Description
Technical Field
The utility model relates to a smelting equipment field, ladle argon bottom-blown air brick prevents stifled device promptly.
Background
In the prior art, the smelting ladle bottom argon blowing treatment is a simple external refining method for degassing molten steel and removing non-metallic inclusions. The method has simple process and remarkable refining effect, ensures that the components and the temperature of the molten steel are uniform before casting, can obviously reduce the casting temperature of the casting, realizes the normalization of the continuous casting process, improves the impact toughness of steel and the like. An air supply element (air brick) is arranged at the bottom of the steel ladle, and argon is blown into molten steel through the air brick at the bottom to form a large amount of fine argon bubbles. The air brick not only has certain air permeability, but also has certain high-temperature strength and better rapid cooling and heating resistance, and can bear molten steel scouring. But the defects are that after argon blowing is stopped, molten steel enters the argon blowing holes of the air brick to block the air brick, so that the subsequent use of the ladle is influenced, and the service life of the air brick is shortened.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the aforesaid not enough and provide a reduce air brick and block up, improve life's ladle argon gas bottom blowing air brick prevents stifled device.
The technical solution of the utility model is that: ladle argon gas bottom-blowing air brick prevents stifled device, including the air brick of ladle bottom, the air brick is connected with the argon gas main line of taking the check valve, is connected with the branch pipeline on its characterized in that argon gas main line between air brick and the check valve, is connected with adjustable one-way choke valve and argon gas minute-pressure gas pitcher on the branch pipeline.
The utility model has the advantages that: 1. by installing the argon micro-pressure gas tank, the one-way valve and other elements in parallel on the argon bottom blowing pipeline of the steel ladle, after the steel ladle stops blowing argon, micro-positive pressure can be continuously kept in the air brick, surface tension is formed by the argon in the air brick and the molten steel, the molten steel can be prevented from entering the air hole of the air brick, the defect that the air brick is blocked by the argon bottom blowing process of the steel ladle is overcome, the molten steel treatment quality, the molten steel treatment efficiency and the continuity are ensured, the service life of the air brick is prolonged, and the follow-up connection of steel-making production is effectively ensured. 2. After argon blowing is stopped, micro-positive pressure can be automatically kept inside the air brick, molten steel is prevented from flowing into the air brick to block the air blowing hole, and continuous service life of the air brick is guaranteed. 3. The structure is simple, the installation is convenient, the reliability and the durability are realized, the transformation and the upgrade of the existing equipment are convenient, the equipment manufacturing cost is low, and the economical efficiency is good.
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Drawings
Fig. 1 is a schematic diagram of the present invention.
FIG. 2 is a schematic view of the vent hole structure of the air brick.
Detailed Description
Referring to fig. 1 and 2, the names of the components are as follows: the device comprises a check valve 1, an argon micro-pressure gas tank 2, a piston 3, a spring 4, an adjustable one-way throttle valve 5, a three-way connecting piece 6, a gas permeable brick 7, an argon main pipeline 8 and a branch pipeline 9.
Referring to fig. 1 and 2, the ladle argon bottom-blowing air brick anti-blocking device comprises an air brick 7 at the bottom of a ladle, wherein the air brick 7 is connected with an argon main pipeline 8 with a one-way valve 1. A branch pipeline 9 is connected on an argon main pipeline 8 between the air brick 7 and the one-way valve 1, and an adjustable one-way throttle valve 5 and an argon micro-pressure gas tank 2 are connected on the branch pipeline 9. The ladle argon main pipeline one-way valve 1 is connected with the air brick 7 through a three-way connecting piece 6, and one-way irreversible flow of argon to the air brick 7 is realized. The adjustable one-way throttle valve 5 is connected with the argon micro-pressure gas tank 2, and the adjustable one-way throttle valve 5 is connected with the three-way connecting piece 6. Thereby realizing that the argon in the argon micro-pressure gas tank 2 automatically flows to the air brick after the argon blowing is stopped. Spring 4 is connected with piston 3 and is installed in argon gas minute-pressure gas pitcher 2, and during blowing argon, argon gas promotes piston 3 compression spring 4, blows the argon and stops the back, and spring 4 promotes piston 3, sends out argon gas outside argon gas minute-pressure gas pitcher 2.
The use method or the working principle is as follows: when the ladle carries out argon bottom blowing, the argon gas passes through main pipeline check valve 1 and gets into air brick 7 and argon gas minute-pressure gas pitcher 2, when carrying out argon gas bottom blowing, aerifys the pressurization to argon gas minute-pressure gas pitcher 2. After argon blowing is finished, an argon gas pipeline is disconnected, the argon gas micro-pressure gas tank 2 starts to slowly and continuously release argon gas into the air brick 7 through the adjustable one-way throttle valve 5, micro-positive pressure is kept in the air brick 7, and molten steel is prevented from entering the air brick 7 by utilizing surface tension of the molten steel, so that air hole blockage of the air brick 7 is prevented, air permeability of the air brick 7 is ensured, and the service life of the air brick 7 is prolonged.
The above description is only exemplary of the present invention, and the various illustrations do not limit the essence of the present invention.
