Simbi inorongwa uye inorongwa mumapoka mana: Simbi dzekabhoni, Simbi dzesimbi, Simbi dzisina ngura Simbi dzemidziyo
Rudzi 1-Simbi dzekabhoni
Kunze kwekabhoni nesimbi, simbi dzekabhoni dzine huwandu hushoma hwezvimwe zvikamu. Simbi dzekabhoni ndidzo dzinonyanya kuwanikwa pamhando ina dzesimbi, zvichiita 90% yekugadzirwa kwesimbi yese! Simbi yekabhoni inokamurwa mumapoka matatu zvichienderana nehuwandu hwekabhoni musimbi:
l Simbi dzisina kabhoni yakawanda/simbi dzisina kabhoni yakawanda (kusvika ku0.3% kabhoni)
l Simbi dzekabhoni dziri pakati nepakati (0.3–0.6% kabhoni)
l Simbi dzine kabhoni yakawanda (inopfuura 0.6% kabhoni)
Makambani anowanzogadzira simbi idzi dzakawanda sezvo dzisingadhuri uye dzakasimba zvakakwana kuti dzishandiswe mukuvaka kukuru.
Rudzi rwechipiri-Simbi dzesimbi
Simbi dzesimbi dzinogadzirwa nekubatanidza simbi nezvimwe zvinhu zvakaita senickel, mhangura, chromium uye/kana aluminium. Kubatanidza zvinhu izvi kunovandudza simba, ductility, resistance corrosion uye machinability yesimbi.
Rudzi rwechitatu-Simbi dzisina ngura
Magiredhi esimbi isina ngura anosanganiswa ne10–20% chromium pamwe chete nenickel, silicon, manganese, uye kabhoni. Nekuda kwekuwedzera kugona kwavo kurarama nemamiriro ekunze asina kunaka, simbi idzi dzinodzivirira ngura zvakanyanya uye dzakachengeteka kushandiswa pakuvaka panze. Magiredhi esimbi isina ngura anowanzo shandiswawo mumidziyo yemagetsi.
Semuenzaniso, simbi isingasvibi 304 inotsvakwa zvakanyanya nekuda kwekugona kwayo kutsungirira nharaunda uku ichichengetedza zvinhu zvemagetsi zvakachengeteka.
Kunyange zvazvo mhando dzakasiyana dzesimbi dzisina ngura, kusanganisira 304 simbi dzisina ngura, dzichishandiswa muzvivakwa, simbi dzisina ngura dzinowanzo tsvakwa nekuda kwehutsanana hwadzo. Idzi simbi dzinowanikwa zvakanyanya mumidziyo yekurapa, mapaipi, midziyo yekumanikidza, zvishandiso zvekucheka uye michina yekugadzira chikafu.
Rudzi rwechina-Zvishandiso zvesimbi
Sezvinoratidzwa nezita racho, simbi dzezvishandiso dzinoshanda zvakanaka pakucheka nekuboorera. Kuvapo kwetungsten, molybdenum, cobalt uye vanadium kunobatsira kuvandudza kusapisa uye kugara kwenguva refu. Uye nekuti dzinoramba dzakaita chimiro chadzo kunyangwe dzichishandiswa zvakanyanya, ndidzo dzinonyanya kufarirwa pakushandisa zvishandiso zvemaoko.
Kurongwa kwesimbi
Kunze kwemapoka mana, simbi inogonawo kuiswa muzvikamu zvichienderana nezvinhu zvakasiyana zvinosanganisira:
Kuumbwa: carbon range, alloy, stainless, nezvimwewo.
Nzira yekupedzisa: yakaputirwa inopisa, yakaputirwa inotonhora, yakaputirwa inotonhora, nezvimwewo.
Nzira yekugadzira: choto chemagetsi, chigadziko chinoenderera mberi, nezvimwewo.
Magadzirirwo emukati memuviri: ferritic, pearlitic, martensitic, nezvimwewo.
Simba remuviri: zvichienderana neASTM standards
Maitiro ekubvisa oxidation: kuurayiwa kana kuurayiwa zvishoma
Kurapa kupisa: kunyoroveswa, kunyoroveswa, nezvimwewo.
Mazita emhando yepamusoro: mhando yekutengeserana, mhando yemidziyo inomanikidzwa, mhando yekudhirowa, nezvimwewo.
Ndeipi mhando yakanakisisa yesimbi?
Hapana mhando yesimbi "yakanakisisa" inowanikwa pasi rose, sezvo mhando yesimbi yakakodzera kushandiswa inoenderana nezvinhu zvakawanda, zvakaita sekushandiswa kwainotarisirwa, zvinodiwa nekanika uye zvemuviri, uye miganhu yemari.
Magiredhi esimbi anoshandiswa nguva dzose uye anoonekwa seanonyanya kutevedzana kubva mumhando imwe neimwe anosanganisira:
Simbi dzekabhoni: A36, A529, A572, 1020, 1045, uye 4130
Simbi dzesimbi: 4140, 4150, 4340, 9310, uye 52100
Simbi dzisina ngura: 304, 316, 410, uye 420
Zvishandiso zvesimbi: D2, H13, uye M2
JINDALAI ndiyo boka resimbi rinotungamira rinogona kupa mhando dzese dzesimbi dzakadai se coil, sheet, pipe, chubhu, rod, bar, flanges, gokora, tees, nezvimwewo. Ipa Jindalai chivimbo, uye uchagutsikana nechigadzirwa chacho.
