Simbi yakakosha, kureva, simbi yakakosha, ndiyo inonyanya kukosha mhando yesimbi inoshandiswa mumaindasitiri mazhinji ehupfumi hwenyika, semichina, mota, indasitiri yemauto, makemikari, midziyo yemumba, ngarava, zvekufambisa, njanji uye maindasitiri ari kubuda.Simbi yakakosha chiratidzo chakakosha chekuyera kana nyika inogona kuve imba yesimbi.
Special-chinangwa simbi inoreva zvimwe zvikamu zvinoshanda pasi pemamiriro akakosha uye zvine zvakakosha zvinodiwa nesimbi, senge yemuviri, makemikari, mechaniki nezvimwe zvinhu.
Special performance steels zvakare akakosha emhando alloy simbi.Aya masimbi anoreva masimbi ane electromagnetic, optical, acoustic, thermal uye electrochemical zviito uye mabasa.Inowanzo shandiswa isimbi isina tsvina, simbi inodzivirira kupisa, magetsi esilicon simbi, simbi yakachena yemagetsi uye akasiyana magineti alloys (magineti akapfava, senge magineti alloys, elastic alloys, expansion alloys, thermal double alloys, resistance alloys, primary battery materials, etc. .)..
Simbi isina simbi inodaidzwa nekuda kwekunaka kwayo kuita ngura, uye zvikamu zvayo zvikuru zvealloying ichromium uye nickel.Chromium ine kugadzikana kwemakemikari yakakwira uye inogona kugadzira firimu rakaoma uye rakaomarara rekuchenesa mune oxidizing medium;uyezve, kana chromium yemukati ichipfuura 11.7%, iyo electrode mukana weiyo alloy inogona kuwedzera zvakanyanya, nekudaro zvinobudirira kudzivirira kuwedzera oxidation yealloy.Nickel zvakare mufambisi.Kuwedzerwa kwenickel kune chromium simbi kunogona kuvandudza kushorwa kweiyo alloy mune isiri-oxidizing media.Kana zviri mukati mechromium uye nickel zvikaramba zviripo, iyo yakaderera iyo kabhoni musimbi, zviri nani kuramba ngura.
Iyo corrosion resistance yesimbi isina tsvina inoenderanawo nekufanana kweiyo matrix chimiro.Kana iyo yunifomu alloy yakasimba mhinduro yakaumbwa, iyo corrosion rate yesimbi mu electrolyte inogona kunyatso kuderedzwa.
Austenitic Stainless simbi ndeye chromium-nickel series simbi isina tsvina ine imwechete austenitic chimiro.Iyo ine yakanaka corrosion resistance, yakaderera tembiricha kuoma, kumanikidza kugadzirisa uye welding processability, isiri-magnetic, uye inoshandiswa zvakanyanya seyakadzika tembiricha simbi uye yakaderera tembiricha simbi inoshanda mune corrosive media.Non-magnetic simbi;ferritic Stainless simbi inonyanya kuve nechromium, iyo inoshandura chikamu panguva yekudziya uye kutonhora, uye inowanzoshandiswa kupfeka-resistant zvinhu munitric acid uye nitrogen fetiraiza maindasitiri;martensitic Stainless simbi ine yakakwira kabhoni yemukati uye yakanaka kuoma.A martensitic structure inowanikwa.Simbi iyi ine kusimba kwakanaka uye yakaderera kabhoni yemukati, uye inogona kushandiswa kugadzira inokanganisa-inopikisa zvikamu zvinoshanda muzvinoodza media;high kabhoni inoshandiswa kugadzira zvitubu, mabheya, mashizha ekuvhiya, nezvimwewo;ine zvikamu zviviri zvakasanganiswa chimiro che austenite uye ferrite.Simbi isina tsvina yematrix ndeye duplex simbi isina tsvina, ine zvakanakira simba rakakwirira, kusimba kwakanaka, uye kuramba kune intergranular corrosion.Pakati pavo, 00Cr18Ni5Mo3Si2 simbi inonyanya kushandiswa mukugadzira kupisa kupisa uye condensers mukunatsa mafuta, fetiraiza, pepa, petroleum, kemikari uye mamwe maindasitiri, uye 0Cr26Ni5Mo2 inoshandiswa mukugadzira midziyo yemvura yegungwa;molybdenum, niobium, lead, mhangura uye zvimwe zvinhu muchikamu chakaomeswa zvinovaita Mushure mekudzima uye kurapwa kuchembera, ine simba rakakura uye kuoma, uye inonyanya kushandiswa kugadzira zvitubu, washer, mabhero, nezvimwe.
Simbi yemagetsi, inozivikanwawo sesilicon simbi, isimbi-silicon binary alloy ine kabhoni inodzika isingasviki 0.05%.Iyo ine hunhu hwekurasikirwa kwesimbi diki, diki yekumanikidza simba, yakakwirira magineti permeability uye magineti induction intensity, uye ndeimwe yeanowanzo shandiswa akapfava magineti zvinhu (yenguva pfupi kana inodzokororwa magineti).Zvinhu zvikuru zvinokanganisa kushanda kwesimbi yemagetsi ndeyemakemikari uye maitiro.Silicon ine simba guru pane magineti emhando yesimbi yemagetsi.Kana 3.0% Si yakawedzerwa kune simbi yakachena, iyo magnetic permeability inowedzerwa ne 1.6-2 nguva, iyo hysteresis kurasikirwa inoderedzwa ne40%, iyo resistivity inowedzera ne4 nguva (iyo inogona kuderedza eddy ikozvino kurasikirwa), uye iyo yose. kurasikirwa kwesimbi kunoderedzwa.Yakapetwa kaviri, asi kuoma uye kusimba zvinowedzerwawo Zvinokosha.Kazhinji iyo silicon yemukati haipfuure 4.5%, zvikasadaro yakanyanya kuoma uye yakaoma kugadzirisa.Kuvapo kwekusvibiswa kunokuvadza (N, C, S, O, nezvimwewo) kunokonzera kukanganisa kwelatisi yesimbi, kuwedzera kushushikana, uye kukanganisa magnetization process, saka zvirimo zvetsvina zvinofanira kunyatsodzorwa.
Silicon simbi inonyanya kushandiswa mumaindasitiri emagetsi emagetsi akadai semotor, transformers, midziyo yemagetsi, uye zviridzwa zvemagetsi.Mazhinji akakungurutswa kuita 0.3, 0.35, 0.5 mapepa, kusanganisira kupisa uye kutonhora kukunguruka.chando chakakunguruka
