FAQ: Cov lus nug txog kev yuav khoom
Q1: Dab tsi yog qhov zoo tshaj plaws hardness rau tshuab ntxhua khaub ncaws kis tau tus mob?
A:55-58 HRC nto hardness nrog 30-35 HRC core toughness. Qhov kev sib npaug no muab qhov siab tshaj plaws hnav tsis kam thaum tiv thaiv kev tawg tawg thaum lub sij hawm tig-cycle shock loads.
Q2: Peb puas tuaj yeem siv 45 # hlau rau txhua daim ntawv thov iav?
A:45 # steel ua haujlwm rau lub teeb-rau- daim ntawv thov kev thauj khoom nruab nrab nrog lub voj voog suav qis dua 5,000. Rau siab - voj voog lossis siab - torque scenarios, 40Cr lossis 20CrMnTi xa cov kev ua tau zoo ntev dua - lub sijhawm ua haujlwm.
Q3: Dab tsi yog qhov kev hloov pauv siab tshaj plaws uas tuaj yeem ua tau?
A:Peb tuav ± 1.5 HRC variation nyob rau hauv ntau lawm batch. Kev lag luam tus qauv tso cai ± 2 HRC, tab sis kev tswj nruj dua ua kom cov iav ua haujlwm zoo ib yam.
Q4: Koj puas muab kev cai kho cua sov profiles?
A:Yog lawm. Peb muab cov quenching kub, tempering cycles, thiab rooj plaub - hardening depths phim rau koj cov kev thov tshwj xeeb.
Q5: Koj cov txheej txheem export ntim yog dab tsi?
A:Tag nrho cov khoom steel tau txais:
xeb- tiv thaiv roj txheej
Waterproof VCI wrapping
Ntoo pallet / crate ntim
Kev saib xyuas lub thawv ntim khoom
Cov ntaub ntawv thaij duab tag nrho
Q6: Koj puas tuaj yeem muab cov kev sim me me?
A:Yog lawm. Kev txiav txim mus sib hais pib los ntawm 100kg yog muaj rau cov khoom tsim nyog kuaj. Lub sijhawm ua haujlwm rau kev sim ua haujlwm yog 5-7 hnub ua haujlwm.
