Cov khoom lag luam
JIS G3125 Qib spa -} C steel phajbelongs rau huab cua - ionistant steel phaj. Thiab tus qauv cuam tshuam yog JIS G3125. Spa - c steel txhua tus ua los ntawm cov hlau thiab tooj liab, npib tsib xee, thiab lwm yam tshuaj lom neeg. Cov ntsiab lus ntawm cov tshuaj lom neeg no, tsuas yog ob peb feem pua.
Vim tias cov khoom sib txawv sib txawv, huab cua kev tiv thaiv steel muaj cov khoom zoo dua, nrog rau kev ua haujlwm ntau dua corrosion. Yog li, spa - C steel siv rau cov tubrog nkoj, thawv, txuas hniav, thiab tsheb ciav hlau.

daim ntawv thov
Spa - Crea Hlau Hlauyog haum rau ntau hom welded, bolted, thiab riveted qauv, kev ua kom zoo tshaj plaws corrosion, ua rau lawv zoo tshaj rau cov ntawv thov kev tsim qauv. Cov hlau feem ntau muaj apaib lub zog ntawm 245-355 mpathiab aLub zog tensile ntawm 400-550 mpa, nrog thicknesses txij li4-25 hlithiab dav mus txog1500 hli, kom ntseeg tau kev ntseeg siab rau ntau qhov chaw ua haujlwm loj.
Lawv feem ntau siv nyob rau hauvHlau ncej qauv hlau, muab cov khoom ruaj ruaj ruaj khov - cov kabmob txhawb nqa cov tuam tsev thiab kev lag luam cov chaw. HauvChoj Engineering, Spa - C steel can tuaj yeem tiv thaiv ntev {1}-}}}}}}Tshaj 20 xyooThaum thaum txo kev saib xyuas ntau zaus.
Tsis tas li ntawd, spa {- C steel daim hlau tau dav siv hauv kev tsim khoom ntawmTso Tsheb Hlau Luam thiab Ntim, nyob qhov twg ntawm cov txheej txheem kev tiv thaiv kab xeb kom ua kom ntev} Lub neej huab cua tsis zoo, cov kev pabcuam txuas ntxiv lub neej los ntawm15-20 xyooCov. Tus qauv hlau kuj haum raukev nqus tshuab, muaj peev xwm nrog nrog siab - kub flue gas ib puag ncig (Tsawg dua los yog sib npaug rau 350 degree) yam tsis muaj kev cuam tshuam tseem ceeb. Nyob rau hauv kev thauj mus los hauv kev lag luam, spa - c yog siv rauLub Tsheb Tsim Txheej Txheem, xws li cov tsheb ciav hlau thiab thauj khoom siv cov khoom siv thauj khoom, txo lub tsheb phaus los ntawm10%–15%Thaum txhim kho kev muaj zog tag nrho thiab kav ntev.
Hauv cov ntsiab lus xaus, spa - Creasing steel daim hlau, nrog lawvZoo heev corrosion, muaj lub zog nruab nrab (tawm los 245-355 MPa), lub neej ntev, thiab ua tiav qhov yooj yim, tau siv dav thoob plaws kev tsim kho, kev thauj mus los, kev lag luam, thiab lub zog thiab hluav taws xob. Seb puas thauj {{{{}} cov kabmob qauv lossis cov khoom sib xyaw ua ke muab cov khoom siv tau thiab ntev}}} lub sij hawm ruaj khov.
