Kev tshawb fawb txog cov kav tooj liab rau cov tub yees thiab cua txias
Cov kav dej tooj liab yog qhov tseem ceeb hauv lub tub yees thiab cua txias, cuam tshuam rau kev ua haujlwm ntawm lub tshuab cua txias. Niaj hnub no, peb yuav tham txog kev ua tau zoo, pawg thiab cov teeb meem tshwm sim ntawm cov tub yees thiab cua txias cov kav dej tooj liab. Dab tsi yog cov kav dej tooj liab rau cua txias?
Cov kav hlau txais xov tooj cua tuaj yeem muab faib ua cov kav hlau txais xov tooj cua zoo tib yam thiab degreased cua txias cov kav dej tooj liab. Lub tshuab cua txias: Lub thickness feem ntau yog 0.5mm tuab rau 2-point thiab 3-point raj, 0.6mm tuab rau 4-point raj, { {10}}.7mm tuab rau 5-taw tes thiab 6-point raj; Feem ntau siv rau R22, thiab lub siab tswj ntawm 0.98MPa.
Degreased cua txias cov yeeb nkab tooj liab: kuj hu ua "degreased cua txias tooj liab yeeb nkab", lub 2-point thiab 3-point pipes yog 0.8mm tuab, thiab cov 4- taw tes, 5-point thiab 6- cov kav dej yog 1.0mm tuab. Feem ntau siv rau cov tub yees tshiab xws li R410, nrog lub siab tswj ntawm 1.8MPa.
1. Kev faib tawm tshwj xeeb ntawm cov khoom cua txias tooj liab yeeb nkab
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 yog cov yam ntxwv ntawm cov pa oxygen tsawg heev. thiab ib qho me me ntawm deoxidizer tshuav nyob rau hauv deoxidized tooj liab;
2) Oxygen tooj liab: Muaj cov tooj liab zoo tib yam (T1, T2, T3, thiab lwm yam) thiab tawv tooj liab, uas muaj cov ntsiab lus siab oxygen;
3) Cov tooj liab tshwj xeeb: Muaj arsenic tooj liab, nyiaj tooj liab, tellurium tooj liab, thiab lwm yam, uas yog tus cwj pwm los ntawm kev ntxiv cov kab sib txawv ntawm cov khoom sib txawv kom ua tiav lub hom phiaj ntawm kev txhim kho tag nrho cov khoom siv.
