MagDryLine

MagDryLine was developed to lower and stabilise hydrogen pickup in tundish

–  No organic components in binding system –  Less hydrogen and no carbon to steel

MagDryLine has also reduced the amount of crop loss in the beginning of casting

− Before introducing MDL client scrapped 5m, after initialising only 0,5m

Additional solutions Installation

Do it better, with Bet-Ker.

Cruiver − Simple design that consist of two

parts §  Upper part for material feeding §  Lower part for molding the material

and stabilise the consumption

− Maintenance-free §  No clogging risk §  High wear resistance materials

Additional solutions Installation

New lining design − Back lining and wear lining molds designed with

round bottoms §  Whole wear lining can be installed at once §  Improves the steel yield §  Stabilise and decrease the wear lining material

consumption

Additional solutions Curing

Do it better, with Bet-Ker.

Wear lining can be cured with two different options: 1.  Back lining heat −  If back lining heat is higher than 200 °C −  Energy savings −  Extremely good surface quality for wear lining

2.  Heating lid −  If back lining heat is lower than 200 °C −  Lid is the primary heat source for forming the bond in the material

Additional solutions Heating lid

Air inlets

1.  Electromotor 5,5 kW 2.  Fan wheel 3.  Heating unit 2 x 80 kW
