The next stage of the mill reconstruction is coming to an end at the 1700 sheet-rolling shop of the Ilyich Steel Plant of Metinvest Group. Installation of a new hydraulic coiler for unwinding 32-ton hot-rolled coils was completed. The investment in the project is over $ 30,000,000.
The new hydraulic coiler differs from those already operating in the workshop in a number of important technical characteristics, such as working with strips up to 16 mm thick, up to 1600 mm wide and a maximum yield point at a coiling temperature of 400 MPa. The design also provides a much higher winding density for rolls, an increase in their outer diameter up to 2060 mm and a weight up to 32 tons. The assembled unit can demonstrate a reeling speed of up to 20 m /s, and its capacity is up to 2,500,000 tons of coils per year.
It was originally planned to invest $ 18 million in the project. Metinvest Group has made a decision on additional financing to make the industrial complex as modern and practical as possible in terms of staff work. We also took into account all the customers’ requirements for product quality.
In addition to the installation of the coiler itself, a control post was additionally built, rooms for a hydraulic pumping station, an oil pump and a booster pump station to provide the unit with water of the required pressure, in which all auxiliary systems of hydraulics, lubrication and power supply were placed. The electrical equipment was installed in the overhauled room of the turbine hall No. 2. Fire alarms and safety fences were installed, new networks and facilities for water supply, sewerage, heat and gas supply were installed. Additionally installed power and auxiliary equipment, as well as equipment for sheet-forming. The final investment of the company is $ 30,000,000.
Metinvest-Engineering is the general contractor for the project.
For hydraulics, mechanics, process engineers, coiler operators and control personnel, equipment manufacturer Primetals conducted an exercise. In the context of the COVID-19 pandemic, it was held remotely in the format of Skype conferences.
Now the specialists have begun hot commissioning and adjustment of the coiler parameters for different product mix of the 1700 sheet-rolling shop.
“The implementation of this stage of modernization of the 1700 mill completes a large-scale complex of works to increase the competitiveness of our rolled metal products. The new coiler will allow to expand the “bottlenecks” of production and expand the assortment line of products in terms of thickness and strength class with the quality indicators of the hot-rolled coil required for the customer. In addition, we will be able to increase the maximum coil weight in the range from 20 to 32 tons, depending on the strip width, ”noted Taras Shevchenko, General Director of Ilyich Ilyich Steel Plant of Metinvest Group.
As a reminder, in April 2020 Metinvest Group attracted a credit line in the amount of 9,800,000 euros to finance this project. The facility is covered by an Austrian export guarantee issued by the export credit agency Oesterreichische Kontrollbank Aktiengesellschaft (“OeKB”). Raiffeisen Bank International was the only creditor.
