Zvichatora Nguva Yakadii Kugadzira carbide rods?

Semugadziri we tungsten carbide rods, tinogara tichigamuchira mibvunzo yakawanda senge, "nei zvichitora nguva yakareba kudaro kugadzira carbide rods?". Ichi chinyorwa ndechekukupa mhinduro, uye isu tichatora mienzaniso yekugadzira 200kg carbide round bars.

Maitiro ekugadzira tungsten carbide tsvimbo

A. Gadzirira zvinyorwa

Kazhinji, dhipatimendi rekutenga rinotenga nekuchengetedza remhando yepamusoro tungsten carbide poda uye binder poda.

B. Kusanganisa nekugaya nyoro: 48 maawa

Tungsten carbide poda uye binder poda zvichasanganiswa nekugayiwa nemvura uye ethanol mumushini wekugaya bhora. Kuzvigaya zvakakwana uye kuwana saizi yezviyo yakakodzera, muchina wekugaya bhora unoramba uchigaya kwemazuva maviri.

C. Kupfapfaidza kuomesa: 24 maawa

Mushure mekunyorova, tungsten carbide poda slurry Dryskumusoro mu spray dry tower kwemaawa makumi maviri nemana. Chete kana pfapfaidzo yaomesa mvura mu tungsten carbide poda ndipo panogona kupedzwa nekutsikirira nekunyunguduka zviri nani.

D. Compacting: extrusion 228 maawa;yakaoma-bhegi isostatic kudzvanya 36 maawa (kusanganisira kusunungura kushushikana kwemukati uye kuomesa)

Nzira mbiri huru dzekuumbaari extrusion uye yakaoma-bhegi isostatic kudzvanya. Nzira mbiri idzi dzichadhura nguva dzakasiyana. Iyo extrusion inodhura maawa gumi nemaviri kuti ikwane, uye iyo yakaoma-bhegi isostatic kudzvanya inodhura maawa masere. Munguva yekutsikirira, iyo yekugadzira mumiriri inowedzerwa panguva yeextrusion, nepo iyo yakaoma-bhegi isostatic kudzvanya haidi iyo inoumba mumiriri.

Mushure mekudzvanya, matanda akaumbwa anofanirwa kusunungura kushushikana kwemukati pasi pekugara tembiricha uye humidity nharaunda. Iyi nzira inogona kudzivirira kutsemuka mune inotevera maitiro. Tungsten carbide compacted rods ichapedza nguva yakareba ichiburitsa kushushikana kwemukati, 144 maawa eextrusion, uye maawa makumi maviri nemana kune yakaoma-bhegi isostatic kudzvanya. Zvadaro tungsten carbide compacted rods, mushure me extrusion, ichaiswa muchoto chekuomesa kwemaawa makumi manomwe nematatu, uye tsvimbo mushure mekuoma-bhegi isostatic kudzvanya kwemaawa mana chete.

Kunyangwe iyo yakaoma-bhegi isostatic kudzvanya kuchadhura nguva shoma pane extrusion, inogona chete kushanda pakugadzira matanda makuru ane dhayamita inodarika 16mm.

E. Sintering: 24 maawa

Tungsten carbide yakaomeswa tsvimbo inozopinzwa muvira revacuum. Iyi nzira ichagara kwemaawa makumi maviri nemana. Mushure mekunyungudika, tungsten carbide tsvimbo blanks inoda kugaya uye kuongororwa.

Kupfupisa, nzira huru yekugadzira 200kg tungsten carbide rod blanks inodhura maawa angangoita 324 (13.5 days) yeextrusion uye angangoita maawa zana nemakumi matatu nemaviri (5.5 mazuva) yeiyo dry-bag isostatic kudzvanya, tisingataure nguva yekupedza mukukuya uye. zvichingodaro.

Nekudaro, uine stock yakakwana, haufanirwe kunetseka nezve nguva yekuendesa. Tinogona kuitumira mumazuva matatu. Kana iwe uchifarira tungsten carbide zvigadzirwa uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi peji.
