Kev sib piv ntawm cov hniav rauj tungsten carbide thiab cov hniav rauj ua los ntawm lwm cov ntaub ntawv

Piv nrog rau cov hlau manganese lossis cov hlau cuab yeej ib txwm muaj, tungsten carbide rauj muaj qhov zoo tseem ceeb hauv kev hnav tsis kam thiab kev pabcuam lub neej. Txawm hais tias cov hlau manganese lossis cov hlau cuab yeej kuj muaj qee qhov kev hnav tsis kam, tungsten carbide rauj zeb hniav muaj qhov nyuaj dua thiab muaj zog hnav tsis kam, tshwj xeeb tshaj yog thaum cuam tshuam nrog cov ntaub ntawv tawv.

Lub tshuab tsoo rauj siv rau kev tsoo cov khoom siv sib xyaw nrog cov khoom siv sib xyaw uas muaj zog tsawg dua 320 megapascals. Nws muaj qhov sib piv loj ntawm kev tsoo, yooj yim siv, hloov tau rau ntau hom khoom siv, thiab muaj zog tsoo, thiab siv tau ntau qhov chaw hauv kev siv cov khoom siv tsoo. Lub tshuab tsoo rauj siv rau kev tsoo ntau yam khoom siv tawg yooj yim thiab cov zaub mov, thiab tau siv dav hauv ntau yam lag luam xws li khoom siv hluav taws xob, tshuaj, khoom siv av nplaum, polycrystalline silicon, khoom siv dav hlau, iav kho qhov muag, roj teeb, roj teeb hmoov fluorescent peb lub hauv paus, lub zog tshiab, metallurgy, thee, ore, kev lag luam tshuaj lom neeg, cov khoom siv hauv tsev, geology, thiab lwm yam. Tsis tas li ntawd, lub tshuab tsoo tuaj yeem hloov qhov sib txawv ntawm cov neeg siv xav tau thiab kho qhov loj me ntawm cov khoom seem kom tau raws li cov kev xav tau sib txawv ntawm cov neeg siv tshuab tsoo sib txawv. Lub tshuab tsoo rauj feem ntau siv kev cuam tshuam los tsoo cov khoom siv. Cov txheej txheem tsoo yog raws li nram no: cov khoom siv nkag mus rau hauv lub tshuab tsoo thiab raug tsoo los ntawm kev cuam tshuam ntawm lub taub hau rauj tig ceev ceev. Cov khoom siv tsoo tau txais lub zog kinetic los ntawm lub taub hau rauj thiab maj mus rau lub baffle thiab sieve bar hauv lub thav duab ntawm kev ceev ceev. Tib lub sijhawm, cov khoom sib tsoo ua ke thiab raug tsoo ntau zaus. Cov khoom me dua qhov sib txawv ntawm cov tuav sieve raug tso tawm ntawm qhov sib txawv, thiab qee cov khoom loj dua raug tsoo dua los ntawm kev cuam tshuam, sib tsoo, thiab nias ntawm lub taub hau rauj ntawm lub tuav sieve. Cov khoom raug extruded los ntawm qhov sib txawv los ntawm lub taub hau rauj, yog li tau txais cov khoom me me uas xav tau.
