35CrMo ingxubevange yentsimbi umbhobho
Inkcazelo emfutshane:
Iinkcukacha ngemveliso:
Ububanzi bangaphandle bombhobho wensimbi 20-426
Umbhobho wentsimbi ubukhulu bodonga lwe-20-426
Intshayelelo yemveliso:
Ngokomzekelo, i-40Cr.(Umxholo weCarbon we-35CrMo ingxubevange yombhobho wentsimbi yi-0.32 ~ 0.40, i-silicon 0.17~0.37, i-manganese 0.40 ~ 0.70, i-molybdenum 0.15 ~ 0.25, i-chromium 0.80 ~ 1.10)
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.
Ityhubhu ye-alloy kunye netyhubhu engenamthungo zombini zinobudlelwane kunye nomahluko, azinakubhideka.
Umbhobho we-alloy yipayipi yensimbi ngokuhambelana nezinto zokuvelisa (oko kukuthi, izinto eziphathekayo) ukuchaza, njengoko igama libonisa ukuba lenziwe ngombhobho we-alloy;Kunye umbhobho ingenamthungo yintsimbi umbhobho ngokungqinelana nenkqubo yemveliso (ingenamthungo) ukuchaza, eyahlukileyo umbhobho ingenamthungo yi welded umbhobho, kubandakanywa ngqo umthungo welding umbhobho kunye umbhobho spiral.
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
