| Njira Yopangira Chitoliro Chosapanga Chitsulo |
Kupanga chitoliro chachitsulo chosapanga dzimbiri kumaphatikizapo njira zotsatirazi: kusankha zinthu zopangira, mafuta odzola, kupukuta, kupukuta, kuyeretsa asidi, kujambula kozizira, kuyesa kwa ultrasound, ndi kulongedza komaliza. Gawo lililonse limaonetsetsa kuti chitolirocho chikukwaniritsa miyezo yapamwamba yaubwino, kulondola, komanso kumalizidwa pamwamba.
| Mayeso a Chitoliro Chosapanga Chitsulo Chosapanga Chitsulo |
Kuyesa kukhwima kwa mapaipi achitsulo chosapanga dzimbiri ndi njira yofunika kwambiri yowunikira yomwe imagwiritsidwa ntchito poyesa mtundu wa pamwamba pa chitoliro chamkati kapena chakunja. Kukhwima kwa pamwamba, komwe nthawi zambiri kumayesedwa mu Ra (avereji ya kukhwima), kumakhudza magwiridwe antchito a madzi, kukana dzimbiri, komanso ukhondo—makamaka m'mafakitale monga mankhwala, kukonza chakudya, ndi kupanga ma semiconductor. Pogwiritsa ntchito zida zolondola monga ma profilometers a pamwamba, oyang'anira amatsimikiza kuti chitolirocho chikukwaniritsa zofunikira, monga Ra ≤ 0.8 µm kapena Ra ≤ 0.2 µm, kutengera momwe ntchitoyo ikugwiritsidwira ntchito. Kuonetsetsa kuti kukhwima kwa pamwamba kumathandizira kuti ntchito ya chinthucho igwire bwino ntchito, ukhondo, komanso kulimba.

| Kuyesa kwa Eddy Current kwa Machubu Osapanga Chitsulo |
Kuyesa kwa Eddy current ndi njira yosawononga (NDT) yomwe imagwiritsidwa ntchito kuzindikira zolakwika pamwamba ndi pafupi ndi pamwamba m'machubu achitsulo chosapanga dzimbiri. Njirayi ndi yothandiza kwambiri pozindikira ming'alu, mabowo, ndi zina zomwe sizingachitike popanda kuwononga zinthuzo. Mwa kulowetsa mphamvu yamagetsi mu chubu ndikuyang'anira kusintha kwa kayendedwe ka eddy current, oyang'anira amatha kuwona mwachangu kukhulupirika kwa khoma la chubu. Kuyesa kwa Eddy current kumagwiritsidwa ntchito kwambiri popanga machubu achitsulo chosapanga dzimbiri osasokonekera komanso olumikizidwa, makamaka pakugwiritsa ntchito chosinthira kutentha, boiler, ndi zida. Kumatsimikizira kudalirika kwa zinthu ndikutsatira miyezo yamakampani monga ASTM E426 ndi EN 10246-3.
| Kuyesa kwa Ferrite Content |
Kuyesa kuchuluka kwa ferrite ndi njira yofunika kwambiri yowongolera khalidwe la mapaipi achitsulo chosapanga dzimbiri, makamaka omwe amapangidwa kuchokera ku magiredi a austenitic kapena duplex. Kuyesa kosawononga kumeneku kumayesa kuchuluka kwa gawo la ferrite lomwe lili muzinthu zapaipi kapena malo owetera kuti zitsimikizire kukana dzimbiri bwino, magwiridwe antchito amakina, komanso kulimba kwa weld. Kuchuluka kwa ferrite kochulukirapo kapena kosakwanira kungayambitse mavuto monga kusweka kwa dzimbiri kapena kuchepa kwa kulimba. Kuyesa kumachitika nthawi zambiri pogwiritsa ntchito njira zamagetsi zoyambitsa (monga Ferrite Scope), ndipo kumatsatira miyezo monga ASTM E562, ISO 8249, kapena AWS A4.2. M'machitidwe a mapaipi omwe amagwiritsidwa ntchito m'malo ofunikira - monga nsanja zakunja kwa nyanja, zombo zopanikizika, ndi zomera zamankhwala - kuwongolera kuchuluka kwa ferrite ndikofunikira kwambiri kuti pakhale kudalirika komanso chitetezo kwa nthawi yayitali.

| Yankho la Pa intaneti Kumangirira Machubu a Chitsulo Chosapanga Dzimbiri |
Kuthira mankhwala ophera tizilombo pa intaneti ndi njira yochiritsira kutentha yomwe imagwiritsidwa ntchito pa machubu achitsulo chosapanga dzimbiri panthawi yopanga kuti awonjezere kukana dzimbiri, mphamvu ya makina, komanso kufanana kwa kapangidwe kake. Munjira iyi, machubu amatenthedwa mofulumira mpaka kutentha kothira mankhwala—nthawi zambiri pakati pa 1000°C ndi 1150°C—kutsatiridwa ndi kuziziritsa kolamulidwa, nthawi zambiri pogwiritsa ntchito madzi kapena mpweya wopanda mpweya. Mankhwalawa amasungunula ma carbide precipitates ndikubwezeretsa kapangidwe ka austenitic, komwe ndikofunikira kwambiri pamagiredi monga 304 ndi 316. Mwa kuphatikiza gawo ili mwachindunji pamzere wopanga, kuthira mankhwala ophera tizilombo pa intaneti kumatsimikizira mtundu wokhazikika, kumawonjezera magwiridwe antchito, ndikuchotsa kufunikira kwa kuthira mankhwala osiyana.

| Kuyesa kwa PT kwa Machubu Osapanga Chitsulo |
SAKY STEEL imayesa PT yolowera m'mapaipi achitsulo chosapanga dzimbiri ndi zinthu zina monga gawo la njira yathu yowongolera khalidwe. PT ndi njira yoyesera yosawononga yomwe imagwiritsidwa ntchito kuzindikira zolakwika pamwamba monga ming'alu ndi zinthu zomwe sizikuwoneka ndi maso.
Oyang'anira athu ophunzitsidwa bwino amagwiritsa ntchito zipangizo zapamwamba kwambiri zolowera komanso zopangira zinthu kuti atsimikizire zotsatira zolondola komanso zodalirika. Njira zonse za PT zimatsatira miyezo yapadziko lonse lapansi komanso zofunikira za makasitomala zomwe zimatsimikizira chitetezo cha malonda ndi magwiridwe antchito.
