Forged npas rau kub kub pob zeb ua ntxhua ua thiab cov yam ntxwv ntawm kev siv

Forged npas rau kub ore mine pob zeb ua nrog cov zoo nto zoo, zoo cuam tshuam, muaj zog toughness, zoo coj ua hauj, thiab tsis yooj yim tawg thiab puag ncig. Peb siv txoj kev xa khoom thiab cov thwj cim kom sov lub cua kom txog thaum ntsuas kub txog 1050 ° C (± 50 ° C), siv lub tshuab forging rau kev siv lub tshuab ua kom tsis muaj teeb meem rau nws kom tau txais tej yam khoom zoo, cov duab thiab loj. Kev ua ntawm kev zam txim.

Forged npas yog siv rau cov ntxhuav kub ntxhov. Forging tau tshem tawm tsis xws luag xws li-nrum looseness tshwm sim los ntawm cov hlau hauv cov txheej txheem smelting, optimize microstructure, thiab tib lub sij hawm, cov khoom siv dag zog ntawm cov forgings feem ntau zoo dua cov ntaub ntawv tib yam vim cov preservation ntawm cov hlau tiav kab. casting. Cov hlau steel hlau yuav tsum tau hnav cov khoom siv tawv hnyav rau feem ntau. Peb siv hlau ua los ntawm lub teb chaws loj-loj steel mills. Nws kuj yog ib hom khoom. Qhov zoo tsim nyob rau hauv txawv steel mills kuj txawv, thiab qhov kev zam ntawm kev ua zoo yog qhov zoo los sis qhov phem. 80% nyob ntawm qhov zoo ntawm cov khoom siv, xws li kev siv cov manganese hlau, ua haujlwm zoo, muaj zog toughness, zoo coj ua hauj, tsis yooj yim rau kev tawg. Forged steel npas raug xaiv los ntawm cov neeg siv vim lawv tsis tshua muaj nqi, kev lag luam thiab kev ua haujlwm.

Cov yam ntxwv ntawm forged npas siv hauv cov ntxhua ua pob zeb kub

1. Tus nqi tawg yog tsawg dua 0.5%.

2. Toughness toughness: feem cuam tshee muaj ntau tshaj 18J / cm2, thiab 8m pob xeem test ntau tshaj 20,000 zaug.

3, zuag qhia tag nrho yog qhov siab: qhov nyuaj hardness ntawm 58-65HRC, ntim hardness ntawm 56-63HRC, thiab qhov gravity gradient nruab nrab.

4, tsis muaj qhov deformation: lub pob zeb yog ib txwm tsis deformed, tsis ploj.

5, lub koom haum yog kev cog lus, kev siv nyiaj, thiab kev txuag nyiaj tseem ceeb.
