Cov cib hlau ntwsxa mus rau cov cib refractory hollow uas tau muab tso rau hauv cov qhov ntawm lub phaj hauv qab ntawm ingot casting los txuas cov cib hlau ntws thiab cov pwm ingot, feem ntau hu ua cib khiav. Feem ntau yog siv los txo qhov tsis kam ntawm cov hlau molten ntws thiab tiv thaiv cov hlau xau. Cov yam ntxwv tseem ceeb suav nrog kev tiv taus kub siab, kev hnav tsis kam, kev ua haujlwm zoo, kev teeb tsa yooj yim thiab kev tiv thaiv hluav taws zoo.
1. Kev faib tawm los ntawm cov khoom siv:
(1) Av nplaum:Qhov no yog hom cib hlau yooj yim tshaj plaws, ua los ntawm cov av nplaum ib txwm. Txawm hais tias tus nqi qis, nws tsis tshua muaj zog tiv taus hluav taws thiab lub neej ua haujlwm, thiab nws tsim nyog rau qee lub Hoobkas hlau me me lossis cov xwm txheej siv ib ntus.
(2) Aluminium siab:Cov cib hlau no muaj cov txhuas ntau, tiv taus hluav taws zoo heev, thiab tuaj yeem ruaj khov hauv qhov kub thiab txias. Nws feem ntau siv rau hauv cov lag luam hlau loj, tshwj xeeb tshaj yog hauv cov txheej txheem ua hlau uas yuav tsum tau tiv taus qhov kub thiab txias ntev.
(3) Mullite:Cov siv lead ua zoo li koob saum npoo av ua rau muaj cov qauv sib txuas, uas tuaj yeem tiv thaiv kev yaig los ntawm cov hlau yaj. Tam sim no nws yog cov khoom siv tseem ceeb.
2. Kev faib tawm los ntawm kev ua haujlwm:
(1) Nruab Nrab Cib
Siv rau hauv thaj chaw tseem ceeb ntawm cov hlau molten, txhawb nqa txoj kev ntws thiab xav tau siab
refractoriness thiab erosion tsis kam.
(2) Cov Cib Hlau Divider
Siv los hloov cov hlau uas yaj mus rau ntau hom pwm. Cov lus qhia tshwj xeeb suav nrog ob lub qhov, peb lub qhov, thiab plaub lub qhov, nyob ntawm seb cov txheej txheem xav tau dab tsi.
(3) Cov Cib Tail
Nyob rau ntawm qhov kawg ntawm lub tshuab hlau ntws, lawv tiv taus qhov cuam tshuam ntawm cov hlau molten thiab qhov kub siab thiab xav tau kev tiv thaiv kom tawg.
