Chii chinonzi Tungsten Carbide Roller

Nekukurumidza kusimudzira kweindasitiri yesimbi, kuvandudza kubuda kwesimbi uye kuvandudza mwero wekushandiswa uye kugadzirwa kwechigayo, kuderedza nguva yekuvhara kwechigayo, kutora tungsten carbide roller ine hupenyu hurefu hwebasa inzira yakakosha. Iyo simende carbide roller, inozivikanwawo secemented carbide roller ring, inoreva mupumburu wakagadzirwa netungsten carbide uye cobalt kuburikidza nehupfu metallurgical nzira.

Iyo tungsten carbide roller inogona kukamurwa kuita marudzi maviri akabatanidzwa uye anoumbwa zvinoenderana nechimiro chechimiro. Integral tungsten carbide roller yakashandiswa zvakanyanya mu-pre-precision rolling uye kupedzisa zvigayo zveakakwira-kumhanya waya anotenderedza zvigayo. Iyo inosanganiswa cemented carbide roller inoumbwa kuburikidza ne tungsten carbide uye zvimwe zvinhu. Iro composite carbide rollers inokandwa zvakananga mumugodhi we roller, iyo inoshandiswa kune guyo rinoputika rine mutoro unorema.

Iyo carbide roll ine kuomarara kwepamusoro uye kukosha kwayo kwekuoma kunosiyana diki netembiricha. Iko kukosha kwekuoma pasi pe700 ° C ndeye 4 nguva yakakwirira kudarika simbi yepamusoro. Iyo elastic modulus, kumanikidza simba, kubhenda simba, uye kupisa conductivity zvakare ka1 nguva yakakwirira kupfuura simbi yekushandisa. Sezvo thermal conductivity yecemented carbide roll yakakwira, kupisa kwekupisa mhedzisiro yakanaka, saka iyo pamusoro peiyo roll iri pasi pekushisa kwakanyanya kwechinguva chidiki uye nekudaro iyo yakanyanya-tembiricha yekuita nguva yekusvibiswa kunokuvadza mumvura inotonhorera uye roll ipfupi. Naizvozvo, tungsten carbide rollers inoshingirira mukuora uye kutonhora nekupisa kuneta kupfuura mudziyo wesimbi rollers.

Kuita kwetungsten carbide rollers kune hukama nezviri mukati mebhondi yesimbi chikamu uye saizi ye tungsten carbide zvimedu. Iyo tungsten carbide inenge 70% kusvika 90% yehuwandu hwekuumbwa uye chiyero chepakati chepakati i μm ye 0.2 kusvika 14. Kana iyo metal bond content yakawedzerwa kana kuwedzera saizi ye tungsten carbide ndeye, kuoma kwe simenti carbide kunoderera. , uye kuoma kunovandudzwa. Simba rekukotama retungsten carbide roller mhete inogona kusvika 2200 MPa. Iko kuoma kwesimba kunogona kusvika (4 ~ 6) × 106 J / ㎡, uye iyo HRA iri makumi manomwe nesere kusvika makumi mapfumbamwe.

Iyo tungsten carbide roll ine yakagadzikana mhando uye yakakwirira kugadzirisa iko nekunaka kupfeka uye kukanganisa kuramba. Carbide roller inoshandiswa zvakanyanya kutenderedza tsvimbo, waya, simbi yakarukwa, uye isina musono pombi yesimbi, iyo inovandudza zvakanyanya kushanda zvakanaka kwechigayo.

Kana iwe uchifarira tungsten carbide rollers uye uchida rumwe ruzivo uye ruzivo, unogona KUTITA NEI runhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi pepeji.
