Refractory cib rau blast furnace hearth yog ib yam khoom siv raw nrog cov khoom siv hluav taws xob zoo heev, nws tuaj yeem siv tau zoo heev hauv qhov kub thiab txias, yog li nws feem ntau siv rau ntau yam kub kub kilns thiab furnaces. Yuav kom siv tau zoo dua cov cib refractory rau cov hlau ua lub tshuab hluav taws xob hluav taws xob, qhia rau txhua tus paub tias kev puas tsuaj rau daim ntawv thov ntawm refractory bricks raug kev txom nyem los ntawm.
Qhov chaw sab hauv ntawm lub smelter yog lined nrog refractory cib rau lub hearth ntawm cov hlau ua blast furnace. Nws tam sim ntawd kov lub molten steel, thiab lub refractory cib hauv ob sab phlu ntawm lub hearth yog puas los ntawm ntau yam, uas yuav tsum tau muab faib ua ob pawg: ib tug yog nyob rau hauv tag nrho cov txheej txheem ntawm hlau moj tej tawg rauv smelter, nws tus yam ntxwv yog meej thiab nruam ntsiab. , ib qho yog cov qauv tsim ntawm cov phab ntsa refractory cib. Raws li lub refractory cib chaw tsim tshuaj paus, REWELL refractory cov ntaub ntawv sim tsim ib tug zoo refractory cib zoo thiab tswj cov phab ntsa qauv ntawm refractory cib kom alleviate kev puas tsuaj rau lub refractory cib hauv ob sab phlu ntawm lub hearth thaum lub sij hawm tag nrho cov txheej txheem ntawm cov hlau ua blast furnace smelter.
Rau ib qho, muaj peb theem tseem ceeb, ib qho yog kub kub; ib qho yog ntxuav thiab abrasion ntawm cov cuab yeej siv tshuab ntawm molten steel thiab slag hlau; cov organic tshuaj corrosion ntawm cov tebchaw hauv molten steel thiab slag hlau rau hauv ob sab phlu ntawm refractory cib. Nyob rau hauv qhov kub thiab txias ib puag ncig, refractory bricks yog siv rau hauv ob sab phlu ntawm lub hearth. Yog hais tias qhov kub ntawm lub ntsiab hearth ntau tshaj qhov kev thov kub ntawm cov refractory bricks, lub refractory bricks yuav corroded; cov khoom siv kho tshuab ntawm cov hlau molten thiab slag hlau flushes lub hearth, thiab ua hauj lwm sab hauv thiab sab nraum lub hearth thaum hlau yog tapping. Lub siab yuav ua rau hnav lub hearth hauv ob sab phlu; Qhov corrosion ntawm FeO thiab MnO muaj nyob rau hauv molten steel thiab slag hlau ua rau muaj kev phom sij rau kev noj cov roj refractory cib hauv ob sab phlu. Peb theem no yog txhua yam nyuaj kom tsis txhob nyob rau hauv tag nrho cov txheej txheem ntawm smelter. Kev puas tsuaj ntawm lub hauv ob sab phlu.
