Our TunSprayR tundish lining system provides unmatched consistency and quality. In fact, the past two world records for the number of consecutive heats of carbon steel continuously cast on either a single-strand or double-strand caster were set by AK Steel. Their Middletown, Ohio plant recently cast 2156 consecutive heats of steel using our TunSpray material.
The sequence was ended on May 4, 2010 for a planned maintenance outage.
During the 59-day sequence, a total of about 103 miles of carbon steel slabs
were cast. Congratulations to AK Steel on their accomplishment. Read more.
