As the aluminum industry facing the strictly environment claim and the drastic market competition, it is very important to reconstruct of self-baking cell replaced cell by the original pre-baked cell.

Two transform programs for self baking anode type cell were proposed, economic analysis was performed, and prebaked transform technique for small type cell was probed into.

In this paper, a control system of tobacco-baking which employs 89s51 as its core and has functions of self-study and multiple technological curves is designed.
