Ladle Shrouds Ladle Shrouds

This is a protection device from ladle to tundish,which prevents the molten water from splashing and oxidation.Application of anti-corrosion compound materials in slag line improves the anti-slag erosion property greatly.The promotion of non-baking ladle shrouds will be easy for users to operate and save energies.

    Ladle Shrouds

The products adapt to all types of thin slab caster production line,the optimized design,strict production process control.Then ensure the perfect thermal shock resistance of products,anti-erosion and anti-corrosion properties,and also service life reaches 800minuts even more.

SENs can prevent molten water from re-oxidation,they are divided into internal installed type and external installed type according to the difference of the structure.

    Carbon Rod

This nozzle is designed for the high purity molten water of slab casting steels,it adopts argon insert porous material,which prevents from the build up of AL2O3 effectively,improves the quality of molten steel,and also extends the service life of nozzles.

The application of this products accomplishes the quick exchange of SEN,extends service life of tundish and decreases production cost.The bore of tundish nozzle is sintered zirconia and wholely inlayed,which has better anti-corrosion and anti-erosion properties,and extends working duration of tundish and has better cooperation with stoppers.Therefore it can meet different continuous casting levels.

Others Tap Hole

Isostatic pressed,Mg-C monolithic tap hole,service life reaches 200 heats even more,which reduces the interval periods of exchange.
