Description
Technical field
The utility model relates to the converter tapping technical field, refers to a kind of converter tapping control device particularly.
Technical background
Conventionally known to one of skill in the art, in converter steelmaking process, converter body need carry out 360 ° fascinating according to the requirement of technology.Specifically, body of heater is vertical when bessemerizing, its fire door upwards, body of heater certain angle that need tilt when tapping.Molten steel must be poured out from body of heater side tap hole, can not overflow from fire door, and along with the minimizing of molten steel in the stove, body of heater is downward-sloping gradually, has gone out until molten steel.
The converter tapping control protective devices that comparatively extensively adopts at present is principal and subordinate's protection and protection of main cabinet and force moment protection etc.But show that in actual production more than protection can not be satisfied the requirement of production technique fully, adopt above-mentioned technology usually because operator's error causes molten steel to sprinkle or big mouthful of serious accident of overflowing.Control for whole tapping process in original converter steelmaking control design belongs to blank substantially, rely on operator's level of skill to operate fully, tapping is prepared tapping process, the tapping end waits the process control randomness bigger, and serious threat is to safety in production.
Summary of the invention
The purpose of this utility model will provide a kind of converter tapping control device exactly, and this device can be realized controlling fascinating of converter in the converter tapping process according to the requirement of converter steelmaking, has avoided molten steel to sprinkle or big mouth such as overflows at the generation of serious accident.
For realizing this purpose, the converter tapping control device that the utility model is designed, it comprises the motor of controlling converter inclining, wherein, described motor is connected with the signal output part of motor control unit, transmitter is connected with the analog quantity input terminus of described motor control unit by the analog quantity load module, and power module is connected with the power input of described motor control unit, and instruction input module links to each other with the switch signal input terminus of described motor control unit.
Further, the current signal of motor links to each other with the feedback signal input terminus of described motor control unit by the current feedback module.
Described motor control unit is PLC.
Advantage of the present utility model is: this equipment can directly be rooted in widely used various PLC Controlling System at present.At processing requirements different in the converter tapping process of falling the stove, can realize can satisfying normal tapping processing requirement to controling effectively motor speed, turning angle, opening time, can realize the function protected again, avoid occurring molten steel and sprinkle the accident that.This technology can adapt to the process for making requirement fully, and the bold and vigorous steel accident of having stopped fully in the tapping process that human factor causes takes place, and has guaranteed safety in production to greatest extent.

Fig. 2 is a concrete operation method logic diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments equipment of the present utility model is described in further detail:
A kind of converter tapping control device shown in the drawings, it comprises the motor of controlling converter inclining, wherein, described motor is connected with the signal output part of motor control unit, transmitter is connected with the analog quantity input terminus of described motor control unit by the analog quantity load module, and power module is connected with the power input of described motor control unit; Instruction input module links to each other with the switch signal input terminus of described motor control unit; The current signal of motor links to each other with the feedback signal input terminus of described motor control unit by the current feedback module.
Motor control unit described in the technique scheme is PLC.
The utility model is judged next step action request of converter inclining by the converter actual position value, and undesirable actuating signal is shielded automatically or limits.
The utility model in use, power module is powered to motor control unit, sensor sensing converter tilt angles degree inserts motor control unit to the signal of converter tilt angles degree by the analog quantity load module then; Instruction input module is used for to motor control unit conveying startup and ceases and desist order, and operator control motor control unit according to the processing requirement of converter tapping by instruction input module; The work of motor control unit control motor, this motor is used to provide the power of fascinating of converter, and its current signal feeds back to motor control unit by the current feedback module.
Below in conjunction with accompanying drawing concrete operation method of the present utility model is described in further detail.1, tapping prepare control: when fascinating beginning, detect the given direction of fascinating and be reverse (being tapping process), judge whether current turning angle prepares angle less than tapping, as "No", the sequence of control that fascinates does not move, converter as "Yes", detects current converter inclining angle by the current given speed operation of fascinating; Change then and whether judge the present speed set-point,,, less than the tapping angle at the end,, press the operation of given speed limits value, arrive up to stop sign as "Yes" up to stop sign arrival turning angle by actual given speed operation as "No" greater than limits value; 2, tapping process control: when operation, detect judgement behind the said process and whether press the limits value continuous working period greater than 2.5 seconds, as "No", continue to judge by above-mentioned whether current turning angle arrives up to stop sign less than tapping preparation angle and the operation of program loop thereafter, as "Yes", send the intermediate stop signal, wait for next time and fascinate order; 3, tapping finishing control: detect the given direction of fascinating and be reverse (being tapping process), judge that then current turning angle whether less than the tapping angle at the end, as "No", changes and judges that present speed is given whether greater than limits value, carry out above cycle criterion, as "Yes", change and judge whether the given direction of fascinating is reverse (being tapping process), as "No", continuation normally moves by above-mentioned given speed and direction, as "Yes", send the terminal point stop sign, tapping process finishes.
Technique scheme, at the processing requirement of converter tapping process, to tapping prepare, tapping process, tapping finishes the different control of design, and the technological process of different process is realized controls such as speed limit, crawl, parking respectively.Even when misoperation appears in operator, sequence of control also will limit output or block output to realize the control protection of the converter tapping process of falling the stove.
According to practical production experience, in tapping process, for shortening smelting cycle, converter is prepared the position for fascinating at full speed from zero-bit to tapping; Arrive tapping and prepare the position, gush out from fire door, prepare the position in tapping and should pause slightly for avoiding molten steel occurring; Tapping begins to have gone out process to molten steel, and fascinating should be at a slow speed, the crawl operation; Tapping is sprinkled into the slag road for avoiding slag after finishing, and fascinates to limit no longer to allow action downwards.
