Heavy plates
Use advice for data set Scope: This EPD is based on a declared unit of 1 ton of average heavy plate (alform®, aldur®, durostat®, toughcore®) produced at the Linz site. This includes thermomechanically rolled, standard-strength and high-strength heavy plates. Roll-bonded clad heavy plates are the subject of a separate declaration. System boundary: The life cycle assessment of average heavy plates produced by voestalpine refers to a cradle-to-gate analysis with options. The following lifecycle phases are taken into consideration in the analysis: Module A1–A3 | Product stage The product stage includes upstream burdens of raw materials (coal, iron ore, pellets, etc.) and the corresponding transports to the Linz production site. Material and energy flows required in the coking plant, sintering plant, blast furnaces, steelmaking plant and heavy plate rolling mill were recorded on site. Electricity is provided at the Linz site in a power station where furnace gases are used as fuel. Since more energy is used than is supplied by this company-owned power station, natural gas and electricity is additionally procured from Austrian networks. Module C3 | Waste treatment Product flows that reach Module D for recycling leave the product system in C3. Environmental impacts resulting from the grinding and sorting of steel scrap are not included. Module C4 | Landfilling Module C4 declares the environmental impacts incurred by landfilling (5 % of the product). Module D | Credits and loads beyond the system boundary The potential for substituting primary steel with a recycling scenario (95 % of the product) is set forth in Module D.
Technical purpose of product or process Rolled plates and hot- or cold-formed heads manufactured by voestalpine Grobblech GmbH are found in the following applications: - Piping systems for large oil and gas pipelines - Manufacture of oil platforms (offshore industries) - Boiler and apparatus construction - Steel construction and bridge building - Vehicle and crane assembly (high-strength and wear-resistant steels)

General comment on data set The products of voestalpine Grobblech GmbH are found in a wide variety of applications. For the placing of structural steels on the market in the EU/EFTA (with the exception of Switzerland) Regulation (EU) No. 305/2011 applies. The products need a Declaration of Performance (DoP) taking into consideration /EN 10025/ and the CE marking. For the application and use the respective national regulations apply. In Austria, for example, it is the /building regulations of the individual states/ as well as the technical stipulations based on these regulations.

Technology description including background system The starting material for the production of heavy plates at voestalpine is crude steel made in the primary route (blast furnace, LD steelmaking plant) at the Linz site. The molten crude steel is cast into slabs using a continuous casting method. After cooling, the slabs are reheated in pusher-type furnaces to 1100–1250 °C. As opposed to hot-rolled steel strips, a four-high rolling configuration, a type of reversing rolling, is used for heavy plates. The four-high mill stands always consist of two work rolls and two backup rolls, with a total of four rolls on each stand. The material is rolled back and forth until it reaches the desired width and length. The product is further processed at the Linz site of voestalpine Grobblech GmbH, among other things, into boiler heads. The plates are formed in a press into heads with desired shapes and sizes. Technical data: This EPD refers to all products of voestalpine Grobblech GmbH (alform®, aldur®, durostat®, toughcore®) in a variety of different steel grades, dimensions, shapes and as-delivered conditions. Specific information on tolerances in the different fields of application can be found in /EN 10029/ and /EN 10163/. The data given in the DoP apply. Declared unit: This EPD refers to a declared unit of 1 ton of heavy plate produced by voestalpine. This includes heavy plates in a variety of different applications; however, the EPD does not refer to roll-bonded clad products.
