Lub categorized rau hauv cov qauv no yuav tsum yog qhib-hearth, basic-oxygen lossis hluav taws xob ua kom tiav thiab yuav tsum muaj cov tshuaj raws li nram qab no : carbon, manganese, phosphorus, sulfur, tooj liab, npib tsib xees, chromium, molybdenum, thiab vanadium. Txoj hlua yuav tsum tau siv txoj hlua khi los yog siv txoj hlua. Kev sib sab laj, khoov, thiab kev sib tw yuav tsum tau ua kom paub tseeb tias nws yuav tsum ua raws li cov khoom sib luag ntawm tus qauv. Txoj kev ntsuas hydrostatic yuav tsum tau siv, tsis muaj qhov tov los ntawm cov plhaub weld lossis cov kav dej. Nondestructive electric test yuav tsum tau ua kom paub tseeb tias qhov puv ntim ntawm cov yeeb nkab yuav tsum ua raws li tus qauv. Tus neeg yuav khoom muaj txoj cai los mus ua ib qho ntawm cov kev kuaj xyuas thiab kev ntsuam xyuas uas tau teev nyob rau hauv qhov kev qhia no uas pom tau tias yuav tsum tau kho kom cov yeeb nkab haum rau cov kev cai tswjfwm.

Khoom Advangtages
Nrog rau txoj kev lag luam, kev muag khoom kub-muag khoom lag luam tau siv rau ntau lub teb. Qhov zoo ntawm kev kub-dip galvanizing yog tias lub sij hawm los tiv thaiv lub sij hawm ntev ntev, thiab kev ua kom haum rau qhov chaw yeej ib txwm muaj kev tiv thaiv nrov kev kho tus qauv. Nws yog dav siv rau hauv lub hwj chim yees, kev sib txuas lus yees, kev sib txuas ntawm txoj kev loj, txoj kev tiv thaiv kev loj, kev sib tshuam ntawm txoj kev lag luam, kev tsim vaj tse, kev tsim khoom, kev lag luam, thiab lwm yam. , tab sis xyoo ntawm kev tiv thaiv corrosion yog txawv nyob rau hauv cov cheeb tsam sib txawv: 13 xyoos nyob rau hauv kev lag luam hnyav, 50 xyoo nyob hauv dej hiav txwv, 104 xyoo nyob rau hauv lub suburbs, thiab 30 xyoo nyob rau hauv lub nroog.
Lub hauv paus ntsiab lus ntawm kub-dip galvanizing: hlau qhov chaw ntxuav, ces kho nrog hnyav, qhuav thiab ces immersed nyob rau hauv cov kua zinc. Cov hluav taws reacts nrog lub zim zinc rau ib qho ziab txheej alloyed. Tus txheej txheem yog: degreasing - ntxuav - ntxuav - Co-plating - ziab - kub dip galvanizing - sib cais - txias txog passivation.
Lub thickness ntawm kub-dip galvanized alloy txheej feem ntau nyob ntawm cov tshuaj lom neeg muaj pes tsawg leeg xws li silicon cov ntsiab lus ntawm cov hlau, thaj tsam ntawm cheeb tsam ntawm cov hlau, lub roughness ntawm cov hlau deg, zinc qws kub, zinc immersion lub sijhawm , qhov txias ceev, thiab qhov txias dua deformation.
Zoo ntawm kub dip galvanizing
1. Cov nplaum hlau ntawm cov yeeb nkab yog ntev check nrog txoj kev los tiv thaiv cov paj ntaub, tsis dhau oxidation, thiab tsis pub ua xeb dawb ntawm cov yeeb nkab;
2. Cov yeeb nkab hlau yog tiv thaiv tag nrho. Tom qab cua sov, txhua feem ntawm cov yeeb nkab yog plated nrog zinc, thiab qhov chaw concave thiab convex yog tiv thaiv;
3. Nws muaj cov yam ntxwv ntawm kev tiv thaiv corrosion thiab hnav kev ua haujlwm, yog li ntawd cov yeeb nkab steel yuav siv tau ntev zog;
4. Txij li thaum zinc tau plated rau sab nrauv ntawm cov yeeb nkab, lub sij hawm rau roj los yog lacquering nraum zoov yog rho tawm, thiab kev tsim kho yog yooj yim dua;
5. Cov yeeb nkab tsis sib xyaw xim yuav tsis khov thiab txhuam hauv peb los yog cuaj hnub, thiab yog qhov tshwj xeeb tshaj yog rau qhov chaw txias ntawm sab qaum teb.
