Embodiment 1

[0071] Step 1. Bury the casting mold into a sand box, then push the sand box into a heating furnace and heat it to 1100°C for 4 hours;

[0072] Step 2. Open the furnace door, pull out the sand box embedded with the casting mold after the completion of step 1 out of the heating furnace, and place it on the casting mold base of the casting furnace with a plunger;

[0073] Step 3. Open the furnace cover, tilt the melting crucible at an angle of 45 degrees, push 50 kg of master alloy for melting and casting into the crucible along the mouth of the crucible, and at the same time add 10 grams of deoxidized carbon into the crucible, and then reset the crucible;

[0074] Step 4. The infrared temperature measurement and the galvanic temperature measurement response are normal, replace the blackened lens of the peephole, wipe the vacuum sealing surfaces, and then close the furnace cover and furnace door;

[0075] Step 5. Turn on the cooling water system, the inner cooling water pressure...

Abstract

The invention discloses a casting furnace capable of utilizing non-synchronous bending for obtaining liquid deep undercooling. The casting furnace comprises a constant magnetic field coil which is located in the casting furnace, after direct-current power is applied, a static magnetic field is generated, a casting mold is placed in the static magnetic field. Meanwhile, the invention provides a usemethod of the casting furnace capable of utilizing non-synchronous bending for obtaining liquid deep undercooling. A smelting pot is provided with an induction coil exerting an alternating magnetic field and exerting the static magnetic field at the same time or independently, the static magnetic field strength in the area, close to the 1 / 2 position of the smelting pot, in the induction coil canreach 1 Tesla or above. On the casting central portion, that is, the metal liquid solidified casting center portion, the highest static magnetic field strength can reach 1 Tesla or above. The furnaceis not suitable for magnetic materials and also suitable for the non-magnetic materials.

Description

technical field [0001] The invention relates to the technical field of special casting equipment, in particular to a casting furnace for obtaining liquid deep and supercooling by asynchronous bending and a method of using the same. Background technique [0002] Achieving deep subcooling in a large volume of liquid has always been a dream of those engaged in special casting. The application number is 201110430497.7, and the title of the invention is a fully-filled casting method below the melting point, which discloses a method for suppressing the precipitation of solids in a liquid by using a low-frequency, low-power alternating magnetic field. However, the invention can make the liquid supercooled. The ability of the liquid is very limited, because in order to enhance the ability of the liquid to supercool, it is necessary to increase the strength of the magnetic field that suppresses the precipitation of the solid, but the enhancement of the magnetic field will be accompan...
