Cov ntsiab lus ntawm Silicon Carbide (Sic) hauvSilicon Carbide Refractory CasabCov kev sib txawv heev nyob ntawm daim ntawv thov cov xwm txheej thiab kev ua tau zoo. Silicon carractory castused los ntawm haixin tuam txhab feem ntau muab faib ua peb pawg: cov ntsiab lus nruab nrab, muaj kev coj dawb huv.
1. Pa Yam Hom: Cov lus siliab carlicon cov ntsiab lus yog li 30% ~ 60%. Cov khoom muaj tus nqi qis thiab yuav siv mus rau hauv tus account ob qho tib si hnav tsis kam thiab hluav taws kub tiv thaiv. Nws yog haum rau Boiler hnav cov roj resistant, cov cuab yeej loj, cov cuab yeej hlau thiab lwm qhov chaw.
2. Nruab nruab nrab-siab cov ntsiab lus Hom: Cov ntsiab lus carmide carlicon yog li 60% ~ 80%. Cov khoom muaj cov khoom zoo heev, thermal poob siab kuj, thiab nruab nrab oxidation tsis kam. Nws yog tsim nyog rau lub moj tej hluav taws xob cuam tshuam pob zeb zaum
3. Hom Siab Purity: Cov ntsiab lus Silicon Carlicid cov ntsiab lus yog li 80% ~ 95%. Cov khoom lag luam muaj huab kub kub ua kom zoo thiab corrosion tsis kam. Nws yuav tsum tau sib phim nrog antioxidants. Nws yog qhov tsim nyog rau cov khib nyiab pov tseg (tiv taus alkali hlau corrosion), cov roj cua sov, cov sintering rollers, thiab lwm yam.
Cov ntsiab lus tseem ceeb cuam tshuam rau cov ntsiab lus SIC hauv Silicon Carbide Refractory Casab:
Siv qhov kub: Thaum> 1600 degree, cov ntsiab lus SIC xav tau nce ntxiv (loj dua lossis sib npaug ntawm 70%) kom muaj kev ruaj khov.
Corrosive ib puag ncig: 60% ~ 80% SIC yog qhov yuav tsum tau nyob rau hauv kev sib cuag ntawm Molten hlau los yog slag (xws li cov hlau channel).
Thermal conductivity yuav tsum muaj: siab thermal condarivity scenarios (xws li cov cua sov hloov pauv) yuav tsum tau siab sic cov ntsiab lus (ntau dua los yog sib npaug rau 80%).
Tus nqi tswj: Tsawg sic cov ntsiab lus (30% ~ 50) tuaj yeem txo cov nqi los ntawm kev ntxiv corundum, alumina, thiab lwm yam.
Sau ntawv:
Anti-oxidation tsim:
Thaum cov ntsiab lus sic ntau dua 70%, xws li Si Hmoov, Al₂o₃) yuav tsum tau ntxiv, txwv tsis pub cov qauv ntsuas kub ua rau cov qauv xoob.
Kev Siv Ua Haujlwm:
Casting cov ntaub ntawv nrog cov ntsiab lus siab sic muaj cov lus tsis zoo thiab xav tau kom zoo dua qhov kev hloov kho lossis siv cov neeg khib.
Ci System:
Qhov siab dua cov ntsiab lus sic, cov stricter cov cua cua sov yuav tsum tau tswj hwm thaum lub sij hawm ci (tshwj xeeb yog qis dua 600 degree).
