Ukuncipha ekulingisini kuyisici esibalulekile esithinta kakhulu ikhwalithi nobuqotho bomkhiqizo wokugcina. Ukuqonda izinhlobo ezahlukene zokuncipha ezihambisana nezinto ezahlukahlukene, njenge insimbifuthiInsimbi, kanye nezici ezibangela ukukhubazeka okufana nokushwabana kwezimbotshana nokuqhekeka okushisayo, kubalulekile ezenzweni ezisebenzayo zokuphonsa.
Ukuncipha ku-Cast Steel ne-Cast Iron
Lapho ukhuluma ngokuncipha, kubalulekile ukuhlukanisa phakathi kwezinto ezimbili eziyinhloko ezisetshenziswa ekubumbeni:insimbifuthiInsimbi. Zombili izinto ezisetshenziswayo zibonisa ukuncipha, kodwa izindlela namazinga angahluka.
I-Cast steel ngokuvamile ihlangabezana nokuncipha okuphelele cishe1.5% ukuya ku-2%kusukela ekuncibilikeni kwayo kuya ekuqineni kwayo. Lokhu kushwabana kubangelwa ngokuyinhloko ukufinyela okushisayo kwento njengoba iphola. Ngokuphambene, i-cast iron inezinga eliphezulu lokushwabana, ngokuvamile nxazonke2% ukuya ku-3%. Ukuncipha okwengeziwe ku-cast iron kungabangelwa ukwakheka kwayo, okuhlanganisa okuqukethwe kwekhabhoni ephezulu okuthinta ukuziphatha kwayo kokuqina.
Ukuncipha Kwangempela Kokusakaza
Ukuncipha kwangempela kubhekisela ekushintsheni kobukhulu obuphelele okutholwa ukusakaza kusuka kusimo sakho soketshezi kuya esimweni saso sokugcina esiqinile. Lokhu kungafaka kokubili ukuncipha kwevolumu ngesikhathi sokupholisa kanye nemiphumela yokuqiniswa. Idizayini efanele nokubalwa kwejiyomethri yokulingisa kubalulekile ukuze kuhlangatshezwane nalokhu kushwabana, njengoba ukwehluleka ukwenza kanjalo kungaholela ekungalungini kobukhulu kanye nezakhiwo zemishini ezisengozini.
Ama-Shrinkage Cavities kanye ne-Porosity
Izimbotshana zokuncipha, ezaziwa nangokuthi ama-shrinkage voids, zenzeka lapho uketshezi lwensimbi luhluleka ukugcwalisa isikhunta ngenxa yokungondleki okwanele ngesikhathi sokuqina. Lesi simo singaholela kumaphuzu abuthakathaka ekubumbeni, okwenza kube lula ukwehluleka ngaphansi komthwalo. Ngakolunye uhlangothi, i-porosity-evame ukubonakala ekubunjweni-ibangelwa ngokuyinhloko ukuvaleka kwegesi noma amasu okuthela angalungile, anganciphisa nakakhulu ubuqotho besakhiwo.
Ukuqhekeka Okushisayo Nokucindezela Kokusakaza
Ukuqhekeka okushisayo kungenye into ekhathazayo ebalulekile ekubumbeni. Lokhu kwenzeka lapho ukusakaza kusesemazingeni okushisa aphakeme kodwa sekuqalile ukuqina. Izingcindezi ezibangwa ngesikhathi sokupholisa zingadlula amandla aqinile wento, okuholela ekuqhekekeni. Ukulawula izinga lokupholisa kanye nokuqonda izici ezishisayo zezinto kungasiza ukunciphisa ubungozi bokuqhekeka okushisayo.
Ukuqhekeka Okubandayo kanye Nokuguqulwa
Ukuqhekeka okubandayo kwenzeka ngemva kokuba ukubunjwa sekuphole kumazinga okushisa asekamelweni futhi ngokuvamile kuba umphumela wokucindezeleka okusalayo. Lezi zingcindezi zingavela ngenxa yokupholisa okungalingani, okuholela ekufinyezeni okuhlukile kulo lonke uhlaka. Ukucindezeleka okunjalo kungase futhi kubangele ukuguquguquka, kube nomthelela esimweni sokugcina sokulingisa nokusebenziseka.
Ukuze kuncishiswe amathuba okuqhekeka okubandayo kanye nokuguqulwa, kubalulekile ukusebenzisa amasu okupholisa afanele kanye nezinqubo zokukhulula ukucindezeleka ngesikhathi nangemva kwenqubo yokuphonsa.
