TECHNOLOGIES AND AUTOMATIC CONTROL SYSTEMS FOR
THE PROCESSES OF ROLLING AND HARDWARE PRODUCTION
THE TRACKING SYSTEM FOR THE SLABBING PROCESS ON THE
"ROUGHING MILL - CONTINUOUS HOT-ROLLING MILL" COMPLEX
The automatic control system's purpose is to sort out the slabs (blooms), which are sent to the transit rolling, according to the power consumption for the metal deformation per rolling cycle, with a view to saving the energy carriers and increasing the safety of the technological process.
The system's functions are:
- to determine the power consumption for the metal deformation per rolling cycle at the breakdown plant and to estimate the possibility of the slab (bloom) transit rolling, proceeding from sufficient heat content.
- to collect the technological information from the sensors of the main drive, roller tables, photorelays and others on the line "roughing mill - continuous hot-rolling mill".
- to control the metal movement and to record the metal handling along the technological line "roughing mill - continuous hot-rolling mill" as well as to record the temperature and the metal handling time at the points of reference.
- to transfer the data about the slabs (blooms) heat content, their handling time and others to the remote data displaying modules
- to accumulate the statistics, which characterize the rolling process.
- to transfer the information to the factory server of the automated control system division "Steel - rolled stock" and to the other systems.
The system's components:
- Main computer.
- Remote data accumulating units (DAU).
- Remote data displaying units (DDU).
The system's design and hardware possibilities ensure its error-free performance under hard working conditions (dust, high temperature, vibration), which exist at the rolling shops. The error-free performance is achieved due to the use of the special-purpose equipment, produced by "Octagon Systems", "Advantech", "Analog Devices", "Grayhill", IEE, "Rittal".
The system was introduced and is in use on the rolling mills complex "slabbing mill - continuous plate mill 1680" of the OJSC "Zaporozhstal".
The system can be efficiently used on the "breakdown mill - hot-strip mill", "breakdown mill - continuous billet mill" complexes.
