Roll eyenziwe nge-powder metallurgy method

I-tungsten carbide rolleribe nobulukhuni obuphezulu, futhi inani lobulukhuni bayo lishintsha kancane ngezinga lokushisa, futhi inani lokuqina ku-700 ℃ liyizikhathi ezingu-4 ze-HSS;kanye ne-modulus yokunwebeka, amandla acindezelayo, amandla aguquguqukayo, ukuqhutshwa kokushisa nakho kuphakeme kunensimbi yamathuluzi isikhathi esingaphezu kwesi-1.Ngenxa ye-thermal conductivity ye-carbide rolls, ngakho-ke umphumela wokushisa ukushisa muhle, ukuze indawo yokushisa ibe sezingeni eliphezulu lokushisa isikhathi esifushane, ukuze imiqulu ngamanzi apholisayo okungcola okuyingozi ekuphenduleni kokushisa okuphezulu. isikhathi sifushane.Ngakho-ke, ama-carbide rolls amelana kakhulu nokugqwala nokukhathala okushisayo nokubanda kuneroli lensimbi yamathuluzi.

I-tungsten carbide rollersingahlukaniswa ngezinhlobo ezimbili ngokuya ngesakhiwo se-integrated carbide roller kanye ne-composite carbide rolls.I-Integral carbide rolls isetshenziswe kakhulu ezindaweni zokuqeda ngaphambi kokuphothula kanye nezitendi zokugaywa kwezintambo ezinesivinini esikhulu (okuhlanganisa nezitendi zokulinganisa kanye nezitendi zokuncisha ukudla), njll. Imiqulu eyinhlanganisela ye-carbide yenziwe nge-carbide nezinye izinto, futhi ingaba ihlukaniswe yaba yi-carbide composite roll ring kanye ne-carbide composite rolls iyonke.I-carbide composite roll ring ifakwe ku-roll shaft;i-integrated carbide composite roll iphonswa ngokuqondile ku-roll shaft ukuze yakhe yonke, esetshenziselwa izigayo ezinomthwalo omkhulu wokugoqa.
