30CrMo ingxubevange yentsimbi umbhobho

Inkcazelo emfutshane:

Iinkcukacha ngemveliso:

Ububanzi bangaphandle bombhobho wensimbi 20-426

Umbhobho wentsimbi ubukhulu bodonga lwe-20-426

Intshayelelo yemveliso:

① Amanani amabini ekuqaleni kwenombolo yentsimbi abonisa umxholo wekhabhoni wentsimbi, kunye nomyinge wekhabhoni wamawaka ambalwa, njenge 40Cr, 30CrMo ingxubevange yombhobho wentsimbi.

② Izinto eziphambili zokudibanisa kwintsimbi, ngaphandle kwezinye izinto ezincinci, zibonakaliswa ngokubanzi ngeepesenti ezininzi.Xa umxholo we-alloy ophakathi ungaphantsi kwe-1.5%, kuphela isimboli se-element siphawulwe ngokubanzi kwinombolo yentsimbi, kodwa kungekhona umxholo.Nangona kunjalo, kwiimeko ezikhethekileyo, kulula ukubhidanisa, inombolo "1" inokumakishwa emva kwesimboli sento, njengenombolo yensimbi "12CrMoV" kunye ne "12Cr1MoV", umxholo wechromium yangaphambili ngu-0.4-0.6%, kwaye le yokugqibela yi 0.9-1.2%.Yonke enye into iyafana.Xa i-avareji yesiqulatho se-alloying element ≥1.5%, ≥2.5%, ≥3.5%…… “, isimboli ye-elementi kufuneka imakishwe emva komxholo, ingabonakaliswa njengo-2, 3, 4……… njl. Umzekelo, 18Cr2Ni4WA.

③ Izinto ze-alloy ezifana ne-vanadium V, i-titanium Ti, i-aluminiyam AL, i-boron B kunye nomhlaba onqabileyo we-RE kwintsimbi zizinto ze-microalloying elements.Nangona umxholo uphantsi kakhulu, kufuneka zisaphawulwe kwinombolo yentsimbi.Ngokomzekelo, kwintsimbi ye-20MnVB.I-Vanadium yi-0.07-0.12% kunye ne-boron yi-0.001-0.005%.

④ "A" kufuneka yongezwe ekupheleni kwenombolo yentsimbi yezinga eliphezulu lensimbi ukuze lihluke kwintsimbi yezinga eliphezulu.

⑤ Injongo ekhethekileyo ye-alloy structural iron, i-steel number prefix (okanye isimamva) imele injongo yesimboli yentsimbi.Umzekelo, intsimbi ye-30CrMnSi esetyenziselwa ngokukodwa izikrufu ze-riveting ichazwa njenge-ML30CrMnSi.

Itekhnoloji yokuvelisa:

1. Ukuqengqeleka okushushu (umbhobho wentsimbi ongenamthungo) : ityhubhu engqukuva ingenanto → ukufudumeza → ukugqobhoza → ukuqengqeleka kwediagonal ezintathu eziphezulu, ukuqengqeleka okuqhubekayo okanye ukukhutshwa → ukuhluba → ukulinganisa (okanye ukunciphisa) → ukupholisa → ukulungisa → uvavanyo lwe-hydrostatic (okanye ukuhlolwa) → ukumakisha → ugcino

2. Umbhobho wentsimbi obandayo (uqengqelekiyo) ongenamthungo: ityhubhu engqukuva ingenanto → ukufudumeza → ukugqobhoza → isihloko → ukuqhola → ukuchola → ukufakwa kwe-oyile (iplate yobhedu) → umzobo obandayo ohamba ngeendlela ezininzi (ukuqengqeleka okubandayo) → ityhubhu engenanto → unyango lobushushu → ukulungisa → uvavanyo lwe-hydrostatic (ukuhlolwa) → ukumakisha → ukugcinwa
