Imikhiqizo yethu yaziwa kabanzi futhi yethenjwa ngabasebenzisi futhi ingahlangabezana ngokuqhubekayo nezidingo zezomnotho nezenhlaloI-Roller Ephansi, TRACK ROLLER, Izingxenye ze-Undercarriage, Ngeshabhu ethuthukisiwe, ithimba labaklami abaqeqeshiwe kanye nesistimu yokulawula ikhwalithi eqinile, esekelwe ekupheleni okuphakathi kuya phezulu okumakwe njengendawo yethu yokumaketha, imikhiqizo yethu ithengiswa ngokushesha ezimakethe zaseYurophu nezaseMelika ngemikhiqizo yethu efana ngezansi kweDeniya, Qingsiya kanye Yisilanya.

Isingeniso esifushane:

I-Ductile iron, eyaziwa nangokuthi i-ductile cast iron, i-nodular cast iron, i-spherical graphite iron, i-spherical graphite cast iron kanye ne-SG iron, iwuhlobo lwensimbi exutshwe ne-graphite eyatholwa ngo-1943 nguKeith Millis.Nakuba izinhlobo eziningi zensimbi ekhonjiwe zibuthakathaka ekuqineni nasekuqineni, i-iron ductile inomthelela omkhulu kakhulu kanye nokumelana nokukhathala, ngenxa yokufakwa kwayo kwama-nodular graphite.I-Ductile iron ayiyona into eyodwa kodwa iyingxenye yeqoqo lezinto ezingakhiqizwa ngezinhlobonhlobo zezakhiwo ngokulawulwa kwe-microstructure yazo.Isici esivamile esichaza leli qembu lezinto zokwakha ukuma kwegraphite.Kuma-ayina ama-ductile, i-graphite isesimweni samaqhuqhuva esikhundleni sama-flakes njengasensimbi empunga.Nakuba ama-graphite flakes abukhali adala amaphuzu okugxilisa ingqondo ngaphakathi kwe-metal matrix, ama-nodule ayindilinga avimbela ukwakhiwa kwemifantu, ngaleyo ndlela anikeze i-ductility ethuthukisiwe enikeza ingxubevange igama layo.

I-Austempered ductile iron (ADI; okungukuthi, i-austenite tempered[7]) yatholwa ngeminyaka yawo-1950s kodwa yathengiswa futhi yazuza impumelelo eminyakeni ethile kamuva.Ku-ADI, isakhiwo se-metallurgical sisetshenziswa ngenqubo eyinkimbinkimbi yokwelapha ukushisa.

Ukwakheka

Ingxenye enkulu (%) ye-ferritic ductile iron castings[8]

Ezinye izinhlobo ze-iron ductile ngokuvamile zinenani elincane lesulfure.

Ikhabhoni, 3.2–3.60%

I-silicon, 2.2–2.8%

I-Manganese, 0.1–0.2%

I-Magnesium, 0.03–0.04%

I-Phosphorus, 0.005–0.04%

Isibabule, 0.005–0.02%

Ithusi, <0.40%

Insimbi, ibhalansi

Ama-elementi afana nekhopha noma ithini angase angezwe ukuze kwandiswe amandla futhi anikeze amandla ngesikhathi esifanayo kwehliswe i-ductility.Ukumelana nokugqwala okuthuthukisiwe kungafinyelelwa ngokufaka i-15-30% yensimbi ku-alloy ngamanani ahlukahlukene e-nickel, ithusi, noma i-chromium.

I-silicon njengengxenye yokwakheka kwe-graphite ingathathelwa indawo yi-aluminium ukuze inikeze ukuvikeleka okungcono kwe-oxidation.[9]

I-HONGDA Ductile iron castings:

Ekuqaleni kuka-2021, i-HONGDA yakha imboni entsha ukwethula izinto zokusebenza kanye nomugqa wokukhiqiza we-Ductile Iron Casting.
1. Okubalulekile: I-QT450#-10 kanye nezinga le-Spheroidization lingaphezu kweleveli III ukuze uthole ikhwalithi enhle yokulingisa ukusekela isicelo sakho.
2. Ulayini wokukhiqiza ozenzakalelayo ukuze ufinyelele ukusebenza kahle okuphezulu kanye nokukhiqizwa kwamandla amakhulu, ama-550T/Inyanga, ukubuyisela isidingo sakho esiphuthumayo.
3.Izinhlelo zokusebenza: i-ductile iron casting yekhololo ye-roller, ubakaki abangenzi lutho kanye nokunye okufana nezingxenye zokulingisa ngaphakathi kuka-70KGS. Irola yethrekhi enezingxenye ezibunjwe ngokunembayo, ukwelapha ngokushisa okucophelela kanye nohlelo lokuvala impilo yonke, ama-roller aqinisekiswa impilo ende. kusuka kunsimbi eqinile eqinile futhi yakhelwe ukumelana ne-bellmouthing.Wonke ama-roller aphatha iwaranti yabakhiqizi.
