Ubunzima kunye neMilinganiselo yokuPhuculwa ekugaleleni amaTshala oBhedu obhedu

Ubunzima bokuphosa amatyholo e-tin bronze ikakhulu kubandakanya le miba ilandelayo:

1. Iziphene zokuphosa: Iziphene eziqhelekileyo kwi-tin bronze casting ziquka imingxuma, imingxuma, ukulunywa zizinambuzane okanye ubumnyama bendawo kwindawo yokuphosa, ukubila kwenkcenkceshe okanye ukubila okukhokelela, ukufakwa kwe-slag, ukwahlula, ukushwabana kwemingxunya, ukucutheka, ukuvala okubandayo, njl njl. ezi ziphene zinokubandakanya izinto ezininzi ezifana nokufunxwa komoya wengxubevange eqatha, ulawulo olungafanelekanga lokugalelwa ubushushu, ukufuma okugqithisileyo okanye umxholo wokungcola kwisanti ebumbayo, kunye noyilo olungenangqiqo lwenkqubo yokugalela.
2. I-Reverse segregation phenomenon: I-tin bronze ngokwayo ineempawu zokwahlula umva, oko kukuthi, inxalenye yokuqala ekhutshiweyo iqulethe umlinganiselo ophezulu we-tin-melting-point tin, kwaye inxalenye kamva iqulethe ixabiso elincinci le-tin. Lo mcimbi unokubangela ukuba amandla kunye nokumelana noxinzelelo lwamanzi lokuphosa kwehle.
3. Ingxaki yokushwabana: Ibronzi yenkcenkce inoluhlu olubanzi lobushushu obukhazimlayo, ijiya kwindawo encangathi, kwaye ithanda ukuba neziphene. I-Shrinkage iya kunciphisa iipropati zomatshini kunye nokuxinana kwe-casting, echaphazela ubomi bayo benkonzo kunye nokhuseleko.
4. Ulawulo lwenkqubo yokuphosa: Ukuphosaiihlahla zobhedu lwenkcenkceifuna ulawulo oluchanekileyo lweeparamitha zenkqubo ezifana nobushushu obunyibilikayo, isantya sokugalela, isantya sokupholisa, njl.njl. ukuqinisekisa umgangatho kunye nokuzinza kwee-castings. Ukongezelela, ukuyila kunye nokuchaneka kokuveliswa kwesikhunta nako kunempembelelo ebalulekileyo ekusebenzeni kwemveliso yokugqibela.
5. Ukukhethwa kwezinto eziphathekayo: Izinto eziphezulu zobhedu kunye nezinto ze-alloy zisisiseko sokuqinisekisa umgangatho wemveliso. Ngethuba lenkqubo yokuphosa, kuyimfuneko ukukhetha izinto ezifanelekileyo ze-alloy kunye nemilinganiselo ukuhlangabezana neempawu zomatshini kunye neemfuno zokumelana nokubola kwe-castings.

Amanyathelo okuphucula

Ngenxa yobunzima obungasentla, la manyathelo alandelayo anokuthathwa ukuze kuphuculwe umgangatho kunye nokusebenza kwamatyholo obhedu obhedu.
1. Lungiselela inkqubo yokuphosa: Ukunciphisa ukwenzeka kweziphene zokuphosa ngokuphucula inkqubo yokuthulula, ukulungelelanisa ukushisa okunyibilikayo kunye nesantya sokuthulula, kunye nokuphucula iimpawu zesanti yokubumba.
2. Ukuqinisa uyilo lokubumba kunye nokuveliswa: Ukuphucula imilinganiselo yoyilo kunye nokuchaneka kokuveliswa kwesikhunta ukuqinisekisa ukuchaneka komgangatho kunye nomgangatho womhlaba wokuphosa.
3. Lawula ngokungqongqo umlinganiselo wezinto eziphathekayo kunye nomxholo we-alloy element: Khetha izinto eziphezulu zobhedu kunye nezinto ze-alloy, kwaye ulawule ngokungqongqo umlinganiselo wabo kunye nomxholo wokuqinisekisa iipropati zomatshini kunye nokuxhathisa ukubola kwe-castings.
4. Yazisa ubuchwepheshe bokuphosa obuphambili: njengokuphosa kwe-centrifugal, i-vacuum suction casting kunye nezinye iindlela zobugcisa eziphuculweyo zokunciphisa iziphene zokuphosa kunye nokuphucula ukusebenza kwe-castings.

Ngamafutshane, ukuphosa i-tin bronze bushings kufuna uqwalaselo olubanzi lwezinto ezifana nokukhethwa kwezinto, inkqubo yokuphosa, uyilo lokubumba kunye nokuveliswa kokuqinisekisa umgangatho kunye nokusebenza kwee-castings.
