Chii chinonzi tungsten carbide?

Tungsten carbide, kana simende carbide, iyo inonziwo hard alloy, inozivikanwa seimwe yezvakaoma zvinhu.s munyika. Chaizvoizvo, isimbi, asi musanganiswaation tungsten, cobalt uye mamwe masimbi. Iyo yakanyanya kuomarara tungsten carbide yakagadzirwa izvozvi inosvika makumi mapfumbamwe nemana HRA, yakayerwa neRockwell A nzira. Imwe yezvakanyanya kukosha kuumbwas ye tungsten carbide ndeye tungsten, iyo ine yakanyanya kunyungudika pakati pesimbi dzese. Cobalt inoshanda sebhainda mune iyi simbi matrix uye inovandudzas simba rekukotama re tungsten carbide. Nekuda kwekuita kwepamusoro kwetungsten carbide, chinhu chakakwana kune akawanda maindasitiri, senge tungsten carbide inoisa, carbide rods uye kupera mill yeCNC yekucheka maturusi; kucheka mashizha ekucheka mapepa, kucheka makadhibhodi, nezvimwewo; tungsten carbide musoro unofa, chipikiri chinofa, kudhirowa kunofa nekuda kwekupfeka kuramba application; tungsten carbide saw tips, carbide plates, carbide strips yekucheka uye kupfeka kushandiswa; tungsten carbide mabhatani, HPGR studs, carbide migodhi inoisa yeminda yekuchera. Tungsten carbide zvinhu zvinoshandiswa zvakanyanya saka zvinodaidzwa zvakare“mazino kumaindasitiri”.

Ndeipi nzira yekugadzira tungsten carbide?

1. Nhanho yekutanga kugadzira tungsten carbide chigadzirwa, kugadzira hupfu. Hupfu kusanganiswa kweWC neCobalt, zvinosanganiswa pamwe chete mune imwe chiyero. Semuenzaniso, kana vatengi vachida tungsten carbide heading inofa, vanoda carbide giredhi YG20, huwandu 100 kilos. Ipapo mugadziri wehupfu anosanganisa 18kgs Cobalt hupfu ne80kgs WC poda, chiyero che2kgs mamwe masimbi ehupfu anozowedzerwa maererano nekambani yekubikira yegiredhi yeYG20. Hupfu hwese huchaiswa mumichina yekugaya. Kune hunyanzvi hwakasiyana hwemichina yekugaya, yakaita se5kgs yemasampuli, 25kgs, 50kgs, 100kgs, kana yakakura.

2. Mushure mekusanganiswa kwehupfu, danho rinotevera kupfapfaidza nekuomesa. MuZhuzhou Zvirinani Tungsten Carbide Kambani, shongwe yekupfapfaidza inoshandiswa, iyo inovandudza kuita kwemuviri uye kemikari kwetungsten carbide poda. Powder yakagadzirwa neSpray tower ine kuita kurinani kupfuura mamwe machina. Mushure mekupedza kuita uku, hupfu hwapinda“ready-to-press” mamiriro.

3. Iyo poda ichatsikirirwa mushure me“ready-to-press” hupfu inoedzwa OK. Kune nzira dzakasiyana dzekutsikirira, kana tinoti nzira dzakasiyana dzekugadzira tungsten carbide zvigadzirwa. Semuenzaniso, kana fekitori ikagadzira tungsten carbide saw tips, auto-press machine ichashandiswa; kana hombe tungsten carbide inofa ichidikanwa, hafu-manual yekutsikirira muchina uchashandiswa. Kune zvakare dzimwe nzira dzekugadzira tungsten carbide zvigadzirwa, sekutonhora isostatic kudzvanya (zita pfupi ndiCIP), uye extrusion michina.

4. Sintering ndiyo hurongwa mushure mekudzvanya, ihwowo muitiro wekupedzisira kugadzira tungsten carbide simbi iyo inogona kushandiswa seyakaomarara uye yakakwira simba reinjiniya simbi yekucheka, kupfeka-kuramba, kuchera, kana mamwe maapplication. Tembiricha ye sintering yakakwira kusvika 1400 centigrade. Pakuumbwa kwakasiyana, tembiricha ichava nemisiyano. Pakupisa kwakanyanya kudaro, binder inogona kusanganisa iyo WC poda uye kugadzira chimiro chakasimba. Iyo sintering process inogona kuitwa kana isina yakakwira isostatic gasi kumanikidza muchina (HIP).

Maitiro ari pamusoro apa tsananguro yakapusa yeiyo simende yekugadzira carbide maitiro. Kunyangwe zvinotaridzika zviri nyore, tungsten carbide kugadzirwa iindasitiri yemhando yepamusoro yekuunganidza. Hazvisi nyore kugadzira tungsten carbide zvigadzirwa. Tungsten imhando yeasinga gadziriswe sosi, kana yangoshandiswa, hazvigoneke kuumba zvakare munguva pfupi. Koshesa sosi yakakosha, ita shuwa kuti batch yega yega tungsten carbide zvigadzirwa inokodzera isati yasvika mumaoko evatengi, ndicho chimwe chezvikonzero zvakakosha zvinotisundidzira kuita zvirinani. Ramba uchifamba, ramba uchivandudza!
