Tungsten Hlau Khoom Hom

Cov txheej txheem Sintering siv tau qhib hluav taws xob hluav taws xob uas tuaj yeem txav mus rau hauv cov kab ke thiab tuaj yeem cuam tshuam rau sab saum toj ntawm cov vaj tse, siv pa roj carbon. Ib qho sib xyaw ua hluav taws xob muaj cov tungsten coke (bitumen coke (lossis cov hlau ua kom pom tseeb) thiab qis qis qis dua qhov ua kom tawv me me. Tom qab sau, lub cub tawg nres lub cub tawg, rub tawm lub rauv lub cev, tshem tawm lub rauv lub cev, tshem tawm lub rauv sab sauv ntawm lub zog cua sov thiab condenses cov curds. Tom qab ntawd clots raug tshem tawm, tsoo thiab ntxuav; Tshem cov npoo, slag thiab tsis tsim nyog qhov chaw rov qab mus rau lub cub tawg rau kev thim rov qab. Cov khoom muaj li 80% tungsten thiab tsis pub ntau tshaj 1% carbon.
Kev xaiv cov hlau yog qhov haum rau smelting tungsten hlau muaj 70% tungsten nrog lub taw tes me me. Kev siv cov silicon thiab carbon li txo cov neeg sawv cev; Kev txo nqi them (tseem hu ua kev sib thooj zoo), ua kom zoo dua qub, cov hlau rov qab hauv peb theem. Hauv kev txo qis theem, cov khoom siv hluav taws xob ua rau muaj ntau dua 10% kev tshem tawm cov hlau los ntawm kev ua kom zoo nkauj (los yog smelt Tom qab ntawd txav mus rau theem ua kom huv si, thaum lub sijhawm no tungsten mloog zoo, ua haujlwm tsis zoo xws li silicon thiab manganese ntawm qhov kub siab dua. Kev ua piv txwv rau kev sim, tom qab txiav txim siab txog kev sib xws ntawm cov ntawv sib xyaw, sau los ntawm cov hlau pib. Yav dhau los, cov hlau diav tau siv rau cov hlau tawm ntawm cov hlau rau hauv lub pas dej, cov Jilin Ferrroalloy cog mus rau cov khoom siv hlau rho tawm cov khoom ua haujlwm. Thaum lub sij hawm lub sij hawm ntawm cov hlau rho tawm, - tseem raws li lub cub tawg, asphalt coke tau muab ntxiv. Kev siv hluav taws xob thaum lub sijhawm smelting yog li 3000 kWh / t, thiab tus nqi tè yog li 99%.
Aluminium -} kev siv cov khib nyiab rau kev siv khib nyiab tungsten cobalt Cobalt CARBALTION TOM QAB ROV QAB TUGTENCTENY. Tsim txhuas -}} thungsten thiab hlau thermal zog, yog li cov pa roj raw, yog li cov pa roj rucksten, tuaj yeem txuag tau hluav taws xob ntau thiab txo cov nqi. Nyob rau tib lub sijhawm, txij li cov impurities nyob rau hauv raw tungsten carbide yog ntau dua li cov khoom zoo tshaj qhov zoo tshaj li tungsten hlau raws li tungsten mloog. Tus lej tungsten Rov qab tus nqi kuj tseem siab dua nyob rau hauv tus txheej txheem uas siv tungsten mloog.
Tungsten yog kim, cov txheej txheem ntau lawm yuav tsum tau them cov khoom siv rov qab los ua kom muaj qhov cub tawg, cov hluav taws xob hluav taws xob yuav tsum yog cov hluav taws xob hluav taws xob, lub tshuab ua kom huv si, tungsten plua plav rov qab.
