Ukwandisa ukukhuhlana phakathi kwerola yesityuli kunye nepali eshiyekileyo kunye nokwandisa i-engile yomhlathi otyumzayo kunokwenza ibloko yebhola eshiyekileyo enedayamitha enkulu engqukuva ingene kwaye ityumke.Ngoko ke, i-welding flakes enobubanzi obuyi-30 mm kunye nokuphakama kwe-10 mm zixutywe ngezithuba ze-100 mm ebusweni be-roller yokukhanya.Emva kokuba ubunzima obuseleyo bungene kwigumbi lokutyumza, linqunyulwe phantsi kwesenzo sobuso bezinyo, kwaye i-angle yomhlathi otyumzayo yanda, kwaye ingqolowa ephakathi inokufumaneka.Ububanzi (6070mm) bukhulu kakhulu kwaye ipali eshiyekileyo yophukile.
Umphezulu we-welding roller wenziwa nge-arc welding manual, kwaye umphezulu we-double-roller crusher ujongene.Iingongoma eziphambili zokujonga phezulu zezi zilandelayo.
(1) D-65, D-667 kunye ne-506 iintonga ze-welding zikhethiweyo.Ngaphambi kwe-welding, ngokwemiyalelo ye-welding rods, iintonga ze-welding zomisiwe kwaye zifakwe kwi-incubator ukuze zisetyenziswe.
(2) Coca i-fatigue layer ye-roller surface, ihlambulule nge-carbon arc gouging, kwaye ucwangcise umgca wokukhathala we-roller surface ukuze uveze i-roller kwi-base material layer.
(3) Sebenzisa umatshini we-welding we-DC, omele uguqulwe (intonga ye-welding ixhunyiwe kwi-electrode efanelekileyo).Xa i-surface, umatshini we-welding we-AC ufuna i-voltage engekho yomthwalo we-70V, kwaye okwangoku ilawulwa malunga ne-200A.Ukuba i-voltage engekho yomthwalo ingaphantsi kwe-70V, okwangoku kufuneka inyuswe, esekelwe kwi-fusion epheleleyo ye-electrode kunye nesiseko sesinyithi.Umlinganiselo wobubanzi be-weld bead ukuya kumphakamo ukhethwa ngama-31.
4Emva koko ngokulinganayo weld amaleko aliqela D-667 (high-chromium cast iron surfacing rod inokumelana nempembelelo ephezulu kunye nokumelana nokunxiba, ukuqina kwe-HRC48 emva kwe-welding, ukumelana nokunxiba kakuhle, ukuxhathisa ukubola kunye nokumelana ne-cavitation engaphantsi kwama-500 ubushushu obuphezulu) Kufuneka kubekho ubukhulu.Emva kokuba umaleko we-weld we-D-667 uphezulu, umaleko we-D-65 (i-alloy ephezulu ye-alloy intonga i-Cr-Si-Mo-B high-corrosion cast-iron enganyangekiyo kwi-electrode ekwaziyo ukumelana nomphezulu inokumelana. Ukumelana nokunxitywa kwe-abrasive eqinile, iingenelo zale electrode zilungile, akukho slag emva kwe-welding, ukuqina okuphezulu emva kwe-welding HRC60.Gqoka umaleko Uxinzelelo lobunzima bufanayo ukuze i-roller ecinezelayo ihlale isetyhula ngexesha lokusetyenziswa.
3 Isiphelo
Ngokuziqhelanisa nemveliso, i-avareji yobungakanani bamasuntswana e-electrode eshiyekileyo ye-crusher yonyuka ukusuka kwi-40mm ukuya kwi-60mm ngexesha loyilo, okunciphisa umthwalo wemveliso yesixhobo esinyukayo, iphucula ukuguquguquka kwi-roller crusher, kunye nobomi benkonzo i-roller crusher ifikelela kwi-10 ngenyanga, i-pole residual pole iphelele kwiitoni ezingama-50,000.
