Automatic butt-jointing device for argon blowing pipeline of molten steel tank

Abstract

The invention provides an automatic butt-jointing device for an argon blowing pipeline of a molten steel tank, which can replace the original manual butt-jointing operation, can protect the safety of the personnel, and simultaneously can solve the problem that the existing automatic butt-jointing device has short service life and unreliable butt joint. The automatic butt-jointing device comprises a female joint end arranged at the molten steel tank, and a male joint end connected with the argon blowing device of transfer equipment; the female joint end and the male joint end are internally provided with argon passages correspondingly; and the argon passages of the female joint end and the male joint end are connected with the molten steel tank and the argon pipelines of the argon blowing device of the transfer equipment respectively. The automatic butt-jointing device is characterized in that the female joint end is arranged in the standing tank seat of the molten steel tank; and the male joint end is arranged in the bearing tank seat of the molten steel tank of the transfer equipment.

Description

technical field [0001] The invention relates to the technical field of accessory devices for metallurgical molten steel tanks, in particular to an automatic docking device for an argon blowing pipeline of a molten steel tank. Background technique [0002] During the molten steel transfer process under the furnace, the molten steel tank needs to blow argon to the molten steel to achieve the effect of stirring the molten steel. Generally, argon blowing devices are usually installed on the rotating equipment under the furnace, such as the molten steel tank car and the ladle turret. When the molten steel When the tank is dropped, it is necessary to connect the argon pipeline of the molten steel tank with the argon blowing device on the transfer equipment. At present, most of the docking operations are performed manually through quick-change joints. Due to the heat dissipation of the molten steel during transfer It will cause the precipitation of sulfur and phosphorus in the molt...
