СПОСОБ ЗАЩИТЫ ГРАФИТИРОВАННЫХ АНОДОВ МАГНИЕВЫХ ЭЛЕКТРОЛИЗЕРОВ ОТ ОКИСЛЕНИЯMETHOD FOR PROTECTING GRAPHTED ANODES OF MAGNESIUM ELECTROLYZERS FROM OXIDATION

Изобретение относитс  к области металлургии легких металлов, в частности к электролитическому производству магни .This invention relates to the field of light metals metallurgy, in particular to the electrolytic production of magnesium.

Известен способ защиты графитированных анодов магниевых электролизеров от окислени  путем нанесени  на выступающую из электролизера головку анода сло  защитного материала.There is a known method of protecting graphitized anodes of magnesium electrolysis cells from oxidation by depositing a layer of protective material on the anode head projecting from the anode cell.

Предложенный способ отличаетс  тем, что в качестве защитного материала используют вещества, способные к коксованию и полимеризации , например каменноугольный пек, причем головку анода и защитный материал размещают в опалубке. Это позвол ет увеличить срок службы анода.The proposed method is characterized in that coking and polymerization substances, such as coal tar pitch, are used as protective material, with the anode head and protective material placed in the formwork. This makes it possible to increase the service life of the anode.

Пример. При монтаке электролизера на верхнюю часть анодов устанавливают опалубку . Примен емый в качестве защитного материала каменноугольный пек предварительно расплавл ют и заливают в опалубку. Температура головки апода на работающем электролизере 300-400°С. При этой температуре нек, наход сь некоторое врем  в раснлавленном состо нии, заполн ет поры графита. ЗатемExample. When mounting an electrolyzer, formwork is installed on the top of the anodes. Used as a protective material, coal tar pitch is pre-melted and poured into the formwork. The temperature of the apod head on a running electrolyzer is 300-400 ° C. At this temperature, some, being in a molten state for some time, fills the pores of the graphite. Then

происходит его коксование, в результате чего образуетс  тверда  защитна  оболочка. По мере проникновени  пека в поры и его коксовани  в опалубку заливают новые порции пека. Образующийс  защитный слой снижает поступление кислорода к поверхности графита анода.coking occurs, resulting in a solid protective sheath. As the pitch penetrates the pores and cokes it into the formwork, new portions of the pitch are poured. The resulting protective layer reduces the oxygen supply to the surface of the graphite anode.
