Ii-HP GRAPHITE ELECTRODES – Ububanzi buqala kwi-200 mm ukuya kwi-600 mm
Ii-HP GRAPHITE ELECTRODES – Ububanzi buqala kwi-200 mm ukuya kwi-600 mm
INKCAZELO
I-electrode yegrafiti yeHP yeyona nto iqhubayo yokwenza intsimbi kwizitofu zombane ze-arc. Yenziwe nge-petroleum coke, i-needle coke, i-coal pitch kwaye iveliswa luchungechunge lweenkqubo zokuvelisa ezingqongqo. Imigca yamandla aphezulu ingena nge-port ye-graphite electrode ngaphakathi komzimba wesithando. Oku kuya kukhupha amandla ombane kwisithando somlilo se-arc ukuze kufudunyezwe isithando somlilo.
Imfuno yee-electrode ezinkulu ezinobubanzi obuphezulu iye yanda njengoko ubukhulu be-EAF furnace bukhula. Ii-electrode ze-graphite ezinobubanzi obuyi-500 mm okanye i-600 mm ziye zathandwa kakhulu kwiminyaka yakutshanje.
