Ongorora kana banga rokushandisa, chinhu chekutanga kufunga chakapinza.
Iyo inopinza dhigirii yezvinhu zvikuru ndiko kuoma kwesimbi (

Ngatitii kune mapanga maviri, rimwe rakagadzirwa nesimbi yakapfava, rimwe rakagadzirwa nesimbi yakaoma.
Kuzvikuya zvakapinza kwazvo, kuti zvimwe zvakafanana?
Mhinduro ndeyokuti kwete, nokuti simbi yakapfava inopinza nokukurumidza.
Saka kuramba uchiramba wakapinza kunoenderana zvakanyanya nekugona kwekuoma kwesimbi, ndicho chinhu chikuru chinotonga kushanda kwebanga.
Pamusoro pekuona budiriro yekicheni banga simbi kuomarara uye ngura kuramba, kupfeka kuramba, kuomarara, kuoma uye kuomarara kunopesana, kuomarara,

Kupfeka kusagadzika uye kusagadzikana kwekuora kunowanzo kupesana, chinhu chinogona kuita kuti kicheni irambe yakapinza kwenguva yakareba asi zvichanetsa kugaya.
Simbi isina tsvina uye zvimwe zvigadzirwa zvesimbi, hapana mutsauko wakakosha pakati chete nekuda kweiyo yakakwira chromium zvirimo, iyo chrome oxide inoumbwa munzvimbo yesimbi kudzivirira iron oxide, kana iri nguva yakareba bubble mvura inogona kuita ngura.
420 akateedzana simbi isina tsvina akajairwa masupamaketi anotengesa yakaderera-yekupedzisira banga rekicheni rine chinangwa-yakawanda, yakachipa uye yakanakisa ngura kuramba, asi iyo kabhoni yemukati yakadzikira zvakanyanya, saka kuomarara kwakaderera hakupfuuri makumi mashanu neshanu, zvakada kuenzana neyedu yepamba-yekupedzisira-inowanzo shandiswa. matatu chrome simbi (

X50CrMoV15 ashkenazi mainstream simbi yekicheni banga, yakanaka kuita ngura, kuoma, asi yakagomara nekukurumidza.
Asi kugadzirisa kwakanaka hakugone kucheka kudonha, zvakaenzana nepamba yedu inowanzoshandiswa 5 chrome simbi banga.
Ehe 5 chrome simbi inoshanda zvirinani pane yakajairwa simbi pachayo, mushure memugadziri wakasarudzika kupisa kurapwa zvakare ine kumwe kusimudzirwa, asi izvo zvinongedzo zviripo kune general performance.
Mumba mune kuoma kwakafanana simbi yekicheni banga rinoshandiswa kucheka mbabvu dzakakora, huku chena yakachekwa, chop chop izvo nyama yenguruve yakanaka kwazvo, asi miriwo yekucheka nyama zviri pachena inonzwa kupfuura simbi yekuJapan.
Iyo Japanese kicheni banga isina simbi, pano chete nekuda kwekusiyana.

Chengetedza dhigirii rakapinza zvakanaka, kuoma kwakakwira, zvakare hakusi nyore kuita ngura, asi yakakwira kabhoni yemukati isingasviki 5 chrome simbi inodzivirira.
Iko kune hunhu hunenge hwakaderera-kupera VG1 simbi, kuoma, anenge makumi matanhatu.

Icho chigadzirwa chemazuva ano metallurgical tekinoroji, imhando yesimbi poda seyakabikwa, kuburikidza nekutsikirira uye sintering nzira dzekugadzira dzakasiyana siyana zvigadzirwa.
Nekuti hupfu simbi yepasirese gore negore inobuda chete zviuru makumi mashanu zvematani, ine tekinoroji yehunyanzvi yakaomesesa vashoma chete vevagadziri, yakakwirira pamusoro pemutengo hongu.
