Umbhobho wentsimbi we-Nodular cast
Iinkcukacha zeMveliso
Imibhobho yentsimbi yentsimbi eyi-nodular iyimibhobho yentsimbi edityanisiweyo, enesiseko sentsimbi kunye neempawu zentsimbi, ngoko ke igama labo.I-graphite kwimibhobho ye-iron ductile ikhona kwifom ye-spherical, kunye nobukhulu obuqhelekileyo bamabakala angama-6-7.Ngokumalunga nomgangatho, inqanaba le-spheroidization lemibhobho yentsimbi etyhidiweyo kufuneka ilawulwe kumanqanaba angama-1-3, kunye nesantya se-spheroidization ≥ 80%.Ngoko ke, iimpawu zomatshini wezinto eziphathekayo ngokwazo ziphuculwe, ziphethe isiseko sentsimbi kunye neempawu zetsimbi.Emva kwe-annealing, i-microstructure ye-ductile iron mibhobho i-ferrite kunye nenani elincinci le-pearlite, eneempawu ezintle ze-mechanical, ngoko ke ikwabizwa ngokuba yi-cast iron steel pipes.

1.Ukusebenza kokumelana noxinzelelo lwangaphakathi:
I-Centrifugal ductile iron inondoqo wentsimbi kunye nokusebenza kwentsimbi, ngoko ke imibhobho yentsimbi ene-ductile inokusebenza okugqwesileyo kokhuseleko kunemibhobho eyenziwe kwezinye izinto.Uxinzelelo oluyilelweyo lokusebenza luphezulu kakhulu kunolo lwemibhobho eyenziwe kwezinye izinto, into ekhuselekileyo iphezulu kakhulu, kwaye uxinzelelo olunokuthi lubekho.
amaxesha amathathu oxinzelelo lokusebenza.
2.Ukusebenza kokuxhathisa uxinzelelo lwangaphandle:
Ukuxhatshazwa koxinzelelo oluphezulu kunokuphepha imfuno yebhedi yombhobho kunye nekhava yokukhusela, okwenza iibhobho ezibeka i-rellable kunye nezoqoqosho.
3. Umaleko wokuchasana nomhlwa wangaphakathi:
Uluhlu lwangaphakathi lwemibhobho ye-iron ductile ifakwe kwi-centrifugally ngodaka lwesamente.Ukufakwa kwesamente kuhambelana nomgangatho wehlabathi we-ISO4179, uqinisekisa ukuba udaka lomelele kwaye lugudileyo.Ukugquma kweemoto akuyi kuwa okanye kubi, kwaye ubukhulu bayo buqinisekisa ukuba amanzi okusela adluliselwe kwimibhobho afumana ukhuseleko oluhle.
4.Ukhuseleko lokwaleka:
Ukutshizwa kwe-zinc kwimibhobho yentsimbi edonsa amanzi kunokukhusela imibhobho ngokusebenzayo ngesiphumo se-electrochemical ye-zinc ne-iron.Ngepeyinti ephezulu ye-chiorinated resin, imibhobho iya kufumana ukhuseleko olwandisiweyo lokuchasana nomhlwa.Ukutshizwa kwezinki kumphezulu wombhobho ngamnye akukho ngaphantsi kwe-130g/m², kwaye kuthobelana nomgangatho we-ISO8179.Sinokonyusa ubukhulu bokutshiza kwe-zinc okanye ukutshiza i-zinc kunye ne-aluminium alloy layer ngokwemfuno yabathengi.
Iimbonakalo
Umbhobho wentsimbi luhlobo lombhobho wentsimbi.Ngokomgangatho, inqanaba le-spheroidization yemibhobho yentsimbi etyhidiweyo kufuneka ilawulwe kumanqanaba e-1-3 (izinga le-spheroidization> 80%), ngaloo ndlela iphucula iimpawu zomatshini wezinto ngokwazo, eziphethe isiseko sentsimbi kunye neempawu zentsimbi. .Umbhobho wentsimbi ye-annealed ine-metallographic ye-ferrite enexabiso elincinci le-pearlite, eneempawu ezilungileyo zoomatshini, ukusebenza kakuhle kwe-anti-corrosion, i-ductility elungileyo, isiphumo esihle sokutywinwa, ukufakwa lula, kwaye isetyenziselwa ukubonelela ngamanzi, ukuhanjiswa kwegesi. , ukuthuthwa kweoli, njl. kumashishini kamasipala kunye namashishini.
Kukho umlinganiselo othile wegraphite engqukuva esasazwe kwimatrix yeferrite kunye nepearlite.Ngokuxhomekeke kubukhulu obuqhelekileyo kunye neemfuno zokwandisa, umlinganiselo we-ferrite kunye ne-pearlite kwisakhiwo se-matrix siyahluka.Umlinganiselo wepearlite kwiidayamitha ezincinci azikho ngaphezu kwe-20%, ngelixa i-diameter enkulu ilawulwa ngokubanzi malunga ne-25%.
Isicelo
Imibhobho yentsimbi exutyiweyo ifumaneka kuluhlu lweedayamitha ukusuka kwi-80mm ukuya kwi-1600mm kwaye ilungele ukuhanjiswa nokuhanjiswa kwamanzi aselwayo (ngokuhambelana ne-BS EN 545) kunye nogutyulo (ngokuhambelana ne-BS EN 598). , inokubekwa kuzo zonke iimeko zemozulu kwaye kaninzi ngaphandle kwesidingo sokuzaliswa kwakhona okukhethiweyo.Ukhuseleko lwalo oluphezulu kunye nokukwazi ukuhambelana nokuhamba komhlaba kwenza kube yinto efanelekileyo yokusetyenziswa kwemibhobho yoluhlu olubanzi lwezicelo.
