Cov txheej txheem tseem ceeb cuam tshuam rau iav melting

Cov txheej txheem tseem ceeb uas cuam tshuam rau iav melting txuas ntxiv dhau ntawm theem me me, raws li lawv tau siv roj rauv, cua txias, thiab kev xaiv ntawm cov neeg sawv cev. Hauv qab no yog cov ncauj lus kom ntxaws ntawm cov ntsiab lus:

ⅠCov. Khoom Siv Raw Npaj Npaj Thiab Tswjhwm Zoo

1. Tshuaj lom neeg sib xyaw ua ke

Sio₂ thiab Refractory tebchaw: al₂o₃ ntawm sio₂, al₂o₃, zro₂, thiab lwm yam tebchaw ncaj qha cuam tshuam ncaj qha melting tus nqi. Cov ntsiab lus siab dua nce qhov yuav tsum tau melting kub thiab siv hluav taws xob.

Alkali hlau hlau oxides (piv txwv li, Naiso, Lako): txo qis melting kub. Liio, vim nws cov hluav taws xob me thiab hluav taws xob me thiab muaj siab electronegativity, yog qhov tshwj xeeb thiab tuaj yeem txhim kho lub zog lub cev ntawm iav.

2. Batch ua ntej

Ya noo tswj:

Qhov zoo tshaj plaws noo noo (3% ~ 5%): txhim kho cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv, txo cov plua plav thiab cais;

Ntau ntau noo noo: ua rau hnyav hnyav uas tsis raug thiab lub sijhawm ntev.

Particle loj faib:

Kev ntsuas coarse heev: txo cov khoom siv tiv thaiv kev sib cuag thaj tsam, sijhawm ntev melting;

Ntau qhov zoo tshaj plaws hais: ua rau agglomeration thiab electrostatic adsorption, tabking uniform melting.

3. Cullet tswj

Cullet yuav tsum yog huv, tsis muaj kev huv huv, thiab phim cov particle me me ntawm cov ntaub ntawv raw tam sim no kom tsis txhob qhia cov npuas lossis cov khoom seem.

Ⅱ. Tsim Qauvthiab roj cov khoom

1. Refractory Cov Khoom Siv

Kev kub siab rau qhov kub thiab txias zirconium corundum cib pob zeb, yog li yuav tsum tau txo cov kab mob pob zeb los ntawm kev yaig thiab scouring.

Thermal stability: tiv thaiv kev kub ntxhov hloov dua thiab zam kev siv recdactory vim yog thermal poob siab.

2. Roj thiab sib txuas ua ke

Roj Calorific tus nqi thiab kev sib txuas lus (oxidizing / txo) yuav tsum phim cov iav muaj pes tsawg leeg. Piv txwv li:

Cov roj nkev / cov roj hnyav: yuav tsum tau ua kom haum huab cua-roj sib piv kom tsis txhob muaj cov khoom seem sulph;

Hluav taws xob melting: haum rau high-precision melting (piv txwv li,Kho Qhov Muag Iav) Tab sis noj ntau zog.

ⅢCov. Melting Txheej Txheem Parameter Optimization

1. Tswj Kub

Melting kub (1450 ~ 1500 ℃) Tuaj yeem nce qhov kub yaj tuaj yeem tsa cov nqi melting los ntawm 1%, tab sis Refractory yaig ob npaug. Qhov sib npaug ntawm kev ua tau zoo thiab cov khoom siv li siv lub neej yog qhov tsim nyog.

Qhov ntsuas kub: Kev tswj kom kub: Kev tswj cov cub tawg hauv cov chaw ua kom sib txawv (melting, fining, cua txias) yog qhov tseem ceeb kom tsis txhob muaj cov nyob hauv zos overheating.

2. Huab cua thiab siab

Oxidizing huab cua: Txhawb nqa cov organic decomposition tab sis yuav ua kom muaj kev sib zog ua cov oxidide;

Txo cov cua: Forgpresses Fe³ + xim (rau iav tsis muaj xim) tab sis yuav tsum zam kom zam cov pa roj carbon;

Cub taws siab ruaj khov: me ntsis kev ua kom zoo (+ 2 teev) tiv thaiv cov cua txias thiab ua kom muaj kev tshem tawm npuas.

3.Qhov chaw sawv cev thiab fluxes

Cov tshuaj fluoride (piv txwv li, caf₂): txo qis melt viscosity thiab nrawm ntawm kev tshem tawm npuas noo;

Nitrates (piv txwv li, nano₃): tso oxygen los txhawb okidative sib;

Composite fluxes **: Xws li, dag li caug + Nayco₃, synergistically qis melting kub.

ⅣCov. Kev saib xyuas tsis muaj zog ntawm cov txheej txheem melting

1. Melt viscosity thiab fluidity

Kev tshuaj xyuas lub sijhawm tiag tiag siv cov neeg tuaj saib qhib kev sib hloov lossis cov tshuaj lom zem rau kev ua kom zoo tshaj plaws.

2. Kev tshem tawm npuas tshem tawm

Soj ntsuam ntawm npuas faib khoom siv X-Ray lossis cov tswv yim ua kom pom kev zoo rau cov neeg sawv cev ua kom zoo thiab ua kom tiav.

ⅤCov. Cov teeb meem tshwm sim thiab cov tswv yim txhim kho

Tag

Iav melting yog qhov tshwm sim ntawm cov synergy ntawm cov khoom siv raw, khoom siv, thiab cov txheej txheem tsis sib xws. Nws yuav tsum tau ceevfully kev tswj ntawm tshuaj lom neeg tsim qauv, particle loj optimization, refractory khoom hloov kho dua tshiab, thiab cov txheej txheem dynamic parameter tswj. Los ntawm kev tshawb fawb tau hloov kho fluxes, stabilizing yaj melting ib puag ncig (kub / siab hloov kho, thaum lub zog ua tau zoo, thaum lub zog kev siv thiab cov nqi tsim tawm tsawg.
