Ungayisombulula njani isiphene sentlabathi kwimveliso ye-Iron engwevu isebenzisa itekhnoloji ye-SIMOL SIFANY?

Ingxaki enkulu yesanti kwimveliso ye-27 ye-kg grey bil inyibiliki ye-pilley isebenzisa itekhnoloji ye-stand yefilimu sisiphene esiqhelekileyo kwinkqubo yokuphosa. Isanti enamathelayo inokunyusa kakhulu umthwalo wokucoca umthwalo, yonakalise umgangatho wokuphoxeka, ukonyusa iindleko, kwaye kunokukhokelela ekufuduseni. Ukusombulula le ngxaki, uphando olucwangcisiweyo kunye noqeqesho kufuneka lwenziwe kwimiba emininzi efana nesanti edityanisiweyo, i-parameters yenkqubo, uyilo lwentsimbi kunye nokusebenza. Ezi zinto zilandelayo zineengcinga kunye nemilinganiselo:

I-1. Imiba esemgangathweni enesanti yamehlo:

a. Umgangatho ophantsi weSand Sand: I-SIO ephantsi ye-Sio Ukuhanjiswa kwesahlulo esingangqinelaniyo: Amasuntswana entlabathi ahlangane kakhulu (njenge> 70 Mesh), izithuba phakathi kwamasuntswana entlabathi zinkulu, kwaye i-iron etyhidiweyo inamathela ekuthandeni kwesanti yoomatshini. Ukuba amasuntswana e-Sand Alungile Ubume obuhlwempuzekileyo: Isanti kunye ne-coundar ephezulu (i-polygonal) inesiphene esisezantsi kunye ne-Polygonity ephezulu kunesanti ejikelezayo, esenza ukuba kube lula ukuthoba i-forfaces kunye nesanti.

b. Umsebenzi ongapheliyo wefilimu Ukunyanga okungaphelelanga

Ungayisombulula njani kwimveliso yokwenene

Khetha isanti ephezulu esemgangathweni: Eyona nto iphambili kufuneka inikezwe isanti yohlaza kunye ne-SIO ₂ Umxholo (≥ 97%), ukungcola okuphantsi, kunye nokudityaniswa kwe-angshing ye-70/140 ye-70/100 okanye i-50/11 mesh. Ukuphucula intsebenzo yesanti esenzayo: Ukunyusa umxholo we-resin: ngokufanelekileyo ukwandisa inani le-fenolin yongezwa (E.G. ukuya kwi-2,3-2.8%) ukuqinisekisa ukwenziwa kwefilimu ye-resin efanelekileyo. Ukongeza i-filler filler: ukongeza ii-consers ezinokuphucula ububi kwaye kunciphise utyekelo lweSanti enamagqabi: i-zircocia powder: kodwa eyona ndleko iphakamileyo. Ingathanga indawo yesanti yoqobo okanye isetyenziswe njengesongezelelo (5-20%). I-Chromite Powder: Isithintelo esiphakamileyo, i-Coandes Eres Adsko Ukwanda kolwandiso, kunye nokuxhathisa okuhle kwi-Peetic. I-Olivine Powder: Uzinzo lobushushu obuphezulu kunye nokunyangwa kwi-alkaline slasion. I-Alumina AlumIna AlumIca Popder / Mullite Powder: Iphucula amandla obushushu obukhulu. Sebenzisa i-REPINOP ephezulu: Khetha i-resin yenzelwe ngokuthe ngqo isanti yesanti kunye nokuchasana komlilo okuphezulu, amandla aphezulu, kunye nokuveliswa kwegesi ophantsi (njengokuguqulwa kwegesi Qinisekisa unyango olwaneleyo: Ukulawula ngokungqongqo ukwenziwa kwenkqubo yenkqubo (ubushushu obubunjiweyo kudla ngokuphakathi kwe-220-260 ℃, kwaye ixesha lokunyanga lilungiswa ngokobungakanani be-resin iphilisiwe ngokupheleleyo.

2. Izizathu zenkqubo yokuthulula kunye neeparamitha zenkqubo

a. Iqondo lokuhlala eligqithileyo: I-iron engwevu inomzimba ofanelekileyo, kunye nobushushu obugqithisileyo (njenge> 1450 ℃) iya kuphucula kakhulu i-thermatics yentsimbi ukuya entlabathini. Amaqondo obushushu aphezulu akwazi ukonakalisa ifilimu ye-resin.

b. Isantya sokugalela kakhulu: Isantya sokugada ngokugqithileyo sanyusa amandla agudileyo kwi-molten poltity yodonga, eyonakalisayo, inyusa umngcipheko we-molten kwi-culls kwi-culls kwi-GARS kwi-GARS kwi-GARS kwi-GARS kwi-GARS kwi-GARS kwi-GARS kwi-GARS kwi-GARS kwi-GARS kwi-GARS kwi-GARS kwi-GARS kwi-GARS kwi-GARS kwi-GARS kwi-GARS kwi-GARS kwi-GARS kwi-GARS kwi-GARS kwi-GARS kwi-GALSEES.

c. Intloko egqithisileyo (ukuphakama okuphezulu): Uxinzelelo lwensimbi olugqithisileyo luya kunyanzelisa i-iron etyhidiweyo ukuya kungena ngokulula iipores phakathi kwamasuntswana esanti.

d. Impembelelo ye-Golden Eraction ye-Iron: Ikhabhoni ephezulu (CE): Umxholo we-Scickon oPhezulu (CE> 4.3-4.5) kuya kuphucula i-fluency yentsimbi kwaye anyuse utyekelo lwayo lokulinganisa. Umyinge ophantsi we-mn / s: Xa umxholo wesalfure kakhulu okanye umxholo we-manganese ongonelanga, okuncinci kwe-MNS yenziwa, engahambelani nefilimu yefilimu ye-Ox Kucetyiswa ukulawula umyinge we-MN / s phakathi kwe-8-12. I-Phosphorus yomxholo: phosphorus ephezulu (P> 0.1%) iya kunciphisa uxinzelelo lomhlaba lwe-iron enyibilikisiweyo, yandisa i-Holly, kwaye ikhuthaze ukungenisa. I-oxidation: I-oxidation egqithisileyo yentsimbi enyibilikisiweyo inokuvelisa ukubandakanywa okungaphezulu kwe-oxide kubandakatri, echaphazela ukwenziwa kwefilimu yokukhusela kumphezulu.

Isisombululo-Lawula ngokungqongqo amaqondo obushushu: ngelixa uqinisekisa ukuzaliswa ngokupheleleyo kwaye ukuphepha ukufakelwa okubandayo, zama ukunciphisa amaqondo obushushu kangangoko kunokwenzeka. Kwi-Hilogram eyi-27 ye-phy inyibiliki yentsimbi, ukulawula amaqondo obushushu phakathi kwe-1360-15-1400 ℃ (ehlengahlengiswa ngobukhulu bomhlaba, kunye nomda ophantsi weyona njongo iphambili. Ithemometha kufuneka idityaniswe ngokuchanekileyo! Yenza isantya sokuthulula: Yamkela isantya esigudileyo nesimodareyitha. Cinga ngokusebenzisa inkqubo yokuthulula yokugalela ngeengxowa ze-buffer okanye inaliti esezantsi ukunciphisa ifuthe ngqo kwi-mold cavity. Ukucutha ukuphakama kwe-Inkn: Ngelixa uqinisekisa ukuzalisa, zama ukunciphisa ukuphakama kweNdebe yeSprue okanye ukusebenzisa iSprue ephumli. Yenza ubume be-molten yesinyithi: Ngelixa udibana neepropathi zoomatshini (ubukhulu becala) yeinkcazelo, ngokufanelekileyo ukunciphisa i-carbon elinganayo (CE) (njengethagethi ye-silicon. Qinisekisa i-Mn / 10 eyoneleyo (≥ 10): Ngokuhlengahlengisa i-Scrap / intsimbi yentsimbi okanye ukongeza intsimbi ye-manganese, qinisekisa ukuba umxholo we-manganese wanele ukuba nesalfure kunye ne-MNS. Ukulawulwa kwe-oxidation yentsimbi ye-molten: Yenza i-Fooculace Doculac yoNyango (ukuphucula i-morphology ye-graphy, ngokungathanga ngqo ichaphazela umphezulu), kuphephe ukufuduswa okungaphezulu okanye ukuncipha kobushushu obuphezulu kunokubangela i-oxidation.

a. Ukunganeli kwesanti yesanti

b. Amaqondo obushushu aphezulu kakhulu: Ngexesha lokuveliswa okuqhubekayo, ubushushu obubunjiweyo buqokelela kakhulu (> 280 ℃), bubangele ukuqiniseka kwesanti enamagqabi ngaphambili okanye ngexesha lokuqhuma, ukufana kwentlabathi yesanti.

c. Engasetyenziswanga (okanye isetyenziswe ngokungafanelekanga) Ukuphosa i-comance: Ukuphazamiseka okungafunekiyo: Ukuphononongwa kweemfuno eziphezulu okanye iindawo ezinobuqhetseba kwi-Sallation Desion, hayi ukusebenzisa i-caily enganyangekiyo kunobungozi obunganyangekiyo. Umgangatho ophantsi othi: Ukunganyangeki komlilo okuphantsi, ukunqunyanyiswa okungalunganga, ukunqunyanyiswa okuthe tye okanye ukungalingani. Ukomisa akonelanga: Ukudibana kuthulula ngaphambi kokuba womiswe ngokupheleleyo, kwaye amanzi avela kumaqondo obushushu aphezulu, avelisa uxinzelelo olunokutyhala i-iron entweni okanye ebangela ukuba i-teel icime.

d. Ukususwa komzimba / ukuphatha ukonakala: I-Sand I-Sunds ifakwe ngexesha lenkqubo yokususwa, ukuphatha, kunye nendibano eyaziwayo, ekhokelela kumphezulu.

e. Uyilo olungalunganga lwesikhundla seSprue: I-Sprue ijonge ngqo kudonga lwe-cavity okanye udonga oluthambileyo, lubangela i-il elona sit-typern lid to ntloko liqhume ngokuthe ngqo kumphezulu wesanti

Isisombululo-Yandisa inkqubo yokwenza izinto: qinisekisa uxinzelelo olwaneleyo lwesanti kwaye ubambe ixesha lokuqinisekisa ukuba isanti ye-Told / Core yenziwe kunye neyunifomu. Hlaziya rhoqo kwaye ugcine isisu ukuze uqiniseke ukuba iplagi engapheliyo. Lawula amaqondo obushushu omnyama, kwaye ukuba kukho imfuneko, yongeza i-Word Cheages yeqondo lokuphola kwezixhobo (ezinjengeendlela zokupholisa amanzi) okanye zandise umjikelo wemveliso. Ukusetyenziswa okunyanzelekileyo kwengubo ekumgangatho ophezulu kunye nokusetyenziswa ngokuchanekileyo.
