Kusarudzwa kwezvinhu zvakasvibirira
Iyo raw material kuravira kunofanirwa kuvandudza nekunakirwa kwendariramarudzi.Paunenge uchinyungudutsa ndarira isingakoshi, kana hutano hwekuchaja hwakavimbika, dzimwe nguva kushandiswa kwezvinhu zvekare kunogona kusvika 100%.Nekudaro, kuitira kuve nechokwadi chemhando yekunyunguduka uye kuderedza kuparara kwekupisa, kushandiswa kwechaji yakakamurwa zvakatsetseka senge akasiyana masawdust kana zinc chips haifanire kudarika 30%.Experimental surface: Paunenge uchishandisa 50% cathode copper uye 50% brass yekare zvinhu, inodiwa nguva yekunyungudutsa ndiyo yakareba uye kushandiswa kwesimba ndiko kwakanyanya.Kana iyo zinc ingot isati yapisa kusvika 100 ~ 150 ℃ uye ichidyiswa mumabheti, inobatsira zvikuru kuti inyaire uye inyauka mudziva rakanyungudutswa nekukurumidza, izvo zvinogona kuderedza kupisa kwekupisa kwesimbi.Kuwedzera hushoma hwephosphorous kunogona kuumba imwe elastic oxide film inoumbwa ne2ZnO.p2o2 pamusoro pedziva rakanyungudutswa.Kuwedzera shoma shoma yealuminium, yakadai se0.1% ~ 0.2%, inogona kuumba firimu rekudzivirira reAl2O3 pamusoro pemvura yakanyungudutswa, uye inobatsira kudzivirira uye kuderedza kuparara kwezinc uye kugadzirisa mamiriro ekukanda.Kana nhamba huru yezvigadzirwa zvekare zvichishandiswa kunyungudutsa ndarira, pre-muripo wakakodzera unofanirwa kuitwa kune zvimwe zvinhu zvine kurasikirwa kukuru kwekunyungudika.Semuenzaniso, pre-muripo wehuwandu hwezinc ndeye 0.2% kana ichinyungudutswa yakaderera-zinc ndarira, iyo pre-muripo wehuwandu hwezinc ndeye 0.4% -0.7% kana yepakati-zinc ndarira inonyungudutswa, uye pre-muripo wezinc i1.2% -2.0% kana yakakwira-zinc.
Melting process control
Iyo yakajairika kurongeka kwekuwedzera kana kunyungudutsa ndarira ndeye: mhangura, yekare zvinhu uye zinc.Paunenge uchinyungudutsa ndarira kubva musimbi yakachena zvigadzirwa, mhangura inofanira kutanga yanyungudutswa.Kazhinji, kana mhangura yanyungudutswa uye yakanyanyisa kusvika kune imwe tembiricha, inofanirwa kunyungudutswa zvakanaka (semuenzaniso nephosphorus) uye ipapo zinc inofanira kunyungudutswa.Kana iyo yekuchaja iine yekare bras charge, iyo yekuchaja sequence inogona kugadziridzwa zvinoenderana nemamiriro chaiwo akadai sehunhu hwezvikamu zvealloy uye rudzi rwechoto chekunyungudutsa.Nemhaka yokuti zvinhu zvekare pachazvo zvine zinc, kuitira kuti kuderedza kunyunguduka kwechizinc element, zvinhu zvekare zvendarira zvinowanzofanira kuwedzerwa uye kunyungudutswa pakupedzisira.Nekudaro, zvidimbu zvakakura zvechaji hazvina kukodzera kubhadharisa kwekupedzisira uye kunyungudika.Kana mhosva yacho yakanyorova, haifaniri kuwedzerwa zvakananga kune yakanyunguduka.Kana iyo yakanyorova yakawedzera pamusoro peimwe isina kunyungudika mutero, ichagadzira kuomeswa uye preheating nguva isati yanyungudutswa, izvo zvisingabatsiri chete kudzivirira kunyunguduka inhalation, asiwo kudzivirira dzimwe njodzi.Zinc yekuwedzera pane yakaderera tembiricha ndiyo musimboti unofanirwa kuteverwa mune dzinenge dzese nzira dzekunyungudutsa ndarira.Kuwedzera zinc pakupisa kwakadzika hakugone chete kuderedza kupisa kwekupisa kwe zinc, asiwo kubatsira kuchengetedzwa kwekunyungudika kushanda.Pakunyungudutsa ndarira mumoto-frequency iron-core induction furnace, kazhinji hazvifanirwe kuwedzera deoxidizer nekuti iyo inonyunguduka pachayo, kureva kuti, dziva rekunyungudutswa, rine zinc yakawanda.Zvisinei, kana kunyunguduka kwakashata, 0.001% ~ 0.01% phosphorus inogonawo kuwedzerwa maererano nehuremu hwose hwechaji yekubatsira deoxidation.Kuwedzera hushoma hwemhangura-phosphorus master alloy kune yakanyunguduka inogona kuwedzera fluidity yekunyunguduka isati yaburitswa kubva muchoto.Tichitora H65 brass semuenzaniso, kunyungudika kwayo i936°C.Kuti gasi nemagazini mukunyunguduka zviyangamire uye zvibudise nenguva, pasina kukonzera kuwanda kwe zinc uye inhalation yekunyunguduka, tembiricha yekunyunguduka inowanzodzorwa pa1060 ~ 1100 ° C.Tembiricha inogona kukwidziridzwa zvakakodzera kusvika 1080 ~ 1120 ℃.Mushure me "kupfira moto" 2 kusvika ku3 nguva, inokandwa mushanduri.Fukidza nemarasha akabikwa panguva yekunyunguduka, uye hupamhi hwevhavha yevhavha inofanira kunge yakakura kudarika 80mm.
