Abstract
The utility model relates to a gas supply pipeline of an argon oxygen furnace, which is mainly used for a gas supply facility in the stainless steel production of metallurgical industry. The gas supply pipeline comprises pipelines for conveying three kinds of gases, and a cut-off valve is arranged on each gas supply pipeline. The gas supply pipeline is characterized in that a bleeding valve and at least two adjusting valves are all arranged on each gas supply pipeline. The gas supply pipeline can effectively prevent the phenomenon of gas blowby of the pipelines, the floater-in-mould accident and the nozzle clogging accident in a crystallizer during the processes of continuously casting and casting titanium steel are avoided, thereby the production cost of enterprises is reduced, and the quality of products is improved.
Description
Technical field:
The utility model is mainly used in the air feed facility in the metallurgy industry production stainless steel, is specifically related to the steam line of argon oxygen stove.
Background technology:
Argon oxygen stove is a capital equipment of producing decarburization in the stainless steel, and the main gas that uses has oxygen, nitrogen, argon gas, mainly uses oxygen and nitrogen in the heat of oxidation, and reduction period uses oxygen and argon gas.Because the admission line of argon oxygen stove is a pipe, lean on a control valve and a stop valve on each gas pipeline to control for the pipeline of argon oxygen stove gas transmission.
In the heat of oxidation, the normal air feed of oxygen and nitrogen stops the gas transmission of argon gas pipeline, and at this moment the pressure in the argon gas pipeline is greater than the pressure of nitrogen pipeline, if the gas leakage of the stop valve of argon gas pipeline, argon gas will " be scurried " in nitrogen pipeline, causes the argon gas waste; At reduction period, stop the nitrogen pipeline gas transmission, the normal air feed of oxygen and argon gas, at this moment the pressure in the nitrogen pipeline is greater than the pressure of argon gas pipeline, if the gas leakage of the stop valve of nitrogen pipeline, nitrogen will " be scurried " in the argon gas pipeline, cause steel quality to descend, can cause molten steel to be scrapped when serious.
Summary of the invention:
The utility model aims to provide the steam line of the argon oxygen stove that prevents " scurrying " gas, to improve the product quality of molten steel.
The realization the technical solution of the utility model is: comprise the pipeline of carrying three kinds of gases, stop valve all is set on the pipeline of every kind of gas, it is characterized in that all being provided with on the pipeline of every kind of gas and diffuse valve and at least two control valves.
The utility model can prevent effectively that pipeline from " scurrying " the gas phenomenon, prevents " knot fish " accident and nozzle clogging accident in the crystallizer in the Ti-containing steel continuous casting process, for enterprise has reduced production cost, has improved product quality.
The utility model is simple in structure, and is easy to use, invests little, effective.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1. oxygen channel 2. control valves 3. stop valves 4. diffuse valve 5. stop valves 6. argon oxygen stoves 7. nitrogen pipelines 8. argon gas pipelines
The specific embodiment:
The specific embodiment of the present utility model is not limited to following embodiment, and different embodiment can be set according to actual needs.
Embodiment: shown in Figure 1, present embodiment comprises oxygen channel 1, nitrogen pipeline 7, the argon gas pipeline 8 of carrying gas, all fixedly mounts control valve 2 on each pipeline, diffuses valve 4 and two stop valves 5.
Illustrate: control valve adopts the ZXP type in the present embodiment; Diffuse valve and adopt the QS43Y type; Stop valve adopts the ZMQ type.Parts in the present embodiment are the product of buying on the market, the description of its structure of Therefore, omited and annexation.
