Zvigadzirwa zvesimbi zveTungsten zvine 18% tungsten, tungsten simbi ndeye simende carbide, inonziwo tungsten-titanium alloy.Iko kuomarara ndeye 10K pachiyero cheVickers, yechipiri chete kune diamond.Nekuda kweizvi, tungsten simbi zvigadzirwa, ine hunhu hwekusava nyore kupfeka.Zvigadzirwa zveTungsten carbide zvinowanzo shandiswa mumidziyo yelathe, mabheti ekurovera, mabhiti ekucheka magirazi, kucheka mataira, kuomarara, kusatya kuvharisa, asi brittle.Isimbi isingawanzoitiki.
Tungsten carbide sintering moulding:
Tungsten carbide sintering molding ndeyekudzvanya hupfu kuitawo zvinhu, wozopinda muchoto chekupisa uchipisa kune imwe tembiricha 〔sintering tembiricha〕, woichengeta kwenguva yakati (nguva yekuchengetedza kupisa), wozoitonhodza pasi, kuitira kuti uwane tungsten simbi zvinhu nekuita kunodiwa.
Iyo tungsten carbide sintering process inogona kukamurwa kuita matanho mana ekutanga:
1: kubviswa kwemugadziri wekugadzira, kunyura nguva yekutanga nekuwedzera kwekushisa, iyo yekugadzira inowora zvishoma nezvishoma kana kunyungudutswa, isingabatanidzwe kubva mumuviri wakanyungudutswa, panguva imwe chete, iyo inoumba mumiriri zvakanyanya kana zvishoma kune iyo sintered body. iyo kabhoni inowedzera, kuwanda kwekabhoni kuwedzera kuchava nemhando yekugadzira agent, nhamba ye sintering process uye iyo yakasiyana uye shanduko.
Powder pamusoro oxides yakaderedzwa, mu sintering tembiricha, haidrojeni inogona kuderedzwa cobalt uye tungsten oxides, kana vacuum kubviswa anoumba agent uye sintering, kabhoni uye okisijeni reaction haina kusimba.Powder particles inobvunza kushushikana kwekusangana kunobviswa zvishoma nezvishoma, iyo yakasungwa simbi poda yakatanga kuburitsa kudzoka uye kusanganisazve zvigadzirwa, kupararira kwepamusoro kwakatanga kuitika, simba rebriquette rakavandudzwa.
2: yakasimba chikamu sintering nhanho (800 ° c - eutectic tembiricha)
Pakupisa kusati kwabuda kwechikamu chemvura, kunze kwekuenderera mberi kwechiitiko chinoitika muchikamu chakapfuura, kusimba-chikamu chekuita uye kupararira kunowedzera, kuyerera kwepurasitiki kunowedzerwa, uye muviri wakasvibiswa unoratidzika kudzikira zvakanyanya.
3: Liquid phase sintering stage (eutectic tembiricha - sintering tembiricha>)
Kana chikamu chemvura chikaonekwa mumutumbi wakanyungudutswa, chibvumirano chinopedzwa nekukurumidza, chichiteverwa nekristaro shanduko yekugadzira iyo yakakosha sangano uye chimiro cheiyo alloy.
4: Kutonhora Danho (Sintering Temperature - Room Temperature>)
Mune ino nhanho, iyo tungsten simbi iyo sangano uye chikamu chinoumbwa neakasiyana mamiriro ekutonhora uye inoburitsa dzimwe shanduko, iwe unogona kushandisa iyi ficha, kupisa kurapwa kwetungsten simbi kuvandudza yayo yemuviri uye michina zvimiro.
Tungsten tsvimbo zvigadzirwa zvakatenderera kana square tungsten.Tungsten isimbi yakaoma kwazvo, yakakora uye ine tembiricha yekunyungudika yepamusoro pechero simbi: 6,192°F (3,422°C).Chinhu chemakemikari chine nhamba yeatomu 74. Ikemikari ine nhamba yeatomu ye 74. tungsten ine huturu hwekugwinya uye inokanganiswa zvishoma nemaasidhi.Tungsten tsvimbo dzinogadzirwa kuburikidza nehupfu metallurgy kugadzira matekiniki.
Mhando dzeTungsten tsvimbo anowanzo kupatsanurwa kuita kwakachena tungsten tsvimbo, tungsten carbide tsvimbo, tungsten alloy tsvimbo, tungsten mhangura tsvimbo, tungsten conductor tsvimbo uye zvichingodaro.Kushandiswa kweTungsten Tsvimbo Tungsten tsvimbo inogona kushandiswa zvakanyanya mukuvhenekesa, maheater uye emagetsi mechininjiniya.Pamusoro pezvo, inogona kushandiswa kugadzira magetsi emagetsi, magirobhu emotokari uye tirakita, kugadzira matanda eparutivi, mafuremu, waya, maelectrodes, heaters uye zvinhu zvekuonana, PCB drills, drill bits, end mill uye zvichingodaro.
Zigong Xinhua Indasitiri yekupihwa ye tungsten tsvimbo inogona kugadzirwa mune zvisina mwero zvidimbu kana kucheka kune yaidiwa mutengi kureba mumadhayamita kubva pa 0.020 inches kusvika 0.750 inches.Kushivirira kudiki kunogona kutaurwa pakukumbira.Uye zvakare, matatu akasiyana epamusoro pekupedzisira kana epamusoro marapirwo anowanikwa zvichienderana nekwaunoda kupera kushandiswa.
