Automatic centering argon blowing device connector

Abstract

The invention discloses an automatic centering argon blowing device connector, which comprises a support, a socket movably connected with the support, and a plug component arranged below the socket, wherein the plug component comprises a guide sleeve of which the upper end is provided with an opening, a plug arranged in the guide sleeve and matched with the socket, and an elastic piece arranged below the plug and pressed against the plug; a three-claw positioning device is arranged at the periphery of the socket; and air holes for making argon pass through are respectively formed on the plug and the socket. Due to the plug and the socket which are matched mutually, and the three-claw positioning device arranged at the periphery of the socket, the automatic centering argon blowing device connector enables an argon blowing device at the bottom of a steel ladle to automatically and accurately fall down on a steel ladle transportation truck; in the absence of a limiting device on the steel ladle transportation truck or the steel ladle, a crane driver can operate conveniently; therefore, the connecting time for the argon blowing device at the bottom of the steel ladle is shortened greatly, the energy is saved, and the refining production efficiency is improved.

Description

technical field [0001] The invention relates to the field of refining production outside the LF furnace, in particular to a connector for an automatic centering type argon blowing device. Background technique [0002] In the production of converter steelmaking, more and more varieties of steel are replaced by the out-of-furnace refining production process of ladle refining furnace (LF furnace for short). The production capacity reduces the production cost. [0003] Refining outside the LF furnace is to blow argon gas into the bottom of the ladle when the alloy raw materials are added to the ladle, so that the alloy components and the molten steel in the ladle can be mixed more evenly, and the yield of the alloy can be maximized. Argon blowing at the bottom of the ladle is to blow inert gas such as argon into the molten steel through the breathable brick installed at the bottom of the ladle, so that the molten steel can circulate in the ladle, and the molten steel is fully s...

AI Technical Summary

Problems solved by technology

[0005] 1. The crane driver must control the ladle at high altitude so that it falls accurately on the center point of the three-dimensional coordinates of the ladle transport vehicle, which increases the difficulty of the operation of the crane driver and increases the fatigue of the driver;

[0006] 2. This positioning technology also prolongs the operation time of argon blowing at the bottom of the ladle, increasing the production cost of molten steel heating up; 3. The buffer spring of the receiving device on the ladle car has no fixed guide frame, can swing in space, and is easy to break. Once falling off, it is easy to damage the limit block, or even damage the argon blowing connection device, resulting in damage to the argon blowing device at the bottom of the ladle, affecting the refining production outside the LF furnace
