Daim ntawv thov ntawm tus pas ntsuas kub infrared hauv kev lag luam hlau thiab hlau smelting Yuav ua li cas xaiv thiab yuav tus pas ntsuas kub
Txawm hais tias qhov kub thiab txias yog nyob rau hauv qhov kev xav tau ntawm cov txheej txheem; seb qhov cub kub kub tsawg dhau lossis siab dhau; seb lub dov zeb yuav tsum tau hloov kho, los yog qhov twg nws yuav tsum tau txias. Cov ntsuas kub infrared tau saib xyuas txhua theem kom cov hlau tuav cov khoom siv hlau kom raug thoob plaws hauv kev ua haujlwm. Cov ntsuas kub infrared tuaj yeem pab txhim kho cov khoom zoo thiab kev tsim khoom, txo kev siv hluav taws xob, txhim kho cov neeg ua haujlwm kev nyab xeeb, txo qis sijhawm, thiab ntau ntxiv thaum lub sij hawm tsim cov hlau. Infrared thermometers yog tsuas yog siv nyob rau hauv nruam casting, kub moj tej tawg qhov cub, kub dov, txias dov, bar thiab hlau dov nyob rau hauv cov txheej txheem ntawm steel ua thiab manufacturing. INF infrared tus pas ntsuas kub sensor lub taub hau nrog digital circuit thiab kev sib txuas lus ob txoj kev (xws li IRCON's MODLINE5 series), tuaj yeem nqa tawm cov chaw taws teeb tswj kev teeb tsa ntawm lub taub hau sensor hauv chav tswj, kom cov haujlwm txhim kho thiab tswj tau zoo dua - qhov no yog qhov zoo heev. tseem ceeb rau emissivity hloov cov ntaub ntawv hlau yog qhov tseem ceeb tshwj xeeb. Txhawm rau tsim cov khoom lag luam zoo thiab ua kom cov khoom tsim tau, qhov ntsuas kub kom raug yog tus yuam sij rau tag nrho cov txheej txheem ntawm steelmaking. Thaum nruam casting hloov molten steel rau hauv slabs, slabs los yog billets, tej zaum yuav raug txiav los yog kaw. Kev ntsuas kub ntawm lub sijhawm tiag tiag yog qhov yuav tsum tau ua, ua ke nrog cov dej nozzles thiab kev hloov pauv ntws, txhawm rau muab cov cua txias kom zoo, txhawm rau xyuas kom meej tias cov steel billet yuav tsum muaj cov khoom siv hlau zoo heev, ua rau cov khoom zoo, ua kom muaj txiaj ntsig thiab cov cuab yeej siv tau ntev. Tus qauv ntawm lub taub hau sensor xaiv yog txiav txim siab los ntawm cov txheej txheem tsim khoom thiab qhov chaw ntawm lub taub hau sensor. Yog tias nws tau nruab rau hauv ib puag ncig hnyav thiab txoj kab ntawm qhov pom tau thaiv los ntawm cov plua plav, dej pos huab lossis chav dej, qhov kho qhov muag fiber ntau dual-xim sensor lub taub hau thiab kev ntsuas qhov ntsuas kub sib xyaw ua ke yog qhov kev xaiv zoo tshaj plaws. Yog xav tau ib daim ntawv qhia qhov kub-rau-ntug ntawm cov hlua, yuav siv tau ib kab scan infrared tus pas ntsuas kub. Hom kub dov thiab tus naj npawb thiab hom dov mills nyob rau hauv cov txheej txheem dov sib txawv nrog rau hom khoom ua tiav. Thaum lub sij hawm tag nrho cov txheej txheem ntawm cov hlau, kev ntsuas kub tsis tu ncua thiab kev hloov kho khib tuaj yeem ua kom cov khoom zoo thiab kev siv ntawm cov kab ntau lawm, thiab tuaj yeem zam kev poob qis. Ib qho kev ua haujlwm siab ntawm ob lub ntsuas kub los yog kab-scanning infrared tus pas ntsuas kub nrog lub wavelength ntawm 1 hli (rau cov slabs dav) tuaj yeem ntsia tau ua ntej descaler thiab roughing Teem lub roughing zeb tsis raws li. Lub steel billet yog tsis tu ncua txias ua ntej nkag mus rau lub dov zeb. Yog tias cov kab ntau lawm tsis ua haujlwm rau ib lub sijhawm, lub steel billet yuav txias dua ua ntej rov pib dua. Yog li ntawd, cov yob yuav tsum tau teeb tsa kom them nyiaj rau cov kev hloov pauv hauv qhov kub thiab txias. Cov yob tuaj yeem raug teeb tsa los ntawm tus neeg teb xov tooj, lossis lub ntsuas kub infrared tau teeb tsa rau pem hauv ntej ntawm txhua lub tshuab dov, thiab lub tshuab dov tuaj yeem teeb tsa tau. Qhov no ua kom lub zeb raug teeb tsa kom raug. Txhawm rau tshem tawm qhov cuam tshuam ntawm chav thiab plua plav ntawm qhov ntsuas qhov ntsuas kub hauv qhov chaw tswj qhov cua txias, lub ntsuas kub ntawm cov xim colorimetric yog siv los ntsuas qhov ntsuas kub kom raug txawm tias lub zog ntawm lub hom phiaj raug thaiv los ntawm 95 feem pua. Thaum lub sij hawm kub dov, feem ntau txias steel phaj yog dov rau hauv coils los ntawm coilers rau thauj mus rau txias dov los yog lwm yam khoom siv. Txhawm rau kom lub laminar txias cheeb tsam txias kom zoo, ntsuas qhov kub thiab txias yog xav tau ntawm lub coiler. Qhov kub ntawm lub sijhawm no yog qhov tseem ceeb vim tias nws txiav txim siab seb cov hlau puas txias kom zoo ua ntej yuav coiled.
Txwv tsis pub, qhov txias tsis tsim nyog yuav hloov cov khoom siv hlau ntawm cov hlau thiab ua rau khib nyiab. Txij li thaum lub ntsiab lus no yog txias dua thiab cov hlau tau taug kev ntawm 75 mus rau 100 ft / s, yuav tsum muaj lub ntsuas cua kub cua sov nrog lub sijhawm teb ceev. Qee cov rolling mills coil cov hlau kub tom qab yob yob thiab xa mus rau lwm qhov ntawm cov nroj tsuag. Tom qab ntawd nws yog kub dov thiab uncoiled, xa mus kom tiav dov, txias, thiab ces re-coiled ntawm ib tug coiler. Kev ntsuas qhov tseeb thiab kev saib xyuas qhov kub thiab txias yog qhov tseem ceeb heev ntawm qhov tsis sib xws ntawm qhov kub dov vim hais tias tus neeg teb xov tooj siv qhov no los teeb tsa qhov tsis sib xws ntawm qhov kawg zeb yob. Cov coils feem ntau tsim tom qab ua tiav qhov txias, thiab cov coils raug thauj mus rau lwm qhov chaw ntawm lub Hoobkas kom txias dov lossis mus rau lwm lub hoobkas. Txias dov ua rau cov hlau mus rau hauv ib qho khoom nyias thiab flatter, qhov twg cov hlau yog dov li ntawm 94 degree los yog nyob rau hauv ambient kub. Thermometers ntsia nruab nrab ntawm txhua lub zeb tiav tso cai rau tus neeg teb xov tooj los ua kev hloov kho zeb raws li qhov ntsuas kub hloov pauv. Lwm cov txheej txheem kev kub ceev yog bar thiab hlau dov, qhov twg billets tau rov ua dua thiab xa mus rau dov rau hauv cov tuav. Tom qab no, lub bar mus los ntawm ib tug series ntawm intermediate rollings uas txheej txheem bar rau hauv ntau qhov ntau thiab tsawg. Tom qab ua tiav dov, lub bar tuaj yeem ua rau ntau pua yam khoom sib txawv. Reheating lub billet mus rau ib qho kub tsis sib xws yog qhov tseem ceeb rau tag nrho cov txheej txheem dov, raws li qhov tsis sib xws ntawm cov khoom siv hnub nyoog bar thiab nce cov khoom siv downtime rau kev saib xyuas. Paub txog cov khoom kub ntawm qhov chaw tso cai rau tus neeg teb xov tooj kho cov yob raws li qhov xav tau. Raws li cov khoom pib nkag mus rau hauv qhov chaw txias, qhov txias txias yog ceev thiab ua tib zoo saib xyuas kom ntseeg tau tias cov khoom siv metallurgical. Yog tias qhov kev tswj kom txias tsis zoo, cov khoom lag luam tsis tuaj yeem ua tau raws li cov txheej txheem specification, uas ua rau txo cov khoom tsis zoo lossis cov khoom pov tseg. Hauv qee cov txheej txheem ntau lawm, xws li kev kub ceev dov thiab vibrating nyias pas nrig lossis cov khoom siv hlau, kev ntsuas kub yog qhov nyuaj heev, thiab cov ntsuas kub infrared dual-xim tuaj yeem daws qhov teeb meem no. Thaum lub hom phiaj deviates los ntawm kev saib los yog ib feem ntawm qhov thaiv (plua plav, chav, ob qho tib si, thiab lwm yam), lub ntsuas kub dual tuaj yeem ntsuas qhov ntsuas kub kom raug. Lub qhov cub kub kub muab qhov kub thiab txias ruaj khov rau lub qhov cub tawg. Rau kev ua haujlwm nyab xeeb, qhov kub ntawm lub qhov cub kub kub yuav tsum tau saib xyuas. Tam sim no, cov thermocouples feem ntau yog siv los ntsuas qhov ntsuas kub ntawm lub vault ntawm cov qhov cub kub kub hauv kuv lub tebchaws. Vim muaj kev txwv ntawm cov thermocouple siv ib puag ncig (qhov kub thiab txias, siab siab) thiab cov qauv, nyob rau hauv kev cuam tshuam ntawm ntau yam xws li kub hloov pauv, kev co, thiab cov txheej txheem kev teeb tsa, cov thermocouple muaj lub neej luv luv, qhov ntsuas tsis ruaj khov, thiab kev kho teeb meem. . Ib qho infrared ntsuas kub tiv thaiv cov cuab yeej mob siab rau qhov ntsuas kub ntawm lub qhov cub kub kub lub qhov cub tuaj yeem hloov pauv qhov ntsuas kub ntawm thermocouple kom tsis txhob muaj ntau yam tsis zoo los ntawm txoj kev no. Cov neeg siv cov txiaj ntsig tau ua pov thawj tias cov cuab yeej ruaj khov, txhim khu kev qha thiab siv tau zoo.
