Thaum ntau cov khoom cua sov-hom qauv siv rau kev ua haujlwm hauv chaw lag luam, lawv feem ntau suav hais tias yog cov khoom lag luam hluav taws xob. Cov qhov cub muaj cov khoom lag luam suav nrog cov khoom siv refractory, cov khoom siv hlau thiab lwm yam khoom siv tsis yog xim hlau, nrog rau kev sib txuas ntawm cov khoom siv hlau thiab cov khoom siv tsis yog xim, thiab txawm tias siv rauv taws. Hauv cov haujlwm niaj hnub, kev lag luam hauv qhov cub tau siv dav hauv cov txheej txheem tseem ceeb ntau lawm txheej txheem cov tshuab hauv metallurgy thiab lwm qhov chaw ua lag luam.
1. Muaj cov cua sov:
Cov cua sov muaj hluav taws xob yog cov lus siv dav dav rau cov khoom siv tshwj xeeb uas siv los hloov cov duab lossis cov yam ntxwv ntawm cov khoom hauv cov haujlwm hauv kev lag luam. Nws yog qhov khoom siv tsis tseem ceeb rau hauv kev ua haujlwm hauv kev lag luam. Hauv kev ua xim hlau, tshuaj lom neeg, cov hlau tsis zoo, cov ntaub ntawv tsim vaj tsev, tshuab, tshuab kev lag luam thiab lwm yam lag luam, cov khoom siv hluav taws xob sib txawv yog siv rau cov hom phiaj kev lag luam sib txawv.
2. Cov qauv ntawm cov cua sov:
Txawm hais tias muaj ntau ntau hom kev lag luam muaj hluav taws xob, los ntawm cov qauv yooj yim, lawv feem ntau suav nrog peb ntu:
(1) Kev siv cua sov: suav nrog cov khoom siv tshuab uas muab ntau yam khoom siv cua sov rau cov khoom siv hauv cov chaw lag luam cua sov. Xws li: lub zog nruab nrab cov raj xa dej thiab cov cuab yeej siv zog, kev xa xov hluav taws xob system transformer khoom, thiab lwm yam.;
(2) Muaj cov tshuab ua kom sov lub cev: qhov no yog cov qauv kev yooj yim ntawm cov tshuab ua kom sov, suav nrog cov qauv thav duab ua haujlwm, cov tshuab ua kom sov lub cev, cov qauv xa khoom, thiab lwm yam.;
(3) cov pa luam yeeb system: mas suav nrog cov nplaim taws, pa taws, pa taws ua kom sov thiab pa pa taws cov cuab yeej siv, thiab lwm yam.;
(4) Lwm cov khoom txhawb nqa.
