Embodiment
Below in conjunction with accompanying drawing specific embodiments of the invention are described further:
1, molten iron weighing operations management and information transfer device: molten iron weighing operations management of the present invention and information transfer device are the standard weighing execute-in-place dishes that four types of band intelligent controllers are set by different function requirements in ironmaking, steel-making, iron foundry (shop) respectively: the other molten iron weighing execute-in-place of track scale A dish 1, one in each iron mouth; Cast house platform molten iron weighing execute-in-place B dish 2, one in each iron mouth; The regional molten iron weighing execute-in-place C that makes steel coils 3, one of each steelshop; Cast iron unit room molten iron weighing execute-in-place D dish 4, one of each cast iron unit room.Each coils quantity type and disposes as required.And on the other molten iron weighing execute-in-place of track scale A dish 1 and cast house platform molten iron weighing execute-in-place B dish 2, alarm lamp, action button etc. both be set, the giant-screen alphabetic character also is set to be shown, make text prompt directly perceived by signals collecting and logic determines to the molten iron weighing process, pilot operationp person step by step, reasonable operation, even the operator is not in time by prompting operation, non-key step also can change next step over to automatically, reduce the misoperation rate, the reliability that improves the molten iron weighing device is had great improvement.
Molten iron weighing information management server (band industrial data storehouse) 5 is collected all iron mouths of this blast furnace overall process information of tapping a blast furnace, to monitoring in real time such as blast furnace casting amount, each iron mouth duty; The server data database data receives packet+molten iron by molten iron and uses packet to merge as the subject term bar with hot-metal bottle number to form, carry out record to the blast furnace casting process and to hot-metal bottle 6 behaviours in service, add up hot-metal bottle 6 access times, time, slag residual quantity etc. at any time; In addition when existing a plurality of converters and volume inequality, corresponding hot-metal bottle 6 receives iron water amount and difference must occur, and server is discerned automatically according to hot-metal bottle search call setup parameter, promoted blast furnace holistic management level, for blast furnace production provides partial data.
Data transfer between the execute-in-place dish does not need the network physical transmission medium, and the unique identification card that relies on hot-metal car transportation driver to carry is that carrier carries out blast furnace and makes steel transmission regional, pig machine number of chambers certificate, but the mode difference that different zones reads and writes data.Insertion identification snapped into the other molten iron weighing execute-in-place of track scale A dish 1 after hot-metal car sailed into and stops accurate position under the blast furnace iron notch, at first input is about to receive the hot-metal bottle 6 codings numbering of molten iron as unique identification, need not increase equipment finishing hot-metal bottle number reads, after hot-metal bottle 6 reception molten iron reach the quantitative setting value of molten iron, automatically form molten iron reception packet and write to identification card, short word joint data splitting bag only sends the key message that needs.After hot-metal ladle and carriage sails steelshop into, insert identification and snap into the regional molten iron weighing execute-in-place C dish 3 of steel-making, read all hot-metal bottle molten iron reception information on this hot-metal ladle and carriage, under the normal condition, the converter computer system sends confirmation signal after receiving information, interpolation is simultaneously taken out identification card after writing molten iron use packet.Under the improper situation, the transmission part did not receive hot-metal bottle 6 signals after information was received by the converter computer system, a while interpolation writes the molten iron reception packet that the molten iron that will receive uses the packet reservation not receive, and hot-metal car can remove other steelshop or cast iron unit room, consumes up to molten iron to finish.Cast iron unit room molten iron weighing execute-in-place D coils 4 principle of work and steelshop and makes steel regional molten iron weighing execute-in-place C and coil 3 similarly, just must receive hot-metal bottle 6.Hot-metal ladle and carriage is got back under the blast furnace iron notch again after reapposing slack tank, read hot-metal bottle molten iron use last time packet information by track scale side molten iron weighing execute-in-place A dish 1 and be directly passed to molten iron weighing information management server (band industrial data storehouse) 5, cast house platform molten iron weighing execute-in-place B dish 2 is finished molten iron reception weighing process operation control on the cast house platform.
It is to finish receiving the back at molten iron to form that molten iron receives packet, it is to form when molten iron is really consumed that molten iron uses packet, packet contains these contents respectively, is equivalent to point-to-point intelligence " manifest " formula information transmission mode and has thoroughly avoided the information transmission difficult problem that complicated logistics transmission ﹠ distribution process is brought.Using this information writes, reads mode and realized that also the molten iron between accessible many blast furnaces receives again.The present invention has not only satisfied molten iron " a jar on earth " technological process requirement, also is applicable to the especially large-scale steel plant in ordinary steel ironworks complicated logistics transmission ﹠ distribution information mutual communication.
2, the mode of operation of molten iron weighing management devices: the mode of operation of molten iron weighing management devices is by the on-the-spot Word message prompting of molten iron weighing management devices, sail state into according to the detected weight signal animation display of weighing track scale hot-metal car, the coding numbering on the hot-metal ladle and carriage is imported in the back prompting of stopping, this hot-metal ladle and carriage of storage gross weight sends hot-metal ladle and carriage and is ready to signal after the automatic average processing.Molten iron dynamically shows hot-metal bottle general assembly (TW) and molten iron nt wt net weight after flowing into hot-metal bottle; Trigger molten iron simultaneously and receive timer, record taps a blast furnace process constantly, adds up to tap a blast furnace process time.By to weight of molten iron differential calculation molten iron inbound pacing, according to the quantitative setting value of molten iron, extrapolate this hot-metal bottle and finish receiving Estimated Time Remaining again.
Automatically the preceding quantitative setting value of molten iron of this hot-metal bottle of search call behind the input hot-metal bottle number, and by roughly 90% calculate generate molten iron quantitatively before setting value.The quantitative setting value of molten iron, the quantitatively preceding setting value of molten iron also can changes once more on picture.Reach molten iron quantitatively before setting value, the quantitative setting value of molten iron scene send sound and light alarm, when another line hot-metal ladle and carriage is ready to, the mouth commutation is slipped in the prompting swing.
Swing slide mouth commutation position signal arrives, and this hot-metal bottle molten iron receiving course is finished.The hot-metal bottle gross weight stops computing, and the molten iron inbound pacing stops to calculate.Central Control Room sends the off-line confirmation signal, and hot-metal car weight decline pace of change thinks that hot-metal car begins off-line greater than setting value with to hang down gross weight outer 50%, hangs down 95% and thinks that off-line finishes.After waiting for that next empty hot-metal ladle and carriage sails into, above-mentioned weighing master routine turns round again.
After the shutoff of iron mouth was finished, trough noresidue molten iron was pressed the conclusion button that taps a blast furnace, and stopped molten iron and received timing, stopped to write down the process time that taps a blast furnace.The time of tapping a blast furnace that does not reach the quantitative setting value of molten iron and calculate by the molten iron inbound pacing, whether needed secondary receive molten iron signal, judged by Central Control Room if sending in short-term; Operating personnel think to send in the quantitative setting value error range of molten iron does not need secondary to receive the molten iron confirmation signal; Operating personnel think to send outside the quantitative setting value error range of molten iron needs secondary to receive the molten iron confirmation signal.Secondary receives molten iron inquiry picture and jumps out, and by retrieving for examination other iron message breath, tentatively judge the back: first telephone contact is consulted, and selected again secondary receives the molten iron position; Or Web broadcast mode request between blast furnace, wait for that other blast furnace replys, determine that again secondary receives the molten iron position; A molten iron receives information and calls between blast furnace, directly is transferred to secondary and receives the molten iron position, finishes the secondary molten iron and receives.If need to confirm secondary to receive molten iron, but do not have secondary to receive the molten iron record, be considered as defective molten iron, should be by the production scheduling special processing.
Receive in the molten iron process,, judge whether weighing sensor has damage by the hot-metal bottle wheel being divided into the weighing A that puts and the weight operational analysis of B section; General assembly (TW) equals A+B under the normal condition.As A+B＞2A, B＞A, A section pressure head damages damage; A+B＞2B, A＞B, B section pressure head damage, and general assembly (TW) equals 2A or the 2B big value after relatively under the improper situation.Automatic zero set (AZS) when no hot-metal ladle and carriage is parked.
Omnidistance by the sequencing that occurs to operating process, alarm on picture has only and just can send this hot-metal bottle molten iron receiving course finish signal after basic step is finished.If the secondary molten iron receives, just can send this hot-metal bottle molten iron receiving course after also must finishing and finish signal by secondary molten iron reception basic step.
3 information packet constitute form and transmission condition: hot-metal bottle receives molten iron end signal to Central Control Room and judges that also Central Control Room sends confirmation signal, treats that the weighing process finishes the back and sends " molten iron reception packet ".Molten iron receives data packet format: hot-metal bottle number+high heat (batch) number+iron slogan and weighing line code+hot-metal bottle gross weight+molten iron net weight+reception molten iron the start time+reception molten iron concluding time+secondary sign indicating number+effect sign indicating number that taps a blast furnace.Data are by writing the card device identification card that writes direct.
When receiving molten iron as the need secondary, do not form " molten iron reception packet ", a molten iron receives data and can call between blast furnace.After secondary reception molten iron is finished, send packet in a manner described.
After hot-metal bottle is made steel or pig machine receives allocation and transportation and finish, send " molten iron use packet ".Molten iron uses data packet format: hot-metal bottle number+steelshop or iron foundry (shop) numbering+hot-metal bottle gross weight+molten iron net weight+hot-metal bottle send to time+the effect sign indicating number.Data are added on molten iron and receive after the packet by writing the card device identification card that writes direct.
Hot-metal ladle and carriage is got back to the blast furnace ironmaking zone before receiving molten iron again, use in the packet information to read in molten iron, be directly passed to the molten iron weighing information management server, and wipe " molten iron reception packet " and " molten iron use packet ", receive information so that store new molten iron, beginning next round molten iron receives, uses writing of data.
Identification card is divided into upper half and bottom half, and each dualization of packet record (promptly upper half and bottom half each once) prevents the Card read/write mistake; According to maximum hot-metal bottle transportation quantity, will divide erasable information record segment, byte number is not less than " molten iron reception packet " and " molten iron use packet " total volume; Identification card has also been opened up the fix information storage area in addition.
It is to finish receiving the back at molten iron to form that molten iron receives packet, it is to form when molten iron is really consumed that molten iron uses packet, packet contains these contents respectively, is equivalent to point-to-point intelligence " manifest " formula information transmission mode and has thoroughly avoided the information transmission difficult problem that complicated logistics transmission ﹠ distribution process is brought.Using this information writes, reads mode and realized that also the molten iron between accessible many blast furnaces receives again.The present invention has not only satisfied molten iron " a jar on earth " technological process requirement, also is applicable to the especially large-scale steel plant in ordinary steel ironworks complicated logistics transmission ﹠ distribution information mutual communication.
