The Severstal company has started shipping the first bimetallic sheets for the Zvezda shipbuilding complex. A batch of 100 sheets is intended for the construction of the bow of the hull of the nuclear icebreaker Rossiya.
The bimetal will be used for the ice protection of the atomic icebreaker, the so-called ice belt of the ship. This is a reinforced lower part of the hull that directly resists ice.
The bimetal is produced at mill 5000 of the sheet-rolling shop at the production site in Kolpino, using a new batch rolling method.
“Specifically for this project, in less than six months, a new site for assembling bimetallic packages was organized at the Severstal production site in Kolpino. And in October, the new site completed the modernization of equipment to accelerate the stripping of the main layer of bimetallic sheets in the range of thicknesses from 10 to 250 mm, which will increase production by 900 tons per year. The processing time for one sheet has been reduced from 56 to 8.5 hours,” said Dmitry Vanev, General Director of the Izhora Pipe Plant.
Also, the production of rolled metal for the first vessel of the Leader project is provided by mills 2000 and 2800 of the Cherepovets Metallurgical Plant.
“Severstal” is the main supplier of rolled metal for the construction of the icebreaker, the company fully met the need for ship steel for the construction of embedded sections.
