STKM11A STKM14B ityhubhu yentsimbi yemoto
Inkcazo
I-STKM11A ibakala lentsimbi kwimibhobho yentsimbi yekhabhoni esetyenziswa kwizakhiwo zoomatshini, ethathwe kwi-JIS G3445 eqhelekileyo, kwaye libakala laseJapan.I-STKM11A ibakala lombhobho wensimbi, izinto ezilingana ne-SPHC, σ B ≥ 290MPa;Intsimbi yeCarbon ye-STKM yezakhiwo zemishini;
Uphawu lweSPHC ekuqaleni yayiluphawu lwaseJamani kwaye lwalusetyenziswa naseJapan.Kamva, yaziswa yintsimbi yensimbi yasekhaya i-Baosteel, emele iipleyiti zetsimbi ezishushu (ezihambelana ne-SPCC), ezilingana neeplate ezishushu ezishushu ze-10 # kunye ne-15 # yentsimbi kumgangatho wesizwe we-GB699 (uMgangatho weSizwe woMgangatho oPhezulu. I-Carbon Structural Steel), enoluhlu lwekhabhoni yomxholo ojikeleze i-0.1% -0.15%
Unyango loMphezulu:
1.Bared
2.Ipeyintiwe emnyama (ingubo yevarnish)
3.Iigalvanized
4.I-oyile
5.Ngokutsho abathengi.
I-JIS STKM11A ~ 18C/DIN ST52/ASTM A106, ukuchaneka kunye noburhabaxa bomphezulu bemibhobho yentsimbi echanekileyo etsalwa ngokubanda enedayamitha yangaphakathi nangaphandle iphezulu kunemibhobho eqengqelekayo eshushu.Iinkcukacha zinokwenziwa ngokwezifiso ukuze zihlangabezane neemfuno eziphezulu zamandla okuqina, amandla esivuno, ulwandiso, njl.Imibhobho yentsimbi echanekileyo epholileyo enobude obungaphakathi nangaphandle ingasetyenziselwa iisilinda zomoya;Isilinda soxinzelelo lweoyile;Isithuthuthu kunye nebhayisikile ukothuka;Icondenser yomoya womoya;Ifolokhwe yangaphambili yeLocomotive kunye nefolokhwe yangasemva;Ingalo yomatshini;Igranula yokuhlaziya ifilimu;Umbhobho wokukhupha;Umatshini wokuvuthela ibhotile;Umatshini wokulinganisa;uJack;Umlimi;Irola koomatshini bokushicilela, njl.
I-JIS G3445 Iityhubhu zentsimbi ezichanekileyo zisetyenziswa ikakhulu kwiimoto kunye noomatshini abachanekileyo kwiimoto kunye nesilinda.ukusetyenziswa koxinzelelo, kunye nokuthutha umphunga, amanzi, imibhobho yegesi.
