"Kuvimbika, Kuvandudza, Kusimba, uye Kubudirira" inogona kunge iri fungidziro inoenderera yebhizinesi redu kusvika kwenguva refu kugadzira pamwe chete nevatengi mukuwirirana uye purofiti yepombi mhinduro inopa. Isu tine hesitori hombe yeCr Mo alloy simbi pombi kuzadzisa kufona kwevatengi vedu uye zvinodiwa. Nevashandi vakadzidza, vane hunyanzvi uye vane simba, isu tave nebasa rezvinhu zvese zvekupa pombi mhinduro. Nehukuru hwemhando yepamusoro uye sevhisi yakakura, tiri kunanga kuchinangwa chekuve mumwe wevatengesi vepombi mhinduro huru munyika. Isu tinoteerera zvakanyanya kune mhinduro kubva kune vatengi vedu uye tinopa mhinduro ipapo. Iwe unozonzwa pakarepo sevhisi yedu ine hunyanzvi uye yekuteerera.

Nezve pfuma yeCr Mo pipe, kune zvakawanda zvesimbi zvinhu zvinoikanganisa. Hukama huri pakati pemichina yepombi uye main metal element sepazasi:

Carbon (C): Carbon yemukati musimbi inowedzera, goho poindi, kusimba kwesimba uye kuoma kunowedzera, asi purasitiki uye hunhu hunodzikira. Kana iyo kabhoni yemukati ichipfuura 0.23%, iyo welding yesimbi inodzikira, saka kana ikashandiswa kushinha Iyo kabhoni yemukati yepasi-alloy structural simbi kazhinji haipfuure 0.20%. Yakakwira kabhoni yemukati inoderedzawo kushomeka kwemuchadenga kwesimbi, uye simbi yakakwira-kabhoni muyadhi yakashama iri nyore kuita ngura; uyezve, kabhoni inogona kuwedzera kutonhora brittleness uye kuchembera kunzwa kwesimbi.
Silicon (Si): Silicon inowedzerwa sechinhu chinoderedza uye deoxidizer mukugadzirwa kwesimbi, saka simbi yakaurayiwa ine 0.15-0.30% silicon. Silicon inogona kuvandudza zvakanyanya muganho elastic, goho poindi uye tensile simba resimbi, saka inoshandiswa zvakanyanya sesimbi elastic. Kuwedzera kwehuwandu hwesilicon kunoderedza kushanda kwesimbi.
Manganese (Mn). Mukugadzira simbi, manganese yakanaka deoxidizer uye desulfurizer. Kazhinji, simbi ine 0.30-0.50% manganese. Manganese inogona kuwedzera kusimba uye kuoma kwesimbi, kuwedzera kuoma kwesimbi, kunatsiridza kupisa kushanda kwesimbi, uye kuderedza kushanda kwesimbi.
Phosphorus (P): Kazhinji, phosphorus chinhu chinokuvadza musimbi, icho chinowedzera kutonhora kwesimbi, kushatisa kushanda kwewelding, inoderedza plastiki, uye inokanganisa kutonhora kwekukotama. Naizvozvo, iyo phosphorus yemukati musimbi inowanzodikanwa kuti ive isingasviki 0.045%, uye chinodiwa chemhando yepamusoro simbi yakaderera.
Sarufa (S): Sulfur zvakare chinhu chinokuvadza mumamiriro ezvinhu akajairika. Gadzira simbi inopisa brittle, kuderedza simbi ductility uye kuoma, uye kukonzera makatsemuka panguva yekugadzira nekukunguruka. Sulfur zvakare inokuvadza kune welding performance, inoderedza corrosion resistance. Naizvozvo, iyo sulfur yemukati inowanzodiwa kuti ive isingasviki 0.045%, uye chinodiwa chemhando yepamusoro simbi yakaderera. Kuwedzera 0.08-0.20% sulfur kune simbi inogona kuvandudza machinability, uye inowanzonzi simbi yemahara.
Vanadium (V): Kuwedzera vanadium kusimbi kunogona kunatsiridza zviyo zvechimiro uye kugadzirisa simba uye kuoma.
Niobium (Nb): Niobium inogona kunatsa zviyo uye kunatsiridza welding kuita.
Mhangura (Cu): Mhangura inogona kuvandudza simba uye kuoma. Izvo zvisingabatsiri ndezvokuti zvinowanzoita brittleness inopisa panguva yekushanda kunopisa, uye mhangura yemhangura musimbi yakarasika inowanzokwirira.
Aluminium (Al): Aluminium inowanzoshandiswa deoxidizer musimbi. Hushoma hwealuminium hunowedzerwa kusimbi kunatsa zviyo uye kugadzirisa kuoma kwesimba.
