![]() ![]() The ingot is cold when the process starts at the forge at Scana Steel AB in Söderfors. As a first step the ingot is heated in an oven. The first part of the oven heats the ingot from room temperature to 180☌ immediately. The ingot is then transported through different temperature areas and is slowly heated until it reaches 1150☌. This heating process takes approximately 1-2 days. The next process step is pressing in the forging press. The heated ingot is put in the press and edged into round shape.
