Argon blowing automatic connecting mechanism for steel melting technique

Abstract

The invention discloses an argon blowing automatic connecting mechanism used in the steel-making process. The argon blowing automatic connecting mechanism comprises a pipeline, ladle joint components and ladle vehicle joint components, wherein the ladle joint components and the ladle vehicle joint components are automatically connected with each other in the form of direct contact of conical surfaces. The invention adopts a technical proposal that direct contact of a spherical head structure of a ventilation shaft during the assembly of ladle vehicle joints and a front end conical surface of a valve core during the assembly of ladle joints is adopted for sealing under the action of a spring force. Because various components all adopt high temperature resistant materials, the service life of the argon blowing automatic connecting mechanism is greatly increased from dozens of minutes to dozens of months. Moreover, the invention greatly reduces the cost, simultaneously reduces the replacement frequency, saves the effective working time and improves the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of auxiliary tool manufacturing in the steelmaking production process, and in particular relates to an argon blowing automatic connection mechanism used in the steelmaking process. Background technique [0002] At present, in the field of auxiliary tool manufacturing technology in the steelmaking production process, the argon blowing connection device in the prior art mainly adopts the structural form of a quick-change joint. It has the advantages of compact structure, small volume, light weight and high temperature resistance. [0003] The quick-change joints in the prior art are widely used in hydraulic, pneumatic transmission and lubricating fluid systems of metallurgy, mining, forging, petroleum, chemical and other machinery, but in the steelmaking production process, there are the following technical defects: [0004] 1. Due to the high temperature of molten steel in the ladle, the rubber gasket in the...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is that in the steelmaking production process, since the rubber gasket in the quick-change joint in the prior art is very easy to melt, the production cost is greatly increased, and the pipeline needs to be disconnected when changing the joint , resulting in technical problems such as low work efficiency, and provides an automatic connection mechanism for argon blowing in steelmaking processes
