Kugadzira Maitiro uye Kugadzira Maitiro eCemented carbide rod

Cemented carbide mabara ane simende carbide round rods. Cemented carbide chinhu chakaumbwa chinoumbwa nesimbi inodzoreredza (yakaoma chikamu) uye yekubatanidza simbi (bonding chikamu) inogadzirwa nehupfu metallurgy.

Pane nzira mbiri dzekugadzira dze simende carbide round rods. Imwe nzira ndeye extrusion forming, inova nzira yakakodzera yekugadzira matanda akareba akatenderera. Rudzi urwu rwesimende carbide tsvimbo inogona kutemwa kune chero hurefu hunodiwa nemushandisi panguva yeextrusion process. Zvisinei, kureba kwese hakugoni kudarika 350mm. Imwe yacho ndeye compression molding, inova nzira yakakodzera yekugadzirwa kwebhari pfupi. Sezvinoreva zita, iyo cemented carbide poda inotsikirirwa kuita mold.

Alloy zvinhu zvinogadzirwa nesimbi inodzoreredza uye simbi yekubatanidza kuburikidza nehupfu simbi simbi. Cemented carbide ine nhevedzano yezvakanakisa zvivakwa senge kuomarara kwakanyanya, kupfeka kuramba, simba rakanaka uye kuomarara, kudzivirira kupisa, uye kushora. kunyanya kuoma kwayo kwepamusoro uye kusakara kwekupfeka, iyo inoramba isina kuchinjwa kunyange pakupisa kwe500 °C, uye ichiri nekuoma kwepamusoro pa1000 °C. Carbide inoshandiswa zvakanyanya semidziyo yekushandisa, senge maturusi ekuchinjisa, milling cutters, mapurani, madhiri, maturusi anofinha, nezvimwe zvekucheka simbi yakakandwa, isiri-ferrous simbi, mapurasitiki, kemikari fiber, graphite, girazi, dombo, uye simbi yakajairika, uye inogona zvakare kushandiswa kucheka Kukuya kunyorova kwezvinhu zvakaoma-kuita-kugadzirisa zvakadai sesimbi isingadziviriri kupisa, simbi isina tsvina, yakakwirira manganese simbi, simbi yemidziyo (bhora chigayo, drying cabinet, Z-type mixer, granulator) --- kudzvanya. (ine side-pressure hydraulic press or extruder)-- - Sintering (degreasing furnace, furnace yakabatanidzwa kana HIP low-pressure virace)

Zvinhu zvakasvibirira zvakanyorova, zvakaomeswa, zvakasanganiswa neglue mushure mekuenzanisa, zvino zvakaomeswa uye kushushikana-kusunungurwa mushure mekuumbwa kana kubudiswa, uye yekupedzisira alloy isina chinhu inoumbwa nekudzikisa uye sintering.

Iyo yakashata yearound bar extrusion kugadzirwa ndeyekuti kutenderera kwekugadzira kwakareba. Kuwedzeredza kwediki-dhayamita kutenderera mabara pazasi 3mm, kucheka mativi ese ari maviri kunoparadza humwe huwandu hwezvinhu. Iyo yakareba kureba kwediki-dhayamita yakatenderedza bhaa ye simende carbide, kunowedzera kutwasanuka kweiyo isina chinhu. Ehe, matambudziko ekururama uye kutenderera anogona kuvandudzwa necylindrical kugaya mune inotevera nhanho.

Imwe yacho ndeye compression molding, iyo inoshandiswa kugadzira mabara mapfupi. Sezvinoreva zita, pane mold inotsikirira simende carbide poda. Kubatsira kweiyi simende carbide bar yekugadzira nzira: inogona kuumbwa panguva imwe chete uye kuderedza marara. Rerutsa nzira yekucheka waya uye chengetedza iyo yakaoma zvinhu kutenderera kweiyo extrusion nzira. Iyo iri pamusoro yakapfupikiswa nguva inogona kuchengetedza mazuva 7-10 kune vatengi.

Kunyatsotaura, isostatic kudzvanya zvakare ndeyekuumba. Isostatic kudzvanya ndiyo yakanyanya kunaka kuumba nzira yekugadzira yakakura uye yakareba carbide kutenderera mabara. Kuburikidza nekuvharwa kwepistoni yepamusoro nechepazasi, pombi yekumanikidza inopinza mvura yepakati pakati pe-high-pressure cylinder nerabha yakadzvanywa, uye kudzvanywa kunofambiswa kuburikidza nerabha yakamanikidzwa kuita simende yecarbide poda yekutsikirira-yakaumbwa.

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.
