Maqondana nokupholisa kwe Amapayipi ensimbi engagqwali kwinqubo yokukhiqiza, izidingo zobuchwepheshe ezisetshenziswe lapha ziphezulu kakhulu. Isibonelo, uma ukulawulwa kwezinga lokushisa kungekuhle, okuphumela esizukulwaneni sokuxineka kwengcindezi ezingama-316 nokuxineka okuhlelekile, ipayipi lensimbi lingaqhekeka noma lizenze. Olandelayo, I-Hanao Tech (Seko Tech) izokwethula ngokuningiliziwe ulwazi lokukhiqiza amapayipi ensimbi engagqwali ngokupholisa:
Ngenxa yokwabiwa kabusha kwengxabano yangaphakathi ngesikhathi sokucubungula, ishubhu yensimbi engagqwali izolimala, futhi ukunemba okusebenzayo akunakuqinisekiswa. Ngaphezu kwalokho, ukuphatha izingxenye ezinkulu kuthambekele ekucindezelekeni okusele. Onke la mashubhu wokuhlobisa insimbi engagqwali kumele ayeke ukucindezela kwengcindezi ngemuva kwemishini enzima. Ukususwa kokuphazamiseka kwengcindezi yangaphakathi kuvame ukuhlobisa ishubhu lensimbi engenasici. Ku-500-550 ° C, phambilini bekusetshenziswa emazingeni okushisa asekamelweni imizuzu engama-50 kuye kwayi-100, amahora amathathu kuya kwayi-5 noma ngaphezulu (kuya ngenombolo yezinto ezifakiwe) ukuze ulondoloze ukungezwani kwangaphakathi isikhathi eside. Ibizwa ngokuthi ukuguga kwemvelo, kepha le ndlela inhlala isikhathi eside futhi imvamisa ayisetshenziswanga.
Lapho ishubhu lensimbi engenasici lipholile, ingaphezulu nezinye izingxenye ezincanyana zivame ukukhiqiza isakhiwo esimhlophe, esinzima, esimhlophe. Ngakho-ke, amashubhu wokuhlobisa insimbi engagqwali kufanele ancishiswe noma alinganise ukuqeda izinkinga zokuphonsa. Izinga lokushisa le-annelling noma elijwayelekile liphakathi kuka-850 no-950 ° C. Izinga lokushisa ligcinwa ngamahora angu-1-2, usimende uguqulwe ku-graphite ne-aupen (isigaba sokuqala sokwenziwa kwe-graphitization). -Kwethu Isithando somlilo esiqhubekayo esiqhubekayo singakusiza. Akudingi shehaing, ingafinyelela amazinga okushisa afanelekile phakathi kwemizuzwana eyi-10 ngemuva kokuqala.
Ngaphezu kwalokho, ixhumeke ohlelweni lwe-PLC, ungabona ngqo idatha yesikhathi sangempela, ukuqapha kwangempela kwesikhathi sokucindezela komoya, ukugeleza kwamanzi, izinga lokushisa elisebenzayo, ijubane. Ngesikhathi sokupholisa esilandelayo sesithando somlilo, isimende se-Secondary kanye ne-eutectoid Centekite izohlanganiswa nge-graphite (okungukuthi, isigaba sesibili se-braphitization). Ekugcineni, i-perlite ingezwa kwi-matrix ye-ferrite noma i-ferrite matrix ukunciphisa ubulukhuni namandla okuphoqeka. Ngaphezu kwalokho, inqubo yokufakazela i-850-950 ° C, kepha i-Conmentite kwinqubo yokuhambisa okujwayelekile, enganciphisa isikhathi sokuphola kobulukhuni be-tube yensimbi engenasici, nayo ingathola amandla athile nobulukhuni be-matrix ye-pearlite ndawonye.
