Description
Technical field
It the utility model is related to a kind of specific purpose tool for clearing up nitrogen seal ring air holes.
Background technology
The nitrogen seal ring assembling that steelwork converter uses at present is welded using Q235B material steel plates δ=10mm.Converter nitrogen
Seal ring is circular device, and position is sealed on pedestal in revolving furnace fume hood oxygen rifle entrance water cold sleeve top nitrogen and is fixed on oxygen gun body
On, its center line overlaps with oxygen rifle center line.The effect of nitrogen seal ring is run downwards to when blowing in oxygen rifle when being converter smelting, journey
Sequence setting medium pressure nitrogen gas is opened, and nitrogen is sealed pedestal and set by nitrogen to be filled in the uniform nitrogen aperture of annulus to nitrogen seal ring inner space
Nitrogen, its inner space formed after certain pressure again by inside nitrogen seal ring in the uniform intensive hole of nitrogen of annulus to now by
The oxygen rifle outer tube of nitrogen seal ring parcel forms nitrogen jet current, so as to realize sealing gland, reaches the outer row for preventing flue gas in revolving furnace fume hood.
Subject matter existing for the nitrogen seal ring used at present is as follows：Terminate oxygen rifle smelting and improve to when more than position is blown,
Now nitrogen envelope pedestal stops supplying nitrogen, and the high temperature accumulated slag and cold steel particles on the oxygen rifle body of a gun freely drop or handled oxygen rifle body of a gun accumulated slag
Cold steel, slag particle, which drop, during cold steel easily causes nitrogen envelope pedestal to be blocked in the uniform nitrogen air holes of annulus, this nitrogen envelope pedestal nitrogen wind
Bore dia is φ 6mm.After circulation is smelted, nitrogen brings the fine particle of some blocking nitrogen envelope pedestals to nitrogen seal ring into
The intensive air holes of nitrogen easily causes blocking, this internal a diameter of φ 4mm of the intensive air holes of nitrogen.1st, intensive air holes, which blocks, exceeds 1/5
Total hole count when, nitrogen envelope effect is poor, at oxygen rifle nitrogen envelope pedestal converter gas discharge capacity is big and converter gas in high level
CO, easily pollute power house environment and endanger worker health.2nd, because air holes block cause the nitrogen seal ring replacement cycle for half a year/time and
Processing cost is 20000 yuan/part, and service life is shorter, influences normally to produce.
The content of the invention
The purpose of this utility model is to provide a kind of specific purpose tool for clearing up nitrogen seal ring air holes, can ensure equipment safety
Use, extend the replacement cycle caused by nitrogen seals pedestal and nitrogen seal ring inside air holes blocks, the online smelting process of stable converter
Nitrogen seals effect, reduces the outer discharge capacity of converter gas.
The purpose of this utility model is achieved in that a kind of specific purpose tool for clearing up nitrogen seal ring air holes, including handle, hand
The length of handle is 400mm, and handle one end is fixedly mounted a nose cone, a diameter of 16mm of top surface of nose cone, nose cone
Basal diameter is 2mm, and the height of nose cone is 100mm, and nose cone is divided into two parts up and down, by mutual between upper and lower two parts
The screwed hole and stud of cooperation are connected, and groove is uniformly arranged at intervals on nose cone lower, outer perimeter wall.
Nitrogen seal ring specific purpose tool is cleared up by designing, it is safe to nitrogen envelope pedestal and nitrogen seal ring using that can be realized during blowing out
The cleaning of internal intensive air holes, stable nitrogen envelope effect, environment and favourable worker are physically and mentally healthy in purification plant；The nitrogen seal ring life-span 6
The moon was improved to 31 months, and cleaning nitrogen seal ring sealing gland hole does not influence to produce.
Brief description of the drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is main structure diagram of the present utility model.
Embodiment
A kind of specific purpose tool for clearing up nitrogen seal ring air holes, as shown in figure 1, including handle 1, the length of handle 1 is 400mm,
A nose cone 2 is fixedly mounted in the one end of handle 1, and a diameter of 16mm of top surface of nose cone 2, the bottom surface 5 of nose cone are a diameter of
2mm, the height of nose cone are 100mm, and nose cone is divided into two parts up and down, pass through the screw thread of mutual cooperation between upper and lower two parts
Hole and stud 3 are connected, and groove 4 is uniformly arranged at intervals on nose cone lower, outer perimeter wall.
Claims (1)
1. a kind of specific purpose tool for clearing up nitrogen seal ring air holes, including handle, it is characterized in that：The length of handle is 400mm, handle one
