Kev piav qhia
Lub graphite electrode txiv mis yog ib qho me me tab sis tseem ceeb ntawm EAF steelmaking txheej txheem.Nws yog ib qho cylindrical-zoo li tus tivthaiv uas txuas cov electrode rau lub cub tawg.Thaum lub sij hawm steelmaking txheej txheem, cov electrode yog qis rau hauv lub cub tawg thiab muab tso rau hauv kev sib cuag nrog cov hlau molten.Cov hluav taws xob tam sim no ntws los ntawm electrode, ua kom muaj cua sov, uas ua rau cov hlau yaj hauv lub cub tawg.Lub txiv mis ua lub luag haujlwm tseem ceeb hauv kev tswj kom muaj kev ruaj ntseg hluav taws xob sib txuas ntawm electrode thiab qhov cub.

- Ua ntej zawm lub txiv mis, xyuas kom lub txiv mis nto huv si yam tsis muaj plua plav lossis qias neeg.(saib pic4)
Lub graphite electrode txiv mis yog ib qho tseem ceeb ntawm EAF steelmaking txheej txheem.Nws qhov zoo ncaj qha cuam tshuam rau kev ua tau zoo thiab kev ntseeg siab ntawm cov txheej txheem.Kev siv cov txiv mis zoo yog qhov tseem ceeb los tiv thaiv kev sib tsoo ntawm electrode thiab ua kom cov txheej txheem ua haujlwm zoo thiab ua haujlwm zoo.Raws li cov ntaub ntawv kev lag luam, ntau tshaj 80% ntawm electrode raug mob yog tshwm sim los ntawm cov txiv mis tawg thiab xoob tripping.Txhawm rau xaiv lub txiv mis kom zoo, cov hauv qab no yuav tsum tau txiav txim siab.
- Thermal conductivity
- Hluav taws xob resistivity
- Qhov ntom
- Mechanical zog
Thaum xaiv graphite electrode txiv mis, nws yog ib qho tseem ceeb uas yuav tau xav txog nws qhov zoo, qhov loj, thiab cov duab, thiab kev sib raug zoo nrog cov khoom siv hluav taws xob thiab qhov cub.Los ntawm kev xaiv lub txiv mis zoo, cov tuam ntxhab tuaj yeem txhim kho lawv cov hlau zoo thiab txo cov nqi cuam tshuam nrog kev poob qis thiab kev tsim khoom tsis zoo.
Xws li nws cov thermal conductivity, hluav taws xob resistivity, ntom, thiab txhua yam muaj zog.
