The Rauma sawmill begins testing

Construction and installation at Rauma pine sawmill are proceeding according to schedule. The saw line building has been completed and the saw line machinery has been installed, and the interfaces are already being tested. Installation is also nearly complete in many of the other departments, like the debarkers and the green sorting line, and the interfaces are being tested there as well.

The first production test run will take place this spring and the Rauma sawmill is scheduled to begin producing pine sawn timber in the third quarter of 2022. Thanks to the state-of-the-art technology, it will be Metsä Fibre’s most modern and technically advanced sawmill ever. Furthermore, it will be a big leap forward in the industry, both in terms of technology and efficiency, and it will lead the way to the future of sawn timber production.

Technology delivers efficiency and sustainability

At our new Rauma pine sawmill we are using technology to ensure the most efficient and effective use of wood raw material, and machine vision and AI will be used to get the most and the best from each log. The sawmill will also be integrated into our Rauma pulp mill so that every part of each tree is used and nothing is wasted, not even wood chips or sawdust. The wood we use has full traceability and comes from certified or controlled forests.

Metsä Fibre targets large industrial customers worldwide. For more information, please contact your local sales.

The automated systems in the new mill gather lots of data, including data about sawn timber grade and quality, and drying properties. This data is then connected to each specific lot of sawn timber, which means that our customers can see the properties of the sawn timber in each lot and choose the right lot for their needs.

The technology makes the sawmill more efficient and it ensures a high level of product quality. It also enables the optimum use of wood in each individual log, for the best resource efficiency. Smart systems with machine vision ensure smooth, uninterrupted production, all the way from log sorting to sawing to drying and loading. Artificial intelligence, together with machine vision, is also used to identify and sort timber by grade and by moisture level, and to remove defects. This ensures our customers receive accurately graded sawn timber with consistent quality.

Although Rauma sawmill is highly automated, Metsä Fibre’s skilled and highly competent staff have full visibility of operations from the central control room. Here, they monitor accurate, real-time data to ensure uninterrupted production and high quality at all stages of the process. Quality checking begins with accurate grading and the removal of defective pieces right at the start of the production chain to ensure more consistent quality throughout the production process. During log sorting, the logs are X-rayed to measure quality deviations, knots and knot frequency. After measurement, the control system grades the logs into sawing batches and links them to the intended final products. The flow of timber in the sawline is also continuously monitored by special cameras that detect defective pieces. Automated robotics remove defective pieces without manual intervention.

The new Rauma sawmill will be integrated with Metsä Fibre’s Rauma pulp mill, which is located on the same site. The synergies between the sawmill and the pulp mill will bring benefits to energy production, utilization of side streams, logistics and services. In the future, this investment will enable both Rauma sawmill and pulp mill to operate without using any fossil fuels.
