Kodi Mpweya Woumitsa Zitsulo Zopanda Stainless N'chiyani?

Mpweya wowumitsa chitsulo chosapanga dzimbiri, chomwe chimatchedwa PH Chitsulo, chimatanthawuza mtundu wachitsulo chosapanga dzimbirizomwe zimawonjezera mitundu yosiyanasiyana ndi kuchuluka kwa zinthu zolimbitsa, ndipo mitundu yosiyanasiyana ndi kuchuluka kwa ma carbides, nitrides, carbonitrides ndi intermetallic mankhwala amawomberedwa kudzera munjira yowumitsa mvula. Mvula yowumitsa chitsulo chosapanga dzimbiri sikuti imakhala ndi mphamvu zambiri, komanso imakhala yolimba komanso kukana dzimbiri. Mvula yowumitsa zitsulo zosapanga dzimbiri zitha kuponyedwa kwathuInvestment casting foundrymalinga ndi zojambula zanu, zofunikira ndi momwe mungagwiritsire ntchito.

Malinga ndi zomwe zili muzinthu zazikulu za aloyi mu mpweya wowumitsa chitsulo chosapanga dzimbiri ndi zinthu zina zowumitsa, mpweya wowumitsa chitsulo chosapanga dzimbiri ukhoza kugawidwa m'magulu anayi motere:
(1)Kutentha kwa Martensitic Kuumitsa Chitsulo Chosapanga dzimbiri. Nthawi zambiri amakhala ndi kaboni wosakwana 0.1%. Limbikitsani powonjezera zinthu zowumitsa (mkuwa, aluminiyamu, titaniyamu ndi aluminiyamu, ndi zina zotero) kuti mupange kusowa kwa mphamvu. Zomwe zili mu chromium nthawi zambiri zimakhala zokwera kuposa 17%, ndipo faife woyenerera amawonjezedwa kuti asachite dzimbiri.
(2)Kuchuluka kwa Mvula Kulimbitsa Chitsulo Chosapanga dzimbiri, yokhala ndi mpweya wosapitirira 0.03% kuti iwonetsetse kulimba, kukana kwa dzimbiri, kuwotcherera komanso kugwira ntchito kwa matrix a martensite, ndi 12% chromium kuti zitsimikizire kukana kwa dzimbiri. Kuphatikiza apo, cobalt ya alloy element imawonjezedwa kuti ipititse patsogolo kutentha kwachitsulo.
(3)Semi-Austenitic Precipitation Kulimbitsa Zitsulo Zosapanga dzimbiri, ndiko kuti, mvula yanthawi yayitali yowumitsa chitsulo chosapanga dzimbiri, chokhala ndi chromium yosachepera 12%. Imakhala ndi mpweya wochepa, ndipo aluminiyumu ndiye chinthu chachikulu choumitsa mvula. Mvula yotere yowumitsa zitsulo zosapanga dzimbiri imakhala ndi ntchito yabwinoko kuposa mvula ya martensitic yomwe imawumitsa chitsulo chosapanga dzimbiri.
(4)Kutentha kwa Austenitic Kuumitsa Zitsulo Zosapanga dzimbirindi chitsulo chosapanga dzimbiri chokhazikika cha austenite m'maiko ozimitsidwa komanso okalamba. Zomwe zili ndi faifi tambala ndi manganese ndizokwera, ndipo zomwe zili mu chromium ndizokwera kuposa 13% kuti zitsimikizire kukana kwa dzimbiri komanso kukana kwa okosijeni. Nthawi yomweyo, mpweya wa austenitic woumitsa zitsulo zosapanga dzimbiri nthawi zambiri umawonjezera titaniyamu, aluminiyamu, vanadium kapena phosphorous ngati zinthu zowumitsa mvula, ndikuwonjezera pang'ono boron, vanadium, nayitrogeni ndi zinthu zina kuti mupeze zinthu zabwino kwambiri.

Mpweya wowumitsa zitsulo zosapanga dzimbiri zimagwiritsidwa ntchito kwambiri m'mafakitale apamwamba. Mwachitsanzo, mvula yomwe imaumitsa zitsulo zosapanga dzimbiri 17-4PH itha kugwiritsidwa ntchito popanga zinthu zosachepera 370 ° C zomwe zimafuna kukana dzimbiri, kukana kuvala, komanso mphamvu zambiri.
