Ntau pawg ntawm Steel Castings

Hlau castings xa mus rau cov castings uas ua los ntawm cov hlau alloy nrog rau ntau pua hom steel qib, uas yog tsim los ntawm ntau yam txheej txheem xws li xuab zeb casting, plhaub casting,peev casting, poob ua npuas ncauj casting thiab nqus casting. Cov hlau castings tuaj yeem siv rau ntau yam kev ua haujlwm sib txawv, thiab nws cov khoom siv kho tshuab zoo dua li lwm cov hlau casting. Thiab muaj ntau yam high-alloy steels haum rau lub hom phiaj tshwj xeeb.Hlau castingsyog qhov tshwj xeeb tshaj yog siv rau hauv cov xwm txheej no: cov khoom raug rau siab tensile kev nyuaj siab los yog dynamic load, tseem ceeb ntawm cov hlab ntsha castings, qhov chaw uas muaj loads loj nyob rau hauv qis los yog siab kub thiab lwm yam tseem ceeb Cheebtsam. Cov khoom uas ua haujlwm nyob rau hauv kev cuam tshuam thiab hnav yuav tsum tau cam khwb cia nrog siab manganese hlau.

Hlau castings raug cais raws li lawv cov tshuaj muaj pes tsawg leeg thiab muab faib ua cov cam khwb cia carbon steel qhov chaw, cam khwb cia hlau hlau qhov chaw thiabcam khwb cia stainless hlau qhov chaw. Raws li kev faib tawm ntawm cov yam ntxwv ntawm kev siv, steel castings tuaj yeem muab faib ua engineering thiab cov qauv cam khwb cia hlau (carbon alloy steel thiab alloy structural steel), cam khwb cia tshwj xeeb steel qhov chaw (corrosion-resistant stainless hlau, tshav kub-resistant steel, hnav-resistant steel, npib tsib xee-raws li alloy) thiab casting cuab yeej steel (tooj hlau, tuag steel). Hauv kev lag luam foundry, cov ntaub ntawv siv rau steel castings feem ntau subdivided raws li hauv qab no:

1) Cam khwb cia carbon steelcam khwb cia cov pa roj carbon tsawg, cam khwb cia nruab nrab carbon steel, cam khwb cia siab carbon steel (siab zog carbon steel)
2) Medium-alloy steel thiab low-alloy steel rau castingcam khwb cia manganese steel, cam khwb cia silico-manganese steel, cam khwb cia manganese-molybdenum steel, cam khwb cia manganese-molybdenum-vanadium tooj liab steel, cam khwb cia chromium steel, chromium-molybdenum cam khwb cia hlau, chromium-manganese-silicon cam khwb cia hlau, chromium-manganese Moly , chromium molybdenum vanadium cam khwb cia steel, chromium tooj liab cam khwb cia steel, molybdenum cam khwb cia hlau, chromium nickel molybdenum cam khwb cia hlau, thiab lwm yam. Hauv cov kab lus hauv qab no, peb yuav qhia txog cov khoom ntawm cov hlau alloy uas muaj feem xyuam thiab lub luag haujlwm ua los ntawm cov khoom siv tshuaj ib los ntawm ib qho.
3) Corrosion-resistant stainless hlau: ferritic stainless hlau, martensitic stainless hlau, austenitic stainless hlau thiabaustenitic-ferritic duplex stainless hlau.
4) Thaum tshav kub kub-resistant steel: high chromium steel, siab chromium nickel steel thiab siab nickel chromium hlau.
5) Wear-resistant cam khwb cia hlau: hnav-resistant manganese steel, hnav-resistant chromium hlau
6) Casting tshwj xeeb steel thiab kev hlau: low-temperature cast steel, foundry tool steel (tuag steel), siab cam khwb cia hlau, precision casting steel, centrifugal cam khwb cia steel yeeb nkab.

Txawm li cas los xij, kev poob siab, hnav tsis kam, fluidity thiab casting zog ntawm steel castings yog phem dua li ntawmgrey cam khwb cia hlauthiab ductile cam khwb cia hlau. Nyob rau tib lub sijhawm, tus nqi ntawm cov hlau castings yog siab dua li ntawm cov hlau castings. Tsis tas li ntawd, nyob rau hauv tib lub rigidity tej yam kev mob, tus txheeb ze qhov hnyav ntawm steel castings yog ob zaug ntawm aluminium alloy castings. Yog li ntawd, thaum xaiv cov cam khwb cia hlau, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xav txog kev siv tiag tiag thiab kev ua haujlwm ntawm tus nqi, thiab xaiv qhov tsim nyog tshaj plaws.
