I-tungsten yomgubo we-metallurgy idla ngokuba nenkozo entle, into engenanto ikhethwa ngokubanzi ngobushushu obuphezulu bokubumba kunye nendlela yokuqengqeleka, ubushushu bulawulwa ngokubanzi phakathi kwe-1500 ~ 1600 ℃.Emva kokungenanto, i-tungsten inokugqithwa ngakumbi, ifakwe okanye iphonswe.I-machining yoxinzelelo idla ngokuqhutyelwa ngaphantsi kweqondo lokushisa le-recrystallization, kuba imida yeenkozo ze-tungsten ehlaziyiweyo i-brittle, ekhawulela ukusebenza.Ngoko ke, ngokunyuka kwenani elipheleleyo lokucubungula i-tungsten, ukushisa kwe-deformation kunciphisa ngokuhambelanayo.
Ukuqengqeleka kwepleyiti yeTungsten kunokohlulwa ibe kukuqengqeleka okushushu, ukuqengqeleka okufudumeleyo kunye nokuqengqeleka okubandayo.Ngenxa yokuxhatshazwa okukhulu kwe-deformation ye-tungsten, ii-roller eziqhelekileyo azikwazi ukuhlangabezana ngokupheleleyo neemfuno ze-rolling tungsten plates, ngelixa ii-roller ezenziwe ngezinto ezikhethekileyo kufuneka zisetyenziswe.Kwinkqubo yokuqengqeleka, i-roller kufuneka ifakwe ngaphambili, kwaye i-preheating ye-preheating yi-100 ~ 350 ℃ ngokwemiqathango eyahlukeneyo yokuqengqeleka.Ii-blanks zingenziwa ngoomatshini kuphela xa ukuxinana okuzalanayo (umlinganiselo woxinaniso oluyinyani ukuya kuxinaniso lwethiyori) lungaphezulu kwama-90%, kwaye lunokuqhubekeka kakuhle kuxinaniso lwe-92 ~ 94%.Ubushushu be-tungsten slab yi-1,350 ~ 1,500 ℃ kwinkqubo eshushu yokuqengqeleka;ukuba iiparamitha zenkqubo yokuguqulwa zikhethwe ngendlela engafanelekanga, izikhewu ziya kwahlulwa.Iqondo lobushushu lokuqala lokuqengqeleka kobushushu yi-1,200℃;Iipleyiti ezigoqiweyo eziyi-8mm ezishushu zinokufikelela kubukhulu obuyi-0.5mm ngokuqengqeleka okufudumeleyo.Iipleyiti ze-Tungsten ziphezulu ekuchaseni ukuguqulwa, kwaye umzimba we-roller unokugoba kwaye ukhubazeke kwinkqubo yokuqengqeleka, ngoko ke iipleyiti ziya kwenza ubukhulu obungafaniyo ecaleni kobubanzi, kwaye zinokuqhekeka ngenxa yokuguqulwa okungafanelanga konke. iinxalenye kwi-roller exchange okanye inkqubo yokutshintshiselana ye-rolling.Ukushisa kwe-brittle-ductile transition ye-0.5mm-thick plates yiqondo lokushisa kwegumbi okanye liphezulu kuneqondo lokushisa;kunye brittleness, amaphepha kufuneka iqengqeleke zibe 0.2mm-shick sheets kwiqondo lobushushu 200 ~ 500℃.Kwixesha elizayo lokuqengqeleka, amaphepha e-tungsten ancinci kwaye ade.Ukuqinisekisa ukufudumeza okufanayo kweepleyiti, igraphite okanye i-molybdenum disulphide idla ngokugqunywa, engeyiyo kuphela inzuzo yokufudumeza amacwecwe kodwa inefuthe lokuthambisa kwinkqubo yomatshini.
