Description

Gas input channel for integral air brick

Technical Field

The utility model relates to a steel smelting field mainly relates to a gas input channel that whole air brick was used.

Background

Argon blowing at the bottom of a steel ladle is taken as an economical, practical and simple molten steel refining means and is generally applied to the external refining of the steel ladle, namely, inert gases such as argon and the like are injected into molten steel through a gas permeable brick arranged at the bottom of the steel ladle to fully stir the molten steel, so that alloys, deoxidizing agents, desulfurizing agents and the like added into the molten steel are rapidly melted and dispersed, the components and the temperature of the molten steel are promoted to be more uniform, and simultaneously bubbles generated by injecting the argon can remove non-metallic inclusions and harmful gases in the molten steel, thereby achieving the purpose of purifying the molten steel. The air brick is an air-permeable functional element in the ladle bottom argon blowing process, and the air permeability of the air brick directly determines the refining effect of molten steel and the quality of steel.

At present, a gas input channel of the air brick is mostly of a straight-through type structure, and inert gas directly enters a gas chamber from a gas source pipeline and then is blown into molten steel through the air channel in the use process of the air brick. Due to the unstable pressure of the gas source or the frequent switching of the gas source in the use process, the molten steel is easy to flow back to enter the gas-permeable channel, and the gas permeability is affected; when the residual height of the air brick is short in the later use period, molten steel can flow back to enter a gas input pipeline, and steel seepage and steel leakage accidents are caused.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a gas input channel that whole air brick was used, the gas permeability and the security that satisfy whole air brick that can be better.

In order to realize the technical purpose, the adopted technical scheme is as follows: the utility model provides a gas input channel that whole air brick was used, gas input channel includes gas input pipeline A and gas input pipeline B, and gas input pipeline A is helical structure, and gas input pipeline B is straight tube structure, and gas input pipeline A's one end is linked together with whole air brick's air chamber, and gas input pipeline A's the other end is connected with gas input pipeline B.

The gas input pipeline A and the gas input pipeline B are detachably connected.

The gas input pipeline A and the gas input pipeline B are connected through threads.

The utility model has the advantages that:

(1) compared with a straight-through gas input pipeline, the gas input pipeline with a spiral structure is used, the input distance of gas before entering the gas chamber is increased, the process of the gas entering the gas chamber is more stable, the pressure distribution in the gas chamber is more uniform, and the air permeability of the air brick is more stable; the slit of the air brick is not easy to clamp steel, and the air brick has good air permeability in the use process. After the gas source connected with the gas input pipeline is closed, a part of gas can still be reserved in the pipeline of the spiral structure to form certain buffering, and the phenomenon that the gas is quickly closed and the molten steel flows back to enter the gas permeable channel of the gas permeable brick to influence the later-stage gas permeability is avoided. Meanwhile, the risk of steel leakage caused by steel seepage of the gas input pipeline can be reduced, and the use safety is enhanced.

(2) The gas input channel is designed to be detachably connected, so that the gas input pipeline can be prevented from being collided in the adjusting and transporting process, and the gas leakage of the pipeline can be prevented.
