Kalafo ea Mocheso ea Pula Ho Thatafatsa Litšepe Tsa Stainless

Precipitation hardening (PH) martensitic stainless steel hangata e na le metsoako ea motsoako joalo ka koporo, lead, molybdenum, le titanium tse etsang mohato o thata. Lintho tsena tsa alloying li na le ho qhibiliha ho hoholo ho austenite, empa e nyane haholo ho martensite. Ka hona, kalafo ea mocheso ea pula e thatafatsang tšepe ea martensitic e lokela ho qala ka ho ba tharollo e tiileng ea ho qhibiliha ka botlalo mokhahlelo o thata o oeleng sebakeng sa as-cast. Ka mor'a moo, phekolo ea ho thatafatsa ea pula e etsoa ho fokotsa karolo ea bobeli ea ho thatafala, ka hona ho ntlafatsa matla a ho lahlela tšepe e sa hloekang le ho etsa hore e be le matla a ho thibela kutu. Ho phaella moo, phekolo ea tharollo e tla boela e ntlafatse ts'ebetso ea ho itšeha eapula e thatafatsang dibaka tsa tshepe.

Litšobotsi tsa Phekolo ea Mocheso ea Pula Ho Thatafatsa Litšepe Tsa Stainless:

• 1) Pele ho kalafo ea tharollo, e hloka ho futhumatsoa ho 650 ℃, ebe e futhumatsoa kapele ho mocheso o reriloeng esale pele. Li-castings li ka boela tsa kenngoa ka har'a libopi ka mocheso o phahameng.
• 2) Mocheso o tiileng oa tharollo ka kakaretso ke 1020-1060 ° C, 'me nako ea ho ts'oara e baloa ho ea ka keketseho e lekanang ea hora ea 1 bakeng sa keketseho e' ngoe le e 'ngoe ea 25 mm ea botenya ba lerako. Bakeng sa li-casting tse nang le libopeho tse rarahaneng, mocheso o tiileng oa tharollo o ka fokotsoa ho hoo e ka bang 930 ° C.
• 3) E le ho felisa ho se tšoane ha sebopeho sa dendritic le karohano ea likarolo ka li-castings tse kholo tsa tšepe, ho molemo ho etsa phekolo e phahameng ea mocheso oa homogenization pele ho tharollo e tiileng.
• 4) Mocheso oa phekolo ea botsofali o ka khethoa ka mokhoa o nepahetseng ho ea ka litlhoko tsa matla, boima le boima ba ho lahla.
• 5) E le ho ntlafatsa thepa ea mechine ea pula e thatafatsang lisebelisoa tsa tšepe tse sa hloekang, ka mor'a phekolo ea tharollo, moea o pholileng ka 700-810 ° C ka lihora tsa 2, ebe o pholile moea ka 620 ° C bakeng sa lihora tse 4. Sena se ka ntlafatsa haholo ts'ebetso ea ho itšeha ea li-castings.
