Description
Technical field
This utility model is related to converter smelting technology, particularly to a kind of energy-conserving and environment-protective converter slag-making system.
Background technology
Quick lime is CaO, is the topmost slag making materials of pneumatic steelmaking, can produce substantial amounts of more than needed in converter steelmaking process
Heat, needs to carry out dynamic cooling with coolant, but quick lime cooling-down effect is inconspicuous, relatively costly, increases consumption of quicklime,
Not only cause the waste of heat, and pollute environment.
Utility model content
This utility model is to solve above-mentioned problem, there is provided a kind of energy-conserving and environment-protective converter slag-making system, its solution
The technical scheme of technical problem is：
A kind of energy-conserving and environment-protective converter slag-making system, including disintegrating machine, blanking bin, high hopper and converter；Described Ore
After exploitation, through disintegrating machine, limestone crushing is become the stone of 5mm～50mm, stone transports directly to converter through lorry
Ground blanking bin connection, described ground blanking bin is passed through lifting conveyer belt and is connected with high hopper, and high hopper is through scale hooper and nitrogen
Envelope chute converter is connected.
The step of energy-conserving and environment-protective converter slag-making system slag making is as follows：
1) crush：Limestone crushing by building stones factory；
2) blanking bin：The limestone having crushed is transported to ground blanking bin, stand-by；
3) high hopper：The limestone of ground blanking bin is risen to high hopper；
4）Converter is added：High hopper is quantitatively added in converter in batches；First adds：Converter is opened when blowing the initial stage,
Add limestone 3.5-4.5kg/t；Second batch adds：Open when blowing 5min, add limestone 4.5-5.5kg/t, Calx 2.5-
3.5kg/t；3rd batch of interpolation：Open when blowing 6.5min, add limestone 5.5-6.5kg/t, Calx 2kg/t；According to in-furnace temperature
Situation more than needed, only adds part replacing lime with limestone in the second batch of material, and the ratio of limestone and Calx presses 1：0.6 conversion；Stove
The reaction of interior generation CaCO3=CaO+CO2, because containing a large amount of SiO2 in slag, causes for stoping CaO and SiO2 from reacting generation quality
The high CaSiO3 of close, fusing point, T, FeO, the MnO in stove are high, so that the CaSiO3 of limestone surfaces is decomposed, make limestone block enter one
Step reaction, makes to contain enough CaO content in slag.
The invention has the advantages that：
This utility model utilizes thermodynamics in Converter, kinetics and redox reaction, the sintering of limestone by
Rotary kiln is transferred directly in Converter and carries out it is ensured that converter dephosphorization needs and slag splashing needs；Not only reduce limestone
Be fired into the process energy consumption of Calx and inter process has bad luck cost, and reduces the discharge of dust and carbon dioxide.
Brief description
Fig. 1 is a kind of process chart of present invention energy-conserving and environment-protective converter slag-making system.
1. disintegrating machine, 2. blanking bin, 3. elevating conveyor, 4. high hopper, 5. scale hooper, 6. converter.
Specific embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described.
A kind of energy-conserving and environment-protective converter slag-making system, including disintegrating machine 1, blanking bin 2, high hopper 4 and converter 6；Described
Disintegrating machine 1 passes through lorry broken limestone, moves converter or ground blanking bin 2 to, and described ground blanking bin 2 passes through elevating conveyor
3 are connected with high hopper 4, and high hopper seals chute converter 6 through scale hooper 5 and nitrogen and is connected.
The step of energy-conserving and environment-protective converter slag-making system slag making is as follows：
1) crush：The limestone of building stones factory is broken in disintegrating machine 1, it is broken into the stone of 5mm～50mm；
2) blanking bin：The limestone having crushed is transported to converter 6 or ground blanking bin 2 by lorry, stand-by；
3) high hopper：The limestone of ground blanking bin is risen to high hopper 4 by elevating conveyor 3；
4）Converter is added：The limestone of high hopper 4 is quantitatively added in converter in batches；First adds：Converter is opened
When blowing the initial stage, add limestone 3.5kg/t;Second batch adds：Open when blowing 5min, add limestone 5kg/t, Calx 3kg/t；
3rd batch of interpolation：Open when blowing 6.5min, add limestone 5.5kg/t, Calx 2kg/t；According to in-furnace temperature situation, only second
Batch of material adds part replacing lime with limestone, and the ratio of limestone and Calx presses 1：0.6 conversion；There is CaCO3=CaO+ in stove
The reaction of CO2, because in slag contain a large amount of SiO2, for stop CaO and SiO2 react generate quality densification, fusing point high
CaSiO3, T, FeO, the MnO in stove are high, so that the CaSiO3 of limestone surfaces is decomposed, so that limestone block is reacted further, make stove
Enough CaO content are contained in slag.
The above, only this utility model preferably specific embodiment, but protection domain of the present utility model is not
It is confined to this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in
Change or replacement, all should cover within protection domain of the present utility model.
