Title:
CRYSTALLIZER FOR METAL ELECTROSLAG REMELTING, ELECTROSLAG REMELTING DEVICE AND ELECTROSLAG REMELTING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/135223
Kind Code:
A1
Abstract:
A crystallizer for metal electroslag remelting, an electroslag remelting device and an electroslag remelting method, belonging to the technical field of metal smelting and solving the problem that large electroslag ingots cannot be produced at present. The crystallizer (5) for metal electroslag remelting comprises an upper crystallization chamber (7), a middle crystallization chamber (8), and a lower crystallization chamber (9) which are sequentially stacked from top to bottom; the upper crystallization chamber (7), the middle crystallization chamber (8), and the lower crystallization chamber (9) are each provided with an upper smelting cavity (71), a middle smelting cavity (81), and a lower smelting cavity (91) which vertically penetrate through the corresponding crystallization chamber separately; the middle smelting cavity (81) is in an inverted cone shape, the largest end of the middle smelting cavity (81) is in butt joint with the upper smelting cavity (71), and the smallest end of the middle smelting cavity (81) is in butt joint with the lower smelting cavity (91). Solidified electroslag ingots are extracted from the crystallizer, the stability of the whole electroslag process is not affected, the high-temperature electroslag ingots are directly subjected to water cooling, and the cooling speed is increased. Due to the special crystallizer structure, it can be guaranteed that when the electroslag ingots are subjected to water cooling, the temperature field of molten slags in a high-temperature molten pool is influenced by generated large cooling, and thus electroslag remelting can be smoothly carried out.
