Zvidzitiro zvegrate of cermitall composite composite muchina unosanganisira makumi maviri nemashanu Pakati pavo, kuumbwa kwemakemikari ekupisa-kupokana neyekuita: C zvisingasviki kana kuenzana ne2,0%, Si8 26%, CAO1.0 ~ 4.0%, tio21.0 ~ 3.0%, fe2o30.5 ~ 2.0%, p2o51 ~ 0.5%, Alkali simbi oxides 1.0 ~ 1.5%.
Irate ine zvakanakira kupokana naAbrasion, kuramba, oxidation kuramba uye kudzikisira kwakanyanya kwekuramba kweCeramic uye kuomarara kwakanaka kwezvinhu zvesimbi. Mukuwedzera, iyo ine hunhu hwekudzikira kwehasha kusawirirana uye kurema kwechiedza zvichienzaniswa nesimbi yesimbi. Zvinogona zvakare kuita kuti troley yekuchengetedzeka seyakawedzera kuchengetedza simba
Zvikamu zvina zveGrate zviri seinotevera:
I. High chromium cast iron grate
Nekuda kwehuwandu hukuru hwechromures mukudziya kwakanyanya, cr203 film dhizaini yakaumbwa pamusoro peakakwirira cast cast dhizaini, iyo inodonha maitiro eiyo exidation kubva kune ekunze oxidation. Naizvozvo, ruzhinji rwechromium yakakwira mitsetse yesimbi ine yakanaka kupisa kupesana uye oxidation kuramba. Nekuda kwekunetseka kwakanyanya, marara zviri nyore kuitika pamusoro peiyo yemukati mehodhi, saka kuora kweiyo (fe, cr)
Maviri, akajairwa cast iron basket bar
Pamberi pa1980, nekuda kwekugona kusati kwatadza kwemidziyo inotadza, zvishandiso zvakakura, kushandiswa kwemapeni zvinonyanya kutemwa kurira simbi, iyi mhando yerudzi inobvisa hupenyu hupfupi hwebasa, kushandiswa kukuru. Kana grey rakaraswa simbi iri oxidized, denderedzwa resimbi oxide firimu rinoumbwa pamusoro pechiso, icho chiri fe203, fe304 uye teo kubva kunze kuenda mukati. Pane huwandu hukuru hwemakomba muefudzi, uye simbi uye okisijeni ioni nyore nyore kuburikidza neFo. Uye zvakare, iyo yekunze yeiyo oxide yefirimu firimu fe203 yakasununguka uye yakatsemuka, iri nyore kuputira. Naizvozvo, iyo nzvimbo yemukati yemhando yemufirimu isiri-alloy ikakanda simbi haina kudzivirira, uye kuita kwebasa kune murombo kwazvo. Gare gare, si yakawedzerwa kuGrey Ride Sed Simbi, uye yakaumbwa makomendi ehupfumi, uye akaumbwa dense makomputa muzvinhu zvekunyepedzera muzvikamu zvekutanga, izvo zvinogona kudzivirira oxidation. Iyo oxidation kuramba yesimbi-yakarongedza simbi inowedzera kuwedzera kwezvinhu zvakaudzwa, asi nekuwedzera kweSilicon zvemukati, simba rekukanda simbi dzinodzikira. Kupisa kudziya kuraswa matanda esimbi ari pakati nepakati silicon zvichibva pane grey cyray cast iron inogadzirwa munyika yedu, w (si) iri mu4,5% -5.5,5%. Nekuti grirafite iri mune ino yakasunganidzwa zvakabatanidzwa, inoita sechiteshi cheokisijeni kuti ipinde simbi, iyo inomhanya iyo oxidation chiyero. Yakajairwa cast iron labyrinth mitsetse hazviwanzo kushandiswa uye zvakanyanyisa kusarudzika.
Matatu, akawanda akawandisa akakwira chromium alloy basket bar
Kunyangwe iyo yakakwira mauto eChromium ikakanda Strip Strip ine zvakanaka oxidation kuramba, ine zvimwe zvikanganiso zvakadai sesimba rakaderera, kutambudzika kusarongeka uye kupwanyika kuri nyore. Uye nekuda kwesimbi isina murombo. Mari yekupisa-kuramba bar ine nickel yakashandisa kunze kwenyika yakanyanya kukwirisa. Zviri mukati meCr paZG9511 Simbi Grate inoshandiswa neThougang machina fekitori muna 1995 iri pamusoro peiyo Simbi inobviswa, uye huwandu hwakakodzera hwe ti, b, re, re uye zvimwe zvinhu zvinowedzerwa. Zviri mukati meCr203 mune oxidizing layer yakakwira zvakanyanya kupfuura yertcr25ni, uye Rexides inosanganisirwawo. Compact chimiro, hapana maburi uye maburi, kusanganiswa kwakanaka nesangano rakabatana, dense. Sangano rakakosha reRTCR25ni is & Gamma 9511 p, uye iyo Matrix yeZG9511 iri & alpha {NA} p, no & rarr; & gamma; Iyo matrix yakagadzikana panguva yekutendeuka kwechikamu.
Ina, kupisa-kuramba ductile iron grate
Nekuti graphite mukati meNodular simbi iri wega kugoverwa, hapana chiteshi cheokisijeni kupinda simbi, saka huwandu hwekukura hwakaderera pane grey cylat sedon, iyo application iri nani pane grey cast simbi. Kuchine gakava rakakura pakati pehukuru hwechromium rakamisikidza tsvimbo dzesimbi dzakatanga mumakore achangopfuura, asi nekuda kwekushomeka kwekushambadzira, kusimudzirwa kwakaderera, kuchiri kushandiswa mumarori madiki uye epakati.
