This paper introduces the characteristics of aluminum oxide concentrated-phase transportation technology,and over feeding techniques and control methods of the vertically arranged pre-baking pot in the medium- and small-sized aluminum plant.

In this paper,applying public administration and social regulation I studies the horizontal and vertical configuration of food safety administration,systematically analysis the character,experience and lessons of food safety administration in the developed countries,and the recent innovation trend.

Analyzing CA distance of large pre-baked anode cell;

The paper sets up optimized model for anode exchange sequence of pre-baked anode cell by means of application template designed with usual office software.

The theoretical calculation of the electrolyte temperature variation rule and heat loss during pole changing of 240kA prebaked cell was represented.

After the 80kA self-baking anode was replaced by the prebaked cell, the primary wet cleaning system was reserved, but the running had shown that the smoke dust discharge concentration was over proofed and the system breakdown frequently.
