Thawj kauj ruam yog los txhais raws nraim li "tsis muaj welds" txhais tau tias.
Ib qho tiag tiag -piece, seamless tsim yuav tsum tsis muaj fusion welds, tsis muaj welded los ua ke cov pob qij txha, thiab tsis muaj cov khoom muab tub lim nyob qhov twg los ntawm qhov qub dawb paug los ntawm lub npoo thiab lub log disc. Cov khoom tiav lawm yuav tsum tau muab los ua ib qho -cov khoom sib txuas tuaj yeem nkag mus rau ib tus lej kub. Txawm li cas los xij, qee cov khoom lag luam hauv khw tsuas yog muab "kev sib khi tsis sib haum." Nyob rau hauv cov ntaub ntawv no, lub ntug nws tus kheej yuav raug tsim los ntawm steel tubing los yog ib tug puag ncig steel dawb paug tsis muaj vuam, thaum lub log disc tseem yuav tsum tau welded rau lub ntug thaum lub sij hawm sib dhos. Hauv lwm lo lus, cov vuam tau yooj yim tau txav los ntawm lub npoo mus rau lub npoo - mus rau - disc sib koom, yog li qhov kev txhim kho qhov tseeb yuav tsis tshua muaj txiaj ntsig ntau dua li nws lub suab. Cov kev qhia tshwj xeeb yuav tsum yog li no kom meej meej txoj kev tsim khoom, thiab tus neeg muag khoom yuav tsum tau hais txog txoj kev tsim ntawm cov duab kos. Tsis tas li ntawd nco ntsoov tias tag nrho forged khoom log dawb paug belongs rau cov khoom sib txawv. Nws yog cov khoom forged disc nrog ua ntej -machined lossis reserved center bore, feem ntau yog siv rau saw log, tsav log, clamping rollers, thiab cov khoom zoo sib xws. Nws yuav tsum tsis txhob tsis meej pem nrog lub log dawb.
Cov kauj ruam thib ob yog muab cov kev ua haujlwm tiav; txwv tsis pub, tus neeg muag khoom hais lus tsis ncaj qha sib piv.
Cov neeg muag khoom feem ntau suav lawv cov nqi raws li cov khoom siv, qhov ntev, qhov xav tau ntawm machining, txiav txim kom muaj nuj nqis, thiab kho qhov chaw. Yam tsawg kawg nkaus, koj yuav tsum muab tag nrho cov geometry, load ib lub log thiab qag load, kev khiav hauj lwm ceev, seb lub log yog tsav, pib-nres zaus, siv rail los yog log tsheb profile qauv, thiab cov kev pab cuam qhov kub thiab txias. Yam yuav tsum tau muaj kev nyab xeeb tuaj yeem sib txawv ntawm kev lag luam. Cov cuab yeej siv dav dav thiab cov cuab yeej nqa nqa, piv txwv li, yog tsim los rau cov xwm txheej sib txawv heev. Rau qhov qis-kev siv kub, qis- qhov kub thiab txias cuam tshuam yuav tsum tau teev tseg nyias. Raws li txoj cai tswjfwm, qhov kev tsim qauv thiab cov khoom siv tso cai rau nws, lub log txoj kab uas hla loj dua feem ntau yog qhov zoo dua vim tias nws tuaj yeem pab txo lub log - kev sib cuag kev sib tw.
Cov kauj ruam thib peb yog cov ntaub ntawv pov thawj, thiab ob daim ntawv pov thawj ywj pheej yuav tsum muaj ib txwm xav tau.
Ib qho ntawm cov khoom qis tshaj plaws - tus nqi ntxiab hauv cov khoom lag luam no yog cov khoom siv tsis raug -piv txwv li, cov pa roj carbon zoo tib yam tau muab los ua cov hlau alloy, lossis qis dua - qib steel qauv raug nthuav tawm raws li qib siab dua - qib ib. Qhov no tuaj yeem ua rau poob qis hauv lub zog, hnav tsis kam, thiab cuam tshuam kev ua haujlwm. Tsis txhob cia siab rau daim ntawv pov thawj khoom ib leeg. Nug rau ob qho tib si steel zeb daim ntawv pov thawj cov khoom siv thawj zaug thiab cov ntaub ntawv pov thawj spectrometer tuaj. Ob daim ntawv yuav tsum tau traceable rau tib lub tshav kub los yog batch naj npawb ua ntej cov khoom yuav raug txiav txim kom raug. Kev tshuaj xyuas tshuaj yuav tsum npog tsib lub ntsiab lus tseem ceeb thiab, yog tias tsim nyog, suav nrog alloying lossis microalloying cov ntsiab lus xws li chromium, nickel, molybdenum, thiab vanadium. Cov pa roj carbon sib npaug yuav tsum nyob hauv cov kev txwv uas tau teev tseg hauv kev pom zoo, thaum leej faj thiab phosphorus yuav tsum tau tswj nruj me ntsis. Cov ntaub ntawv qib thiab cov qauv siv tau kuj txawv raws li daim ntawv thov. Hnyav- lub luag haujlwm railway freight log, crane thiab chaw nres nkoj / mining log, thiab lub log rau export rail tej yaam num yuav ua raws li cov qib sib txawv thiab cov qauv. Xaiv cov khoom tsim nyog qib thiab tus qauv raws li qhov kev ua haujlwm tiag tiag es tsis yog luam tawm lwm tus neeg muag khoom qhov tshwj xeeb.
