Cov nyhuv ntawm cov ntaub ntawv refractory thiab thermal rwb thaiv tsev cov ntaub ntawv ntawm hluav taws xob cua sov alloys
Nyob rau hauv lub tshuab hluav taws xob muaj hluav taws xob, txhawm rau txhim kho cov hluav taws xob cua sov thiab tiv thaiv kom tsis txhob deforming ntawm qhov kub thiab txias, nws yog ib qho tsim nyog yuav tsum tau siv cov khoom siv rov qab thiab kev txhawb nqa los ntawm cov khoom siv refractory. Qee cov khoom siv hluav taws xob cua sov ntawm cov khoom siv hauv tsev tau ncaj qha ua cov hmoov oxide. Lub sijhawm no, qhov chaw ntawm cov hluav taws xob cua sov alloy yuav ncaj qha mus cuag cov khoom siv refractory, thiab cov tshuaj tiv thaiv lub cev thiab tshuaj yuav tshwm sim ntawm qhov kub thiab txias, uas yuav ua rau cov hluav taws xob cua sov. Cov khoom siv rwb thaiv tsev yog cov khoom siv tseem ceeb los txo cov cua sov. Nyob rau hauv cov xwm txheej tshwj xeeb, kev sib cuag ntawm cov khoom siv rwb thaiv tsev nrog cov hluav taws xob cua sov yuav ua rau cov hluav taws xob cua sov.
Cov lus qhia rau kev siv mica hluav taws xob cua sov coil:
1. Cov kab hluav taws xob yog muab tso rau sab nraum cov cua sov txheej thiab txheej rwb thaiv tsev, thiab lub plhaub yuav tsum tau zoo hauv av;
2. Khaws rau hauv qhov chaw qhuav.
Refractory thiab rwb thaiv tsev cov ntaub ntawv hnav
Thaum cov txheeb ze txav tau tshwm sim ntawm qhov chaw ntawm cov khoom cua sov thiab cov khoom txhawb nqa refractory, cov yeeb yaj kiab oxide tiv thaiv ntawm qhov chaw ntawm cov khoom yuav raug hnav. Yog vim li cas rau cov txheeb ze txav yog tias cov hluav taws xob cua sov alloy nthuav thaum rhuab thiab sib cog lus thaum txias. Txawm hais tias qhov tshwm sim no tsis cuam tshuam nrog cov ntaub ntawv refractory, yog tias tsim nyog thiab kho kom raug, cov nyhuv no yuav raug txo.
Magnesium pas nrig yog lub npe nrov ntawm magnesium anode, tseem hu ua anode magnesium thaiv, uas yog siv los tiv thaiv corrosion ntawm hlau sab hauv tank thiab muag dej zoo. Hauv kev siv TISCO lossis manganese steel hlau liner, electrochemical anticorrosion sacrificial anode tiv thaiv txoj cai ntawm cov hlau hauv dej yog siv, thiab cov pas nrig magnesium yog siv los ua cov anode thiab cov hlau liner yog siv cathode. Nyob rau hauv no txoj kev, ib tug galvanic cell yog tsim ntawm lub cathode thiab lub anode los ntawm ib tug conductive dej nruab nrab. Lub anode ntawm lub roj teeb, lub magnesium pas nrig, yog corroded thiab noj, thaum lub cathode, hlau puab conductor, yog tiv thaiv.
Arc cua sov kuj yog ib qho kev siv cua sov rau cov cua sov hluav taws xob. Txhawm rau kom muaj kev ruaj ntseg ntawm lub arc thaum lub sij hawm arc cua sov, thaum lub arc tam sim no hla xoom, tus nqi tam sim no ntawm qhov hluav taws xob hluav taws xob ntau dua li tus nqi arc voltage. Nyob rau tib lub sijhawm, txhawm rau txhawm rau txo qhov luv luv tam sim no, qee tus nqi ntawm kev tiv thaiv yuav tsum tau txuas nrog hauv series hauv lub zog hluav taws xob.
