Another phase of mill reconstruction is ending in the 1700 Hot Strip Mill at Ilyich Iron and Steel Works of Metinvest Group. The installation of a new hydraulic down coiler for coiling 32 tonne hot rolled coils was completed. The investments in the project amounted to over USD 30 million. The new hydraulic down coiler differs from the existing ones in the shop in a number of important technical characteristics, such as the operation with strips up to 16 mm thick, up to 1,600 mm wide and maximum yield strength of 400 MPa at a coiling temperature. Also, the design provides an order of magnitude higher tightness of coils, an increase in their outer diameter up to 2,060 mm and in their weight up to 32 tonnes. The assembled unit can demonstrate a coiling speed of up to 20 meters per second and its capacity is up to 2.5 million tonens of coils per year.

It was originally planned to invest USD 18 million in the project. Metinvest Group made a decision on additional funding to make the industrial complex as modern and practical as possible from the perspective of the staff working at it. All customers' requirements in relation to the product quality were also taken into account.

Besides the installation of the down coiler itself, a control room, a hydraulic pump station room, an oil cellar room and a booster pump station room were additionally built to provide the unit with the water of required pressure, and where all auxiliary systems of hydraulics, lubrication and power supply were placed. The electrical equipment was installed in the overhauled room of the motor room No. 2. Fire alarms and safety guards were installed, as well as new networks and structures for water supply, sewerage, heat and gas supply. Additionally, electric power and auxiliary equipment was installed, as well as equipment for plate finishing. The company's total investment amounted to $ 30 million.
