I-ZG35Cr24Ni7SiN Centrifugal Cast Pipes: Izindleko{3}}Ukukhetha Okuphumelelayo Kwemboni Yamakhemikhali Ephakeme{4}}Izicelo Zezinga Lokushisa
Embonini yamakhemikhali, okokusebenza kusebenza ngaphansi kwezimo ezidinga kakhulu-izinga lokushisa eliphezulu, i-thermal cycling, i-oxidation, i-sulfidation, ne-corrosive atmosphere. Lezi zindawo ezinokhahlo zibeka izidingo eziqinile ekuthembekeni, ukuqina, nokusebenza kwezingxenye ezikwazi ukumelana nokushisa{2}}. Phakathi kwalezi zingxenye ezibalulekile, i-ZG35Cr24Ni7SiN centrifugal cast pipes igqama njengesixazululo esikhethwayo sokudlulisa{7}}igesi eshibilikayo enezinga lokushisa eliphezulu, i-process media, nezinto ezibolayo.
Eyaziwa kakhulu ngokuthi i-"Ni7N", i-ZG35Cr24Ni7SiN iyi-nickel-eyonga ukushisa kwe-austenitic{5}}insimbi eqinile engazweli elungiselelwe{6}}isevisi yezinga lokushisa eliphezulu. Uma kuqhathaniswa namabanga aphezulu e-nickel endabuko afana no-2520 (HK40 / 1.4841), iletha amandla alinganayo noma angcono ezinga lokushisa eliphezulu, ukumelana nokushaqeka okushisayo, nokusebenza kokugqwala ngenani eliphansi kakhulu. Eziningi zamakhemikhali okusebenza izinga lokushisa eliphezulu phakathi kuka-900℃no-1100 degree, i-ZG35Cr24Ni7SiN inikeza ibhalansi engcono kakhulu yokusebenza, ukwethembeka, nomnotho.
Lesi sihloko sihlinzeka ngombono obanzi wamazinga wezinto ezibonakalayo we-ZG35Cr24Ni7SiN, ukwakheka kwamakhemikhali, izakhiwo ezibalulekile, izinzuzo ze-centrifugal Casting, izinhlelo zokusebenza ezijwayelekile, nokuqhathaniswa kwebanga lamazwe ngamazwe, ukusiza onjiniyela bamakhemikhali, amaqembu okuthenga, nabaphathi bezitshalo ukwenza izinqumo zokukhetha benolwazi.

1. Amazinga Wezinto & Nokwakheka Kwamakhemikhali

I-ZG35Cr24Ni7SiN iyi-chromium ephezulu, i-low-nickel austenitic ekwazi ukumelana nokushisa insimbi eyakhelwe ukukhiqizwa kwamapayipi asakazwa amaphakathi. Ukwakheka kwamakhemikhali ayo kubhalansiswa ngokunembile ukumelana ne-oxidation ephezulu yezinga lokushisa, ukumelana ne-sulfidation, nokuzinza kwesakhiwo, kuyilapho kunciphisa okuqukethwe kwe-nickel ukuze kusetshenziswe kahle izindleko.
