Spray forming cooling system and method for decreasing temperature of ingot blank through spray forming cooling system

Abstract

The invention discloses a spray forming cooling system and a method for decreasing the temperature of an ingot blank through the spray forming cooling system. The system comprises a spray forming device and a cooling system, the cooling system comprises a heat absorption structure, a cooling device, a circulation power pump, heat conduction media and a heat conduction medium conveying pipeline which is sequentially connected with the heat absorption structure, the cooling device and the circulation power pump to form a heat condition loop. The heat absorption structure is located inside an atomization chamber of the spray forming device and used for cooling the ingot blank or a tray, and the cooling device is located outside the atomization chamber of the spray forming device and used for cooling the heat conduction media of which the temperature is increased because heat of the atomization chamber is absorbed. The heat conduction media flow inside the heat conduction loop in a circulation mode under the action of the circulation power pump to absorb heat in the atomization chamber and perform cooling inside the cooling device. The spray forming cooling system has the advantage that the heat conduction media are adopted for directly cooling the ingot blank or the tray, so that the ingot blank of which the performance meets the requirement is obtained.

Description

technical field [0001] The invention relates to the field of metal material ingot spray forming, in particular to a spray forming cooling system and a method for reducing the temperature of an ingot by using the system. Background technique [0002] The ingot spray forming technology is an advanced technology that makes the liquid metal alloy form solid, semi-solid, liquid mist micro-particles deposited on the receiver to form an ingot under the action of inert gas. [0003] The atomization chamber structure of the ingot spray forming in the prior art is as follows: figure 1 As shown, it includes a leak bag, a metal liquid column, an atomizer, an air inlet, an ingot, a tray, a rotating shaft, a moving shaft, an air outlet, and an atomizing box. During work, the inert gas for atomizing the metal is sprayed into the atomization chamber through the atomizer through the air inlet. The liquid column is atomized into tiny solid, semi-solid or liquid fine metal particles by the i...

AI Technical Summary

Problems solved by technology

During the entire spray forming process, the condensation of the metal liquid column releases a large amount of heat, part of which is discharged from the air outlet installed on the atomization box, but the other part of the heat is gathered in the atomization chamber, causing the temperature of the atomization chamber to rise rapidly. High, the atomization room temperature is too high, it will affect the cooling rate and the temperature of the ingot itself, the cooling rate of the ingot is too slow, the crystals constituting the ingot are thick, and its mechanical properties and machining properties are greatly affected. It can even result in organizations that don't get what they need

Therefore, it is necessary to find a way to cool the spray chamber, and the existing equipment does not have a cooling system
