Abstract

The invention relates to the refining field of the steel through vacuum treatment and particularly relates to an electrode rotation double-station electric arc heating vacuum treatment device and a using method thereof. The electrode rotation double-station electric arc heating vacuum treatment device comprises two treatment stations. Each treatment station comprises a vacuum tanker (1) and a vacuum tank (2). The device is characterized in that each treatment station further comprises a lifting device (3), a vacuum tank cover (4), a jacking device (5) and the like. The using method of the electrode rotation double-station electric arc heating vacuum treatment device comprises the following steps of: heating the electrode; blowing argon at bottom and stirring; and degassing in vacuum. The device provided by the invention has the advantages of low equipment investment, short refining period, high refining quality and flexible combination.

Description

technical field [0001] The invention relates to the field of steel refining using vacuum treatment, in particular to an electrode rotating double-station arc heating vacuum treatment device and a use method thereof. Background technique [0002] In the refining equipment outside the furnace, there is a vacuum degassing arc heating device, that is, VAD vacuum smelting equipment. The advantage of using this equipment is that the molten steel can be heated under vacuum, and the external environment of the molten steel is good during refining. Therefore, compared with vacuum treatment (VD) and heating (LF) which are divided into two stations, the time for auxiliary operations such as bag lifting, operation, and cover lifting is reduced. However, the electrode seal of this device is under the conditions of high temperature, high dust, and electrode vibration, so it is not suitable to do a good job. It is one of the main reasons affecting its popularization and application in spe...
