Dab tsi yog Cov Kev Siv Tseem Ceeb ntawm Thermocouples hauv Steel Industries?

Thermocouples yog cov cuab yeej tseem ceeb heev nrog ntau yam kev siv hauv steel sector. Cov cuab yeej ntsuas kub no zoo li lub qhov muag thiab pob ntseg tso cai rau kev tswj xyuas kom zoo thiab ua kom zoo tag nrho los ntawm cov txheej txheem nyuaj steel.
Raws li cov txiaj ntsig Seebeck-kev tsim cov hluav taws xob ntawm qhov sib txuas ntawm ob qhov sib txawv ntawm cov hlau nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias-thermocouples Lawv ua haujlwm hauv steel sectors yog raws li lub tswv yim yooj yim tab sis muaj zog. Lawv tau ua kom muaj zog thiab meej, muaj peev xwm tiv taus qhov hnyav ib puag ncig hauv kev tsim steel.
Thermocouples pom zoo siv hauv cov txheej txheem melting ntawm lwm yam. Txawm hais tias lawv yog lub cub tawg yooj yim lossis lub tshuab hluav taws xob hluav taws xob, lub tshuab ua hlau yuav tsum tau saib xyuas qhov kub thiab txias. Piv txwv li, cov cua sov muaj zog uas tsim nyob rau hauv hluav taws xob arc rauv melts khib nyiab hlau thiab lwm yam ntaub ntawv raw. Zoo tshaj 1500 degrees Celsius yog qhov kub thiab txias. Thermocouples txhob txwm tshaj tawm nyob rau hauv lub qhov cub muab cov ntaub ntawv kub ntawm lub sijhawm. Cov txheej txheem melting yuav qeeb nyob rau hauv qhov kub thiab txias heev. Tsis tiav melting ntawm tus nqi yuav ua raws li los ntawm qhov no, ua inclusions nyob rau hauv cov hlau molten. Cov kev sib ntxiv no tuaj yeem yog qhov tsis xws ntawm cov khoom siv hlau tiav, yog li cuam tshuam nws qhov zoo thiab lub zog. Nws zoo li sim tsim ib qho kev sib tov sib xyaw nrog qee cov ntsiab lus tseem tshuav hauv cov pob khoom. Hloov pauv, qhov kub thiab txias heev tuaj yeem ua rau oxidation ntau dhau ntawm cov hlau. Tsis xav oxides tsim los ntawm cov tshuaj tiv thaiv ntawm cov hlau molten nrog cov pa oxygen nyob rau hauv lub cub tawg ib puag ncig yuav cuam tshuam cov yam ntxwv ntawm cov hlau. Thermocouples lav tias qhov kub melting poob rau hauv qhov zoo tagnrho, yog li ua kom zoo thiab huv si ntawm cov hlau.
Thermocouples kuj tseem ceeb heev nyob rau hauv cov txheej txheem refining. Rau ladle refining, piv txwv li, qhov ntsuas kub yog qhov tseem ceeb ntawm kev tshem tawm cov kab mob xws li phosphorous thiab sulfur. Cov txheej txheem tshuaj kub-rhiab heev ua rau cov hlau ua kom huv. Los ntawm kev ntsuas lub ladle qhov kub thiab txias, cov thermocouples cia cov neeg ua haujlwm hloov cov kev kho kom zoo. Yog tias qhov ntsuas kub tsis raug tsis raug, cov txheej txheem kho kom zoo yuav tsis ua tiav. Nws zoo li kev sim tshuaj rhiab heev qhov twg qhov kub ntawm qhov kev hloov pauv me tshaj cuam tshuam rau qhov tshwm sim. Thermocouples pab tsim cov hlau nrog txo qis impurity, yog li txhim kho nws qhov zoo thiab tsim nyog rau ntau yam kev siv los ntawm kev muab cov ntaub ntawv ntsuas kub.
Xyuas kom zoo ntawm cov hlau cam khwb cia nyob ntawm cov thermocouples thoob plaws hauv txheej txheem casting. Pouring molten steel rau hauv pwm nyob ntawm qhov kub thiab txias nws nkag mus thiab solidifies ntawm. Qhov kub siab dhau lawm tuaj yeem ua rau muaj teeb meem xws li cam khwb cia khoom shrinkage voids los yog tawg. Nws zoo li cov dej npau npau sai sai rau hauv lub thawv; Kev ua kom txias tsis sib xws tuaj yeem tawm qhov khoob. Ntawm qhov tod tes, yog tias qhov ntsuas kub tsawg dhau, cov hlau tsis tuaj yeem ntws txaus kom puv cov pwm, ua qhov tsis zoo. Thermocouples nyob rau hauv lub kaw lus casting los yog ze rau cov pwm yuav taug qab qhov kub thiab txias thaum lub sij hawm pouring thiab solidification. Qhov no tau lees paub tias cov hlau khov kho kom raug thiab cov txiaj ntsig cam khwb cia yog qhov zoo heev los ntawm kev tso cai rau kev hloov pauv mus rau qhov nrawm nrawm thiab txias txias ntawm pwm.
Lwm thaj chaw uas cov thermocouples yog qhov tsis tseem ceeb hauv cov hlau yog cov txheej txheem kho cua sov. Txhawm rau tso qhov nro sab hauv thiab ua kom ductility, cov hlau yog rhuab mus rau qhov ntsuas kub thiab maj mam txias hauv annealing. Annealing yuav tsum muaj qhov txwv rau qhov kub thiab txias. Thermocouples tso cai rau kev tswj xyuas cov cua sov thiab cua txias los ntawm kev ntsuas qhov kub thiab txias thoob plaws hauv kev ua haujlwm no. High hardness nyob rau hauv cov hlau yog tau nyob rau hauv quenching los ntawm kev siv ib tug ceev ceev cov txheej txheem Qhov kub ntawm qhov txo yog ib qho tseem ceeb heev, li no thermocouples lav tias nws ntog nyob rau hauv qhov tsim nyog ntau yam. Yog tias qhov kev kho cua sov qhov ntsuas kub tsis raug, cov hlau tsis tuaj yeem muaj cov yam ntxwv tsim kho. Zoo li kev kho qhov ntsuas, qhov ntsuas kub me ntsis tuaj yeem cuam tshuam loj rau kev ua haujlwm steel kawg.
Tsis tas li ntawd feem ntau siv hauv kev tsim cov hlau tam sim no yog cov txheej txheem nruam casting, uas cia siab rau cov thermocouples. Hauv kev nruam nruam, qhov kub ntawm cov hlau molten nyob rau hauv tundish thiab thoob plaws hauv cov txheej txheem solidification hauv pwm yuav tsum tau nyob rau hauv kev soj ntsuam. Cov ntaub ntawv kub uas yuav tsum tau los ntawm cov thermocouples guarantees ib tug tas li thiab nruam casting txheej txheem. Txhua qhov kub hloov pauv tuaj yeem cuam tshuam qhov zoo ntawm cov hlau tsis tu ncua; Thermocouples pab kom paub tseeb lub sijhawm thiab kho cov teeb meem zoo li no.
Piv txwv li, thermocouples yog ib qho tseem ceeb heev nyob rau hauv steel sector rau ntau lub hom phiaj. Kev tswj xyuas qhov zoo thiab cov yam ntxwv ntawm cov hlau yog nyob ntawm lawv los ntawm melting thiab refining mus rau casting thiab kev kho cua sov. Lub hauv paus ntawm kev ua tau zoo thiab kev tsim cov hlau zoo yog lawv qhov ntsuas qhov ntsuas kub, uas yuav pab cov hlau ua kom tau raws li cov kev xav tau ntawm ntau qhov kev lag luam nyob ntawm cov khoom siv hloov tau.
