Density yeTungsten Carbide

Tungsten Carbide, inozivikanwa semeno eindasitiri, inowanzoitika yakadzika pasi chigadzirwa. Iyo ine mukurumbira nekuda kwehunhu hwayo hwakanaka hunosanganisira kuomarara kwepamusoro, kusimba kwepamusoro, kusimba kwepamusoro, kusapfeka, uye kusagadzikana kwemarara, kuitira kuti, inogona kugadzirwa kuita zvidimbu zvakasiyana-siyana zvekuchera, zvicherwa, maturusi ekuchera matombo, maturusi emigodhi, zvipfeko zvekupfeka, cylinder liners. , zvichingoenda zvakadaro. Muindasitiri iyi, tichaisa akawanda ma parameter kuyedza uye kuona kuti tungsten carbide zvigadzirwa ndezvemhando yepamusoro. Muchikamu chino, iyo yekutanga chimiro chemuviri, density, ichataurwa nezvayo.

Chii chinonzi density?

Density indekisi yakakosha yemuchina kuratidza huwandu hwesimende carbide pavhoriyamu yeyuniti. Iro vhoriyamu yatataura pano, inosanganisira vhoriyamu ye pores muzvinyorwa. Zvinoenderana nehurongwa hwepasi rose hwemayunitsi uye zviyero zvemutemo zvekuChina, density inomiririrwa nechiratidzo ρ, uye unit of density ikg/m3.

Kuwanda kwe tungsten carbide

Pasi pemagadzirirwo akafanana ekugadzira uye maparamendi akafanana, kuwanda kwesimende carbide kuchachinja nekuchinja kwemakemikari kuumbwa kana kugadziridzwa kweyero yezvigadzirwa.

Izvo zvakakosha zveYG akateedzana simende carbides ndeye tungsten carbide hupfu uye cobalt hupfu. Mune mamwe mamiriro ezvinhu, sezvo cobalt yemukati inowedzera, iyo alloy density inodzikira, asi kana kukosha kwakakosha kwasvikwa, density fluctuation range idiki. Density yeYG6 alloy is 14.5-14.9g/cm3, density yeYG15 alloy is 13.9-14.2g/cm3, uye density yeYG20 alloy i13.4-13.7g/cm3.

Izvo zvakakosha zveYT akateedzana cemented carbide ndeye tungsten carbide poda, titanium carbide poda, uye cobalt hupfu. Pasi pemamwe mamiriro ezvinhu, sezvo zviri mukati metitanium carbide poda inowedzera, kuwanda kweiyo alloy kunoderera. YT5 alloy density 12.5-13.2g/cm3, YT14 alloy density 11.2-12.0g/cm3, YT15 alloy density 11.0-11.7g/cm3

Zvinhu zvikuru zveYW series cemented carbide itungsten carbide powder, titanium carbide powder, tantalum carbide powder, niobium carbide powder, uye cobalt powder. Density yeYW1 alloy i12.6-13.5g/cm3, density yeYW2 alloy i12.4-13.5g/cm3, uye density yeYW3 alloy i12.4-13.3g/cm3.

Nekuda kwehuremu hwayo, carbide yakasimwa inogona kugadzirwa kuita zvigadzirwa zvakasiyana-siyana, senge mechanical counterweights, huremu tsvimbo dzinoshandiswa mumaindasitiri ekuchera akadai seoiri, wachi pendulum, maballasts ekufambisa chikepe, kufambisa chikepe, nezvimwe. ,  icho chinogona kuona kuenzana kwezvinhu zviri kushanda kana kuti zvakamira, kana kuchengetedza zvakanyanya kushanda kwevashandi.

Zvinhu zve tungsten carbide density

Density inoenderana nekuumbwa kwezvinhu, raw material ratio, microstructure, kugadzirwa kwemaitiro, process paramita, nezvimwe zvinhu. Kazhinji kutaura, iyo minda yekushandiswa yemasimende carbides ane densities akasiyana zvakare akasiyana. Izvi zvinotevera zvinonyanya kuunza izvo zvinofurira zvinhu zvealloy density.

1. Kuumbwa kwezvinhu

Cemented carbide inogona kuumbwa nehupfu mbiri, tungsten carbide hupfu (WC hupfu) uye cobalt hupfu (Co hupfu), kana matatu hupfu: WC hupfu, TiC hupfu (titanium carbide hupfu) uye Co hupfu, kana kunyange WC hupfu. Upfu, TiC hupfu, TaC hupfu (tantalum carbide hupfu), NbC hupfu (niobium carbide hupfu), uye Co hupfu. Nekuda kwekuumbwa kwakasiyana kwezvinhu zvealloy, kuwanda kweiyo alloy kwakasiyana, asi zvikamu zvakafanana: density yeYG6 alloy ndeye 14.5-14.9g/cm³, density yeYT5 alloy ndeye 12.5-13.2g/ cm³, uye density yeYW1 alloy ndeye 12.6-13.5g/cm³.

Kazhinji kutaura, kuwanda kwe tungsten-cobalt (YG) simende carbide inowedzera nekuwedzera kweWC poda yemukati. Semuenzaniso, density yealloy ine WC poda ye94% (YG6 alloy) ndeye 14.5-14.9g/cm³, uye iyo WC poda yemukati Iyo density ye85% alloy (YG15 alloy)iri 13.9-14.2g/cm³.

Kuwanda kwe tungsten-titanium-cobalt (YT) yakaoma alloys inoderera nekuwedzera kweTiC powder content. Semuenzaniso, kuwanda kwema alloys ane TiC hupfu ye5% (YT5 alloy) ndeye 12.5-13.2g/cm³, uye TiC hupfu huri 15%. Density yealloy (YT15 alloy) ndeye 11.0-11.7g/cm³.

2. Microstructure

Porosity inonyanya kukonzerwa nemapores uye shrinkage uye chiratidzo chakakosha chekutonga kunaka kwecemented carbide. Zvikonzero zvikuru zvekuumbwa kwecemented carbide pores zvinosanganisira kupisa-kupisa, organic inclusions, simbi inclusions, urombo hwekutsikirira zvivakwa, uye kusaenzana kuumbwa.

Nekuda kwekuvapo kwepores, iyo chaiyo density yealloy ishoma pane theoretical density. Iyo yakakura kana yakawanda pores, iyo shoma dense iyo alloy iri pahuremu hwakapihwa.

3. Nzira yekugadzira

Maitiro ekugadzira anosanganisira poda metallurgy process uye jekiseni molding tekinoroji. Kukanganisa senge carburizing, under-burning, foiling, bubbling, peeling, uye uncompacting panguva yekutsikirira uye sintering zvinotungamira mukudzikira kwehuremu hwesimende carbide.

4. Nzvimbo yekushanda

Kazhinji, nekuchinja kwekushisa kana kumanikidzwa, vhoriyamu kana density yealloy ichachinjawo zvinoenderana, asi shanduko idiki uye inogona kufuratirwa.

Kana iwe uchifarira tungsten carbide zvigadzirwa uye uchida rumwe ruzivo uye ruzivo, unogona kutibata.
