Kana zvasvika kune simbi isina ngura, Jindalai Steel Group ndiyo chiyero chemhando yepamusoro uye hunyanzvi. Jindalai inyanzvi mukugadzira mhando dzakasiyana dzesimbi dzisina ngura, kusanganisira 201 stainless steel strip yakakurumbira uye 304 stainless steel strip yakasimba uye inogara kwenguva refu, uye yava mutungamiriri muindasitiri. Asi chii chaizvo chinonzi simbi isina ngura? Uye nei ichikosha kwauri? Ngationgororei kupatsanurwa kwezvinhu, maitiro ekugadzira, uye mashandisirwo ezvigadzirwa izvi zvinoshamisa.
Chidimbu chesimbi isina ngura chinogadzirwa nekumonera mapepa matete esimbi isina ngura kuita macoil kana maplate. Anopatsanurwa zvichienderana nekuumbwa uye hunhu, 201 ne304 zviri zviviri zvezvinonyanya kushandiswa. Chidimbu chesimbi isina ngura che201 chinozivikanwa nekugona kwaro kugadzira zvakanaka uye kuramba ngura zvine mwero, zvichiita kuti chive chakakodzera kushandiswa kunoenzanisa simba uye kushanda zvakanaka kwemari. Kune rumwe rutivi, chidimbu chesimbi isina ngura che304 chinopa kuramba ngura kwakanyanya uye chinowanzo shandiswa munzvimbo dzine zvinodiwa zvakanyanya zvehutsanana uye kugara kwenguva refu. Saka, kungave uri kutsvaga sarudzo inodhura zvishoma kana mhinduro yepamusoro, Jindalai inogona kusangana nezvaunoda.
Chidzitiro chesimbi isina ngura chinodzivirirwa zvakanyanya pakupisa, uye chinodzivirirwa nekuchinja kweganda kaviri kupfuura simbi yakajairika pa900.℃; kuramba kwayo kupisa kunowedzera nekukurumidza, kunyanya sezvo tembiricha ichidzikira; uye chiyero cheoxide pasimbi isina ngura chakakora uye chakaoma kubvisa. Uyezve, vashandisi vane zvinodiwa zvakanyanya zvekururama kwehukuru hwesimbi isina ngura uye kunaka kwenzvimbo yacho. Saka, tekinoroji yekupisa yekugadzirisa simbi isina ngura inoda michina yakawanda uye tekinoroji yekugadzira.
Zvino, ngatitaurei nezvemaitiro ekugadzira simbi isina ngura. Zvese zvinotanga nekusarudza zvinhu zvakagadziriswa, izvo zvinozonyungudutswa muchoto chemagetsi. Mushure mekunyunguduka, simbi inoitwa nenzira dzakasiyana-siyana, dzinosanganisira kukanda, kutenderedza kupisa, uye kutenderedza kunotonhora. Maitiro ekutenderedza kupisa anotenderedza simbi kuita strip, ukuwo kutenderedza kunotonhora kuchiwedzera kunatsiridza ukobvu uye kupedzisa kwepamusoro. Pakupedzisira, strip inopfuudzwa kuti ibvise kushushikana kwemukati uye kuvandudza hunhu hwayo hwemakanika. Iyi inzira yakaoma, asi ndiyo chaiyo nzira iyi inoita kuti chigadzirwa chisvike pamhando yepamusoro.—nekuti kuJindalai, hatingogadziri simbi isina ngura chete; tinogadzira tambo yega yega nekungwarira.
Kana usati wajaira mashandisirwo esimbi isina ngura, saka chii chaizvo chinoshandiswa? Mashandisirwo esimbi isina ngura akasiyana-siyana uye anonakidza. Kubva kuindasitiri yemotokari (inoshandiswa mumasisitimu eutsi uye zvikamu zvechivakwa) kusvika kuindasitiri yekuvaka (sechinhu chinosimbisa kongiri nezvikamu zvekuvaka), mashandisirwo esimbi isina ngura haana magumo. Uyezve, indasitiri yezvekudya nezvinwiwa inoshandisa zvakanyanya 304 stainless steel strip kugadzira michina inosangana nezvinodiwa zvehutsanana. Saka, kungave uri kugadzira mota kana michina yekicheni, simbi isina ngura inogona kuita basa rakakosha.
Chidzitiro chesimbi isina ngura chinopenyawo mukugadzira uye runako. Chinowanzo shandiswa pakushongedza senge machira, zviratidzo, uye fenicha. Chitarisiko chemazuva ano chesimbi isina ngura chinogona kusimudzira magadzirirwo enzvimbo chero ipi zvayo, zvichiita kuti ive inodiwa nevagadziri vezvivakwa nevagadziri. Pamusoro pezvo, chidzitiro chesimbi isina ngura hachingoparadzi ngura chete, asi chinongonaka chete asiwo chinogara kwenguva refu. Ndiani angadai akafunga kuti chinhu chakareruka sesimbi isina ngura chingave chakasiyana-siyana kudaro?
Muchidimbu, nyika yesimbi isina ngura yakakura uye yakasiyana-siyana, uye Jindalai Steel Group Co., Ltd. yagara iri mutungamiri mumhando yepamusoro uye hunyanzvi. Kunyangwe uchida simbi isina ngura inodhura 201 kana simbi isina ngura 304 yekushandisa pamhando yepamusoro, Jindalai ine hunyanzvi uye zvigadzirwa zvinogutsa zvaunoda. Saka, nguva inotevera yaunoda simbi isina ngura, yeuka kuti mhando ndiyo inonyanya kukosha; Jindalai yakazvipira kukupa zvigadzirwa zvepamusoro. Pamusoro pezvose, munyika yesimbi isina ngura, chinonyanya kukosha haisi simbi pachayo chete, asiwo hunyanzvi hwayo hwepamusoro.
