Graphite rotor rau txhuas casting

Khoom Taw Qhia:

Tus txheej txheem ua hauj lwm ntawm aGraphite rotoryog tias qhov rotrating rotor tsoo cov nitrogen (lossis argon) tshuab ua kom muaj cov npuas loj thiab tawg rau hauv cov hlau molten. Npuas nyob rau hauv lub txiv ntseej nqus helogen los ntawm cov txiv ntseej thiab yog ib nrab ntawm cov roj av, thiab nqa cov kua muag kom huv. Vim yog cov kev tawg ntawm npuas, lawv tov tusyees nrog kev tig yaj thiab maj mam ntab rau hauv ib qho kauv. Lawv muaj lub sijhawm sib cuag tau ntev nrog cov yaj thiab tsis ua rau cov phom sij hydrogen los ntawm cov teeb meem hydrogen los ntawm txhuas alten thiab cuam tshuam kev txhim kho cov txiaj ntsig ua kom huv.

Cov nta ntawm graphite rotor khoom:

1. Daim duab graphite rotor rotating nozzle yog ua los ntawm cov kev ntshiab-purity graphite. 2. Tom qab kev kho deg, lub neej pabcuam yog hais txog peb zaug ntawm cov khoom lag luam zoo li qub, thiab nws yog dav siv nyob rau hauv aluminium alloy casting kev lag luam.

Hais txog graphite rotor kev lag luam:

Rau txhuas alloy foundries thiab txhuas cov khoom lag luam khoom, nws yog ib qho tseem ceeb kom txo tus nqi. Hauv qhov no, cov ntsiab lus graphite tsim los ntawm peb lub tuam txhab tuaj yeem nqa cov txiaj ntsig hauv qab no:

1. Tiv Thaiv Cov Nqi

2. Txo kev noj ntawm cov roj inert

3. Txo cov ntsiab lus aluminium hauv slag

4. Txo cov nqi ua haujlwm

5. Kev ua tau zoo, siv sijhawm dua hloov mus

6. Txhim kho kev cia siab thiab txo tus nqi kho.

Tsim thiab xaj ntawm graphite rotors:

Vim yog cov kev sib txawv ntawm cov ntsiab lus tshwj xeeb ntawm cov rotors uas siv rau txhua qhov cam khwb cia lossis cov kab ntau lawm. Firstly, cov neeg yuav khoom yuav muab cov duab kos thawj thiab cov ntawv tshawb fawb ntxiv rau ntawm chaw ib puag ncig kev tshawb fawb ib puag ncig. Tom qab ntawd, raws li cov duab kos, kev tshawb xyuas kev sib txuas ua ke sib txuas, thiab ib qib kev sib hloov ntawm cov graphite rotor, thiab ib qho kev kho kom haum anti erosion npaj yuav tau npaj siab.

Cov duab graphite rotor rotating nozzle yog ua los ntawm cov kab ke siab-huv. Ntxiv rau kev txiav txim siab qhov yuav tsum tau muab npuas tawm, ua kom muaj cov roj centerring rau tusyees nrog cov roj centering thiab cov kua txhuas ua kua, thiab txhim kho cov degregassing thiab purification nyhuv. Qhov ceev ntawm cov rotor graphite tuaj yeem hloov kho steplessly los ntawm zaus converter kev tswj hwm kev hloov ceev, mus txog li 700? R / min. Qhov tshwj xeeb ntawm graphite rotor yog φ 70mm ~ 250mm, nrog impeller specite muaj lub zog siab, thiab Aluminium Flow corrosion. Thaum lub sij hawm ua kom huv si thiab degassing, nitrogen tau qhia rau kev tiv thaiv cov kua roj hauv cov rotor thiab txuas ntxiv nws txoj kev pabcuam lub neej. Tus neeg tsis sib haum xeeb yog streamlined, uas tuaj yeem txo qhov tsis kam thaum lub sij hawm sib tov, thiab yaig quab yuam tau tsim los ntawm impeller thiab aluminium alloy kua kuj tseem me. Qhov no ua rau tus nqi degassing ntawm ntau tshaj 50%, luv luv lub sijhawm SMELTING, thiab txo cov nqi ntau lawm.
