Powder metallurgy tungsten kazhinji ine tsanga yakanaka, iyo isina chinhu inowanzo sarudzwa nepamusoro tembiricha yekuforoma nekukunguruka nzira, tembiricha inowanzodzorwa pakati pe1500 ~ 1600 ℃.Mushure mekushaikwa, tungsten inogona kuwedzera kukungurutswa, kuumbwa kana kuruka.Iyo yekumanikidza machining inowanzoitwa pazasi recrystallization tembiricha, nekuti miganhu yezviyo ye recrystallized tungsten ine brittle, iyo inodzikamisa kushanda.Naizvozvo, nekuwedzera kwehuwandu hwekugadzirisa huwandu hwetungsten, tembiricha ye deformation inoderera zvinoenderana.
Tungsten plate rolling inogona kukamurwa kuita inopisa kukunguruka, inodziya kutenderera uye kutonhora kukunguruka.Nekuda kwekukura kukuru kwekupokana kwe tungsten, ma roller akajairika haakwanise kuzadzisa zvizere zvinodikanwa zvekutenderedza tungsten mahwendefa, nepo ma roller akagadzirwa nezvinhu zvakakosha anofanirwa kuiswa.Mukugadzirisa, ma rollers anofanirwa kuve akapisa, uye tembiricha yekupisa iri 100 ~ 350 ℃ zvichienderana neakasiyana ekukunguruka mamiriro.Mabhunga anogona kugadzirwa chete kana hukama hwehukama (chiyero cheiyo density chaiyo kune theoretical density) yakakwira kupfuura 90%, uye iine yakanaka processibility pahuwandu hwe92 ~ 94%.Iyo tungsten slab tembiricha ndeye 1,350 ~ 1,500 ℃ mukupisa kwekukungurutsira;kana deformation process parameters yakasarudzwa zvisina kunaka, blanks ichaiswa.Tembiricha yekutanga yekudziya inokunguruka i1,200 ℃;8mm-akakora anopisa akakungurutswa mahwendefa anogona kusvika paukobvu hwe0.5mm kuburikidza nekudziya kwekukunguruka.Tungsten mahwendefa akakwira mukupokana kwe deformation, uye muviri we roller unogona kukotamiswa uye kuremara mukukunguruka, saka mahwendefa anoumba husina yunifomu ukobvu pamwe nehupamhi hwegwara, uye anogona kuputika nekuda kwekusina-uniform deformation yezvose. zvikamu mu roller exchange kana rolling mill exchange process.The brittle-ductile transition tembiricha ye 0.5mm-gobvu mahwendefa ikamuri tembiricha kana yakakwirira kupfuura kamuri tembiricha;ne brittleness, mapepa anofanira kukungurutswa kuita 0.2mm-mashizha akakora patembiricha ye200 ~ 500 ℃.Munguva yekupedzisira yekukunguruka, tungsten mashizha matete uye akareba.Kuti ive nechokwadi chekudziya kwemaplateti, graphite kana molybdenum disulphide inowanzoputirwa, iyo isingangobatsiri kupisa mahwendefa asiwo ine mhedzisiro yekuzora mukuita machining.
