Siemens modernizes gas cleaning system for blast furnace of Ovako Wire Oy Ab

With the new gas scrubber, up to 125,000 Nm3 per hour of blast furnace gas can be cleaned. The modernization project is to be completed in November 2009.

Ovako Wire Oy belongs to the Ovako Group, a leading European manufacturer of long special steel products. The company produces around two million metric tons per year of low-alloy and carbon steels in the form of bars, wire rod, tubes and rings for applications in the manufacture of roller bearings and in heavy vehicle and automotive production and machine construction.

In the steel mill at Koverhar, in South Finland, around 600,000 metric tons of steel per year are produced and cast into billets for further processing at other Ovako locations. To ensure that environment standards are still observed after the planned modernization of the blast furnace has taken place, the relevant gas cleaning system will be brought to the latest state of the art.

The Simetal cone scrubber supplied by Siemens for this purpose will reduce the dust and water content in the blast furnace gas to values that meet environmental standards and increase the service life of the downstream plant components.

The system is designed such that it can be used reliably throughout a wide range of gas compositions. The operating conditions that are expected after modernization of the blast furnace were already taken into account when designing the scrubber.

With some 170 newly installed blast furnaces and a large number of modernized blast furnaces, Siemens is the world's leading supplier of blast furnace technology.
