Pfungwa yesimbi: Simbi ialloy yesimbi, kabhoni, uye nhamba diki yezvimwe zvinhu.Simbi ingot, billet, kana simbi yakatsikiswa-yakashandiswa kuita maumbirwo, saizi, uye zvivakwa zvatinoda.Simbi chinhu chakakosha pakuvaka kwenyika uye kuzadzikiswa kwezvinhu zvina zvemazuva ano.Inoshandiswa zvakanyanya uye ine zvakasiyana-siyana.Zvinoenderana neakasiyana-siyana-chikamu maumbirwo, anowanzo kupatsanurwa muzvikamu zvina: profiles, mahwendefa, pombi, uye zvigadzirwa zvesimbi.Kufambisa kugadzirwa uye kurongeka kwesimbi Supply uye kuita basa rakanaka mukushanda uye manejimendi, yakakamurwa kuita njanji inorema, njanji yakareruka, yakakura chikamu simbi, yepakati chikamu simbi, diki chikamu simbi, inotonhora-yakaumbwa chikamu simbi, yepamusoro-mhando. chikamu simbi, waya tsvimbo, yepakati uye gobvu simbi ndiro, nhete simbi ndiro, yemagetsi silicon simbi pepa, strip simbi, hapana Seam simbi pombi, welded simbi pombi, simbi zvigadzirwa, uye mamwe marudzi.
Simbi ialloy yesimbi, kabhoni, uye zvidiki zvezvimwe zvinhu.Simbi isina tsvina kana corrosion-resistant alloy simbi ine 10.5% kana kupfuura chromium-goridhe zvirimo itemu rinozivikanwa rerudzi urwu rwesimbi.Izvo zvinofanirwa kuyeukwa kuti simbi isina tsvina hairevi kuti simbi haizove ngura kana marara, asi kungoti inopokana zvakanyanya nekuora pane alloys asina chromium.Mukuwedzera kune chromium simbi, zvimwe zvinhu zvesimbi senge nickel, molybdenum, vanadium, nezvimwewo zvinogonawo kuwedzerwa kune alloy kuti ichinje midziyo yesimbi yealloy, nokudaro ichigadzira simbi isina tsvina yemagiredhi akasiyana uye zvivakwa.Kunyatsosarudzwa kwemapanga akagadzirwa nesimbi isina tsvina ine midziyo yakanyatsokodzera, zvichienderana nechinangwa uye nzvimbo yekushandiswa, zvakakosha pakuvandudza kushanda uye mukana wekubudirira kwebasa rakapiwa.Kubatsira kwezvinhu zvakasiyana-siyana zvesimbi mumapanga.Zvichitaurwa zviri nyore: Simbi ndeye alloy yesimbi uye kabhoni.Zvimwe zvinoshandiswa zviripo kusiyanisa zvinhu zvesimbi.Simbi dzakakosha dzakanyorwa pazasi muhurongwa hwearufabheti, uye dzine zvinotevera zvinongedzo:
Carbon - Inowanikwa mumasimbi ese uye ndiyo inonyanya kuomesa chinhu.Kuti tibatsire kuwedzera kusimba kwesimbi, tinowanzoda simbi yebanga-giredhi kuti ive nekabhoni inodarika 0.5%, uyewo high-carbon steel.
Chromium - Inowedzera kuramba kupfeka, kuomarara, uye zvakanyanya kukosha corrosion kuramba, inopfuura 13% inoonekwa sesimbi isina tsvina.Pasinei nezita rayo, simbi yose ichaita ngura kana isina kuchengetedzwa zvakanaka.
Manganese (Manganese) - chinhu chakakosha chinobatsira pakusikwa kwechimiro chechimiro, uye chinowedzera kusimba, kusimba, uye kupfeka kusagadzikana.Internal deoxidation yesimbi panguva yekupisa kupisa uye crimping inowanikwa mune akawanda banga uye shear steels kunze kweA-2, L-6, uye CPM 420V.
Molybdenum (Molybdenum) - carbonizing agent, inodzivirira simbi kubva pakuita brittle, inochengetedza simba resimbi pakupisa kwakanyanya, inowanikwa mumashizha akawanda esimbi, mhepo inoomesa simbi (semuenzaniso A-2, ATS-34) inogara iine 1% kana kupfuura Molybdenum saka vanogona kuomesa mumhepo.
Nickle - Inochengetedza simba, kusagadzikana kwekuora, uye kuoma.Inoonekwa muL-6\AUS-6 neAUS-8.
Silicon - Inobatsira kuwedzera simba.Kufanana nemanganese, silicon inoshandiswa kuchengetedza simba resimbi panguva yekugadzirwa kwayo.
Tungsten (Tungsten) - Inowedzera abrasion kuramba.Musanganiswa we tungsten uye chikamu chakakodzera chechromium kana manganese chinoshandiswa kugadzira simbi yepamusoro.Nhamba yakawanda ye tungsten inowanikwa mu-high-speed simbi M-2.
Vanadium - Inowedzera kupfeka kusagadzikana uye ductility.Carbide yevanadium inoshandiswa kugadzira simbi ine mitsetse.Vanadium iri mumhando dzakawanda dzesimbi, pakati payo M-2, Vascowear, CPM T440V, uye 420VA ine huwandu hukuru hwevanadium.Musiyano mukuru pakati peBG-42 neATS-34 ndewekuti yekutanga ine vanadium.
