Azovstal Iron and Steel Works
What was done
Modernization of the instrumentation and automation system of the walking-beam furnaces of the heavy-section shop (HSS) of PJSC “Azovstal Iron and Steel Works”.
A set of works on design and software development for the modernization of the automated control system for rail coupling and uncoupling on the rail hardening machine.
A set of works for the modernization of the automatic control system for maintaining the temperatures of the regenerators at the oxygen–nitrogen regeneration station-30 No. 4.
Execution of design works and development of software within the project for modernization of thyristor converters of the rail straightening shop.
A set of works was carried out to restore and commission 1.5 MW frequency converters at the controlled cooling section of the 3600 mill of the plate shop.
A set of works on the development of application software for the APCS of the TG-0.75 turbogenerator of the boiler shop of the coke-chemical production.
Development of application software for the APCS of the TG-0.75 turbogenerator of the boiler shop of the coke-chemical production (CCP) of PJSC “Azovstal Iron and Steel Works”.
A unique project for non-contact measurement of the length of a hot slab was also implemented. Our specialists designed and installed a system for measuring slab length in the process flow. This takes place without stopping the technological process and gives the operator the possibility to react to the metal cutting process if the measured slab length differs from the set value. At the same time, the measurement accuracy is ±5 mm at a slab length of 10,000 mm. The equipment was installed in the transport and finishing department of the converter shop of the works. To create the system, a non-contact laser length and speed gauge, a laser barrier, water flow sensors and air flow sensors were used. In general, the set of sensors provides not only measurement of the slab length, but also monitoring of the operability of the measuring system itself. One of the specific features of this project is the execution of works within the production flow: agreeing the work schedule with the customer made it possible to perform installation works with minute-level accuracy.
