Description

Technical Field

[0001] The invention relates to the technical field of titanium alloys, in particular to a cooling device and a method for accelerating the smelting process of titanium-gold-containing ingots. Background Art

[0002] Titanium alloys have become important structural materials in aerospace manufacturing due to their low density, high specific strength, thermal strength and corrosion resistance. At present, vacuum consumable arc melting (VAR) or electron beam cooling furnace process (EB) is mainly used for large-scale industrial production of titanium alloy ingots. In order to make the titanium alloy composition uniform and meet the quality requirements, it is usually necessary to use secondary and tertiary vacuum consumable arc melting processes to remove inclusions in the alloy. After the secondary and tertiary vacuum consumable arc melting processes come out of the furnace, the titanium alloy ingot needs to be cooled to below 80°C before the next step of the finished product melting process or machining process can be carried out. Therefore, rapid cooling of the titanium alloy ingot is crucial to improving production efficiency.

[0003] The "Mobile Cooling Device for Titanium and Titanium Alloy Ingot Melting Process" (Patent No.: CN202021428251.7) applied by Xinjiang Xiangrun New Materials Technology Co., Ltd. cools the ingot by designing a mobile bracket. At the same time, the height of the axial flow fan can be adjusted according to the diameter of the ingot, so that the distance between the axial flow fan and the ingot to be cooled is in a favorable cooling position to ensure the cooling effect. However, it can usually only cool a single ingot, and the fan speed is low, the number of fans is small, there is a cooling blind spot, and the cooling efficiency needs to be improved. When faced with a large number of titanium alloy ingots to be cooled, it will face greater cooling pressure, affecting the rhythm of the titanium alloy smelting production process.
