Peb muab tag nrho ntau yam ntawm lub qhov rooj xauv qhov rooj, muaj nyob nrog cov bolt-down los yog xauv-kev ruaj ntseg qauv.
Peb lub Hoobkas muab cov txheej txheem siab, kev tsim khoom zoo raws li cov neeg siv khoom kos duab, cov npe tshwj xeeb thiab cov qauv tsim. Peb txhawb nqa qhov project hauv cheeb tsam thiab xa cov kev daws teeb meem zoo rau cov neeg yuav khoom thoob ntiaj teb.
Ductile hlau manhole npog poob rau hauv cov khoom siv hlau cam khwb cia. Thaum lub sij hawm tsim, molten hlau tau txais spheroidizing thiab inoculation kev kho mob los tsim spheroidal graphite nyob rau hauv lub casting. Cov txheej txheem no txhawb nqa cov khoom ua tau zoo, tshwj xeeb tshaj yog plasticity thiab toughness. Nyob rau hauv qee qhov kev pabcuam, nws lub zog tuaj yeem tshaj carbon steel.
Nrog rau cov yam ntxwv zoo ntawm cov khoom siv no, cov hlau nplaum yog qhov zoo rau cov khoom uas muaj kev ntxhov siab, qhov twg muaj zog, zoo toughness thiab hnav tsis kam.

Khoom nta thiab kev ua tau zoo
Zoo toughness
Nws cov nqi cuam tshuam zoo ib yam li cov pa roj carbon nruab nrab thiab ntau dua 10 npaug ntawm cov hlau grey.
Zoo heev Corrosion-Resistant Performance
Thaum lub sij hawm ntsev-txhaj tshuaj tiv thaiv corrosion, cov khoom poob ntau tshaj 90-hnub raug sau npe tsuas yog 1/40 ntawm cov yeeb nkab steel thiab 1/10 ntawm cov yeeb nkab hlau. Nws lub neej kev pab cuam doubles ntawm grey hlau yeeb nkab thiab ncav cuag tsib npaug ntawm lifespan ntawm tus qauv steel yeeb nkab.
Nws muaj zoo plasticity
Nws elongation yog ntau dua los yog sib npaug li 7%, zoo ib yam li siab - carbon steel, thaum grey hlau muaj ib tug elongation ntawm xoom.
Siab zog
Tensile zog ób Ntau dua los yog sib npaug rau 420MPa, yield zog ós Ntau dua los yog sib npaug rau 300MPa, tib yam li cov hlau tsis tshua muaj, thiab peb npaug ntawm cov hlau grey.
Lub ntsiab daim ntawv thov thaj chaw ntawm ductile hlau manhole npog
Txoj kev hauv nroog, txoj kev loj, kev sib txuas lus, hluav taws xob, dej, khoom siv hauv tsev, cov tsev kawm ntawv thiab lwm qhov chaw ua si.
