Kev thov dav
RP graphite electrode feem ntau siv hauv LF (Ladle furnace) thiab EAF (Electric Arc Rauv) steelmaking. Cov electrode yog sib xws nrog cov furnaces thiab muab cov txiaj ntsig zoo. RP graphite electrode kuj tseem siv rau hauv lwm daim ntawv thov xws li pre-ci anode thiab steel ladle.
Kev Taw Qhia Rau Tes Thiab Siv
1. Tshem tawm qhov kev tiv thaiv ntawm lub qhov tshiab electrode, xyuas seb cov xov hauv lub qhov electrode puas tiav thiab cov xov tsis tiav, hu rau cov kws tshaj lij engineers los txiav txim seb cov electrode puas tuaj yeem siv tau;
2.Screw lub electrode hanger rau hauv lub qhov electrode ntawm ib kawg, thiab tso lub cushion mos nyob rau hauv lwm kawg ntawm electrode kom tsis txhob ua puas lub electrode sib koom; (saib pic1)
3.Siv cua compressed los tshuab cov plua plav thiab sundries rau ntawm qhov chaw thiab lub qhov ntawm cov khoom siv hluav taws xob sib txuas, thiab tom qab ntawd ntxuav qhov chaw thiab qhov txuas ntawm cov electrode tshiab, ntxuav nws nrog txhuam; (saib pic2)
4. Nqa cov khoom siv hluav taws xob tshiab saum toj kawg nkaus ntawm qhov tseem tshuav electrode kom haum nrog lub qhov electrode thiab poob qeeb;
5.Siv tus nqi torque kom zoo xauv electrode; (saib pic3)
6.Clamp tuav yuav tsum tau muab tso tawm ntawm lub tswb kab. (saib pic4)
7.Nyob rau lub sij hawm refining, nws yog ib qho yooj yim uas yuav ua rau cov electrode nyias thiab ua rau tawg, sib koom ua ke poob, nce electrode noj, thov tsis txhob siv electrodes los tsa cov ntsiab lus carbon.
8.Dua rau cov khoom siv raw sib txawv siv los ntawm txhua lub chaw tsim khoom thiab cov txheej txheem tsim khoom, lub cev thiab tshuaj lom neeg ntawm electrodes thiab pob qij txha ntawm txhua lub chaw tsim khoom. Yog li hauv kev siv, nyob rau hauv cov xwm txheej dav dav, Thov tsis txhob sib xyaw siv electrodes thiab pob qij txha tsim los ntawm cov tuam txhab sib txawv.
