Zvikamu zvakasiyana zveSimbi Castings

Steel castings inoreva ma castings anogadzirwa nealloy simbi inosanganisira mazana emhando dzesimbi mamakisi, ayo anogadzirwa neakawanda akasiyana maitiro ekukanda sejecha kukanda, shell casting,Investment casting, yakarasika furo nekukanda vacuum. Simbi castings inogona kushandiswa muakasiyana akasiyana ekushanda mamiriro, uye yakazara ma mechanical zvivakwa zviri nani pane chero imwe alloy casting. Uye kune zvakasiyana-siyana zve-high-alloy steels zvakakodzera zvinangwa zvakakosha.Steel castingsanoshandiswa zvakanyanya mumamiriro ezvinhu aya: zvikamu zviri pasi pekunetseka kwakanyanya kana kusimba kwesimba, zvakakosha kumanikidza ngarava castings, zvikamu zviri pasi pemitoro yakakura pane yakaderera kana yakakwirira tembiricha uye zvimwe zvakakosha zvikamu. Zvikamu zvinoshanda pasi pesimba uye kupfeka mamiriro anofanirwa kukandwa nesimbi yakakwira manganese.

Steel castings yakakamurwa zvinoenderana nemakemikari ayo uye akakamurwa kuita cast carbon simbi zvikamu, cast alloy simbi zvikamu uye.zvikamu zvesimbi isina tsvina. Zvinoenderana nechikamu chemaitiro ekushandisa, simbi yekukanda inogona kupatsanurwa kuita engineering uye zvimiro zvakakandwa simbi (carbon alloy simbi uye alloy structural simbi), akakanda akakosha simbi simbi (corrosion-resistainless simbi, kupisa-resistant simbi, kupfeka-inodzivirira simbi, nickel-based alloy) uye simbi yekukandira (chishandiso simbi, die simbi). Muindasitiri yekuvamba, zvinhu zvinoshandiswa pakugadzira simbi zvinowanzo kupatsanurwa sezvizvi:

1) Kanda kabhoni simbi: kukanda yakaderera kabhoni simbi, kukanda svikiro kabhoni simbi, kukanda yakakwira kabhoni simbi (yakakwirira simba kabhoni simbi)
2) Medium-alloy simbi uye yakaderera-alloy simbi yekukanda: cast manganese simbi, cast silico-manganese simbi, cast manganese-molybdenum simbi, cast manganese-molybdenum-vanadium copper simbi, cast chromium simbi, chromium-molybdenum simbi yakakandwa, chromium-manganese-silicon cast simbi, chromium-manganese cast iron Molybdenum , chromium molybdenum vanadium cast simbi, chromium copper cast steel, molybdenum cast steel, chromium nickel molybdenum cast steel, etc. Zvinhu zvakasiyana-siyana zvemakemikari zvinogona kuita basa rakasiyana pakuvandudza kushanda kunoenderana. Muzvinyorwa zvinotevera, isu tichazivisa maitiro eakabatana alloy simbi uye mabasa anotambwa nemakemikari zvinhu chimwe nechimwe.
3) Corrosion-resistant simbi isina tsvina: ferritic Stainless simbi, martensitic Stainless simbi, austenitic Stainless simbi uyeaustenitic-ferritic duplex simbi isina tsvina.
4) Simbi inodzivirira kupisa: yakakwirira chromium simbi, yakakwirira chromium nickel simbi uye yakakwirira nickel chromium simbi.
5) Pfeka-resistant cast simbi: kupfeka-inodzivirira manganese simbi, kupfeka-inodzivirira chromium simbi
6) Kukanda simbi yakakosha uye simbi yehunyanzvi: yakaderera-tembiricha yakakanda simbi, foundry mudziyo simbi (kufa simbi), pressure cast simbi, chaiyo kukanda simbi, centrifugal cast cast simbi pombi.

Nekudaro, iyo yekukatyamadza kunyura, kupfeka kuramba, fluidity uye kukanda zvimiro zvesimbi castings zvakaipisisa kupfuura izvo zve.grey cast ironuye ductile cast iron. Panguva imwecheteyo, mari yekukanda simbi yakakwirira kudarika yesimbi. Mukuwedzera, pasi pemamiriro akafanana ekuoma, huremu hwehuremu hwesimbi yakakandwa kaviri iyo yealuminium alloy castings. Naizvozvo, pakusarudza simbi yakakandwa, zvinodikanwa kunyatso funga nezve chaiyo yekushandisa uye mutengo kuita, uye kuita sarudzo inonzwisisika.
