Background technology
At present, in the production process of steel, vital work is played in its control to temperature during pouring molten steel
With the control of temperature is primarily referred to as process temperature and outlet temperature control, and any steel of blowing has one to its steel temperature
Fixed requirement, is to influence the key factor of strand yield and quality on the control of molten steel overheat.When molten steel overheat controls to close
In good time, the isometric crystalline region for promoting strand is increased, continuous casting billet structure compact structure, so advantageously reduces center segregation of casting blank and dredge
Pine so that slab quality and yield are optimized, due to the strand technological process of production it is long, link is more, and process temperature control is difficult
Degree is big, ultimately causes middle Baogang's coolant-temperature gage fluctuation greatly, target temperature fulfilling rate is low, to work out a rational cast temperature, leans on
Knowhow is completely not enough, it is necessary to a whole set of temperature control analysis and control program.
The content of the invention
It is an object of the invention to provide a kind of metallurgical furnace temperature control system, by the control to auxiliary material and to temperature
The qualitative cast to molten steel is realized in detection, solves larger and target temperature fulfilling rate bottom the phenomenon of liquid steel temperature fluctuation.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions：
It is of the invention to control mould for a kind of metallurgical furnace temperature control system, including microprocessor, the microprocessor and cis-position
It is connected between block by converter with cis-position control module；Wherein cis-position control module is used to blow rifle position adjustment unit, oxygen
Measure control unit and carbon amounts control unit carries out cis-position addition control；It is connected between the microprocessor and heating module；It is described
Microprocessor is connected with manual control panel, timing module, electron potentiometer and weightometer respectively by A/D converter；Wherein
Manual control panel is used to control the output of the oxygen amount of blowing control unit and carbon amounts control unit manually；Wherein electronic potential
Difference is counted for measuring the temperature in body of heater；Wherein weightometer is used to weigh the quality of oxygen and carbon；The microprocessor
It is connected with display unit；Wherein display unit is used to show oxygen feeding amount, enter carbon amounts and the temperature of monitoring and heat time.
Further, connected between the microprocessor and indicator lamp by D/A converter.
Further, the microprocessor is electrically connected with power module.
Further, connected between the microprocessor and memory by data transmission module.
The invention has the advantages that：
The present invention is provided with electronic potentiometer in stove, the temperature in body of heater is detected in real time, it is ensured that go out in stove body temperature
When now fluctuating, make and timely adjusting, be externally provided with hand held console, when mistake occur in automated procedures, by controlling manually
System is controlled to cast, it is ensured that cast is smoothly completed, and provided with rifle position adjustment unit, the oxygen amount of blowing control unit and carbon
Control unit is measured, the quality of cast is in turn ensured that.
Certainly, any product for implementing the present invention it is not absolutely required to while reaching all the above advantage.
