Cov cuab yeej tseem ceeb rau cov hlau tsis yog hlau smelting yog cov hlau tsis muaj hlau smelting rauv. Kawm txog qhov kev thov rau ntau yam thiab zoo ntawm cov ntaub ntawv refractory vim kev kawm txuj ci ntawm kev lag luam uas tsis yog-ferrous hlau smelting yuav tsum yog lub luag haujlwm tseem ceeb rau kev lag luam refractory kom ntev lub neej ntawm non-ferrous hlau smelting furnaces thiab nce ntau lawm.
1. Kev lag luam tooj liab smelting
Cov txheej txheem ntau lawm ntawm tooj liab yog ib qho uas muaj ntau txoj hauv kev hauv ntau yam uas tsis yog-ferrous hlau. Cov txheej txheem ntau lawm ntawm tooj liab hauv kuv lub teb chaws tsis tsuas yog suav nrog tag nrho cov txheej txheem tooj liab hauv ntiaj teb, tab sis kuj suav nrog cov txheej txheem tshwj xeeb hauv kuv lub teb chaws, xws li nyiaj smelting tooj liab txoj kev thiab oxygen hauv qab. Tshuab melting rauv.
Nyob rau hauv cov txheej txheem hluav taws kub tooj liab smelting, qhov sib txawv yog tsuas yog nyob rau hauv zus tau tej cov tooj liab matte, thaum lub converter tshuab thiab tooj liab refining yeej ib txwm zoo tib yam.
Vim yog qhov kub thiab txias hauv cov tshuaj tiv thaiv ntauwd ntawm lub qhov cub hluav taws xob, cov cua kub ceev sib xyaw nrog cov yaj erodes thiab corrodes cov tshuaj tiv thaiv ntauwd. Tam sim no, fused magnesia-chrome cib yog siv. Nyob rau tib lub sijhawm, txhawm rau tiv thaiv cov fused magnesia-chrome bricks, ob peb txheej ntawm kab rov tav tooj liab phaj dej tsho yog sandwiched nyob rau hauv lub cib masonry, thiab dej-txias tooj liab kav los yog ntsug tooj liab phaj dej tsho yog teem ntawm lub cib masonry thiab lub plhaub. , sab saum toj ntawm cov tshuaj tiv thaiv ntauwd thiab thaj chaw qis qis yog tsim nrog cov pob zeb zoo tib yam magnesia-chrome. Nyob rau hauv qhov kev sib txuas ntawm cov tshuaj tiv thaiv ntauwd thiab sab saum toj ntawm cov sedimentation tank (zoo ib yam li cov kev sib txuas ntawm cov sedimentation tank thiab nce flue), nws yuav raug erosion thiab muaj zog corrosion ntawm high-temperature yaj thiab hmoov av-laden high-temperature. airflow, thiab hauv ob sab phlu yog yooj yim puas, yog li finned tooj liab feem ntau yog siv. Cov qauv ntawm high-zoo magnesia-chrome bricks embedded yeeb nkab tamping refractory castables los yog tooj liab dej tsho.

2. Kev lag luam txhuas thiab zinc
Lead-zinc airtight blast furnace
Lead-zinc airtight blast furnace yog lub cub tawg tshwj xeeb uas smelts ob hlau lead thiab zinc tib lub sijhawm hauv ib lub cuab yeej. Nws cov yam ntxwv yog tias 800-850 ℃ cua kub yog siv rau blasting; sab saum toj ntawm lub cub tawg yog khaws cia ntawm qhov kub ntawm 1050-1100 ℃; Lub hearth ntawm cov hlau lead-zinc airtight blast furnace yog ua los ntawm magnesia cib, lub hearth yog lub tsho dej, lub cub tawg lub cev yog ua los ntawm high-alumina cib, thiab sab saum toj ntawm lub cub tawg yog knotted nrog high-alumina refractory ntaub ntawv. Lub txaj pem hauv ntej ntawm cov hlau lead-zinc airtight blast furnaces yog tag nrho cov hluav taws xob cua sov pem hauv ntej txaj, thiab lawv cov kev pab cuam lub neej yog qis dua li ntawm blast furnaces. Feem ntau yog vim slag yaig thiab scouring slag kab. Tam sim no, ob lub txhuas-zinc airtight blast furnaces nyob rau hauv Tuam Tshoj yog lined nrog chrome slag cib thiab txhuas-chromium-titanium cib feem. Txawm hais tias lub hnub nyoog ntawm lub cub tawg tuaj yeem ncav cuag ntau tshaj 1 xyoos, nws tseem qis dua lub neej ntawm cov hlau lead-zinc airtight blast furnaces. Yuav ua li cas los txhim kho lub neej ntawm lub cub hluav taws xob cua sov pem hauv ntej txaj kom phim lub neej ntawm cov hlau lead-zinc airtight blast rauv yog tus yuam sij rau kev txhim kho tus nqi ntawm cov hlau lead-zinc airtight blast furnace.
