Problems solved by technology

[0004] The primary problem that is likely to occur during the docking process is that the requirements for the driver's seat bag are high, and when the operation is unstable, the impact of the ladle is likely to cause deformation of the docking device and affect the sealing effect; secondary problems include: molten steel splashing slag and furnace volume slag on the connection The sticky slag or coverage on the surface of the device leads to the inaccurate bonding of the butt joint surface, which affects the sealing effect; affected by the heat transfer and heat radiation of the ladle, the life of the sealing material of the butt joint device is short; the positioning accuracy of the ladle is insufficient, and the horizontal displacement of the butt joint device is compensated too much major issues

Abstract

The invention provides an argon-blowing butt-joint mechanism. An elastic part is designed on a lower connecting plate, so that when a butt-joint device is in but-joint with a butt-joint surface of a trunnion box, the lower connecting plate can be upwards bounced all the time to press and fit to an upper butt-joint plate, and therefore, sealing and automatic communicating of a combined surface whena steel ladle argon-gas butt-joint pipeline is in automatic butt-joint are finally realized. The invention further provides a steel ladle buggy provided with the argon-blowing butt-joint mechanism.

Description

technical field [0001] The invention relates to the technical field of argon blowing at the bottom of a ladle, and more specifically relates to an argon blowing docking mechanism and a ladle trolley. Background technique [0002] The ladle bottom argon blowing process is widely used in various production links from converter tapping to continuous casting, and is a very important process in the molten steel smelting process. Argon gas is blown into the molten steel through the bottom of the ladle, dispersed in the molten steel in the form of bubbles and floats up, and the surrounding molten steel is driven by buoyancy to make the molten steel flow in the ladle, thereby accelerating the melting of the alloy and flux in the ladle and promoting the composition of the molten steel And the uniformity of temperature is conducive to the full floating of slag inclusions and harmful gases, and the realization of argon blowing smelting outside the furnace of molten steel.
