In the annealing process of cold rolled strip, the batch annealing has been a prevailing method.
Although several improvements have been made in this field for these twenty years, some difficulties in saving personnel, labour environment, and productivity still remain.
UAD (Unitized Annealing Department) system. was developed to solve these problems in 1966.
The newest system was adopted at Kakogawa Works, Kobe Steel, Ltd. and has been successfully in production.
UAD system consists of loose coiling unit, “VERTOHORT” tight coiling unit, box shaped furnaces, and automated transfer cars, and it can handle the maximum charge weight of 100 t for open coil and 200 t for tight coil annealing.
The advantages of UAD are as follows.
1. Lower capital investment.
2. Lower processing cost.
3. Excellent productivity.
4. Clean strip surface.
5. Uniform quality along the full strip length.
6. Easy adoption of full automatic operation.
