• Aikace-aikacen lantarki na graphite

Graphite electrode yana da fa'idar amfani da yawa, galibi ana amfani da shi a cikin tanderun ƙarfe na lantarki, tanderu thermal, tanderun juriya, da sauransu.

1. Graphite lantarki da ake amfani da baka steelmaking makera

Babban masu amfani da wutar lantarki tanderu steelmaking, lantarki tanderun steelmaking shine amfani da graphite electrode a cikin tanderu halin yanzu, da karfi halin yanzu a ƙananan karshen na lantarki ta hanyar iskar gas fitarwa, da amfani da baka samar da zafi ga narkewa, bisa ga girman wutar lantarki tanderu iya aiki, tare da daban-daban diamita na graphite lantarki, domin ci gaba da yin amfani da na'urori masu auna sigina, lantarki ta hanyar lantarki thread hadin gwiwa dangane, The graphite lantarki amfani a steelmaking lissafin kusan 70-80% na jimlar adadin graphite lantarki.

2. User ma'adinai zafi wutar lantarki tanderu

An fi amfani da tanderun ma'adinai don samar da ferroalloy, siliki mai tsabta, phosphorus mai launin rawaya, matte da calcium carbide.Siffofinsa sune cewa an binne kasan na'urar lantarki a cikin cajin, don haka baya ga zafin da ke haifar da baka tsakanin farantin da cajin, na yanzu ta hanyar cajin ta hanyar juriya na cajin kuma yana haifar da zafi, kowannensu. ton na silicon yana buƙatar cinye kusan 150kg/ graphite electrode, kowane ton na rawaya phosphorus yana buƙatar cinye kusan 40kg graphite lantarki.

3, domin juriya tanderu

Production na graphite kayayyakin da graphitization makera, narkewa gilashin makera da kuma samar da silicon carbide makera ne juriya tanderu, tanderun shigar m dumama juriya, shi ne kuma abu na dumama.Gabaɗaya, ana shigar da na'urar graphite conductive a bangon kan tanderun a ƙarshen murhu, don haka ba a ci gaba da cinye na'urar ba.
