Description
Technical field
The utility model relates to a kind of furnace temp control appliance technical field, and particularly a kind of heating furnace is based on the combustion intelligent control system of steel billet temperature monitoring.
Background technology
Heating furnace is the key technology equipment in the steel billet production process, not only is related to product quality, output, also relates to many aspects such as energy-conservation, consumption reduction, reduction of discharging, production cost control.
The thermocouple that the temperature detection of present heating furnace still adopts detects, what thermocouple detected is fire box temperature, measured zone is little, though can react steel billet temperature to a certain extent, but along with working conditions change, as differences such as billet bloom size, material, dress steel temperature, rolling rhythms, the steel billet temperature of same fire box temperature correspondence is different, is difficult to really reflect the steel billet actual temperature.
Heating furnace uses coke-stove gas to act as a fuel at present, and pressure oscillation is bigger, and the burning of heating furnace is controlled under the steady working condition, can satisfy the requirement of production control substantially; But because the limitation of PLC system and conventional control, can't carry out complicated mathematical model computing and network analysis, so the control for coefficient of excess air in the burning is imperfect, the proportioning of air fuel can not remain on the best with working conditions change, not only increase ton steel unit consumption, and the oxidization burning loss rate is very high.Basic now still the dependence manually of the burning of heating furnace control adjusted, and the manually-operated level differs, and can't be at every turn makes respective reaction to disturbing as coal gas sudden change etc. rapidly.Reaction will comparatively slow when fuel and working conditions change like this, and the air-fuel ratio that based on fuel calorific value fluctuation variation adjusting in real time is suitable is burnt and insufficiently caused energy waste and oxidation excessive,
The utility model content
At above-mentioned technical problem, the utility model provides the combustion intelligent control system of a kind of heating furnace based on steel billet temperature monitoring, to improving the quality of products, optimizes burning control, energy-saving and cost-reducingly having important use value.
The technical scheme that its technical problem of solving the utility model adopts is, a kind of heating furnace is based on the combustion intelligent control system of steel billet temperature monitoring, and structure comprises the information gathering part, carries out control section and control of intelligent terminal; Described information gathering partly comprises high-temperature infrared video probe, pressure transmitter, flowmeter, valve opening feedback sensor and frequency conversion feedback sensor, described high-temperature infrared video probe is used to measure steel billet temperature information, and described pressure transmitter is used for pressure detecting; Described execution control section comprises electrically operated valve and frequency converter, and electrically operated valve is used for fuel control, and frequency converter is used for air quantity control; Described control of intelligent terminal is made up of many microcomputers, is divided into burning control of intelligent terminal and temp testing controlling system terminal, connects communication by netting twine between the described microcomputer; Described control of intelligent terminal partly is connected communication with the execution control section with information gathering by open field bus.
The beneficial effect that the utility model produces is, native system finishes simultaneously that inner operating monitors and the system of heating billet surface temperature detection and burning Based Intelligent Control, to improving the quality of products, optimizes burning control, energy-saving and cost-reducingly having important use value.System adopts Structured Design, and video thermometric clear picture, certainty of measurement height, long service life, installation and maintenance are convenient.Be applicable to that the monitoring billet heating temperature is 800～1400 ℃ a smelting and heating.By real time video image and the steel billet infra-red radiation collection of illustrative plates that obtains heating cycle in the heating furnace, machine analyzing and processing as calculated, identify the profile of heating steel billet, visible surface chromatogram to the heating steel billet is analyzed, calculate surface temperature, in real time, accurately obtain heating billet surface Temperature Distribution parameter, and information in time can be fed back to combustion intelligent control system.
