Umqulu owenziwe ngepowder metallurgy method

I-tungsten carbide rollerinobulukhuni obuphezulu, kwaye ixabiso lobunzima bayo litshintsha kancinci ngeqondo lobushushu, kwaye ixabiso lobulukhuni kwi-700 ℃ ngamaxesha angama-4 we-HSS;kunye nemodyuli ye-elasticity, amandla acinezelayo, amandla okuguquguquka, ukuhanjiswa kwe-thermal nazo ziphezulu kunentsimbi yesixhobo ngaphezulu kwexesha eli-1.Ngenxa yomgangatho ophezulu we-thermal conductivity ye-carbide rolls, ngoko umphumo wokutshatyalaliswa kobushushu ulungile, ukuze umphezulu we-roll ubushushu obuphezulu ixesha elifutshane, ukuze imiqulu ngamanzi okupholisa ukungcola okuyingozi kwi-reaction yeqondo lokushisa eliphezulu. ixesha lifutshane.Ke ngoko, i-carbide rolls ixhathisa ngakumbi kwi-corrosion kunye nokukhathala okushushu kunye nokubanda kunezixhobo zentsimbi.

Iirola zeTungsten carbideinokwahlulwa ibe ziintlobo ezimbini ngokwesakhiwo se-integrated carbide roller kunye ne-composite carbide rolls.I-Integral carbide rolls isetyenziswe ngokubanzi kwi-pre-finishing kunye nokugqiba izitendi ze-high-speed wire rod mills (kuquka i-size stands kunye ne-pinch-feeding roll stands), njl njl. yahlulwe yaba yi-carbide composite roll ring kunye ne-carbide composite rolls iyonke.I-carbide composite roll ring ifakwe kwi-roll shaft;i-integrated carbide composite roll iphoswe ngokuthe ngqo kwi-roll shaft ukuze yenze yonke into, esetyenziswa kwii-mills ezinomthwalo omkhulu wokuqengqeleka.
