The hardware configuration and functions of the automatic control system for reheating furnace are introduced, and the operating principles and functions of automatic walking beam control, automatic billet tracking, double cross limit combustion control, etc are described.

Analysis of strip tracking system for linkage of pickling and tandem mill in cold rolling mill;

,take the analyse of strip tracking and accurate location for recovering the trimmer\'s function of the continuous annealing line as object,and describe the basic theory of strip tracking,the relationship between Level 1 tracking and accurate location,as well as the result of researching the key problem.

The paper approaches the model of following slab in walking beam furnace at the hot rolling mill of new steel & vanadium Ltd.
