I-silicon ephezulu ekwazi ukumelana nentsimbi yentsimbi yevalvu

I-silicon ephezulu enganyangekiyo kwintsimbi yevalvu Lo mgangatho uxela iimfuno zobugcisa, iindlela zovavanyo, iisampulu kunye nemithetho yokuhlola, ukuphawula, ukupakishwa, ukugcinwa kunye neemfuno zothutho ze-silicon ephezulu ekwazi ukumelana nentsimbi. Lo mgangatho usetyenziswa kwi-silicon ephezulu ye-corrosion resistant cast cast kunye nomxholo we-silicon we-10, 00% ~ 15. 00%. Imizobo ebonisa iinkcukacha, iimilo kunye nemilinganiselo, imiyalelo yokucoca, imizobo ebonisa imilinganiselo engundoqo kunye nokubonelela konke ukunyamezela kwe-dimensional. Ukuba umceli ubonelela ngemodeli, ubungakanani bokuphosa buya kuhambelana nobukhulu obugcinelwe imodeli. Ingaba uvavanyo lwe-hydraulic luyafuneka, kwaye ukuba kunjalo, uxinzelelo lovavanyo kunye nokuvuza okuvumelekileyo kufuneka kuboniswe. uluhlu Lo mgangatho uxela iimfuno zobugcisa, iindlela zovavanyo, iisampulu kunye nemithetho yokuhlola, ukuphawula, ukupakishwa, ukugcinwa kunye neemfuno zothutho ze-silicon ephezulu ekwazi ukumelana nentsimbi. Lo mgangatho usebenza kwi-silicon ephezulu ekwazi ukumelana nentsimbi kunye nomxholo we-silicon we-10, 00% ~ 15. 00%. Uxwebhu lwereferensi yesiqhelo Imigaqo kula maxwebhu alandelayo iba yimiqathango yalo Mgangatho ngokubhekisele kulo Mgangatho. Kwiingcaphulo zomhla, zonke izilungiso ezilandelayo (kungabandakanywa ierratum) okanye izilungiso azisebenzi kulo Mgangatho; nangona kunjalo, amaqela kwisivumelwano phantsi kwalo Mgangatho ayakhuthazwa ukuba aphande ngokufumaneka kwe-*** iinguqulelo zala maxwebhu. Kwiimbekiselo ezingabhalwanga umhla, iinguqulelo zabo ziyasebenza kulo mgangatho. Ulwazi lwe-odolo Olu lwazi lulandelayo lomyalelo luya kunikwa ngumfaki-sicelo: a) Inani elimiselweyo lokwenziwa. b) uphawu lwentsimbi ephezulu yesilicon. c) Inani lokusaswa. d) Ubunzima bokuphosa. e) Imizobo ebonisa iinkcukacha, iimilo kunye nemilinganiselo, imiyalelo yokucoca, imizobo ebonisa imilinganiselo engundoqo kunye nokunyamezela konke. Ukuba umceli ubonelela ngemodeli, ubungakanani bokuphosa buya kuhambelana nobukhulu obugcinelwe imodeli. Izinketho kwi-oda yolwazi: a) Ubume bonyango lobushushu lokuphosa ngexesha lokunikezelwa; b) Ingaba uza kubonelela umfaki-sicelo ngengxelo yohlalutyo lwemichiza; c) Ingaba uvavanyo lokugoba luyafuneka; d) Ingaba uvavanyo lwe-hydraulic luyafuneka, kwaye ukuba kunjalo, uxinzelelo lovavanyo kunye nokuvuza okuvumelekileyo kufuneka kuboniswe. e) Nakuphi na ukupakishwa okukhethekileyo, ukuphawulwa, njl njl. Indlela yokuvelisa Ngaphandle kokuba kuchazwe ngenye indlela, indlela yokunyibilikisa kunye nenkqubo yokuphosa iya kumiselwa nguMboneleli. Imfuno yobugcisa IBanga kunye nokwakheka kweekhemikhali ze-silicon corrosion resistant cast cast iron Indlela yokubonakalisa i-high silicon corrosion resistant cast iron cast ihambelana nemigaqo ye-GB/T 5612, eyahlulahlulwe yaba ngamabakala amane. Umgangatho we-silicon ephezulu ekwaziyo ukumelana nentsimbi kunye nokwakheka kweekhemikhali ezihambelanayo bona Ukwamkelwa kwe-silicon ephezulu ekwaziyo ukumelana nentsimbi kuya kusekelwa kubume bayo bekhemikhali, eya kuthi ithobelane namalungiselelo eTheyibhuli yoku-1. Ipropathi yobutshini intsimbi ngokuqhelekileyo ayithathwa njengesiseko sokwamkelwa. Ukuba ifunwa ngumfaki-sicelo, intonga yovavanyo iya kufakwa kuvavanyo lokugoba ukumisela amandla ayo okugoba kunye nokuphambuka, kwaye iziphumo zovavanyo ziya kuhambelana nezibonelelo zeThebhile 2. brittle metal impahla, kuyilo lwesakhiwo castings yayo akufuneki ibe bukhali kwaye elibukhali cross icandelo inguqu. Ijometri kunye nobukhulu be-castings iya kuhambelana nomzobo okanye iimfuno zobugcisa zomfaki-sicelo. Ukuba i-Demander ayinayo iimfuno ezikhethekileyo kwi-dimensional tolerance of casting, imimiselo echaphazelekayo ye-GB/T 6414 iya kulandelwa. Ukuphosa kufuneka kucocwe, kulungiswe ngakumbi "inyama", ukususa isikhuphukeli esigalelayo, umbindi wethambo, isanti yodongwe kunye nentsalela yomngxuma ongaphakathi, njl. njl. okanye iimfuno zobugcisa zomthengi okanye isivumelwano somyalelo phakathi kwamaqela amabini. Phezulu phezulu: i-silicon ephezulu ekwaziyo ukumelana nentsimbi yevalvu (I) Intonga yovavanyo Uvavanyo olugobayo lwe-silicon ephezulu ekwaziyo ukumelana nentsimbi yamkela ibha yovavanyo enye enobubanzi obuyi-30mm kunye nobude be-330mm ngaphandle komatshini womatshini. Iimpawu zayo ziboniswe kuMzobo 1. Iyunithi: i-millimeter Qaphela: Ubungakanani obuphakanyisiweyo bokuphosa bebha yokuvavanya kufuneka bupholile ukuya kwi-540 ℃ kwi-mold ngaphambi kokuwa kwesanti, kwaye uxinzelelo oluseleyo kufuneka lususwe ngaphambi kovavanyo lokugoba. Intonga yokuvavanya enye iya kugalelwa kwibhetshi enye yentsimbi engamanzi njengoko kugalelwa (izipakethe zokuqala nezokugqibela aziyi kusetyenziswa). Kwi-mold casting efanayo, iintonga ezininzi zokuvavanya zingagalelwa ngexesha elifanayo, kwaye inkqubo yereferensi iboniswe kuMfanekiso 2. Iyunithi: i-millimeter yejometri kunye ne-dimensional tolerances. inguqu yecandelo lomnqamlezo akufuneki ifuneke kuyilo lolwakhiwo lweecastings zayo. Ijometri kunye nobukhulu be-castings iya kuhambelana nomzobo okanye iimfuno zobugcisa zomfaki-sicelo. Ukuba i-Demander ayinayo iimfuno ezikhethekileyo kwi-dimensional tolerance of casting, imimiselo echaphazelekayo ye-GB/T 6414 iya kulandelwa. Ukuphambuka kobunzima Ukuba akukho mfuneko ekhethekileyo yokuphosa ubunzima, imimiselo echaphazelekayo ye-GB / T 11351 iya kulandelwa. Umgangatho womphezulu Uburhabaxa bomphezulu becastings buya kuhambelana ne-GB/T 6061.1 okanye imizobo yomfaki-sicelo okanye iimfuno zobugcisa. Ukuphosa kufuneka kucocwe, kulungiswe ngakumbi "inyama", ukususa isikhuphukeli esigalelayo, umbindi wethambo, isanti yodongwe kunye nentsalela yomngxuma ongaphakathi, njl. njl. okanye iimfuno zobugcisa zomthengi okanye isivumelwano somyalelo phakathi kwamaqela amabini. Isiphene sokuphosa Akuyi kubakho ziphene zokuphosa ezinciphisa amandla kunye nokonakalisa inkangeleko yemveliso. Iziphene ezivumelekileyo kunye nendlela yokugqoka iya kuvunyelwa ngamaqela. Unyango lobushushu I-silicon ephezulu ephoswe ngentsimbi idla ngokusetyenziswa kwimeko yonyango lobushushu (ukususa uxinzelelo olushiyekileyo). Kwiicastings ezincinci zemilo elula, ukuba zinikezelwe njengesamente, omabini amaqela kufuneka avumelane. Iicastings ziya kunyangwa ubushushu ukususa uxinzelelo olushiyekileyo. Ukuba umfaki-sicelo akanazo iimfuno ezikhethekileyo, ukuphosa kunokwenziwa ngezi ndlela zilandelayo: Ukuphosa isanti kwindawo eshushu ebomvu, kuphelisa ngokukhawuleza konke ukuchasana komatshini ukuncitshiswa kwamahhala, ukuphelisa ukukhupha ukukhupha, ukuphosa okubomvu okutshisa ngokuthe ngqo kunyango lobushushu. I-oven preheating ngaphezulu kwe-600 ℃, emva koko ifudumeza kancinci, iqondo lobushushu elisezantsi le-870 ℃. Kwiqondo lobushushu elingaphezulu kwe-870℃, ngokobungakanani obukhulu bodonga lwe-castings, ixesha lokugquma kufuneka libe yi-1.h/25mm, kodwa ixesha lokugquma elisezantsi alifanele libe ngaphantsi kwe-2h. Emva koko ipholiswe ngesantya esingekho ngaphezulu kwe-55℃/15 min. Ipholiswe kwi-205 ℃ kunye neziko kunye nomoya opholileyo kubushushu obuqhelekileyo. Imfuno ekhethekileyo Ukuba umfaki-sicelo uneemfuno zovavanyo lwamasuntswana omagnetic, uvavanyo lwe-ultrasonic, uvavanyo lwe-X-ray, njl. njl., umfaki-sicelo kunye nomfaki-sicelo uya kuthetha-thethana kwaye aphumeze ngokuhambelana namalungiselelo e-GB/T 9444, GB/T 7233 kunye ne-GB/T 5677 ngokulandelelanayo. Indlela yovavanyo Uhlalutyo lwemichiza Iindlela eziqhelekileyo, ezibonwayo okanye ezinye izixhobo zamkelekile kodwa kufuneka zibekwe emgangathweni ukuvelisa iziphumo ezifanayo. Iindlela eziqhelekileyo zesampulu zohlalutyo lweekhemikhali ziya kwenziwa ngokwe-GB / T 20066. Uhlalutyo lwe-arbitrated ye-carbon, i-silicon, i-manganese, isulfure kunye ne-phosphorus kwi-chemical composition yabalwa ngokwe-GB / T 20123 okanye i-GB / T 223.69, GB / T 223.60, GB/T 223. 58 okanye GB/T 223. 64,GB/T 223. 3 okanye GB/T 223. 59 okanye GB/T 223. 61,GB/T 223. 53 Chrome, isitshixo, ulamlo lobhedu uhlalutyo luya kwenziwa ngokungqinelana ne-GB/T 223.11 okanye i-GB/T 223.12,GB/T 223.26,GB/T 223.18 okanye i-GB/T 223.19 okanye i-GB/T 223.53, ngokulandelanayo. Indlela yokulinganisa i-spectral yenziwa ngokwe-GB / T 5678 kunye ne-GB / T 14203. Indlela yokuhlalutya i-spectral iya kwenziwa ngokwe-GB / T 20125.
