Tus txheej txheem no yog tus tseem ceeb ntawm HUAYANG txoj kab ntau lawm (piv txwv li cov kav dej ntau lawm (piv txwv li cov kav dej sib tw ntawm cov roj

Ua ntej vuam, huaayang nruj me ntsis tswj ob qhov txuas tseem ceeb kom tsis txhob muaj qhov tsis xws luag:

Leeg Tu: Cov npoo ntawm cov yeeb nkab dawb paug (tsim los ntawm multi-} {-} Kev txwv tsis pub cua npuas hauv Weld. Rau φ48 × 3.5mm scaffolding yeeb nkab tsis muaj dab tsi, Huayang lub tshuab ua noj tsis zoo no ua kom tu ntawm 5 hli ntawm txhua sab ntawm lub leeg.

Kev Txij Nkawm Electrode: Cov khoom tooj liab tooj liab (siv los ua qhov tam sim no) yog polished txhua hnub los tswj lub ntsej muag du (roughness tsawg dua lossis sib luag rau Ra0.8μm). Cov tshuaj no (nrog kev hnav khaub ncaws tob tshaj 0.5 hli) tau hloov tam sim ntawd kom ntseeg tau tias muaj kev sib txawv ntawm kev ua haujlwm tam sim no.

Huaayang lub dog digHlobCov txheej txheem vuam tau muab faib ua peb qib, nrog kev tswj kom meej ntawm kev tam sim no, siab, thiab kub:

Cov yeeb nkab khoob yog clamped los ntawm ob lub tooj liab tooj liab (sab saud thiab qis dua) {{{}}} 3kHz) yog thov. Cov txheej txheem tam sim no los ntawm cov yeeb nkab dawb paug (nrog hluav taws xob kub uas tsa lub zog cua sov txog 1200 degree} Huayang siv cov lus tawm tswv yim tam sim no los kho qhov tam sim no nyob rau hauv lub sijhawm tam sim no rau φ114 × 4.5 hli roj av dawb paug, tam sim no yog kom tsis txhob overheating lossis underhe.

Thaum cov yeeb nkab dawb paug mus txog lub xeev yas melting, nyob tom qab ntawm cov hluav taws xob) thov nyem tawm molting hlau thiab cua, fusing ob sab rau hauv ib qho weld. Kev tshem tawm lub siab kho yog kho raws li cov yeeb nkab phab ntsa tuab: rau 2mm {}} Cov kav nyias nyias, lub siab yog 2mpa (kom tsis txhob muaj cov yeeb nkab deformation); Rau 16mm-tuab kav dej, lub siab yog nce mus rau 5MPA (los xyuas kom meej qhov fusion).

Tom qab vuam, tshaj weld hlaws (qhov siab 1 -}}}}} 2 hli) tsawg dua lossis sib npaug ntawm cov yeeb nkab lub cev). Cov kauj ruam no tsis tsuas yog txhim kho cov yeeb nkab lub ntsej muag tab sis kuj txo cov kev ntxhov siab ntawm Weld, txuas ntxiv rau lub neej pabcuam.

Rau qhov zoo liHlobCov kav dej, Huaayang ua ob qhov kev kuaj pom tseem ceeb los xyuas cov khoom zoo vuam zoo:

Ultrasonic Qhov Ntsuas Kom Qhuav Nrhiav tau: Lub portable ultrasonic ntes scans lub tshuab weld 360 los xyuas cov kev tsis zoo sab hauv (xws li cov kab nrib pleb lossis kev sib kis) nrog 0.5 hli. Tus nqi dhau ntawm Huaayang lub dog digHlobCov yeeb nkab Welds loj dua los yog sib npaug rau 99.5%.

Hydrostatic siab ntsuas: Welded yeeb nkab tau ntim nrog dej thiab nias rau 1.2MPA rau lub siab (piv txwv li 2.4MPA rau 2MPA- rated kav) li 5 feeb. Tsis muaj xau lossis lub siab poob qhia tau tias muaj cov ntawv Weld tsim nyog. Hauv 2023 baoding pheej yig cov vaj tse project, 2,500 tons ntawm φ48 × 3.5mmHlobScaffolding kav txhua tus dhau qhov kev xeem no.

HFW(High {- zaus vuam) yog qhov hloov kho tshiabHlobTshuab, siv 300kHz - 500khz heal-zaus tam sim no kom ua tiav nrawm, sib dhos welding, sib dhos vuam. Txoj kev no yog siv rau HFW Steel Kav (High -} Kev ua tau zooCov Hluav Taws Xob Hluav Taws Xob Welded Hlau Kav), haum rau high - pa lom zem heev (ua haujlwm siab tsawg dua los yog sib npaug li 10mpa) xws li roj thiab roj thauj. Huaayang lubHFW Steel Yeeb NkabVuam kab siv cov kab imported german sms khoom, nrog rau kev siv weld nce 95% ntawm cov hlau hauv paus.

Piv nrog dog digHlob, HFWVuam muaj peb tus tseem ceeb ntawm HUAYANG:

Hloov chaw tooj liab hluav taws xob ncaj qha clamping cov yeeb nkab dawb paug,HFWSiv kev sib tham chev kom tsim lub siab - zaus teb ib ncig ntawm cov yeeb nkab dawb paug. Lub sib nqus teb tsim educes edces tawm ntawm cov yeeb nkab dawb paug, uas tsuas yog cua sov (cua sov tsawg dua los yog sib npaug ntawm cov yeeb nkab tag nrho. Qhov no "cua sov cua sov" zam cov qoob loo grainening ntawm lub hauv paus hlau- × 10 hli HFW Steel Yeeb Nkabblanks, ntug ntsuas kub yog tswj tau zoo nyob rau ntawm 1250℃-1300 degree, thaum lub tshuab yeeb nkab kub tseem qis dua 200 degree.

HFWvuam ceev mus txog 30-60m / min (3 zaug uas muaj dog digHlob), Xav tau synchronous txias kom tiv thaiv weld deformation. Huaayang lubHFWKab yog nruab nrog dej mood cua txias system uas spray omdized {} Qhov no txo lub sijhawm ntawm weld txias lub sijhawm los ntawm 5 feeb (dog digHlob) Txog 30 vib nas this, txhim kho cov khoom siv ntau thaum ua kom pom Weld nplej.

Txhawm rau txhawm rau txhim kho cov tawv ntawmHFW Steel Kav, Huaayang ntxiv tag nrho analing kauj ruam tom qab vuam:

Welded yeeb nkab yog pub rau hauv ib qho kev txuas ntxiv ua kom sov thiab cua sov kom 700 degree}}}}} (recrystallization kub ntawm cov roj carbon hlau);

Nws yog tuav ntawm qhov kub no rau 5 feeb los tshem tawm vuam sib cav sib ceg;

Nws txias rau chav kub ntawm tus nqi ntawm 50℃/ teev kom tsis txhob muaj kev ntxhov siab thermal.

Tom qab annealing, qhov kev cuam tshuam nyuaj ntawm HUAYGANG'sHFW Steel Kav Ntawm - 40℃mus txog ntau dua los yog sib luag rau 60j / cm, sib ntsib ntawm cov roj qis qaum teb thiab roj pipelines.

RauHFW Steel Kav(Tseem Ceeb rau siab -|kev nyab xeeb), Huayang siv ib qho "peb {{{1} - Kev tshuaj ntsuam lub kaw lus" kom paub meej Weld Zoo:

Ua ntej -} vuam kuaj: Txheeb xyuas cov yeeb nkab dawb paug ntawm cov leeg sib txawv (tswj hwm ntawm 0.05mm-0.1mm) thiab induction chev txoj hauj lwm tsawg dua los yog sib npaug rau 0.1mm);
