Kev siv tshuab ntawm Graphite Electrodes

1. Xaus kev noj haus

Xws li sublimation ntawm cov khoom siv graphite tshwm sim los ntawm qhov kub thiab txias ntawm arc thiab poob ntawm cov tshuaj tiv thaiv ntawm electrode kawg thiab cov hlau molten thiab slag. Nws kuj tseem cuam tshuam txog seb cov electrode tau muab tso rau hauv cov hlau molten kom cov pa roj carbon ntau ntxiv. Lub siab kub sublimation tus nqi ntawm qhov kawg yog tsuas yog txiav txim los ntawm qhov tam sim no ceev los ntawm electrode, thiab thib ob yog hais txog lub cheeb ntawm sab ntawm lub electrode tom qab oxidation.

2, sab oxidation

Tus nqi ntawm oxidation nyob rau sab ntawm lub electrode muaj feem xyuam rau chav tsev oxidation tus nqi thiab qhov chaw raug. Feem ntau, tus nqi ntawm oxidation nyob rau sab ntawm lub electrode account txog li 50% ntawm tag nrho cov kev siv ntawm electrode. Nyob rau xyoo tas los no, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws, nws muaj peev xwm ua kom lub smelting ceev ntawm lub tshuab hluav taws xob, qhov kev ua haujlwm ntawm cov pa oxygen tshuab tau nce ntxiv, uas ua rau muaj kev nce hauv oxidation poob ntawm electrode.

3. Poob poob

Thaum cov electrode txuas ntxiv mus rau kev sib txuas ntawm sab sauv thiab qis electrodes, ib feem me me ntawm cov electrode los yog kev sib koom ua ke (xws li cov residue) yuav raug sib cais vim yog oxidation ntawm lub cev thiab kev nkag mus ntawm qhov tawg.

4, electrode tawg

Xws li tawg electrode torso thiab cov pob qij txha tawg. Qhov tawg ntawm cov electrode yog cuam tshuam nrog kev ua haujlwm zoo thiab kev koom tes ntawm graphite electrode thiab kev sib koom ua ke, thiab tseem muaj feem xyuam rau kev ua haujlwm steel.

5, qhov saum npoo peels tawm thiab blocks tawm

Nyob rau hauv tus txheej txheem ntawm smelting, qhov tshwm sim yog hais tias tus electrode' tus kheej thermal shock kuj tsis zoo vim lub ceev ceev txias thiab cua sov.
