changes that took place in the production of steel during the years
were significant. Through the use of slide gates the average holding
and treatment times of ladles have increased from 15 minutes to 2
hours - in extreme cases to 8 hours with temperatures as high as 1840C°.
These changes make an opening rate as high as possible more important
than ever, as lower opening rates lead to lower quality and higher
production cost. Based on these new requirements ABT offers a combination
of products and services with the ultimate goal to maximize your
1. When a new product is launched, ABT creates a checklist
for every steel mill. During this step we collect those parameters
that influence the opening rate and are needed to optimize the opening
2. Based on the data collected we make a first proposal for
the expected enhancement of the opening rate and offer a customized
filling sand that meets the customers' requirements.
During a test phase we modify - if required - the component ratio
of the raw materials.
