Iindaba-Intshayelelo kwiLifting Chain of Grades: G80, G100 & G120

Ukuphakamisa amatyathanga kunye nezilingingamacandelo abalulekileyo kuwo wonke ulwakhiwo, ukuvelisa, imigodi, kunye namashishini angaphesheya. Ukusebenza kwabo kuxhomekeke kwisayensi yezinto kunye nobunjineli obuchanekileyo. Amabanga amakhonkco e-G80, G100, kunye ne-G120 amele iindidi zamandla aqhubekayo ngokuqhubekayo, achazwa ngamandla awo asezantsi e-tensile (kwiMPa) aphindaphindwe nge-10:

- G80: 800 MPa ubuncinci amandla okuqina

- G100: 1,000 MPa ubuncinci bokuqina kwamandla

- G120: 1,200 MPa ubuncinci amandla okuqina

La mabanga ahambelana nemigangatho yamazwe ngamazwe (umz., ASME B30.9, ISO 1834, DIN EN818-2) kwaye ahlolwa ngokungqongqo kwaye avavanywe ukuqinisekisa ukuthembeka phantsi kwemithwalo eguqukayo, amaqondo obushushu agqithisileyo, kunye nemekobume eyonakalisayo.

1. IiMathiriyeli kunye neMetallurgy: iSayensi eNgemva kwamaTyayini aPhakamisayo amaBanga

Iimpawu zomatshini zala matyathanga okuphakamisa zivela ekukhethweni okuchanekileyo kwe-alloy kunye nonyango lokushisa.

IBanga	Izinto ezisisiseko	Unyango lobushushu	Izinto ezingundoqo zokudibanisa	Iimpawu zeMicrostructural
G80	Medium-carbon steel	Ukucima kunye nokunciphisa	C (0.25-0.35%), uMn	I-martensite epholileyo
G100	Amandla aphezulu asezantsi-alloy (HSLA) intsimbi	Ukucima okulawulwayo	Cr, Mo, V	I-fine-grained bainite/martensite
G120	Advanced HSLA steel	Ukuthambisa ngokuchanekileyo	Cr, Ni, Mo, micro-alloyed Nb/V	Ukusasazwa kwe-carbide ecocekileyo kakhulu

Kutheni kwaye zibaluleke kangakanani ezi mathiriyeli:

- Ukwandiswa kwamandla: Izinto ze-alloying (Cr, Mo, V) zenza i-carbides ezithintela ukuhamba kwe-dislocation, ukwandisa amandla okuvelisa ngaphandle kokuncama i-ductility.

-Ukudinwa Ukumelana: Ii-microstructures ezicolekileyo kwi-G100/G120 zithintela ukuqaliswa kokuqhekeka. I-G120's tempered martensite inika ubomi obuphezulu bokudinwa (>100,000 imijikelo kwi-30% WLL).

- Nxiba ukuxhathisa: Ukuqina komphezulu (umzekelo, ukuqina kwe-induction) kwi-G120 kunciphisa i-abrasion kwizicelo zokukhuhla okuphezulu njenge-draglines mining.

IiProtocol zeWelding ye-Chain Integrity

•Pre-Weld Prep:

o Coca iindawo ezidibeneyo ukususa iioksidi/izingcolisi.

o Ukutshisa kwangaphambili ukuya kuma-200°C (G100/G120) ukuthintela ukuqhekeka kwehydrogen.

•Iindlela zokuwelda:

o I-Laser Welding: Kwimixokelelwane ye-G120 (umzekelo, i-Al-Mg-Si ialloys), i-welding emacala amabini idala iindawo ezidityanisiweyo kunye ne-H-shaped HAZ yokusabalalisa uxinzelelo olufanayo.

o I-TIG ye-Hot Wire: Kwi-boiler steel chains (umzekelo, i-10Cr9Mo1VNb), i-multi-pass welding inciphisa ukugqwesa.

•Ingcebiso ebalulekileyo:Ziphephe iziphene zejometri kwi-HAZ – iindawo ezinkulu zokuqalisa ii-crack ezingaphantsi kwe-150°C.

IiParameters zoNyango lwe-Post-Weld Heat (PWHT).

IBanga	Ubushushu be-PWHT	Bamba Ixesha	Utshintsho lweMicrostructural	Ukuphuculwa kwePropati
G80	550-600°C	2-3 iiyure	I-martensite epholileyo	Ukunciphisa uxinzelelo, + 10% impembelelo yokuqina
G100	740-760°C	2-4 iiyure	Ukusasazwa kakuhle kwe-carbide	I-15% ↑ amandla okudinwa, i-HAZ efanayo
G120	760-780°C	1-2 iiyure	Ithintela i-M₂₃C₆ ukurhabaxa	Ikhusela ukulahleka kwamandla kwiqondo lokushisa eliphezulu

Isilumkiso:Ukugqithisa i-790 ° C kubangela i-carbide i-coarsening → amandla / ilahleko ye-ductility.

2. UkuPhakanyiswa kokuSebenza kwamaTyayini kwiiMeko eziBabekileyo

Iimeko ezahlukeneyo zifuna izisombululo zemathiriyeli ezilungiselelweyo.

Ukunyamezela ubushushu:

-G80:Ukusebenza okuzinzileyo ukuya kuma-200 ° C; kunye nokulahleka kwamandla ngokukhawuleza ngaphezu kwe-400 ° C ngenxa yokuguqulwa kobushushu.

-G100/G120:Amatyathanga Gcina i-80% amandla kwi-300 ° C; amabanga akhethekileyo (umzekelo, nge-Si/Mo eyongeziweyo) ukuxhathisa i-embrittlement ukuya kutsho ku-40°C ukuze kusetyenziswe i-arctic.

Ukuxhathisa ukonakala:

-G80:Ukuthanda ukugqwala; ifuna i-oyile rhoqo kwiindawo ezifumileyo.

-G100/G120:Ukhetho lubandakanya i-galvanization (i-zinc plated) okanye i-stainless-steel variants (umzekelo, i-316L yezityalo zaselwandle / zekhemikhali). IG100 eGalvanized imelana neeyure ezingama-500+ kwiimvavanyo zokutshiza ityuwa.

Ukudinwa kunye Nokuqina kweMpembelelo:

-G80:Kwanele kwimithwalo emileyo; ukuqina kwempembelelo ≈25 J ku -20°C.

-G120:Ukuqina okungaqhelekanga (>40 J) ngenxa yokongezwa kwe-Ni/Cr; ilungele ukunyuswa okuguquguqukayo (umzekelo, iikhreyini zendawo yeenqanawa).

3. Isicelo-Isikhokelo sokuKhetha esiKhethekileyo

Ukukhetha ibakala elifanelekileyo kukhulisa ukhuseleko kunye neendleko-zobuchule.

Usetyenziso	IBanga elicetyiswayo	Ingqiqo
Ulwakhiwo ngokubanzi	G80	Ixabiso eliphantsi kwimithwalo ephakathi / indawo eyomileyo; umzekelo, isikafula.
Ngaselunxwemeni/Ukuphakamisa eLwandle	I-G100 (iGalvanized)	Amandla aphezulu + ukuxhathisa ukubola; imelana nokugawulwa kwamanzi olwandle.
Ukwembiwa kwemigodi/ekwari	G120	Yenyusa ukuxhathisa ukunxiba kwi-abrasive rock handling; iyasinda kwimithwalo yempembelelo.
Ubushushu obuphezulu (umzekelo, iiMili zentsimbi)	I-G100 (Iyantlukwano enyangwa ngobushushu)	Igcina amandla kufuphi neziko (ukuya kuma-300 ° C).
IiLifts eziBalulekileyo eziDynamic	G120	Ukumelana nokudinwa kukunyuswa kwehelikopta okanye ukufakwa kwezixhobo ezijikelezayo.

4. Ukusilela kuThintelo kunye noLondolozo lwezimvo

-UkuFatigue Faigue:Eyona nto ixhaphakileyo ekulayisheni i-cyclic. IG120 ephezulu yokuchasana nokuqhekeka kokuqhekeka kunciphisa lo mngcipheko.

-I-Corrosion Pitting:Ukulalanisa amandla; Izilingi ze-G100 ezifakwe kwi-galvanized zihlala zi-3× ixesha elide kwiindawo eziselunxwemeni ngokuchasene ne-G80 engagqunywanga.

- Ukuhlolwa:I-ASME igunyazisa iitshekhi zenyanga zokuqhekeka, ukunxiba > 10% ubukhulu, okanye ubude. Sebenzisa uvavanyo lwamasuntswana amagnethi kwikhonkco le-G100/G120.

5. Ukukhuthaza iinguqulelo ezintsha kunye neeNdlela zekamva

-Amakhonkco e-Smart:Amatyathanga e-G120 anezinzwa zoxinzelelo ezizinzisiweyo zokujongwa kwexesha lokwenyani lomthwalo.

- Iingubo:Iingubo ze-Nano-ceramic kwi-G120 ukwandisa ubomi benkonzo kwiindawo ezine-acidic.

- Inzululwazi yezinto eziphathekayo:Uphando kwi-austenitic steel variants for cryogenic lifting (-196 ° C LNG izicelo) .

Ukuqukumbela: Ukuthelekisa amatyathanga kwiBanga leeMfuno zakho

- Khetha i-G80kwiilifti ezimileyo ezingenakonakala.

- Chaza i-G100kwimo engqongileyo eyonakalisayo/eguqukayo efuna amandla alungeleleneyo kunye nokuqina.

-Khetha i-G120kwiimeko ezinzima kakhulu: ukudinwa okuphezulu, ukukrazula, okanye ukunyuswa okuchanekileyo.

Inqaku lokugqibela: Soloko ubeka phambili amatyathanga aqinisekisiweyo ngonyango lobushushu olulandelekayo. Ukukhetha okufanelekileyo kuthintela ukungaphumeleli kwentlekele-inzululwazi yezinto eziphathekayo ngumqolo wokuphakamisa ukhuseleko.
