Casting ladle rims

June 2010 – De Boer Snijbedrijf regularly cuts the rim segments for the steel casting ladles used in a large steel factory. The ladle pours the liquid steel in a long, flat strand, which is then rolled. Liquid steel is incredibly hot, so it's not surprising that the ladle rims get damaged and need replacing quite frequently.

De Boer Snijbedrijf regularly supplies the cut-to-size steel parts for the casting ladles used by Microtechniek from Beverwijk. To protect casting ladles against the heat of the liquid steel, they are lined with heat-resistant bricks. Microtechniek makes recessed holes in the ladle rim segments. Then the segments are welded together to make a ring about eight metres across. The next step is to position the ring on the ladle. It keeps the heat-resistant bricks in place, preventing damage to the edge of the ladle.

The materials supplied by De Boer Snijbedrijf have to be straight and burr-free so that the steel ring can be positioned flush to the ladle, providing optimal protection. Even so, the rings wear out quickly and they have to be replaced regularly. De Boer Snijbedrijf and Microtechniek work together well and so new steel rings are produced quickly, efficiently and professionally.
