Nyob rau hauv kev tsim cov tooj liab matte, lub converter tshuab thiab tooj liab refining yeej yog tib yam.
1) Lub tshuab hluav taws xob
Vim yog qhov kub thiab txias hauv lub reactor, lub siab ceev cua ntws sib xyaw nrog yaj erodes thiab corrodes lub reactor ntauwd, yog li cov phab ntsa ntawm lub reactor ntauwd yuav tsum tau ua los ntawm cov khoom zoo refractory uas yog resistant rau kub, yaig thiab corrosion. Tam sim no, electromolten magnesia chrome cib yog siv. Txhawm rau tiv thaiv electromolten magnesia chrome cib, ob peb txheej ntawm kab rov tav tooj liab phaj dej tsho yog sandwiched nyob rau hauv cib masonry, dej-txias tooj liab yeeb nkab los yog ntsug tooj liab phaj dej tsho yog teem nruab nrab ntawm lub cib masonry thiab lub plhaub, thiab zoo tib yam magnesia chrome. cib yog siv rau masonry nyob rau sab saum toj thiab sab sauv qis-kub cheeb tsam ntawm cov tshuaj tiv thaiv ntauwd. Qhov kev sib txuas ntawm cov reactor ntauwd thiab sab saum toj ntawm cov sedimentation tank (ib qho kev sib txuas ntawm lub tank sedimentation thiab cov flue nce) yog raug rau kev yaig thiab muaj zog corrosion ntawm high-temperature yaj thiab cov cua kub uas muaj plua plav. , thiab hauv ob sab phlu yog yooj yim puas, yog li cov qauv ntawm cov finned tooj liab raj nrog refractory castable los yog tooj liab tes tsho nrog high-zoo magnesium-chrome cib feem ntau yog siv.
Lub luag haujlwm tseem ceeb ntawm lub tank sedimentation yog ua kom tiav cov tshuaj tiv thaiv slagging thiab precipitate cov yaj yaj (qhov twg cov slag thiab matte yog sib cais). Lub sedimentation tank slag kab, tshwj xeeb tshaj yog nyob ze ntawm phab ntsa thiab kawg phab ntsa slag kab nyob rau hauv qis ib feem ntawm cov tshuaj tiv thaiv ntauwd, yog heev eroded los ntawm high-kub yaj. Feem ntau, ntxiv rau cov ntaub ntawv zoo xws li cov tshuaj ua ntej magnesia chrome cib thiab sib txuas ncaj qha magnesia chrome cib, cov khoom no kuj tau nruab nrog cov kab rov tav tooj liab dej tsho, txias cov yeeb nkab tooj liab thiab inclined tooj liab dej tsho kom ntev lawv lub neej kev pab cuam. Sab saum toj ntawm sedimentation tank kuj yog ib feem tiag ntxuav los ntawm high-temperature airflow. Feem ntau, nyob rau hauv cov kev taw qhia axial, lub "H" hom dej-txias beam nrog fin dej-txias tooj liab yeeb nkab yog teem nrog refractory castable, thiab cov dej txias yog sandwiched nyob rau hauv lub sab saum toj cib ntawm lub cub tawg los tiv thaiv lub axial deformation ntawm qhov chaw. tank saum.
Tam sim no, txoj kev loj hlob ntawm lub qhov cub hluav taws xob yog qhov loj dua, thiab nws pom tseeb tias lub qhov cub muaj qhov xav tau ntau dua rau cov khoom siv refractory, thiab cov khoom siv refractory yuav tsum tau ua raws.
