Description
Technical field
The utility model belongs to field of iron and steel smelting, and in particular to a kind of converter of anti-clinker splash.
Background technology
Bessemerize initial stage, half steel temperature is relatively low in stove, molten steel phosphorus content is higher, and when oxygen gun blowing, liquid steel temperature is fast
Speed rise, when temperature is raised to a certain degree, reaction between carbon and oxygen breaks out progress suddenly in stove, produces a large amount of carbon monoxide and titanium dioxide
Carbon so that clinker volume sharply increases, and clinker largely goes out fire door, causes clinker splash, blows the later stage, and misoperation can cause
Metal expulsion.
Clinker splash is difficult to avoid that in converter production process, and clinker splash can make it that fire door furnace crown dry slag is severe, lead
Cause converter negative moment occur, disturb the normal production operation of converter, have impact on converter safety in production, and splash carry-over contains
There is substantial amounts of metal, reduce tap, add steel technology.
Utility model content
The purpose of this utility model is to provide a kind of converter of anti-clinker splash, and the converter can prevent converter slag from spraying
Splash, reduce iron and steel stock loss, reduce production cost, reduce fire door furnace crown dry slag, avoid converter and produce negative moment, really
The normal smelting of converter safety is protected.
Technical scheme is used by the utility model:
A kind of converter of anti-clinker splash, converter outer wall are provided with least one circle compressed gas house steward, compressed gas house steward
Compressed gas branch pipe is distributed with along the line, compressed gas branch outlet is communicated with fireclay nozzle brick, and fireclay nozzle brick is around converter axis
Inside converter, compressed gas house steward is connected to compressed gas source for uniform and outlet, compressed gas source, compressed gas house steward and
Compressed gas branch pipe composition compressed gas pipeline is provided with valve.
Further, fireclay nozzle brick is enclosed in the refractory brick of converter inwall.
Further, fireclay nozzle brick tilts certain angle to furnace bottom.
Further, the outlet of fireclay nozzle brick is higher than oxygen rifle blowing position.
Further, the source of oxygen of valve and oxygen rifle links, during oxygen gun blowing, valve open, when oxygen rifle closes oxygen, valve
Door is closed.
Further, compressed gas house steward introduces converter outer wall by the non-drive sidespin adapter of converter, on converter outer wall
Compressed gas house steward protected by steel plate.
The beneficial effects of the utility model are:
1. when oxygen rifle, which drops to blowing position, to be blown, valve, fireclay nozzle brick foamed slag table into converter are opened
Compressed gas is blown above face, converter slag splash can be prevented, reduces iron and steel stock loss, reduces production cost, reduce
Fire door furnace crown dry slag, avoid converter and produce negative moment, it is ensured that converter safety is normal to smelt, and when oxygen rifle stops blowing, closes
Valve closing door, stopping are blown into compressed gas.
2. refractory brick serves protective effect to fireclay nozzle brick.
3. fireclay nozzle brick tilts to furnace bottom so that the gas of ejection acts on downwards, significantly more efficient suppression clinker splash.
4. the outlet of fireclay nozzle brick serves the effect of a certain degree of closing oxygen higher than oxygen rifle blowing position.
5. using the valve of linkage, action is automatically controlled, corresponding fast, effect is good.

Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, a kind of converter of anti-clinker splash, the outer wall of converter 1 are provided with a circle compressed gas house steward 4
(can be that a circle can also set multi-turn according to being actually needed), compressed gas branch pipe 5 be distributed with along the line in compressed gas house steward 4,
The outlet of compressed gas branch pipe 5 has fireclay nozzle brick 6, and fireclay nozzle brick 6 is uniform around the axis of converter 1 and outlet is located at converter 1
Inside, compressed gas house steward 4 is connected to compressed gas source, and (compressed gas can be air or other not influence converter 1 and work
Gas), compressed gas source, compressed gas house steward 4 and compressed gas branch pipe 5 form compressed gas pipeline and are provided with valve.When
Oxygen rifle 7 drops to blowing position when being blown, and opens valve, the surface of foamed slag 9 into converter 1 of fireclay nozzle brick 6 is blown
Compressed gas, the clinker splash of converter 1 can be prevented, reduce iron and steel stock loss, reduce production cost, reduce the stove of fire door 1
Cap dry slag, avoiding converter and produce negative moment, it is ensured that the safety of converter 1 is normal to smelt, when oxygen rifle 7 stops blowing, shutoff valve
Door, stopping are blown into compressed gas.
As shown in figure 1, in the present embodiment, fireclay nozzle brick 6 tilts certain angle to furnace bottom so that the gas of ejection to
Lower effect, significantly more efficient suppression clinker splash.The outlet of fireclay nozzle brick 6 serves a certain degree of higher than the blowing of oxygen rifle 7 position
Close the effect of oxygen.
As depicted in figs. 1 and 2, in the present embodiment, fireclay nozzle brick 6 is enclosed in the refractory brick of the inwall of converter 1.It is resistance to
Firebrick serves protective effect to fireclay nozzle brick 6.
In the present embodiment, the source of oxygen of valve and oxygen rifle 7 links, during 7 oxygen blast of oxygen rifle, valve open, oxygen rifle 7 closes oxygen
During gas, valve is closed.Using the valve of linkage, action is automatically controlled, corresponding fast, effect is good.Compressed gas house steward 4 passes through converter
1 non-drive sidespin adapter introduces the outer wall of converter 1, and the compressed gas house steward 4 on the outer wall of converter 1 is protected by steel plate.
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these modifications and variations should all belong to the protection domain of the appended claims for the utility model.
