Kuzindikira zolakwika za mbale yachitsulo ya ASTM-SA516Gr60Z35:
1. Muyezo wa SA516Gr60: Miyezo ya American ASTM, ASME
2. SA516Gr60 ndi ya chotengera cha mpweya wochepa kutentha chomwe chili ndi mbale yachitsulo cha kaboni
3. Kapangidwe ka mankhwala a SA516Gr60
C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45.
4. Kapangidwe ka makina a SA516Gr60
SA516Gr60 mphamvu yokoka ya mapaundi 70,000/sikweya mainchesi, chinthu chachikulu chomwe chili mkati mwake ndi C Mn Si ps control chomwe chimatsimikizira magwiridwe antchito ake. Zinthu zina zochepa. Mafotokozedwe Okhazikika a Asme a mbale zachitsulo cha kaboni za zotengera zapakati komanso zotentha kwambiri.
5. Momwe SA516Gr60 imaperekera katundu
Mbale yachitsulo ya SA516Gr60 nthawi zambiri imaperekedwa mu mkhalidwe wozungulira, mbale yachitsulo imathanso kusinthidwa kukhala yabwinobwino kapena kuchepetsa kupsinjika, kapena kusinthasintha komanso kupumula kupsinjika.
Makulidwe a mbale yachitsulo ya SA516Gr60 >40mm ayenera kusinthidwa kukhala abwinobwino.
Pokhapokha ngati wofuna kufunikira wanena mwanjira ina, makulidwe a mbale yachitsulo ≤1.5in, (40mm), ngati pali zofunikira pakulimba, ayenera kusinthidwa kukhala abwinobwino.
6. SA516Gr60 imagwiritsidwa ntchito popanga chidebe chowotcherera cha coil cha single-layer, chidebe chowotcherera cha coil cha multi-layer hot sleeve, chidebe chodzola cha multi-layer ndi mitundu ina iwiri kapena itatu ya zidebe ndi zidebe zotentha zotsika kutentha. Amagwiritsidwa ntchito kwambiri mu mafuta, makampani opanga mankhwala, malo opangira magetsi, boiler ndi ntchito zina, amagwiritsidwa ntchito popanga ma reactor, zosinthira kutentha, zolekanitsa, matanki ozungulira, matanki amafuta ndi gasi, matanki a gasi osungunuka, ng'oma ya boiler, masilinda a nthunzi ya petroleum osungunuka, mapaipi amadzi othamanga kwambiri a siteshoni ya hydropower, turbine volute ndi zida zina ndi zida zina.
7. Pamene austenite yazizidwa pang'onopang'ono (yofanana ndi kuzizira kwa ng'anjo, monga momwe zasonyezedwera pa Chithunzi 2 V1), zinthu zosinthira zimakhala pafupi ndi kapangidwe kake, komwe ndi pearlite ndi ferrite. Pamene kuzizira kukuwonjezeka, ndiko kuti, pamene V3>V2>V1 ikuwonjezeka, kuzizira kwa austenite kumawonjezeka pang'onopang'ono, ndipo kuchuluka kwa ferrite yozimiririka kumachepa, pomwe kuchuluka kwa pearlite kumawonjezeka pang'onopang'ono, ndipo kapangidwe kake kamakhala kosalala. Panthawiyi, ferrite yochepa yozimiririka imagawidwa kwambiri pamalire a tirigu.
8. Chifukwa chake, kapangidwe ka v1 ndi ferrite+pearlite; Kapangidwe ka v2 ndi ferrite+sorbite; Kapangidwe kakang'ono ka v3 ndi ferrite+troostite.
9. Pamene liwiro lozizira ndi v4, kuchuluka kochepa kwa ferrite ndi troostite (nthawi zina kuchuluka kochepa kwa bainite kumatha kuoneka) kumapangika, ndipo austenite imasinthidwa kwambiri kukhala martensite ndi troostite; Pamene liwiro lozizira v5 limaposa liwiro lozizira lofunikira, chitsulocho chimasinthidwa kwathunthu kukhala martensite.
10. Kusintha kwa chitsulo cha hypereutectoid kumafanana ndi kwa chitsulo cha hypoeutectoid, kusiyana kwake ndikuti ferrite imayamba kugwedezeka mu chomaliza ndipo cementite imayamba kugwedezeka mu choyamba.
