tungsten steel khoom muaj li ntawm 18% tungsten, tungsten steel belongs rau cemented carbide, kuj hu ua tungsten-titanium alloy.Lub hardness yog 10K ntawm Vickers nplai, thib ob tsuas yog pob zeb diamond.Vim li no, tungsten steel khoom, muaj tus yam ntxwv ntawm tsis yooj yim rau hnav.Cov khoom siv tungsten carbide feem ntau yog siv rau hauv cov cuab yeej tshuab dhos, cuam tshuam cov khoom siv, iav cutter khoom, pobzeb cutters, nyuaj, tsis ntshai annealing, tab sis nkig.Nws yog ib qho tsis tshua muaj hlau.
Tungsten carbide sintering pwm:
Tungsten carbide sintering molding yog nias cov hmoov rau hauv cov khoom siv, thiab tom qab ntawd mus rau hauv lub qhov cub sintering rhuab mus rau qhov kub thiab txias 〔 sintering kub 〕, thiab khaws cia rau qee lub sijhawm (lub sijhawm txuag hluav taws xob), thiab tom qab ntawd txias nws, thiaj li tau txais cov khoom siv tungsten steel nrog rau qhov yuav tsum tau ua.
Cov txheej txheem tungsten carbide sintering tuaj yeem muab faib ua plaub theem:
1: Kev tshem tawm ntawm tus neeg sawv cev tsim, sintering lub sijhawm pib nrog qhov kub thiab txias, tus neeg sawv cev tsim maj mam decomposed los yog vaporised, tshem tawm los ntawm lub cev sintered, tib lub sijhawm, tus neeg sawv cev tsim ntau dua los yog tsawg dua rau lub cev sintered. cov pa roj carbon ntau ntxiv, cov pa roj carbon monoxide nce yuav nrog hom kev tsim tus neeg sawv cev, tus naj npawb ntawm cov txheej txheem sintering thiab qhov sib txawv thiab hloov.
Cov hmoov av oxides raug txo qis, nyob rau hauv qhov kub thiab txias, hydrogen tuaj yeem txo qis cobalt thiab tungsten oxides, yog tias lub tshuab nqus tsev tshem tawm ntawm kev tsim tus neeg sawv cev thiab sintering, carbon thiab oxygen cov tshuaj tiv thaiv tsis muaj zog.Cov hmoov hmoov nug qhov kev sib cuag kev ntxhov siab yog maj mam tshem tawm, cov hmoov hlau sib txuas tau pib tsim cov khoom rov qab thiab rov tsim cov khoom lag luam, qhov chaw diffusion pib tshwm sim, lub zog briquette tau txhim kho.
2: Khoom theem sintering theem (800 ° c - eutectic kub)
Nyob rau ntawm qhov kub thiab txias ua ntej qhov tshwm sim ntawm cov kua theem, ntxiv rau kev txuas ntxiv cov txheej txheem uas tshwm sim nyob rau hauv lub dhau los theem, cov tshuaj tiv thaiv-theem thiab diffusion intensifies, yas ntws yog txhim khu kev qha, thiab lub sintered lub cev zoo nkaus li ntsws.
3: Ua kua theem sintering theem (eutectic kub - sintering kub>)
Thaum cov kua theem tshwm nyob rau hauv lub sintered lub cev, lub contraction yog ua tiav sai heev, ua raws li los ntawm ib tug crystalline hloov mus rau lub hauv paus lub koom haum thiab cov qauv ntawm cov alloy.
4: Theem cua txias (Sintering Temperature - Chav Kub>)
Nyob rau theem no, lub koom haum thiab theem muaj pes tsawg leeg ntawm tungsten steel nrog qhov sib txawv txias txias thiab tsim qee qhov kev hloov pauv, koj tuaj yeem siv cov yam ntxwv no, kev kho cua sov ntawm tungsten steel los txhim kho nws lub cev thiab cov khoom siv kho tshuab.
Tungsten rods yog puag ncig lossis square tungsten khoom.Tungsten yog ib qho nyuaj, tuab hlau nrog qhov kub siab tshaj plaws ntawm cov hlau: 6,192 ° F (3,422 ° C).Nws yog cov khoom siv tshuaj lom neeg nrog atomic tooj 74. Nws yog cov khoom siv tshuaj lom neeg nrog tus lej atomic ntawm 74. tungsten muaj kev tiv thaiv corrosion zoo heev thiab tsis tshua muaj kev cuam tshuam los ntawm acids.Tungsten rods yog tsim los ntawm cov hmoov hlau metallurgy cov txheej txheem.
Hom Tungsten Rods Feem ntau muab faib ua cov tungsten ntshiab, tungsten carbide rods, tungsten alloy rods, tungsten tooj liab rods, tungsten conductor rods thiab hais txog.Daim ntawv thov ntawm Tungsten Rods Tungsten rods tuaj yeem siv dav hauv teeb pom kev zoo, cua sov thiab hluav taws xob mechanical engineering.Tsis tas li ntawd, nws tuaj yeem siv los tsim hluav taws xob teeb pom kev zoo, tsheb thiab tsheb laij teb qhov muag teev, ua lattice sab rods, thav ntawv, xov hlau, electrodes, cua sov thiab cov ntaub ntawv tiv tauj, PCB laum, laum khoom, kawg mills thiab lwm yam.
Zigong Xinhua Muaj cov khoom siv ntawm tungsten rods tuaj yeem tsim nyob rau hauv qhov ntev ntev los yog txiav rau cov neeg siv khoom xav tau qhov ntev ntawm txoj kab uas hla ntawm 0.020 ntiv mus rau 0.750 ntiv tes.Kev kam rau me me tuaj yeem hais tau raws li qhov kev thov.Tsis tas li ntawd, peb qhov sib txawv ntawm qhov chaw tiav lossis kev kho deg muaj nyob ntawm qhov xav tau siv kawg.
