Production process starts from steel slabs, most part of which come from Metinvest's Azovstal Iron and Steel Works. In its yard Metinvest Trametal may store up to 80.000 tons of material.
At the plant slabs are flame cut to the size related to the final dimensions of the plate to be produced. The slabs are reheated in one 3 ways pusher furnace which operates with natural gas.
After exiting from the reheating furnace, slabs move through descaling station for water scale removal under pressure of 220 bars.
Quarto reversing rolling mill
Slabs are then rolled by a quarto reversing mill where they pass forth and back between the rolls in order to reduce the thickness. Accurate thickness tolerances are guaranteed through a sophisticated on line x-ray gauge meter.
When coming out from the rolling mill, the plate levelling is made automatically on hot leveller on line.
Plates are marked with sticky tax on the surface and edges. During the production process from daughter slabs to be rolled to the final shipment, products are controlled with bar code tag.
The plates are normally supplied with edges as rolled. On request plates can be delivered cut edges with cutting made off line.
Plates (up to 24000 mm length, 3250 mm width) can be supplied with different types of heat treatments (normalized in furnace, normalized and tempered, annealed) according to applicable norms and/or customer specification using a roller type furnace.
