DABROWA GORNICZA, POLAND

Arcelor Mittal, the world’s leading steel manufacturer, has needed to reduce dust emissions generated during the sintering process in their plant in Dabrowa Gornicza in Poland.
By replacing the two existing ESP filters with modern, hybrid filters that combine the best fabric filter with ESP technology and allow maximum particulate matter emission capture, they ensured the desired dust reduction on the sinter lines.
The hybrid filter consists of three sections. While the first field is designed as an ESP that captures heavier dust particles, the other three are more like a fabric or bag filter capable of capturing the finest dust particles and significantly improving the whole process.
For the better results of the filters, they have also installed dry sorbent and active carbon systems, which have several purposes.
Dry or lime sorbent enables the removal of sulfur dioxide. As a fire-retardant, it reduces combustibility, and its pre-coating material for the bags acts as a protective layer against hydrocarbons and acidic components.
On the other side, the purpose of the active carbon injection is removing of dioxins from flue gas. Since this injection is an ATEX installation, special equipment and protocols are to be used.
Dust mixed with additives from filter hoppers are party recirculated back to filter to save on lime consumption. The rest of it is conveyed to the residual silo and discharged to trucks.
Within this project, our task was to deliver a fully automated control system, to design and deliver electrical panels with redundant UPS supply, and to develop and hot commission PLC and HMI control programs.

ZHANGJIANGANG, CHINA

Shagang Group is widely known as China’s largest privately owned steel producer and is listed among the world’s ten largest steelmakers. The company employs more than 40,000 workers and produces more than 40 million tons of steel annually.

In collaboration with the Austrian company Inteco, Montelektro designed and delivered a five-strand caster system with dynamic mechanical soft reduction for the plant in Zhangjiagang that produces engineering, spring, and bearing steels as well as the highest quality tire cord grades.

Montelektro’s experts developed and commissioned a complete, automated control system consisted of PLC/HMI control programs and electrical panels.
