Electrode RP Graphite airson Fùirneis Ladle
Seòrsachadh electrodes graphite
Dh’ fhaodadh fùirneis dèanamh stàilinn arc dealain a bhith air a roinn ann an fhùirneis dealain cumhachd cunbhalach (timcheall air 300KVA gach tunna), fùirneis dealain àrd-chumhachd (timcheall air 400kVA gach tunna) agus fùirneis dealain ultra-chumhachd (500 ~ 1200KV / A gach tunna) a rèir comas cruth-atharrachaidh gach tunna de chomas fùirneis.
A rèir seòrsachadh ìre cumhachd dealain dèanamh stàilinn fùirneis dealain, agus a rèir na h-eadar-dhealachaidhean de stuthan amh a thathas a ’cleachdadh ann an cinneasachadh electrode agus clàran-amais corporra is ceimigeach de electrod crìochnaichte, tha electrod grafait air a roinn ann an trì seòrsaichean: dealan grafait cumhachd cunbhalach (RP). , dealan grafait cumhachd àrd (HP) agus dealan grafait cumhachd ultra-àrd (UHP).
Ro-ràdh RP Graphite Electrode
Tha dealan grafait RP air a dhèanamh sa mhòr-chuid de chòc peatrail mar stuthan amh agus asphalt guail mar inneal-ceangail tro calcination, batching, glùinean, cumadh, bèicearachd, grafitization agus innealachadh.
Is e stiùiriche a th’ ann an Graphite Electrode a bhios a ’leigeil a-mach lùth dealain anns an fhùirneis arc dealain gus an sgudal stàilinn a theasachadh agus a leaghadh.
Feartan
Tha dealan grafait RP air a thoirt a-mach le còc peatrail, le teòthachd grafitization ìosal.tha na feartan a leanas aige:
1.High resistivity
2.Large loidhneach leudachaidh coefficient
3.Poor tearmach clisgeadh an aghaidh
4.Tha an dùmhlachd gnàthach ceadaichte ìosal
Cleachdadh RP Graphite Electrode
(1) Airson dèanamh stàilinn ann an Fùirneis Arc Dealain (EAF) agus Fùirneis Ladle (LF)
Tha dealan RP Graphite air a chleachdadh sa mhòr-chuid ann an LF / EAF airson dèanamh stàilinn.Nuair a bhios dealan grafait ag obair ann an LF, thèid an sruth a thoirt a-steach don fhùirneis le dealan grafait, agus bidh stòr teas ann a tha air a chruthachadh le arc dealain eadar deireadh an dealanan agus cosgais fùirneis airson leaghadh.
(2) Airson a bhith a’ dèanamh sileacon meatailteach agus fosfair buidhe ann am fùirneis arc fon uisge
Tha cuid de dhealan gualain le meud mòr (me.700mm-1400mm) air a chleachdadh airson sileacon meatailteach agus fosfair buidhe a dhèanamh ann an fhùirneis arc fon uisge.Tha am pàirt as ìsle den dealan gualain air a thiodhlacadh anns a ’chosgais, a’ cruthachadh arc anns an ìre cosgais, bidh an stuth air a leaghadh leis an lùth teas a thig bho bhith a ’seasamh an-aghaidh cosgais.Mar eisimpleir, bidh timcheall air 100kg de dealan grafait air a chaitheamh airson 1 tunna de sileacon meatailteach.
(3) Airson corundum a dhèanamh ann an fhùirneis dealain
(4) Air a chleachdadh airson a bhith a’ giullachd thoraidhean grafait le cumadh sònraichte
Tha am bàn de electrode grafait cuideachd air a chleachdadh gus diofar thoraidhean grafait le cumadh sònraichte a phròiseasadh
