Cov kauv raj feem ntau tsis tso cai rau tso cov khoom lag luam ntau hauv kev tsim khoom hauv kev siv cov square tes, uas xav kom cov neeg muag khoom tso qee cov khoom lag luam. Txawm li cas los xij, cov tswv lag luam feem ntau tsis muaj cov tsev qiv ntawv loj hauv tsev. Feem ntau ntawm lawv yog cov khoom lag luam sab nraum zoov. Cov kav dej kauv yog inevitable kom lub hnub. Yog li, yuav ua li cas kom paub qhov txawv ntawm xeb thiab xeb ntawm cov kauv raj?
Lub thiaj li hu ua xeb, raws li lub npe qhia, yog ib txheej ntawm xeb uas ntab mus rau lub kauv raj. Nws tuaj yeem raug tshem tawm nrog phuam lossis lwm yam. Yooj yim muab, xeb tsis yog xeb, uas yog qhov qub.
Cov xeb ntawm cov kauv raj yog lub sijhawm ntev. Tsawg kawg yog ib xyoos yog ntau tshaj 1 xyoos, cov kav raj xaim hla cua thiab hnub ci tawm sab nraud sab nraum zoov, thiab cov rusty kauv raj muaj qhov loj thiab me me rau ntawm nws. Qhov no kuj yog ib tug kauv raj xeb thiab xeb. Qhov txawv loj.
Kauv raj yog ib seem sawing ntawm steel cog raj, thiab ces rhuab nyob rau hauv lub nplhaib furnace-perforation-taw txoj kab uas hla-tsev kawm ntawv ncaj-txias-ua yeeb yam taub hau-packaging ua ib tug tsim nyog cov khoom tiav. Siv lub taub sab nraud * phab ntsa thickness. Yog hais tias lub kauv raj muaj ib leeg-sab welding thiab ob-sided vuam, cov welded yeeb nkab yuav tsum xyuas kom meej lub hydraulic xeem, lub tensile lub zog ntawm lub vuam, thiab lub txias dabtsi yog khoov kev ua tau zoo.
