Detail Produk
Elektroda nggawa listrik sing dadi panas tungku busur listrik, sing paling akeh tungku baja. Iki digawe saka coke petroleum sawise dicampur karo pitch petroleum, diekstrusi lan dibentuk, banjur dipanggang kanggo sinter, lan banjur digrafit kanthi panas ing ndhuwur suhu (3000 ° C) sing ngowahi karbon dadi grafit. Padha bisa beda-beda ing ukuran nganti 11 ft. dawa lan 30 ing diameteripun.
Panganggone
- 01 Proporsi baja global sing tambah akeh digawe nggunakake tungku busur listrik
- 02 Tungku busur listrik dhewe dadi luwih efisien lan nggawe luwih akeh baja saben ton elektroda
