Umahluko phakathi kwe-tungsten carbide rolls kunye ne-ceramic rolls

Ukusuka kwimbono yokwakheka kwezinto, imiqulu ye-carbide enesamente ilungiswa ikakhulu yinkqubo yesinyithi somgubo ngenkqubo yesinyithi yomgubo ngokusebenzisa iikhompawundi zetsimbi eziphikisayo (ezifana ne-tungsten carbide WC, titanium carbide TiC, njl. cobalt Co, nickel Ni, njl) njengesigaba sokubopha. Olu ludibaniso olukhethekileyo lwezixhobo lunika i-tungsten carbide rolls iqondo eliphezulu lobunzima, ukuxhathisa ukunxiba kunye nokumelana nokudinwa kwe-thermal, okubenza bakwazi ukujamelana nokugqithisa okukhulu kunye nokukrazula kobushushu obuphezulu, uxinzelelo oluphezulu kunye neenkqubo zokuqengqeleka ngesantya esiphezulu. I-ceramic roll isekelwe kwi-ceramic material kwaye iqhutywe yinkqubo ekhethekileyo. Izinto ze-ceramic ngokwazo zinobunzima obuphezulu kakhulu kunye nokumelana nokugqwesa okugqwesileyo, okwenza ukuba i-ceramic roll iqhube kakuhle kwinkqubo yokuqengqeleka, ngakumbi kwimeko yeemfuno eziphezulu zokugqiba umphezulu kunye nokuxhathisa ukubola komqulu.

Ngokubhekiselele kwiimpawu zokusebenza, ii-tungsten carbide rolls ziyaziwa ngokuxhathisa ukunxiba kunye nokumelana nokudinwa kwe-thermal. Inobunzima obuphezulu kunye nokuzinza okuhle kwe-thermal, kwaye inokuhamba ngokuzinza ixesha elide kwindawo yokushisa ephezulu kunye nomthwalo ophezulu wokuqengqeleka, okuphucula kakhulu ukusebenza kakuhle kwe-rolling Mill. Ukongeza, i-tungsten carbide rolls nayo ine-conductivity entle ye-thermal, enokuthi ikhuphe ngokukhawuleza ubushushu obuveliswe ngexesha lenkqubo yokuqengqeleka, ukunciphisa ubushushu bomphezulu wemiqulu, kunye nokunciphisa umonakalo woxinzelelo lwe-thermal kwimiqulu. I-Ceramic rolls, ngakolunye uhlangothi, ibonakaliswe ngobunzima bayo obuphezulu, ukuxhatshazwa kwe-corrosion kunye nokuzinza okuphezulu kweqondo lokushisa. Iipropati ezikhethekileyo zezixhobo ze-ceramic zenza ukuba ii-ceramic rolls zingabi lula ukuchithwa ngamachiza ngexesha lenkqubo yokugoqa, kwaye inokugcina ukugqiba kunye nokuchaneka kwendawo yokuqengqeleka ixesha elide. Ngelo xesha, imiqulu ye-ceramic inokugcina ukusebenza okuzinzile kwiindawo eziphezulu zokushisa, kwaye ayiyi kuguqula okanye ithobe ngenxa yokunyuka kweqondo lokushisa.

Ngokwesicelo, imiqulu ye-carbide ene-cemented isetyenziswa ngokubanzi kwimveliso yentsimbi, i-non-ferrous metals, i-alloy materials kunye namanye amashishini ngenxa yeempawu zabo ezintle. Ngokukodwa kwiindawo eziphakamileyo ezinomthwalo ophezulu, ezifana ne-high-speed wire rod rod rolling mills kunye nokugqiba ii-rolling mills, i-carbide rolls ene-cemented idlala indima engenakulinganiswa. Imiqulu ye-Ceramic isetyenziswa ngokubanzi kwimigca yokuvelisa eshushu kunye nebandayo kwishishini lentsimbi, imveliso ye-ceramic, i-glass processing kunye ne-electronics industry ngenxa yobunzima bayo obuphezulu, ukumelana nokugqwala kunye nokuzinza okuphezulu kweqondo lokushisa.
