No 2 LD Plant, Muroran Works, produces various kinds of steel with very high productivity establishing a new world record of 2 762 heats per month in April 1970. By introducing a mini process computer, a unique control system has been brought into the plant.
The system has achieved splendid accomplishment, e. q. improvement of the end point control, reducing the workers required and mechanization of tabulation.
The system embodies three features.
1. Linkage with the central computer: The process computer has been directly linked with the large central computer.
2. Display units: Cathode Ray Tube (CRT) has been introduced instead of typewriters first in steel making process control system.
3. Dynamic temperature control: The bath temperature during blowing is measured by the sub-lance and taken into the process computer.
