Abstract
The utility model discloses a device for preventing molten steel from permeating a gas permeable brick of a steel ladle. The device comprises a gas permeable brick which is positioned on the side wall of the steel ladle, and a gas delivery pipeline which is communicated with the gas permeable brick, wherein a gas storage tank is arranged on the gas delivery pipeline, and a check valve is installed on the rear end of the gas delivery pipeline. The capacity of a gas outlet pipe is not less than 0.03 cubic meter. The gas delivery pipeline of the gas permeable brick is improved, after the gas storage tank is additionally arranged, a certain amount of residual gas is still left in the gas delivery pipeline after gas blowing is stopped, a certain gas pressure is ensured, so that molten steel cannot permeate into the cracks of the gas permeable brick, equipment is enabled to effectively operate for a long time, the improved structure is simple and easy to realize, a good use effect is obtained, and the device can be excellently popularized and implemented.
Description
Technical field
The utility model relates in field of steel-making the technology of refractory brick application and improvement, is specifically related to the air tight brick of a kind of ladle and oozes the steel device.
Background technology
In field of steel-making, the ladle sidewall is provided with air brick, be connected with gas pipeline on air brick, so that to the technique of blowing in ladle, and ladle of the prior art molten steel after stopping internally air blowing can infiltrate the air brick brickwork joint again along going out air cleft, cause the air brick brickwork joint to be blocked, affect the permanently effective use of equipment, affect steel quality.
The utility model content
The purpose of this utility model is problem and the defective that exists for existing ladle air blowing technology, provides a kind of and can prevent that the molten steel reverse osmosis from entering the device of air brick brickwork joint.
The utility model is achieved through the following technical solutions: the air tight brick of a kind of ladle oozes the steel device, comprise the air brick that is positioned at the ladle sidewall, and the gas pipeline that is communicated with air brick, be provided with air accumulator on this gas pipeline, and at the end of this gas pipeline, check valve be installed.
The capacity of described escape pipe is not less than 0.03 cubic metre.
The capacity of described ladle is 60～200 tons.
The utlity model has following advantage: by the air brick gas pipeline is transformed, increase make after air accumulator stop blowing afloat after gas pipeline inside also have a certain amount of residual gas, guarantee certain gas pressure, allow molten steel can't infiltrate the air brick brickwork joint, guarantee the permanently effective operation of equipment, reconstruction structure is simple easily to be realized, result of use is good, is beneficial to very much promotion and implementation.
Description of drawings
Fig. 1 is the installment state schematic diagram that the air tight brick of the utility model ladle oozes the steel device;
Fig. 2 is the local structure for amplifying schematic diagram of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, number in the figure 1 is ladle, and 2 is air brick, and 3 is gas pipeline.Install check valve 5 and air accumulator 4 on the air brick gas pipeline, make stop blowing after inside also have a certain amount of residual gas, guarantee certain gas pressure, allow molten steel can't infiltrate the air brick brickwork joint.
Check valve requires to use high-temperature valve; The air accumulator profile is any, and volume must not be less than 0.03 cubic metre.
This device is applicable to 60～200 tons of ladles.
