Description
Technical field
The present invention relates to technical field of ferrous metallurgy, specifically a kind of intelligence steel-making system based on converter gas analytical technology
System.
Background technique
It it is well known that China is a big steel country, but is not a steel power.WSD(World Steel
Dynamics) iron and steel enterprise's year list competitiveness ranking in 2017 that the whole world has most competed, the treasured that China ranks the first are military
Group ranked tenth name in the world.Domestic steel mill at this stage produced steel products in quality, kind and steel output per capita, enterprise
Industry benefit is compared with external steel mill all has big gap.
Country's BOF steelmaking shop at present, most of is all mini-medium BOF plants, and heat size is in 100t hereinafter, these converters can not be pacified
Dress pays rifle equipment, cannot also realize intelligent steel-making, and for domestic large and medium-sized BOF steelmaking shop, although being mounted with that paying rifle sets
It is standby, but plant maintenance and process material consumption are larger, and most of steel mill's converter operations are made steel by artificial experience.One
Divide large-scale state-owned enterprise, although automatic Steelmaking operation is horizontal higher, majority uses the automatic Steelmakings for paying gun-shaped formula, fails to realize
One-touch intelligence steel-making, and the effect that pair rifle equipment uses is undesirable, and converter operation mainstream is still by artificial warp
Steel-making is tested, there are no small gap, this artificial experience steel-making mode is also difficult to produce for the automation and intelligence of distance steel-making
The product of high quality out.Requirement with the continuous development and progress of China's economy, to steel and iron industry intelligence manufacture, green production
It is increasingly urgent to, how in the intelligence for realizing pneumatic steelmaking, especially solves domestic mini-medium BOF plants at present and make steel presence automatically
The problem of, have become the key link that China's steel and iron industry realizes intelligence manufacture.
The present invention be exactly mainly be exactly the intellectually and automatically for solving the problems, such as pneumatic steelmaking smelting operation process.
Current country's 120t or more converter, the overwhelming majority have used sublance dynamic control technology, have passed through number first in blowing
Slag charge, coolant, flow of oxygen required for model static cost control determines are learned, the preceding 2~3min of end is closed in blowing and falls sublance,
Measurement bath temperature, carbon content are simultaneously extracted molten steel sample (referred to as " TSC " is measured), are then carried out according to " TSC " measurement result
Necessary adjustment is fallen sublance measurement molten steel temperature, carbon content and extracts molten steel sample (letter again to blowing end point after finishing blowing
Referred to as " TSO " is measured).
The application of sublance dynamic control technology significantly improves converter terminal hit rate, but there is also many deficiencies for the technology:
1) in 75% or so duration of blast (before " TSC " measurement), reaction in furnace situation is unknown, and (molten bath ingredient, takes off temperature
Carbon speed etc.)；
2) due to the error (especially steel scrap) of quality of furnace charge, ingredient, cooling energy etc., a great deal of heat " TSC "
Measurement result deviates target, and strategies for taking " over-blowing " carbon elimination to protect outlet temperature, cause molten steel [O] and clinker more in the case of this
FeO content improves；
3) sublance plant maintenance and measuring probe expense increase production cost；
4) oxygen supply intensity need to be reduced when " TSC " is measured, " TSO " measurement needs 1min or so time after finishing blowing, waits examination
Sample chemical analysis results then need the more time, extend the converter smelting period；
5) equipment investment expense is relatively high.
Although domestic Ji Jia state-owned enterprise 100t BOF steelmaking shop is equipped with flue gas analysis (mass spectrograph) equipment of import, realize
Full-automation steel-making, but due to mass spectrograph smoke gas analysis equipment there are the problem of it is more, plant maintenance amount is big, while the response of instrument
Time is long, brings difficulty for intelligent steelmaking model technology, therefore is also used widely without steel mill at home.
Summary of the invention
It is above-mentioned to solve the purpose of the present invention is to provide a kind of intelligent steelmaking system based on converter gas analytical technology
The problem of being proposed in background technique.
To achieve the above object, the invention provides the following technical scheme:
A kind of flue gas analysis profession detection instrument, the flue gas analysis profession detection instrument includes flue gas analysis gas analysis
Instrument and converter audio frequency slag melting monitor system；
Converter audio frequency slag melting monitoring system includes converter, is disposed with from left to right above the right side of converter into water
Mouth, sound sample device and nitrogen inlet, water inlet lower section are provided with water outlet, are provided with water pipe and tracheae below water outlet,
Water pipe and tracheae tail end be respectively provided with pressure regulation, Air-regulating valves and connect that hose connects to silk；
The converter audio frequency slag melting monitoring system further includes sampler, probe, preprocessor, sonication instrument, data
Acquisition device, data processing computer and water and air distributing system, the right end of the sampler are provided with probe, the sampling dress
