Gas Purifying Plant Project in Koverhar
At the turn of August-September, the installation of the blast furnace started as the first part of the modernization program of the steelworks of Ovako Wire Oy Ab in Koverhar, Finland. It contains a new gas washer and a related water treatment plant. Betamet takes care of all equipment and pipe line installations.
This is the first project for Betamet in the Koverhar plant. Kim Michelsson, project manager from the Koverhar plant, says that the bidding competition was very tight, and so is the schedule of the installation. The new plant has to be in operation before winter comes. It will be started at the middle of November when there is a three day downtime for connections in the whole plant.
– Cooperation has started well. Expectations are high that Betamet will manage creditably in this installation work on the tight schedule, Mr. Michelsson states.
Challanging task
The plant in Koverhar will change in blast furnace gas purification from dry filtering into wet washer techniques. According to Mr. Michelsson, they will be prepared for that still purer gas will be a suitable fuel for the new power plant built later in the factory. More efficient gas purification reduces environmental emissions as well.
The installation work is especially demanding because the new gas purifying plant will be a part of the old equipment. The gas washer, weighing about 60 tons and being 26 meters high, has already been lifted with two 400 ton cranes in place.
The diameter of the clarifier for the waterworks is 27 meters. In addition, pumps, a sludge press, two cooling towers and channel systems, among others, will be installed there.
Before the downtime for connections, 30 Betamet’s fitters and 4 supervisors work with installations as daywork. During the downtime for connections, 22 people work 24 hours a day.
Steel for the European car industry
About 400 people are working in the area of the Koverhar factory. The factory will produce about 600 000 tons of steel slabs a year which will be rolled in Ovako Wire’s rolling mills in Dalsbruk, Finland and Alblasserdam, Holland. The majority of the products goes to the European car industry where they will be made into different components.
