Abstract

The invention relates to the technical field of metallurgical equipment, in particular to a vacuum consumable electrode furnace crystallizer cooling device and a cooling method thereof. The crystallizer comprises a crucible, a waterproof sleeve, a water distribution sleeve and a crystallizer shell are sequentially arranged on the outer wall of the crucible from inside to outside, a water inlet layer is arranged between the outer wall of the crucible and the waterproof sleeve, a water storage layer is arranged between the waterproof sleeve and the water distribution sleeve, and a water return layer is arranged between the water distribution sleeve and the crystallizer shell; a water inlet is formed in the lower part of the crucible and is connected with a water inlet and outlet; and one end of a water return port of the water return layer is arranged on the crystallizer shell, and the other end of the water return port is connected with a water return inlet. According to the vacuum self-consuming furnace crystallizer cooling device and the cooling method thereof, when molten metal in the crucible is crystallized, crystal grains are finer, arrangement is more regular, and the metallographic structure of a metal ingot is more uniform.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, and in particular relates to a vacuum consumable furnace crystallizer cooling device and a cooling method thereof. Background technique [0002] Vacuum consumable furnace is the equipment that uses vacuum technology to produce special steel. Usually, electric arc furnace, electroslag furnace, etc. are used as front-end equipment, and then the electrodes produced by it are further remelted and refined. As a remelting equipment, the vacuum consumable furnace can effectively improve the crystal structure and toughness of the material, and can effectively improve the comprehensive service life of the steel material, thereby obtaining higher quality alloy materials. Vacuum consumable furnaces are used to smelt special steels, reactive and refractory metals such as titanium, molybdenum, and niobium. It is usually used in key parts in some high-end fields, such as aerospace, aviation, h...
