Lub tshuab hluav taws xob sib xyaw yog ib qho cuab yeej uas khaws cov hlau molten ib ntus ntawm lub tshuab hluav taws xob thiab lub tshuab hloov kom muaj qhov sib npaug ntawm cov khoom siv hlau molten los ntawm lub tshuab hluav taws xob thiab cov kev xav tau ntawm lub tshuab hloov. Lub luag haujlwm tseem ceeb ntawm lub tshuab hluav taws xob sib xyaw yog khaws qhov kub thiab muaj pes tsawg leeg ntawm cov hlau molten thiab cov hlau tsis sib xws. Txhawm rau kom ntseeg tau tias qhov kub thiab txias thaum tapping, qhov sib tov rauv feem ntau yog nruab nrog lub tshuab hluav taws xob rau cua sov. Lub tshuab hluav taws xob sib xyaw ua ke feem ntau muaj lub tshuab ua kom sov lub cev, lub qhov cub npog qhib thiab kaw mechanism, thiab lub tshuab ua kom sov lub cev tilting. Lub qhov cub lub cev yog tsim los ntawm lub cub tawg, lub nplhaib txhawb nqa, lub qhov hluav taws xob hlau, lub qhov hluav taws xob hlau, thiab lub cib hauv lub qhov cub.
Ua haujlwm ib puag ncig ntawm cov hlau sib xyaw ua ke
Lub tshuab hluav taws xob sib xyaw hlau feem ntau yog siv rau lub sijhawm ntev ntawm cov hlau molten kom muaj qhov tsim nyog smelting kub. Thaum lub sijhawm ua haujlwm, qhov kub hauv qhov cub sib xyaw hlau feem ntau khaws cia ntawm thaj tsam 1350 degree, thiab lub plhaub kub ntawm lub cub tawg yog nyob nruab nrab ntawm 300 ~ 400 degree. Thaum txhaj cov hlau molten rau hauv cov hlau sib xyaw rauv, vim qhov poob loj, cov hlau molten yuav muaj qee yam kev cuam tshuam rau hauv lub qhov cub. Tsis tas li ntawd, txhawm rau tswj qhov kub ntawm cov hlau molten nyob rau hauv lub cub tawg, nws yog ib qho tsim nyog yuav tsum tau txau roj rau cov nplaim hluav taws kub, uas yuav ua rau muaj qee yam kev ntxhov siab ntawm cov khoom siv hauv ob sab phlu. Yog li ntawd, cov khoom siv hauv ob sab phlu ntawm cov hlau sib xyaw rauv yuav raug tshuaj lom neeg yaig thiab infiltration ntawm molten hlau thiab slag, nrog rau qhov kub thiab txias hloov thiab thermal stress faib rau hauv cov khoom. Tsis tas li ntawd, thaum lub qhov cub sib tov yog tilted, lub hauv ob sab phlu ntawm lub cub tawg kuj yuav cuam tshuam zoo heev los ntawm cov neeg kho tshuab yam vim lawv cov khoom zoo.
Lub tshuab hluav taws xob sib xyaw siv cov khoom siv refractory
Raws li qhov chaw ua haujlwm thiab kev puas tsuaj ntawm cov hlau sib xyaw rauv, nws tuaj yeem txheeb xyuas tau tias nws cov khoom siv rau cov khoom siv refractory yog cov khoom siv siab, muaj zog slag tsis kam, zoo thermal shock resistance, thermal conductivity tsawg, thiab kev hloov me ntsis ntawm cov kab rov ua dua. Cov khoom siv refractory siv suav nrog magnesium cib, magnesium chromium cib, siab alumina cib, av nplaum cib, thiab qee qhov refractory fillers. Nyob rau tib lub sijhawm, vim muaj qhov teeb meem ntawm kev puas tsuaj hauv zos thaum siv cov hlau sib xyaw ua ke, cov tshuaj tsuag tshuaj refractory feem ntau yog siv los kho. Cov ntaub ntawv siv yog txiav txim siab raws li qhov xwm txheej ntawm lub qhov cub hauv ob sab phlu masonry, suav nrog magnesium thiab txhuas magnesium.
