Kev faib tawm ntawm cov raj tooj liab
1. Lub tshuab cua txias tooj liab tuaj yeem muab faib ua cov cua txias zoo tib yam tooj liab raj thiab degreased cua txias tooj liab raj.
Lub tshuab cua txias: Lub thickness feem ntau yog {{0}}.5mm rau 2-point thiab 3-point raj, 0.6mm rau 4-point raj , thiab 0.7mm rau 5-point thiab 6-point raj; Feem ntau siv rau R22, lub siab tswj ntawm 0.98MPa.
Degreased cua txias tooj liab raj: kuj hu ua "degreased cua txias tooj liab tubes", {{0}}point thiab 3-point tubes yog 0.8mm tuab, 4-point , 5-point, thiab 6-point raj yog 1.0mm tuab. Feem ntau yog siv rau cov tub yees tshiab xws li R410, lub siab yog tswj ntawm 1.8MPa.
2. Kev faib tawm tshwj xeeb ntawm cov khoom siv cua txias tooj liab tube:
1) Oxygen-dawb tooj liab: suav nrog high-purity oxygen-dawb tooj liab (TU0, TU1, TU2) thiab phosphorus deoxidized tooj liab (TUP, TP1, TP2, thiab lwm yam), uas muaj cov ntsiab lus tsis tshua muaj oxygen, thiab ib qho me me ntawm deoxidizer tseem nyob hauv deoxidized tooj liab;
2) Oxygen-muaj tooj liab: feem ntau zoo tib yam tooj liab ntshiab (T1, T2, T3, thiab lwm yam) thiab tawv tooj liab, uas muaj cov ntsiab lus oxygen siab;
3) Cov tooj liab tshwj xeeb: arsenic tooj liab, nyiaj tooj liab, tellurium tooj liab, thiab lwm yam., tus cwj pwm los ntawm kev sib ntxiv ntawm cov kab sib txawv ntawm cov khoom sib txawv kom ua tiav lub hom phiaj ntawm kev txhim kho kev ua tiav ntawm cov khoom.
