state all the time, achieves the capabilities of slowing spheroidization degradation of iron ball and vermicular iron, and also has the advantages of being simple in structure, easy to manufacture, energy-saving, environment-friendly, practical and efficient.

Description

technical field [0001] The invention relates to a pouring furnace, in particular to a coreless air pressure heat preservation pouring furnace. technical background [0002] In the foundry production industry, due to the difference in scale and level, the pouring method and pouring equipment used in the molding production line of the sand box are greatly unbalanced in its structural form and development. [0003] The casting furnace in the prior art generally adopts cored heating, and the coil is installed at the bottom of the furnace. By energizing the coil, the coil generates a magnetic field, and the iron core placed in the magnetic field will continue to heat up under the action of the induced eddy current. The heat is transferred from bottom to top to the furnace lining, so as to complete the heating of the material; heating in this way has problems such as uneven heating and low heat utilization rate, so it is particularly important to design a coreless air pressure hea...
