电解铝用阳极钢爪保护环制造技术

本发明专利技术公开的电解铝用阳极钢爪保护环，按重量百分比计，由80～95％的氧化铝粉和5～20％的热固性酚醛树脂制成；所述保护环为环形，由两个半圆环搭接组成，每个半圆环具有两个搭接端头；所述搭接端头呈一级台阶状，每个半圆环的两个搭接端头朝向相反，且两个半圆环的搭接端头互相贴合；该保护环科院解决电解铝生产过程中阳极消耗量大，使用周期短等问题；同时改善电解槽内部环境，降低电解槽炭渣量，提高电解效率。

With the anode electrolytic aluminum ring

With the anode electrolytic aluminum ring disclosed by the invention, according to the weight percentage, from 80 to 95% of alumina and 5 ~ 20% made of thermosetting phenolic resin; the protective ring is an annular ring, composed of 2.5 overlapping, each semicircular ring has two overlapping end; the end is a lap step shape, two overlapping ends of each semicircular ring toward the opposite end of the two lap, and a semicircular ring jointed with each other; the Academy of Environmental Sciences to solve the production process of electrolytic aluminium anode consumption, the use of short cycle; at the same time improve the cell internal environment, reduce the amount of carbon residue in electrolytic cell. Improve the electrolysis efficiency.
