Ngaphezu kokusetshenziselwa ukukhipha uwoyela, ukuvela kwegobolondo likawoyela kungasetshenziswa futhi njengepayipi lokuthutha impahla eluhlaza. Ukuze kuthuthukiswe ikhwalithi yesikhwama sikawoyela, sonke isixhumanisi senqubo yokukhiqiza sibaluleke kakhulu, ikakhulukazi ukulawulwa kwezinga lokushisa phakathi nenkathi, okufanele kulandelwe ngokuqinile. Ubungcweti bemithetho. Imvamisa, i-petroleum casing isebenzisa indlela yokucisha izinga lokushisa elingaphansi esikhundleni sendlela evamile yokucisha, ngoba indlela evamile yokucisha izoshiya inani elikhulu lokucindezeleka okusala ngaphakathi kwendawo yokusebenza, ngaleyo ndlela yandise ukushwabana nokwenza ukucubungula okulandelayo kungabi lula. Ukucisha izinga lokushisa elingaphansi ukuvimbela ukonakala okweqile kwegobolondo likawoyela ukuthi lingathinti inqubo elandelayo. Indlela yokusebenza eyinhloko iwukuqala ngokukhetha izinga lokushisa lokushisa lokucisha izinga lokushisa elingaphansi, ngokuvamile eliphakathi kuka-740-810°C, futhi isikhathi sokushisisa ngokuvamile siba yimizuzu eyi-15. Ngemuva kokuqhakaza, ukuthambisa kwenziwa. Isikhathi sokushisa sokushisisa imizuzu engamashumi amahlanu, futhi izinga lokushisa kufanele libe ngu-630°C. Yiqiniso, uhlobo ngalunye lwensimbi lunokushisa kwalo kanye nesikhathi ngesikhathi sokwelashwa kokushisa. Uma nje ingathuthukisa ukusebenza kwe-workpiece, khona-ke ukwelashwa kokushisa Inhloso ifinyelelwa.

Ukwelashwa kokushisa kuyinqubo ebaluleke kakhulu ekucutshungulweni kwe-petroleum casing. Ukuthi ukusebenza kanye nekhwalithi yomkhiqizo oqediwe kungahlangabezana nezindinganiso ikakhulukazi kuncike emiphumeleni yokwelashwa kokushisa. Ngakho-ke, umkhiqizi ngamunye unezidingo eziqinile kakhulu zenqubo yokwelashwa kokushisa futhi angalokothi angakunaki. Kwesinye isikhathi ukucisha izinga lokushisa eliphansi kungasetshenziswa ukucisha. Ukucisha izinga lokushisa eliphansi kungasusa ngempumelelo ukucindezeleka okusele kwegobolondo likawoyela. Ayinciphisi nje kuphela izinga lokuwohloka kwe-workpiece ngemva kokucisha kodwa futhi icubungula i-casing kawoyela ibe izinto ezingavuthiwe ezifaneleka kakhudlwana izinqubo zakamuva. Ngakho-ke, impumelelo yamanje ye-oyela casing ayinakuhlukaniswa nokwelashwa kokushisa. Njengoba inqubo yokwelapha ukushisa yethuliwe, kungakhathaliseki ukuthi ukuqina komthelela, ukusebenza kokulwa nokucekela phansi, noma amandla aqinile wegobolondo likawoyela, kube nokuthuthuka okukhulu. ngcono.
