Kev siv lub tshuab nqus oxygen txhawm rau txo qis kev siv zog ntawm ladle preheating

Wu Steel Works muaj ob lub rooj cob qhia, ib qho kev ua haujlwm hlau ua haujlwm thiab qhov thib ob ua haujlwm tsim steel hlau. Qhov thib ob steelmaking rhiav tsim cov hlau zoo tib yam, thiab thawj steelmaking rhiav feem ntau tsim cov khoom me me ntawm cov qib hlau xws li cov hlau tshwj xeeb. Cov txheej txheem ntau lawm suav nrog cov hlau kub sibtham ua haujlwm, hloov pauv, thiab RH. Degassing thiab nruam casting tsim txog 20 qhov cub ntawm hlau nchuav hauv ib hnub.

  Lub tsev noj cov roj hnyav roj rau ladle preheating hauv thawj qhov kev tsim cov hlau ua yog ntau dua li qhov tau hais hauv kev tsim cov hlau ua haujlwm thib ob. Yog tias thawj lub rooj cob qhia hlau yog 100, tom qab ntawd lub rooj zaum ua haujlwm hlau thib ob yog 6.8. Yog li no, txo cov roj ntau hauv cov roj hauv qhov cub hluav taws kub preheating hlawv ntawm lub rooj sib tsoo steel hlau tau dhau los ua qhov teeb meem tseem ceeb. Txhawm rau kom txo qis siv lub zog ntawm ladle preheating, Wu Iron & Steel Institute ua kom paub cov pa hlawv lub zog.

  Raws li kev sib piv ntawm kev sib xyaw muaj peev xwm thiab cov yam ntxwv sib xyaw ua ke ntawm lub ntshiab oxygen burner thiab lub tshuab cua, nws tuaj yeem pom tau tias thaum cua siv cov pa, cov pa tsis haum (suav txog 79% ntawm huab cua) yog tshuab hauv, yog li cov nplaim taws ua kom sov yuav ua rau qis qis. , Ua kom cov roj tsheb ntxiv thiab nce qhov cua sov poob. Thaum siv cov pa hluav taws kub ntshiab-roj hlawv, txij li cov hlawv tsuas yog siv cov pa uas yuav tsum muaj rau kev sib txuas, cov nplaim taws kub kom sib ntxiv tau nce mus rau 3000 ℃, thiab cov pa hluav taws xob tau txo kom tsawg, yog li cov cua kub yuav raug tshuaj lom thiab cov cua sov zoo tuaj yeem tau ntxiv. Txo cov kev noj roj ntau thiab txo nqi roj.

  Cov cua kub muaj peev xwm xav tau los ntawm cov pa ntshiab huv lub cev yog tib yam li ntawm cov pa hluav taws, thiab nws yuav tsum muaj peev xwm ua kom sov qhov kub ntawm qhov hluav taws xob refractory lub teeb ntawm tus menyuam txij li 600 ° C mus txog 1000 ° C hauv txog 20 feeb. Thaum cov pa hluav taws kub siv, qhov ntau ntawm cov khoom sib txuas yog 520L / teev, thaum lub tshuab hluav taws xob ntshiab-roj hlawv kom ua tiav cov cua sov zoo, yog li qhov ntau ntawm kev sib tsoo ntau yog 350L / teev, uas yog txaus.

   Thaum cov pa hluav taws kub siv, qhov muaj peev xwm ua kom sov yog 20 ° C / min thaum cov roj hnyav hlawv yog 450L / teev, thiab thaum siv cov pa hlawv cov pa huv, cov cua sov ua kom zoo dua qub, thiab tus nqi ntawm cov roj hnyav hlawv yog 200 ～ 250L. Nyob rau hauv rooj plaub ntawm / hr, tib qhov muaj peev xwm cua sov ua haujlwm raws li cov cua kub tuaj yeem tau txais.

Tom qab qhia txog lub tshuab pa ntshiab huv, kev siv zog ntawm kev txhim kho kom zoo dua. Yog li no, qhov kub ntawm qhov nce ntawm tus ntaiv refractory ua ntej txhaws rau lub molten steel yog li hauv qab no. Tom qab ua kom sov li 15 feeb, qhov kub ntawm qhov refractory yuav ncav cuag 75 ° C, thiab tom qab cua sov rau 20 feeb, nws yuav mus txog 100 ° C, nws yuav mus txog 125 ° C tom qab cua sov rau 25 feeb.
   Piv nrog huab cua hlawv, qhov ntsuas kev noj ntawm cov roj nyhav tau txo los ntawm 46% tom qab lub tshuab nqus cov pa oxygen huv, thiab lub zog txuag tau zoo heev.

Raws li kev sib piv ntawm cov roj nqi ua ntej thiab tom qab txhim kho lub roj hlawv, thaum cov roj ntshiab huv-roj hlawv lub tshuab siv, txawm hais tias tus nqi ntawm cov pa tau nce siab, cov nqi roj tag nrho tau nqis los ntawm kwv yees li 37%. Tib lub sijhawm, nws txo CO2 pa paug thiab pab txhawb kev txhim kho ib puag ncig.
