Ngemuva kokukhulisa, ukuguqula isimo, ukucima, ukuguquguquka nokuguqulwa komhlaba okuvuthayo, okuthethelelwa kungakhiqiza ukuhlanekekekelwa kwekwelashwa okushisayo.

Imbangela yokuhlanekezela ukucindezelwa kwangaphakathi kokusolwa ngesikhathi sokwelashwa okushisa, okungukuthi, ukucindezela kwangaphakathi kwalokhu okusolwa ngemuva kokwelashwa okushisa kuhlala ngenxa yokwelashwa okushisa kuhlala ngenxa yokwelashwa okuphakathi nangaphandle nangaphandle kwenguquko yesakhiwo.

Lapho le ngcindezi idlula iphuzu lesivuno lensimbi ngesikhathi esithile ngesikhathi sokwelashwa okushisa, kuzodala ukuhlanekezela kwalokhu kwakha.

Ukuxineka kwangaphakathi okukhiqizwa kwinqubo yokwelashwa okushisa kufaka phakathi ukucindezelwa okushisayo kanye nokushintsha kwesigaba.

1. Ukucindezela okushisayo
Lapho lokhu kufungiswa kufudunyezwa futhi kupholile, kuhambisana nesikhathi sokwandisa okushisayo kanye nokukhishwa okubandayo. Lapho ingaphezulu kanye nomnyombo kwalokhu kuthethelela kufudunyezwa noma kupholile ngejubane elihlukile, okuholela umehluko wokushisa, ukunwebeka noma ukukhishwa kwevolumu nakho kuhlukile kwale ndawo kanye nomnyombo. Ukucindezela kwangaphakathi okubangelwa izinguquko ezihlukile zevolumu ngenxa yomehluko wokushisa ibizwa ngokuthi ukucindezelwa okushisayo.
Esezinhlelweni zokwelashwa okushisa, ukucindezelwa okushisayo kwalokhu kwaziswa kubonakaliswa ikakhulukazi njengoba: Lapho lokhu kufunwa kufudumele, izinga lokushisa elingaphezulu likhuphuka ngokushesha kunomgogodla, izinga lokushisa eliyinhloko liphezulu futhi alikhuli , ngalesi sikhathi ukucindezelwa kwengcindezelo ye-warce compression kanye nokucindezelwa kwengxabano.
Ngemuva kwe-diathermy, izinga lokushisa eliyisisekelo kukhuphuka futhi kwanda ukwanda. Ngalesi sikhathi, ukucebisisa kukhombisa ukwanda kwevolumu.
I-WorkiePepe Cooling, indawo epholile epholile ngokushesha kunomgogodla, ukushisa okuphezulu, izinga lokushisa eliphakemeyo ukuvikela ukucindezelwa okuthile, lapho kupholile ukucindezela okuthile, Futhi ukupholisa okuyisisekelo okwenzekayo ngenxa yokuqhubeka kwengxenye, ingaphezulu lengcindezi elicindezelayo, kuyilapho inhliziyo yokuxineka, ingcindezi esekupheleni kokupholisa isekhona ngaphakathi kokwenza okusabekayo.

2. Isigaba Shintsha Ukucindezela

Esezinhlelweni zokwelashwa okushisa, isisindo kanye nevolumu yokwenziwa kwevolumu kumele kushintshe ngoba isisindo kanye nevolumu yezakhiwo ezahlukahlukene zihlukile.
Ngenxa yomehluko wokushisa phakathi kobuso nomnyombo wezomnotho, ukuguqulwa kwezicubu phakathi kobuso kanye nomgogodla akusona ngesikhathi, ngakho-ke ukucindezela kwangaphakathi kuzokwenziwa lapho kuvela ukucindezela kwevolumu kanye noshintsho lwevolumu.
Lolu hlobo lokuxinzeka kwangaphakathi olubangelwa umehluko wezinguquko zezicubu lubizwa ngokuthi yiSigaba Shintsha Ukuxineka.

Amavolumu amaningi ezakhiwo ezisisekelo ensimbi andiswe ngokulandelana kwe-auntenitic, Pearlite, Soustenitic, Toostite, Hypobainite, osolwa kanye ne-martensite kanye neMferensite.
Ukwenza isibonelo, lapho lokhu kucishwa kuqedwe futhi kusolwa ngokushesha, ungqimba olungaphezulu luguqulwa kusuka ku-Autenite kuya ku-Martensite futhi ivolumu iyandiswa, kepha inhliziyo isezingeni eliphezulu, ivikela ukwanda kwesendlalelo se-autentite. Ngenxa yalokho, inhliziyo yalokho kwaziswa ifakwa ekucindezelweni okuthe xaxa, kuyilapho ungqimba olungaphezulu lucindezelwa.
Lapho iqhubeka nokupholisa, izinga lokushisa elingaphezulu liyehla futhi alisakhuli, kepha ivolumu yenhliziyo iyaqhubeka nokugxuma njengoba ishintshana ebusweni, ngakho-ke inhliziyo itholwa yingcindezi ecindezelekile, kanye ingaphezulu libhekwe ekucindezelweni okuthe xaxa.
Ngemuva kokupholisa ifindo, le ngcindezi izohlala ngaphakathi kwababiyo futhi ibe yingcindezi eyinsalela.

Ngakho-ke, ngesikhathi senqubo yokucisha nokupholisa, ukucindezela okushisayo kanye nokucindezela kokuguquguquka kwesigaba kuphambene, futhi lezi zingcindezi ezimbili ezisele ekuthethelweni nazo zibhekene.
Ukuxineka okuhlanganisiwe kokucindezelwa kwengcindezi eshisayo kanye nokuxineka kwesigaba kubizwa ukuqeda ukucindezela kwangaphakathi.
Lapho ukucindezelwa kwangaphakathi okusele ekubumbeni kudlula iphuzu lesivuno lensimbi, umsebenzi wokwakha uzokhiqiza ipulasitiki, okuphumela ekuhlanekezinisweni.
