Kev Qhia Tes Thiab Siv Rau Graphite Electrodes
1.Siv cov cuab yeej nqa tshwj xeeb rau lub neej ntawm graphite electrode kom tsis txhob puas thaum lub sijhawm thauj mus los.(saib pic1)
2. Graphite electrode yuav tsum tau khaws cia kom deb ntawm kev ntub dej lossis ntub los ntawm nag, daus, khaws cia qhuav.(saib pic2)
3. Ua tib zoo xyuas ua ntej siv kom paub tseeb tias lub qhov (socket) thiab lub txiv mis xov yog tsim nyog rau kev siv, nrog rau kev tshuaj xyuas rau lub suab, ntsaws.(saib pic3)
4. Ntxuav lub txiv mis thiab lub qhov (socket) xov los ntawm cua compressed.(saib pic4)
5. Ua ntej siv, cov graphite electrode yuav tsum tau qhuav nyob rau hauv lub cub tawg, lub ziab kub yuav tsum tsawg tshaj li 150 ℃, lub sij hawm qhuav yuav tsum ntau tshaj 30 teev.(saib pic5)
6.Graphite electrode yuav tsum tau txuas nrog nruj nreem thiab ncaj nraim nrog haum nruj torque.(saib pic6)
7. Kom tsis txhob graphite electrode breakage, muab qhov loj nyob rau hauv qis txoj hauj lwm thiab me me nyob rau hauv lub Upper txoj hauj lwm.
