Hunhu Hunhu hweCemented Carbide

Cemented carbide chinhu che alloy chakagadzirwa neakaomeswa komboni yerefractory simbi uye matrix simbi kuburikidza nehupfu metallurgy process. Nokuti zvigadzirwa zviri muupfu metallurgy uye nzira yekugadzirira yakasiyana. Hunhu hwesimende carbide hwakasiyana. Ngatikurukurei maitiro makuru ecemented carbide mune ino chinyorwa.

1. Hapana kutungamira mune simende carbide. Iyo simende carbide inogadzirwa nehupfu pressure sintering. Nemhaka yokuti nzira yekukanda haina kushandiswa, hapana mutsauko muhuwandu pakati pehupamhi hwepamusoro uye kuumbwa kwemukati, nokudaro kubvisa mutsauko wekushanda kwemagetsi wepanzvimbo iyo inogona kukonzerwa nekusiyana kwehuwandu.

2. Cemented carbide haina dambudziko rekurapa kupisa. Iyo mechanical function ye cemented carbide haishanduki nekupisa uye kutonhora, inongokonzerwa nekupisa kwekupisa panguva yekupisa kana kutonhora. Naizvozvo, kugadziridzwa kweiyo simende carbide kunofanirwa kuitwa kusati kwaitwa sintering process. Mushure mekupisa, inogona chete kugadzirisa nemidziyo yedhaimondi. Iyo mechanic function yecemented carbide inonyanya kutariswa nehuwandu hwecobalt uye saizi yetungsten carbide.

3. Chiyero chePoisson che cemented carbide i 0.21 ~ 0.24. Naizvozvo, cemented carbide mold yemukati dhayamita ine diki shanduko pane simbi mold pasi pechiito chekugadzirisa kushushikana. Saka, saizi yecemented carbide chigadzirwa iri padyo nehukuru hwe mold.

4. Carbide ine high compressive simba. Iyo cobalt yemukati inogona kuona iyo inomanikidza simba. Iko kusimba kwesimba resimende zvigadzirwa zvecarbide ine yakaderera cobalt inogona kusvika kupfuura 6000Mpa, iyo ingangoita kaviri yesimbi.

5. Cemented carbide ine yakaderera coefficient of thermal kuwedzera. Vanhu vanofanirwa kufunga nezve iyi poindi mukugadzira uye kugadzira carbide mold.

6. High thermal conductivity. Iyo inopisa conductivity ye cemented carbide yakakwirira zvakapetwa katatu pane simbi isina tsvina.

7. The elastic deformation uye plastiki deformation ye cemented carbide idiki.

8. Chinonyanya kufarirwa hunhu hwecemented carbide ndeyekuoma kwayo kwakanyanya uye yakakwirira kupfeka kuramba. Nguva yekushandisa tungsten carbide yakareba kudarika simbi isina tsvina.

Parizvino, ma carbides akasimirirwa anoshandiswa mu molds yemumba anonyanya kuumbwa ne tungsten uye cobalt.
