Forged qhov chaw (siv hauv tsheb, aerospace, thiab lwm yam) xav tau kev tswj xyuas nruj ntawm txhua kauj ruam -txhua qhov kev sib tsoo ua rau lub zog lossis qhov raug. Hauv qab no yog cov chaw kuaj xyuas tseem ceeb los ntawm cov khoom siv raw mus rau kev xa khoom ..
Cov khoom siv raw tswj tau ua ntej. Cov neeg muab khoom yuav tsum muab EN 10204 3.1 daim ntawv pov thawj; hauv - pab pawg hauv tsev ua spectral tsom xam (kom ntes cov hlau tsis sib haum) thiab kev ntsuas tensile (kom paub meej tias cov khoom muaj zog / ductility). Off-spec batch raug tso tseg tam sim ntawd
Nyob rau hauv forging, raw billets yog rhuab mus rau 1100-1250℃(rau carbon steel) optimize plasticity. Cov neeg khiav dej num ua qhov kev kuaj pom (rau cov kab nrib pleb / quav) thiab ntsuas qhov sib nqus (MT) rau qhov tsis zoo. Tom qab-forging kev kho cua sov (quenching/tempering) siv cov thermocouples los xyuas kom meej hardness zoo ib yam.
Kev ua tiav kawg pib nrog kev sib koom tes ntsuas tshuab (CMMs) kom paub tseeb ± 0.02mm kam rau ua. Yuav tsum tsis yog-kev kuaj kev puas tsuaj (NDT) raws li nram no: kuaj ultrasonic (UT) rau cov voids sab hauv, dye penetrant testing (PT) rau saum npoo tawg. Kev ntsuam xyuas zaum kawg (kev kuaj load / qaug zog) ua kom ASTM A325 ua raws.
Traceability cia siab rau cov ntaub ntawv digital (batch logs, checklists) kom taug qab qhov tsis xws luag rau cov kauj ruam tshwj xeeb. Qhov kawg no -rau- kawg tswj txiav cov khoom pov tseg thiab ua kom cov khoom ua haujlwm hauv siab - cov xwm txheej tshwm sim.
