Lub zog ntawm cov hlau coils feem ntau yog vim lawv qhov hnyav hnyav, lub zog kinetic tsim los ntawm siab - nrawm nrawm, thiab muaj peev xwm txiav kev phom sij. Cov hlau coils feem ntau yog ua los ntawm cov coils ntawm txias - dov los yog kub - cov ntawv hlau dov thiab tuaj yeem hnyav ntau lossis ntau tshaj kaum tons. Yog tias lawv tswj tsis tau thaum lub sijhawm thauj los yog tuav, lub zog kinetic ntawm lawv cov dov lossis zawv zawg zog tuaj yeem ua kom txaus los rhuav tshem cov teeb meem, ua rau tus kheej raug mob hnyav thiab khoom puas tsuaj. Tsis tas li ntawd, cov npoo ntse ntawm steel coils tuaj yeem tsim cov nyhuv txiav thaum tig los yog txav ntawm qhov nrawm, ua rau muaj kev hem thawj rau cov neeg ua haujlwm.
Los ntawm txoj kev xav, lub zog ntawm lub kauj hlau yog ncaj qha ntsig txog nws qhov loj, ceev, thiab ntug sharpness. Raws li physics formula E=1/2mv², kinetic zog nce nrog lub square ntawm ceev, yog li txawm lub steel kauj dov ntawm ib tug tsawg ceev muaj peev xwm nqa lub zog tseem ceeb. Cov xwm txheej feem ntau muaj xws li coils slipping thaum lub sij hawm nqa, coils raug pov rau pem hauv ntej los ntawm kev sib tsoo ntawm lub tsheb thauj mus los, thiab cov coils dov vim kev cia khoom tsis raug.
Kev tuav ruaj ntseg ntawm steel coils yuav tsum tau ua raws li cov kauj ruam hauv qab no: 1) Siv cov cuab yeej nqa siab, ua kom nws cov load-cov kabmob muaj peev xwm tshaj lub kauj qhov hnyav li ntawm 20%; 2) Ruaj ntseg lub kauj thaum thauj khoom siv tsis yog- plam skids thiab strapping, nrog rau kev pom zoo khi quab yuam tsawg kawg yog 1.5 npaug ntawm lub coil qhov hnyav; 3) Khaws lub kauj rau ntawm lub tiaj tiaj, khoom nto, nrog rau qhov inclination tsis tshaj 5 degrees. Tsis muaj qhov xwm txheej yuav tsum cov neeg ua haujlwm sawv hauv txoj kev ntawm lub kauj uas tuaj yeem yob.
