Dab tsi yog qhov tseem ceeb uas cuam tshuam rau graphite electrode noj hauv hluav taws xob arc rauv steelmaking?

Cov yam tseem ceeb muaj xws li: (1) Tus nqi them thiab txoj kev them nqi. (2) Lub sijhawm them nyiaj thiab lub sijhawm fais fab tuag. (3) Smelting voj voog. (4) Cov pa paug pov tseg thiab cov plua plav tshem tawm. (5) Electrode hloov zoo. (6) Load kho kom zoo. (7) Oxygen tshuab ua haujlwm. (8) Electrode kev twb kev txuas zoo. (9) Electrode sib koom ua ke lub cev zoo. (10) Electrode qhov sib koom ua ke thiab kev sib koom ua haujlwm raug.

Dab tsi yuav tsum tau them sai sai rau hauv kev cia ntawm graphite electrodes hauv cov nroj tsuag steel?
Cov hluav taws xob thiab cov pob qij txha yuav tsum tau muab khaws cia rau hauv cov cement hauv pem teb kom huv si kom tiv thaiv cov electrodes los ntawm kev puas tsuaj los yog daig nrog av nkos. Rau cov electrodes uas tsis siv nyob rau ib ntus, tsis txhob tshem tawm cov ntim los tiv thaiv cov plua plav thiab cov khib nyiab los ntawm kev poob ntawm cov xov sib txuas lossis cov electrode kawg nto thiab cov xov sab hauv ntawm lub qhov electrode. Electrodes yuav tsum tau muab tso rau hauv lub warehouse kom huv si, thiab ob qhov kawg ntawm cov electrode pawg yuav tsum tau padded los tiv thaiv cov pawg los ntawm slipping. Lub stacking qhov siab ntawm cov electrodes feem ntau yuav tsum tsis pub tshaj ob meters. Cov electrodes yuav tsum tau muab cia rau hauv cov nag thiab noo noo-pov thawj kom tiv thaiv cov kab nrib pleb thiab nrawm oxidation thaum lub sij hawm steelmaking. Cov pob qij txha electrode yuav tsum tsis txhob muab khaws cia ze rau qhov kub siab los tiv thaiv cov pob qij txha los ntawm melting thiab overflowing.

Yuav ua li cas kom tsis txhob electrode breakage thiab tripping thaum lub sij hawm steelmaking?
Cov kev ntsuas hauv qab no tuaj yeem tiv thaiv electrode breakage thiab tripping thaum lub sij hawm steelmaking: (1) Cov theem ntawm electrode yog raug thiab counterclockwise. (2) Cov seem hlau hauv lub cub tawg yog sib npaug, thiab cov khoom seem ntawm cov hlau loj tau muab tso rau hauv qab ntawm lub qhov cub kom ntau li ntau tau. (3) Tsis txhob muaj cov khoom siv tsis zoo hauv cov khoom siv hlau. (4) Cov kab hluav taws xob yog ua raws li lub qhov cub sab saum toj thiab cov kab hluav taws xob yog sib npaug. Lub qhov cub sab saum toj ntawm lub qhov phab ntsa yuav tsum tau ntxuav tas li kom tsis txhob muaj cov slag seem thiab tawg cov electrode. (5) Khaws lub qhov cub hluav taws xob tilting qhov system kom zoo kom lub tshuab hluav taws xob tilting ruaj khov. (6) Tsis txhob clamping lub electrode tuav ntawm electrode kev twb kev txuas thiab lub electrode sib koom lub qhov. (7) Xaiv lub zog siab, siab-precision thiab cov pob qij txha zoo. (8) Lub torque siv thaum txuas cov electrodes yuav tsum tsim nyog. (9) Ua ntej thiab thaum lub sij hawm kev sib txuas ntawm electrode, tiv thaiv kev puas tsuaj rau lub electrode qhov xov thiab cov xov sib txuas. (10) Tiv thaiv steel slag los yog txawv teb chaws teeb meem los ntawm embedded nyob rau hauv lub electrode qhov thiab qhov sib koom ua ke los cuam tshuam cov ntsia hlau txuas.

Yuav ua li cas steel mills yuav tsum xyuam xim rau thaum lub sij hawm crane hoisting thaum siv graphite electrodes?
Txawm hais tias siv lub forklift lossis crane thauj cov electrode, nws yuav tsum tau ua tib zoo ua haujlwm. Thaum lub sij hawm electrode hoisting txheej txheem, kev puas tsuaj rau lub electrode kawg thiab xov yuav ua rau muaj teeb meem loj rau kev siv cov electrode. Tshwj xeeb, cov xov ntawm lub qhov threaded thiab qhov sib koom ua ke yuav tsum tau tiv thaiv. Thaum nqa cov electrode, yuav tsum muaj cov ntaub thaiv npog tiv thaiv kom tsis txhob ua rau lub ntsej muag electrode kawg thiab cov xov sib txuas.

Yuav ua li cas txuas cov electrode kom raug?
Thaum sib txuas, siv cov cua compressed los tshuab ntxuav lub qhov electrode, lub ntsej muag electrode thiab qhov sib koom ua ke. Yuav tsum tsis txhob muaj plua plav thiab cov khoom txawv teb chaws embedded. Kev sib txuas yuav tsum tau ua kom huv si thiab tiaj tus. Thaum ob lub electrodes raug ntsia rau hauv ib qho twg (qhov sib txawv yog li 10mm), tshuab lawv dua nrog cov cua compressed, thiab tom qab ntawd muab cov electrode kom nruj nrog lub torque clamp. Lub torque siv thaum lub sij hawm nruj yuav tsum tsim nyog. Yog tias pom qhov sib txawv ntawm qhov kev sib txuas tom qab nruj, nws yuav tsum tau muab tshem tawm thiab rov txuas dua kom txog thaum tsis muaj qhov sib txawv.
