Hluav taws xob Resistance Welded (ERW) steel kav, tshwj xeeb tshaj yog cov uas ua los ntawm High-Frequency Welding (HFW) thev naus laus zis, yog lub hauv paus ntawm cov txheej txheem niaj hnub no, siv dav hauv kev xa roj thiab roj, kev faib dej, thiab kev siv cov qauv. Ib qho tseem ceeb ntawm qhov txawv ntawm qhov siab - zoo ERW kav dej yog lawv qhov zoo tshaj qhov raug, encompassing meej txheej kab, zoo li phab ntsa thickness, thiab zoo heev roundness. Qhov kev txiav txim siab no tsis yog tsuas yog kev tsim khoom yooj yim xwb; Nws yog ib qho tseem ceeb rau cov yeeb nkab kev ua tau zoo, ua kom yooj yim ntawm kev teeb tsa, pom cov yam ntxwv zoo, thiab kev ua haujlwm zoo. Cov lus zais tom qab qhov tshwj xeeb tshwj xeeb no yog qhov tob tob hauv kev tshawb fawb ntawm siab - zaus induction vuam, cov txheej txheem sophisticated uas tso cai rau kev tswj xyuas nruj ntawm cov vuam tsis thiab cov yeeb nkab kawg geometry. Hebei Huayang Steel Pipe Co., Ltd. leverages txiav-ntug HFW thev naus laus zis los tsim cov kav dej ERW uas tsis tu ncua ua tau raws thiab dhau qhov kev ua siab ntev, ua kom muaj kev ntseeg siab rau ntau hom kev lag luam.
Nkag siab siab -Vuam zaus (HFW) rau ERW Pipes
ERW cov kav dej yog tsim los ntawm cov hlau coils uas tau hloov mus rau hauv daim ntawv cylindrical. Cov npoo ntawm cov sawb yog ces rhuab mus rau forging kub thiab nias ua ke los tsim ib tug khoom - xeev weld. HFW yog ib hom ERW tshwj xeeb uas siv siab - zaus hloov tam sim no (feem ntau 100 kHz txog 700 kHz) los ua kom sov. Cov kauj ruam tseem ceeb thiab cov qauv kev tshawb fawb muaj feem xyuam yog:
1.Edge Cua sov ntawm Induction: Raws li cov hlau sawb ze rau qhov vuam taw tes, siab - zaus tam sim no yog induced rau hauv cov npoo. Vim yog cov nyhuv ntawm daim tawv nqaij thiab qhov sib thooj, qhov tam sim no concentrates ntawm cov npoo ntawm cov sawb, ua kom sov sai rau lub xeev yas (ze li 1200-1400 degree) yam tsis tau yaj tag nrho cov khoom. Qhov cua sov hauv cheeb tsam no yog qhov tseem ceeb rau kev tswj qhov kub thiab txias.
2.Squeeze Siab: Tam sim ntawd tom qab cua sov, precisely tswj nyem yob siv lub siab loj heev rau forge lub rhuab npoo ua ke. Lub siab no tshem tawm cov oxides lossis impurities los ntawm qhov sib txuas, tsim kom muaj zog, huv si, thiab ruaj khov - xeev weld seam.
3.Flash Tshem Tawm: Cov khoom siv ntau dhau (flash) nyem tawm thaum lub sijhawm vuam yog tam sim ntawd txiav tawm ob qho tib si sab hauv thiab sab nraud, ua kom lub ntsej muag du.
4.Cooling thiab Sizing: Cov yeeb nkab welded ces undergoes tswj txias thiab dhau los ntawm sizing rolls kom ua tiav qhov kawg ntawm lub taub thiab roundness.
Yuav ua li cas HFW pab txhawb rau Superior Dimensional Accuracy
Cov yam ntxwv ntawm HFW thev naus laus zis ncaj qha txhais mus rau qhov tshwj xeeb qhov tseeb ntawm ERW kav dej:
1. Localized thiab tswj cua sov
Lub siab - zaus tam sim no lub peev xwm los mloog cov cua sov zoo ntawm cov npoo npoo tso cai rau cua sov sai heev thiab tsis sib xws. Qhov no txo cov cua sov- thaj tsam cuam tshuam (HAZ) thiab txo cov thermal distortion tag nrho ntawm cov yeeb nkab lub cev, uas yog ib qho ua rau muaj qhov tsis raug nyob rau hauv lwm txoj kev vuam.
2. Precise Squeeze Pressure Control
Niaj hnub nimno HFW cov cav tov tau nruab nrog cov txheej txheem tswj cov txheej txheem uas tswj xyuas lub zog sib npaug. Qhov no ua kom muaj qhov sib txawv ntawm cov hlua khi thiab tiv thaiv kev hloov pauv ntawm phab ntsa tuab lossis ovality uas tuaj yeem tshwm sim los ntawm kev thov tsis sib xws.
3. Nruam thiab automated txheej txheem
HFW yog cov txheej txheem tas mus li, tsis siv neeg, uas tso cai rau cov kev ntsuas tsis tu ncua kom khaws cia ntev li ntau lawm. Qhov no txo qis tib neeg kev ua yuam kev thiab hloov pauv, ua rau muaj qhov tseeb qhov tseeb ntawm ib lub yeeb nkab ntev mus rau lwm qhov.
4. Kev soj ntsuam online thiab kev tawm tswv yim
Cov kab HFW Advanced suav nrog tiag tiag- lub sijhawm saib xyuas cov tshuab (piv txwv li, laser ntsuas, eddy tam sim no sensors) uas tsis tu ncua ntsuas cov yeeb nkab qhov ntev thiab vuam zoo. Ib qho kev sib txawv tau pom tam sim ntawd, thiab cov lus tawm tswv yim kho cov txheej txheem tsis ua haujlwm, kom ntseeg tau tias cov yeeb nkab tseem nyob hauv qhov kev cia siab.
