Iyini i-Tungsten Carbide Roller

Ngokuthuthuka okusheshayo kwemboni yensimbi, ukwenza ngcono ukuphuma kwensimbi kanye nokwenza ngcono izinga lokusebenzisa kanye nokukhiqiza kwesigayo esigaywayo, ukunciphisa izikhathi zokuvala umshini wokugaya, ukwamukela i-tungsten carbide roller enempilo ende yesevisi kuyindlela ebalulekile. I-carbide roller enosimende, eyaziwa nangokuthi iringi ye-carbide roller, isho umqulu owenziwe nge-tungsten carbide ne-cobalt ngendlela ye-powder metallurgical.

I-tungsten carbide roller ingahlukaniswa ngezinhlobo ezimbili ezihlangene futhi ezihlanganisiwe ngokusho kwesakhiwo sesakhiwo. I-Integral tungsten carbide roller isetshenziswe kabanzi ekugoqeni okunembayo kanye nezitendi zokuqedela zezigayo zokugingqa izintambo ezinesivinini esikhulu. I-roller ye-carbide eyinhlanganisela ehlanganisiwe ihlanganiswa nge-tungsten carbide nezinye izinto. I-carbide rollers ehlanganisiwe iphonswa ngqo ku-roller shaft, esetshenziselwa umshini wokugoqa ngomthwalo osindayo.

I-carbide roll inobunzima obuphezulu futhi ukubaluleka kwayo kokuqina kuyahlukahluka kuncane kakhulu ngezinga lokushisa. Inani lokuqina elingaphansi kuka-700 ° C liphakeme izikhathi ezingu-4 kunensimbi enesivinini esikhulu. I-elastic modulus, amandla acindezelayo, amandla okugoba, kanye ne-thermal conductivity nakho kuphakeme isikhathi esingu-1 kunensimbi yethuluzi. Njengoba i-thermal conductivity ye-cemented carbide roll iphezulu, umphumela wokushisa ukushisa muhle, ngakho-ke ingaphezulu le-roll lingaphansi kwezinga lokushisa eliphakeme isikhathi esifushane futhi ngaleyo ndlela isikhathi sokuphendula izinga lokushisa eliphezulu lokungcola okuyingozi emanzini okupholisa kanye umqulu mfishane. Ngakho-ke, ama-tungsten carbide rollers amelana kakhulu nokugqwala nokukhathala okubandayo nokushisayo kunamarola ensimbi amathuluzi.

Ukusebenza kwe-tungsten carbide rollers kuhlobene nokuqukethwe kwesigaba sensimbi yebhondi kanye nobukhulu bezinhlayiya ze-tungsten carbide. I-tungsten carbide icishe ibe ngu-70% kuya ku-90% wengqikithi yokwakheka kanye nosayizi wezinhlayiyana omaphakathi ngu-μm ka-0.2 kuya ku-14. , futhi ukuqina kuyathuthukiswa. Amandla okugoba e-tungsten carbide roller ring angafinyelela ku-2200 MPa. Ukuqina komthelela kungafinyelelwa (4 ~ 6) × 106 J / ㎡, futhi i-HRA ingu-78 kuya ku-90.

I-tungsten carbide roll inekhwalithi ezinzile kanye nokunemba okuphezulu kokucubungula ngokuguga okuhle kakhulu kanye nokumelana nomthelela. I-Carbide roller isetshenziswa kakhulu ukugingqa induku, intambo yocingo, insimbi enentambo, kanye nepayipi lensimbi elingenamthungo, elithuthukisa kakhulu ukusebenza kahle kwesigayo.

Uma uthanda amarola e-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi kwekhasi.
