UkuTyibilika koThintelo kunye naManyathelo okuLawula kwiTandem yokuGqama eQwayo

I-Slip phenomenon yenzeka ngexesha lenkqubo yokuqengqeleka, oko kukuthi, ukutyibilika kwesalamane phakathi komcu kunye neimiqulu yokusila, ngokwenene, indawo ye-deformation ye-strip ithathelwe indawo ngokupheleleyo yi-front or back zone slip.Isenzeko se-Slip senzeka kancinane sichaphazela umgangatho womphezulu kunye nesivuno somcu, okanye kubangele imfumba eyophukileyo yeengozi zentsimbi, kuphando oludlulileyo, abantu bakholisa ukuba phambi kwexabiso lokutyibilika okanye ubungakanani bexabiso elipheleleyo le-angle engathathi hlangothi njenge isiseko sokumisela ukuba nokwenzeka kokutyibilika, ukuba lincinci ixabiso lokutyibilika langaphambili okanye i-engile engathathi hlangothi, okukhona kunokwenzeka ukuba kutyibilike isenzeko.Enyanisweni, oku akukho nzululwazi kakhulu.Umzekelo, kubatandem ilitye lokusila elibandayo, i-angle engathathi hlangothi yesigxina sokugqibela, ixabiso elipheleleyo le-slip yangaphambili kufuneka libe lincinci kakhulu kunezokuqala ezimbalwa, kodwa oku akuthethi ukuba i-stand inokwenzeka ukuba iqhube.

1. Isantya sokuqengqeleka

Ngokunyuka kwesantya sokuhamba, ubukhulu befilimu ye-lubricant buyanda, i-coefficient of friction iyancipha, amathuba okunyuka kwe-slippage ayanda, kwaye inkqubo yokuguqa ingazinzi.Kodwa ngenxa yemveliso ye-rolling yanamhlanje, indlela yokuphucula ukusebenza kakuhle kwemveliso, i-high-speed rolling ibe yinjongo yomgca wokuvelisa, ngoko ke ekuthinteleni nasekulawuleni i-slippage akufanele kube yindleko yesantya njengexabiso.

2. Inkqubo yokuthambisa

Kubandakanya iintlobo ezahlukeneyo zokuthambisa ulwelo, ugxininiso, ubushushu, njl. njl., zichaphazela ubukhulu befilimu ye-lubricant ngotshintsho kwi-viscosity.Ukwenzela iTandem Cold Mill, ukhetho lwenkqubo yokuthambisa ludlala indima ephambili ekuthinteleni nasekulawuleni i-slippage yenye yeendlela eziphambili.Ngokuhlalutya, sinokwazi ukuba ngokunyuka kwe-viscosity ye-lubricating fluid, ubukhulu befilimu ye-oyile yokuthambisa buyanda, i-coefficient ye-friction iyancipha, kwaye, njengoko ugxininiso lukhula kwaye ubushushu buyancipha, i-viscosity ye-lubricating fluid iyanda.Ngaloo ndlela, kubailitye lokungqusha elibandayoithanda ukutyibilika kwirack (idla ngokuba yi-penultimate rack), unokuthintela ukutyibilika ngokunciphisa ngokufanelekileyo ukuxinana kolwelo lokuthambisa kunye nokuphucula ubushushu bolwelo lokuthambisa.

3. Inkqubo yoxinzelelo

Ngokunyuka kwe-post-tension, i-deformation zone lubrication layer layer inyuka, ukuze kube lula ukutyibilika i-rack, inokwehliswa ngokufanelekileyo yi-post-tension ukukhusela i-slippage.

4. I-Mill Rolluburhabaxa

Ubunzima bokuqengqeleka buchaphazela ubukhulu becala i-coefficient ye-friction, njengoko i-roll roughness iyancipha, i-coefficient ye-friction nayo iyancipha, ukutyibilika kulula ukwenzeka.Ngokuqhelekileyo, uburhabaxa kunye netoni eqengqelekayo inxulumene ngokusondeleyo nokutshintshwa kwangethuba kwemiqulu ukunceda ukuthintela ukutyibilika.
