Nā hoʻohana a me nā waiwai o nā electrodes graphite:

1. Hoʻohana ʻia i ka umu uila arc steelmaking

Hoʻohana nui ʻia nā electrodes graphite i ka hana ʻana i ka umu uila.ʻO ka hoʻohana ʻana i nā electrodes graphite e hoʻokomo i kēia manawa i loko o ka umu.Ke hele nei ke au ikaika i loko o ke kinoea ma ka ʻaoʻao haʻahaʻa o nā electrodes e hoʻoheheʻe i ke arc, a hoʻohana ʻia ka wela i hana ʻia e ke arc no ka hoʻoheheʻe ʻana.E like me ka mana o ka umu uila, hoʻohana ʻia nā electrodes graphite me nā diameters like ʻole.I mea e hoʻohana mau ai i nā electrodes, ua hoʻopili ʻia nā electrodes e nā hui uila uila.ʻO nā electrodes graphite no ka hana kila no kahi 70-80% o ka nui o nā electrodes graphite.

2. Hoʻohana ʻia i loko o ka umu uila mehana

Graphite electrode submerged thermal uila umu ahi ua nui hoʻohana 'ia e hana ferroalloy, maemae silicon, melemele phosphorus, matte a me ka calcium carbide, etc. Ua ikeia i loko o ka haʻahaʻa o ka conductive electrode ua kanuʻia i loko o ka uku, no laila, i ka hoʻohui i ka wela. hana ʻia e ke arc ma waena o ka pā uila a me ka hoʻopiʻi, hoʻokumu ʻia ka Heat o kēia manawa e ke kūʻē ʻana o ka hoʻopiʻi i ka wā e hele ai i ka hoʻopiʻi.Pono e hoʻopau i kēlā me kēia tona o ke silika ma kahi o 150kg o nā electrodes graphite, a ʻo kēlā me kēia tona o ka phosphorus melemele pono e ʻai i kahi 40kg o nā electrodes graphite.

3. Hoʻohana ʻia i loko o ka umu kūʻē

ʻO nā kapuahi graphitization no ka hana ʻana i nā huahana graphite, nā kapuahi hoʻoheheʻe no ke aniani hoʻoheheʻe ʻana, a me nā umu uila no ka hana ʻana i ka silicon carbide he mau kapuahi kūʻē.ʻO nā mea i loko o ka umu ahi nā mea pale wela a me nā mea e hoʻomehanaʻia.ʻO ka maʻamau, hoʻokomo ʻia nā electrodes graphite no ka conduction i loko o ka pā puhi ahi ma ka hope o ka puʻu ahi, i ʻole e pau mau nā electrodes conduction.

4. No ka hana

Hoʻohana ʻia ka nui o nā graphite electrode blanks e hana i nā huahana like ʻole e like me nā crucibles, nā waʻa graphite, nā mea hoʻoheheʻe wela a me nā mea hoʻomehana o nā umu uila.Pono e hoʻomaopopo ʻia aia ʻekolu ʻano o nā mea synthetic no nā mea graphite i nā mahana kiʻekiʻe, me nā electrodes graphite, nā graphite molds a me nā crucibles graphite.Hiki i ka graphite i loko o kēia mau mea ʻekolu ke maʻalahi i nā hopena oxidative combustion i nā wela kiʻekiʻe, e hopena i kahi papa kalapona ma ka ʻili o ka mea.ʻO ka piʻi ʻana o ka porosity a me ka hoʻolālā wehe e pili ana i ke ola lawelawe.

Hana ʻia nā electrodes graphite me ka coke petroleum a me ka coke needle, a hoʻohana ʻia ka pitch tar lanahu ma ke ʻano he mea hoʻopaʻa.Hana ʻia lākou e ka calcination, batching, kneading, pressing, roasting, graphitization, a me ka mīkini.Hoʻokuʻu lākou i ka ikehu uila ma ke ʻano o nā arcs i nā kapuahi uila.Hiki ke hoʻokaʻawale ʻia nā conductors no ka hoʻomehana ʻana a me ka hoʻoheheʻe ʻana i ka uku i nā electrodes graphite maʻamau, nā electrodes graphite kiʻekiʻe a me nā electrodes graphite mana kiʻekiʻe e like me kā lākou mau hōʻailona maikaʻi.
