Study on Preparation of Carbonaceous Pelletizing in Industrial Silicon Production

Abstract

In this paper, the pelletizing as carbonaceous reducing agent of industrial silicon were prepared using anthracite fine, petroleum coke powders, charcoal powders and silica fume as materials, and starch D as binder, the effects of different wetting agents on performances such as compressive strength of fresh pelletizing and dry pelletizing, the heat intensity and the shatter strength were researched. The results show that: when starch D mass content was 3.04% and sodium hydroxide solution was used as wetting agent, the performances were better, and compressive strength of fresh pelletizing was 1401.1N, compressive strength of dry pelletizing was 8109.3N, the heat intensity was 95.34%, and the shatter strength was 99.09%.
