Isitimela Sensimbi se-EN R260 R350HT | Isitimela Sesitimela Esinamandla Aphezulu | Ikhwalithi Yokuthumela Ngaphandle
I-EN R260 / R350HTIzinsimbi Zensimbiyizitimela eziqinile ezifanelekela imizila yesitimela, imizila yezimboni kanye nezinhlelo zokusebenza zokuthutha ezisindayo. Ngaphansi kwe-EN 13674, izitimela zenziwe ngendlela ephelele ukuze zisebenze kahle kakhulu, ziphile isikhathi eside futhi ziphephe ngokwethembeka ngisho noma zithwele kanzima.

Amandla aphezulu nokuqina Impilo ende
Isitifiketi se-ISO kanye nokuhambisana nezindinganiso ze-EN 13674
Ilungele ukusetshenziswa okungahleliwe kanye nokusetshenziswa kwezimboni
Ukwakheka kwamakhemikhali okukhethekile kokuqina okuphezulu nokumelana nokuguguleka
Itholakala ngobude obuhlukene, izisindo kanye namaphrofayili ukuze ivumele ukusetshenziswa okuguquguqukayo!
1. Ukulungiswa Kwezinto Ezingavuthiwe
Khetha ama-billet noma izimbali zensimbi zekhwalithi enhle.
Hlola ukwakheka kwamakhemikhali kanye namaphutha
2. Ukushisa Nokugingqa
Shisa ama-billets esithandweni somlilo kuze kufike ekushiseni okugoqekayo.
UKUGQIBELA OKUSHISAYO: I-billet yensimbi igoqwa ngokushisa ibe yi-rail yekhwalithi ephezulu (25 kg/m kuya ku-60 kg/m) nge-rolling mill.
3. Ukupholisa Nokuqondisa
Ukupholisa okulawulwayo ukuze kube nokuqina nokuqina okulungile.
Imizila ye-Polish ibe nobukhulu obufanele, iqondisa imizila njengoba kudingeka.
4. Ukusika Nokuqedela
Sika izinsimbi zokusika zibe usayizi (12-25 m kuyinto evamile).
Qedela ubuso bekhanda, unyawo kanye nobuso bewebhu
5. Ukuhlolwa Kwekhwalithi
Hlola izakhiwo zensimbi (ukuguquguquka, ukuthambekela, ubulukhuni).
Kala osayizi kanye nekhwalithi yobuso.
Yenza i-NDT uma kudingeka.
6. Ukulungiselela Ukupakisha Nokuthumela
Bopha izinsimbi zokubopha ngezinqwaba, engeza izivalo zokugcina ezivikelayo.
Mboza ngesembozo esingangenwa manzi ukuze uthunyelwe kwamanye amazwe kuphela.
"Layisha ukulethwa noma ukuthunyelwa"
Ukwakhiwa kwemizila yesitimela yezitimela zezimpahla nabagibeli
Izitimela zezimboni zezimayini, amachweba, kanye nezindawo zokugcina impahla
Imizila ethwala umthwalo omningi yokuphatha izinto zokwakha ezindaweni zokuthutha kanye nezimboni
Ukuvuselelwa nokugcinwa kwezitimela ezikhona
Izinsimbi zokuthutha ezisemabhokisini okhuni noma ensimbi ukuze kuthuthwe ngokuphephile
Ukuthuthwa kwebanga elide kanye nemithwalo yolwandle egoqwe ngendlela engangeni manzi
Izivalo zepulasitiki noma zensimbi ekugcineni ukuvimbela umonakalo lapho ulayisha/wehlisa
Ukuthunyelwa kwesayithi lomthengi kusuka endaweni yakhe kuya endaweni yakhe kuyatholakala ngokulandelela
I-MTC ephelele yazo zonke izimpahla ezilethwayo
1. Ziyini izitimela ze-EN R260 kanye ne-R350HT?
Ziyizinga lekhwalithi yensimbi ezihlukaniswe ngokwezindinganiso zesitimela zesitimela zaseYurophu. I-R260 inconywa emizileni ejwayelekile yabagibeli neyempahla, kanti i-R350HT iyisitimela esinamandla kakhulu esifanele ukusetshenziswa kwemithwalo enzima. Zombili zihambisana nezinga le-EN 13674.
2. Yiziphi izindawo eziyinhloko zokusetshenziswa?
Isitimela(abagibeli nempahla), izitimela zezimboni ezimayini, emachwebeni, nasemafektri; izitimela zezokuthutha ezisindayo zezindawo zokuthutha kanye namapaki ezimboni; ukulungiswa kanye nokufakwa esikhundleni kwezitimela ezifakiwe.
3. Unga-oda kanjani futhi uthumele ngaphandle?
Ukuthunyelwa kwamanye amazwe ngesitimela kudinga isitifiketi se-MTC, futhi ukupakisha kumele kuhambisane nezindinganiso zomhlaba wonke (ukufaka izinto, ukupakisha okungangeni manzi, izivalo zokugcina). Isikhathi sokulethwa kwesampula se-oda siyizinsuku ezingu-7-14, kanti isikhathi sokulethwa kwe-oda elikhulu singamaviki angu-3-6. Sicela uxhumane nethimba lethu lokuthengisa ukuze uthole ikhotheshini.
