1.Yuav ua li cas nws "harden"?
Kauj ruam 1: Ua ntej- txhim kho "Nails" (Composition Design)
Thaum lub sij hawm tsim cov hlau no, cov kws tshaj lij tswj hwm cov ntsiab lus ntawm cov pa roj carbon monoxide, tso cai rau ib feem me me ntawm cov pa roj carbon atom kom muaj nyob ua "dawb" (khoom-tshuaj atoms) ntawm cov hlau atoms. Cov no ua zoo li ua ntej- nruab "nails."
Kauj ruam 2: Stamping rau "Tsim cuab" (Machining)
Thaum cov ntawv hlau no raug ntaus rau hauv lub qhov rooj tsheb, qhov mob hnyav deformation ua rau muaj ntau yam tsis xws luag hauv cov hlau, hu ua "dislocations." Koj muaj peev xwm xav txog tej yam no dislocations li tshiab khawb "cuav" tos rau lub "nails" poob rau hauv.
Kauj ruam 3: Ci rau "Pin Dislocations" (Lub zog dhia)
Cov khoom stamped ces nkag mus rau hauv lub rhiav pleev xim rau ci (ntawm kwv yees li 170-}180℃). Lub tshav kub muab lub zog rau cov "dawb" carbon atoms, ua rau lawv sai sai thiab meej poob rau hauv "cuav" (dislocations), khov kho lawv zoo li rau tes. Qhov no yuav tsum muaj zog ntau dua los txuas ntxiv deforming cov khoom-macroscopically manifested raws li ib tug nce nyob rau hauv yield zog.
2.Vim li cas qhov no tseem ceeb heev?
Cov khoom zoo zoo: Lub zog pib qis txhais tau hais tias cov hlau ntws tau yooj yim thaum stamping cov duab nkhaus, tiv thaiv kev tawg thiab txo qhov hnav ntawm pwm.
Lub zog siab: Tom qab ci, lub zog nce los ntawm kwv yees li 40-80 MPa lossis ntau dua 30%, ua rau lub vaj huam sib luag tiav lawm muaj zog dua thiab dent-resistant (kuj hu ua "zoo dent resistance"). Tsis tas li ntawd, nws tso cai rau cov ntawv hlau nyias nyias thaum tuav lub zog, ua rau lub cev hnyav txo (cov ntaub ntawv tshawb fawb pom tias nws tuaj yeem pab txo qhov hnyav tag nrho los ntawm 7%).
3.Dab tsi yog qhov yuav tsum tau ua rau tus nqi ci ci (BH tus nqi)?
30-60 MPa yog qhov taw qhia tseem ceeb rau kev ntsuas qhov nce hauv lub zog tom qab ci. Tus nqi qis dhau yuav tsis muaj qhov cuam tshuam tseem ceeb, thaum tus nqi siab dhau lawm yuav ua rau cov khoom tawv tawv ntawm chav tsev kub.
4.Dab tsi yog qhov yuav tsum tau ua rau cov txheej txheem ci?
170℃× 20 feeb
Cov no yog cov txheej txheem tsis zoo rau kev simulating automotive painting kab.
5.Dab tsi yog qee cov cim lag luam?
CR180BH thiab HC220BD + Z yog cov khoom lag luam paub tab los ntawm cov hlau loj hauv tsev xws li Baosteel, Hebei Hlau thiab Hlau, thiab Tangshan Hlau thiab Hlau, thiab tau siv dav hauv cov qauv xws li Passat thiab Magotan.
