Ndeupi musiyano uripo pakati peSS 304 neCRCA?

Munzvimbo yemetallurgy uye engineering engineering, S.S. 304 uye CRCA (Cold Rolled Close Annealed) simbi inogara munzvimbo dzakasiyana, imwe neimwe iine yakasarudzika zvivakwa uye mashandisirwo. Muchinyorwa chino, isu tinovavarira kupa yakazara uye ine chiremera kuenzanisa pakati peSS 304 neCRCA simbi, tichitarisa kuumbwa kwavo, zvivakwa, uye mashandisiro.

Ndeupi musiyano uripo pakati peSS 304 neCRCA?

Chekutanga, ngatitarisei kuumbwa kweSS 304. SS 304, inozivikanwawo seSUS304 kuJapan kana AISI 304 pasi rose, austenitic simbi isina tsvina giredhi. Kuumbwa kwayo kwemakemikari kunonyanya kuve nesimbi, chromium, uye nickel. Iyo chromium yemukati inowanzobva pa18% kusvika 20%, nepo nickel yemukati inenge 8% kusvika 10.5%. Uku kusanganiswa kwezvinhu kunopa SS 304 yayo yakanakisa kushora kuramba, ichiita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa uko kuratidzwa kune corrosion nharaunda kungangoita. Uye zvakare, SS 304 ine zvakare inoteedzera huwandu hwekabhoni, manganese, silicon, phosphorus, sarufa, uye nitrogen, iyo inowedzera kuwedzera kwayo michina uye yemuviri.

Kune rimwe divi, CRCA simbi imhando yekabhoni simbi yakagadziriswa kuburikidza nekutonhora kukunguruka uye kuvhara annealing. Cold rolling inosanganisira kukungurutsa simbi pane tembiricha yekamuri kana pazasi, izvo zvinovandudza kupera kwayo kwepamusoro uye michina. Close annealing inzira yekurapa kupisa iyo inobvisa kushushikana kwemukati uye inonatsiridza ductility uye kusimba kwesimbi. Kemikari yeCRCA simbi inonyanya kuve nesimbi uye kabhoni, ine huwandu hwakasiyana hwezvimwe zvinhu zvakaita semanganese, phosphorus, uye sarufa zvichienderana negiredhi chairo.

Zvino, ngatienderere mberi kune zvivakwa zvezvinhu zviviri izvi. SS 304 inozivikanwa nekunaka kwayo kwekusagadzikana, izvo zvinokonzerwa nekuumbwa kweiyo yakatetepa, inodzivirira oxide layer pamusoro payo. Iyi nhanho inodzivirira kuwedzera kukorona nekuvharira kusangana pakati pesimbi uye corrosive agents. SS 304 inoratidzawo yakanaka ductility, weldability, uye kuumbwa, zvichiita kuti zvive nyore kushanda nayo uye yakakodzera kune akasiyana maitiro ekugadzira. Pamusoro pezvo, ine yakanaka yekupisa kupisa uye inogona kushandiswa mune yakakwirira-tembiricha maapplication.

Pane zvinopesana, CRCA simbi inozivikanwa nekusimba kwayo kwepamusoro uye kuoma. Cold rolling inowedzera simba regoho resimbi uye kusimba kwesimba, zvichiita kuti ive yakakodzera kune zvikumbiro zvinoda kusimba kwepamusoro. Iyo yekuvhara nzira yekuvhara inowedzera kunatsiridza ductility uye kusimba kwesimbi, ichiibvumira kutsungirira deformation uye kukanganisa pasina kutsemuka. Nekudaro, CRCA simbi haina kuita ngura seSS 304 uye ingangoda mamwe marapirwo kana marapirwo kuti idzivirire kubva mukuora mune dzimwe nzvimbo.

Kana zvasvika kumashandisirwo, SS 304 uye CRCA simbi vane niches yavo. SS 304 inoshandiswa zvakanyanya muindasitiri yekugadzira chikafu, midziyo yekurapa, uye zvikumbiro zvekuvaka nekuda kwekuramba kwayo kuita ngura uye nyore kuchenesa. Inowanikwawo mumakemikari ekugadzira zvidyarwa, nharaunda dzemugungwa, uye dzimwe nzvimbo uko kuora kunetsa. Kune rimwe divi, CRCA simbi inowanzo shandiswa muindasitiri yemotokari, kuvaka, uye kugadzira michina nekuda kwesimba rayo uye kuoma kwayo. Iyo inonyanya kukodzera kune zvikumbiro zvinoda kunyatso uye kushivirira kwakasimba, senge mota dzemuviri mapaneru uye nemazvo emuchina zvikamu.

mhedziso

Mukupedzisa, SS 304 uye CRCA simbi zvinhu zviviri zvakasiyana zvine akasiyana zvivakwa uye mashandisirwo. SS 304 inokunda mukupokana uye inoshandiswa zvakanyanya munzvimbo dzinonetsa. Iyo yakanaka ductility, weldability, uye kuumbwa kunoita kuti ive chinhu chakasiyana-siyana chakakodzera kuwanda kwemaitiro ekugadzira. Kune rimwe divi, CRCA simbi inozivikanwa nekusimba kwayo kwepamusoro uye kuomarara, ichiita kuti ive yakakodzera kune zvimiro zvekushandisa zvinoda kunyatso uye kusimba.

Ndatenda nekuverenga chinyorwa chedu uye tinovimba chinogona kukubatsira kuti uve nekunzwisisa kurinani kwemutsauko uripo pakati peSS 304 neCRCA. Kana iwe uchitsvaga SS 304 vatengesi uye vagadziri pamhepo izvozvi, tinokupa zano kuti ushanyire Sino Stainless Steel.

Semutengesi anotungamira wezvigadzirwa zvesimbi isina tsvina kubva kuShanghai China, Sino Stainless Steel inopa vatengi vemhando yepamusoro. Stainless simbi coils, simbi isina tsvina, simbi isina tsvina yekushongedza mapepa, machubhu esimbi asina tsvina, pombi dzesimbi dzisina tsvina, mahwendefa esimbi asina tsvina, uye simbi isina tsvina pamutengo wakakwikwidza zvikuru.
