Yakakwira silicon corrosion inodzivirira cast iron yevharuvhu zvinhu

Yakakwira silicon corrosion inopesana nesimbi yakakandwa yevharuvhu iyi chiyero inotsanangura zvinodiwa zvehunyanzvi, nzira dzekuyedza, sampling uye mitemo yekuongorora, yekumaka mucherechedzo, kurongedza, kuchengetedza uye zvekufambisa zvinodiwa zveyakakwira silicon corrosion inodzivirira simbi yakakandwa. Iyi chiyero inoshanda kune yakakwira silicon corrosion inodzivirira cast iron ine silicon yemukati yegumi, 00% ~ 15. 00%. Madhirowa anoratidza zvakatemwa, maumbirwo uye zvimiro, mirairo yekukandira yekuchenesa, mifananidzo inoratidza hukuru hwakakosha uye inopa kushivirira kwese kwedimensional. Kana uyo anokumbira akapa modhi, saizi yekukanda ichaenderana nehukuru hwakachengeterwa modhi. Kunyangwe bvunzo ye hydraulic ichidikanwa, uye kana zvakadaro, kudzvanywa kweyedzo uye kuvuza kunobvumidzwa kunofanirwa kuratidzwa. chiyero Iyi chiyero inotsanangudza zvinodiwa zvehunyanzvi, nzira dzekuyedza, sampling uye mitemo yekuongorora, yekukandira mucherechedzo, kurongedza, kuchengetedza uye zvekufambisa zvinodiwa zveyakakwira silicon corrosion inodzivirira simbi yakakandwa. Iyi chiyero inoshanda kune yakakwira silicon corrosion inodzivirira cast iron ine silicon yemukati yegumi, 00% ~ 15. 00%. Normative reference document Matemu ari mumagwaro anotevera anova mazwi eChiyero ichi nereferensi iyi. Pazvinyorwa zvemazuva, zvigadziriso zvese zvinotevera (kusanganisa erratum) kana zvigadziriso hazvishande kune iyi Standard; zvisinei, mapato ari muchibvumirano pasi peichi Chiyero anokurudzirwa kuongorora kuwanikwa kwe*** shanduro dzemagwaro aya. Kune mareferensi asina kunyorwa, mavhezheni avo anoshanda kune iyi mwero. Ruzivo rweOdha Ruzivo rwunotevera rweodha ruchapihwa neanokumbira: a) Iyo yakajairwa nhamba yekuuraya. b) yakakwira silicon yakakanda simbi brand. c) Nhamba yekukandwa. d) Kukanda uremu. e) Madhirowa anoratidza zvakatemwa, maumbirwo uye zvimiro, mirairo yekukandira yekuchenesa, mifananidzo inoratidza hukuru hunokosha uye inopa kushivirira kwese kwese. Kana uyo anokumbira akapa modhi, saizi yekukanda ichaenderana nehukuru hwakachengeterwa modhi. Sarudzo muhurongwa ruzivo: a) Chimiro chekurapa kwekupisa kwekukanda panguva yekusununguka; b) Kungave kupa mudiwa gwaro rekuongorora makemikari; c) Kana bvunzo yekukotama ichidikanwa; d) Kana bvunzo ye hydraulic ichidikanwa, uye kana zvakadaro, kudzvanywa kwekuyedza uye kuvuza kunobvumidzwa kunofanirwa kuratidzwa. e) Chero kurongedza kwakakosha, kumaka, nezvimwe. Nzira yekugadzira Kunze kwekunge yatsanangurwa neimwe nzira, nzira yekunyungudika uye maitiro ekukanda anozotemwa neMutengesi. Tekinoroji inodiwa Giredhi uye kemikari yemhando yepamusoro yesilicon corrosion inodzivirira simbi yakakandwa Iyo giredhi yekutaura nzira yeyakakwira silicon corrosion isingagadzike simbi yakakandwa inoenderana nezvinodiwa zveGB/T 5612, iyo yakakamurwa kuita mamakisi mana. High silicon corrosion resistant iron iron giredhi uye inoenderana makemikari anoumbwa ona Kugamuchirwa kwesilicon yakakwira corrosion resistant iron cast ichabva pamakemikari ayo, ayo anozoenderana nezviri paTable 1. Mechanical properties The mechanical properties of high silicon corrosion resistant cast. simbi haiwanzotorwa sehwaro hwekugamuchirwa. Kana zvichidiwa neanokumbira, tsvimbo yekuedza ichaiswa pamuedzo wekukotama kuti ione simba rayo rekukotama uye kutsauka, uye mhinduro dzebvunzo dzichaenderana nezvinodiwa zveTafura 2. (2) High silicon corrosion resistant iron iron imhando ye brittle metal material, mukugadzirwa kwemaitiro ekukanda kwayo haifaniri kunge yakapinza uye yakapinza chikamu chekuchinja. Iyo geometry uye saizi yekukanda ichaenderana nedhirowa kana tekinoroji zvinodiwa zveanoda. Kana iyo Demander isina zvakakosha zvinodikanwa pane dimensional kushivirira kwekukanda, izvo zvinoenderana neGB/T 6414 zvinozoteverwa. Kukandwa kunofanirwa kucheneswa, kucheneswa zvakanyanya "nyama", kubvisa kudira mvura, bhonzo repakati, jecha revhu uye mukati megomba residue, nezvimwewo. Zvakasara zvekudururira simiti, musono unovhara, spike inobhururuka uye kuchena kwemukati kwemukati kunoenderana nemufananidzo. kana zvinodiwa zvehunyanzvi zvemutengi kana chibvumirano cheodha pakati pemapato maviri. Pamusoro: high silicon corrosion resistant iron of valve material (I) Test rod Muyedzo wekupeta wesilicon corrosion isingagadzike iron iron inogashira inotora bhara rekuyedza rimwechete rine dhayamita re30mm uye kureba kwe330mm pasina machining. Tsanangudzo dzayo dzinoratidzwa muMufananidzo 1. Chikamu: millimeter Cherechedza: Iyo yakakurudzirwa saizi yekukanda yebhari yekuyedza inofanira kunyoroveswa kusvika ku540 ℃ mu mold isati yadonha jecha, uye kushushikana kwasara kunofanira kubviswa pamberi pekukotama bvunzo. Iyo imwechete yekukanda bvunzo tsvimbo ichadirwa mubatch imwechete yesimbi yemvura sekukanda (yekutanga uye yekupedzisira mapakeji haazoshandiswe). Muchiumbwa chimwechete chekukanda, matanda akawanda ekuedza anogona kudururwa panguva imwe chete, uye nzira yekutarisa inoratidzwa mumufananidzo 2. Chikamu: millimeter Geometric uye dimensional tolerances High silicon corrosion resistant iron iron imhando yebrittle metal material, uye inopinza. cross section transition haifaniri kudiwa mukugadzirwa kwemaitiro ekukanda kwayo. Iyo geometry uye saizi yekukanda ichaenderana nedhirowa kana tekinoroji zvinodiwa zveanoda. Kana iyo Demander isina zvakakosha zvinodikanwa pane dimensional kushivirira kwekukanda, izvo zvinoenderana neGB/T 6414 zvinozoteverwa. Kutsauka kwehuremu Kana pasina chakakosha chinodiwa pakukanda uremu kutsauka, izvo zvinoenderana neGB/T 11351 zvinoteverwa. Hunhu hwepamusoro Hushasha hwepamusoro hwekukandwa hunoenderana neGB/T 6061.1 kana dhirowa yevanoda kana zvinodiwa zvehunyanzvi. Kukandwa kunofanirwa kucheneswa, kuchekwa zvakanyanya "nyama", kubvisa kudira mvura, bhonzo repakati, jecha revhu uye mukati megomba residue, nezvimwewo. Zvakasara zvekudururira riser, musono unovhara, spike inobhururuka uye kuchena kwemukati kwemukati kunoenderana nemufananidzo. kana zvinodiwa zvehunyanzvi zvemutengi kana chibvumirano cheodha pakati pemapato maviri. Kukanganisa kwekukanda Hapazovi nekukanganisa kwekukanda kunoderedza simba uye kukuvadza kutaridzika kwechigadzirwa. Izvo zvinobvumirwa kukanganisa uye nzira yekupfeka ichabvumirana nemapato. Kupisa kurapwa High silicon cast iron inowanzoiswa mukupisa kurapwa mamiriro (kubvisa zvakasara kushushikana). Kune zvidiki zvekukanda zvechimiro chakareruka, kana zvikapihwa sekukanda, mapato ese ari maviri anofanira kubvumirana. Castings ichaitwa kurapwa kwekupisa kubvisa kusara kunetseka. Kana iye anokumbira asina zvakakosha zvinodiwa, kukanda kunogona kuitwa nenzira dzinotevera: Kukanda jecha kudonha mune dzvuku rinopisa mamiriro, nekukasira kubvisa zvese zvemechani kuramba kune mahara shrinkage yekukanda, kubvisa kukanda risers, tsvuku inopisa inokanda yakananga mukurapa kwekupisa. choto preheating yakakwira kupfuura 600 ℃, yobva yadziya zvishoma nezvishoma, tembiricha yakadzikira ye870 ℃. Pane tembiricha yakakwira kupfuura 870 ℃, zvinoenderana nehukuru hwakakura hwemadziro ehukasha, nguva yekuvharira inofanira kunge iri 1.h/25mm, asi nguva shoma yekuvharisa haifanirwe kunge iri pasi pe2h. Zvadaro inotonhodzwa nekumhanya kusingapfuuri 55 ℃/15 min. Yakatonhodzwa kusvika ku205 ℃ nechoto uye mweya wakatonhodzwa pakudziya kwakajairika. Chinodiwa chakakosha Kana iye anodiwa aine zvinodiwa zvekuongororwa magineti, kuongororwa kwe ultrasonic, X-ray kuyedzwa, nezvimwewo, iye anoda uye anokumbira anotaurirana nekuita zvinoenderana neGB/T 9444, GB/T 7233 uye GB/T. 5677 zvichiteerana. Nzira yekuyedza Kuongorora Kemikari Yakajairwa, inotaridzika kana dzimwe nzira dzekushandisa dzinogamuchirwa asi dzinofanirwa kugadzirwa kuti dzibudise mhedzisiro imwe chete. Zvakajairwa sampling nzira dzekuongorora kemikari dzichaitwa zvinoenderana neGB/T 20066. Iyo arbitrated ongororo yekabhoni, silicon, manganese, sarufa uye phosphorus mumakemikari ekuumbwa kwakaverengerwa maererano neGB/T 20123 kana GB/T 223.69,GB/ T 223.60, GB/T 223. 58 kana GB/T 223. 64,GB/T 223. 3 kana GB/T 223. 59 kana GB/T 223. 61,GB/T 223. 53 Chrome, kiyi, kupindirana kwemhangura ongororo ichaitwa zvinoenderana neGB/T 223.11 kana GB/T 223.12,GB/T 223.26,GB/T 223.18 kana GB/T 223.19 kana GB/T 223.53, zvichiteerana. Iyo spectral sampling nzira inoitwa maererano neGB/T 5678 uye GB/T 14203. Iyo spectral yekuongorora nzira ichaitwa maererano neGB/T 20125.
