Thaum lub sij hawm steel pouring txheej txheem ntawm lub ladle, vim lub looseness ntawm lub manifold, steel yog daig ntawm lub qis swb phaj thiab lub manifold, steel penetrates, thiab txawm ua rau steel to tshwm sim, uas cuam tshuam rau cov kev sib raug zoo thiab kev ruaj ntseg ntawm steelmaking. kev lag luam, thiab tseem cuam tshuam rau kev nyab xeeb ntawm kev tsim khoom mus rau qhov loj. Nws cuam tshuam rau qhov zoo ntawm qhov zoo ntawm cov hlau billet; Nyob rau tib lub sijhawm, vim qhov qis zawv zawg qhov sib piv ntawm zawv zawg phaj, kev noj cov khoom siv refractory ib tuj ntawm steel yog nce, thiab chav tsev nqi ntawm steelmaking yog nce. Qhov kev huam yuaj ntawm loosening ntawm lub nozzle muaj kev cuam tshuam zoo rau kev tsim khoom ib txwm muaj thiab nruam plam tus nqi ntawm cov nroj tsuag steel. Yog li ntawd, kev txheeb xyuas thiab kawm txog cov laj thawj rau kev xoob ntawm lub taub hau ntawm lub taub hau yog txoj hauv kev tseem ceeb los daws qhov teeb meem ntawm kev xoob thaum siv thiab tsim cov kev ntsuas kev txhim kho.
Longketer cov khoom muaj cov yam ntxwv ntawm siab refractoriness, zoo thermal shock kev ua tau zoo, corrosion kuj, yaig kuj, me me txoj kab uas hla expansion, thiab ntev kev pab cuam lub neej.
Cov khoom lag luam Longketer muaj cov khoom siv hluav taws xob txaus thiab thermal poob siab, thiab cov khoom lag luam muab los ntawm Longketer suav nrog ntau yam khoom muaj kev nyab xeeb thiab txhim khu kev qha refractory.
Longketer yog lub tuam txhab ua lag luam hauv kev tsim cov kais dej rau cov hlau thiab cov hlau tsis muaj hlau. Ntev Keter yog lub hauv paus hauv Shandong, Tuam Tshoj, thiab nrog ntau tshaj 12 xyoo ntawm kev txawj ntse nyob rau hauv daim teb no, nws spouts yog lub siab tshaj plaws kev ntseeg siab thiab zoo.
