Cost effective Continous Casting
Continuous casting requires exceptional refractories in order to successfully carry out its mission. SQ Insertec manufactures and distributes a multitude of refractory products for the different types of continuous casting that exist.
Insulating cover powders for tundish and spoons
Protection of the broth, reducing radiation losses
Different ranges of basity and contents in C
Wide range according to customer needs
- ACIDS: MOLCOAT 250; MOLCOAT 350
- BASIC: MOLCOAT 500; MOLCOAT 350
- NEUTRAL: MOLCOAT 50B, MOLCOAT 50B-EX; MOLCOAT 50L; MOLCOAT LC; ISOLAN A
- Refractory foot used as filling material in joints of
- refractory bricks
- joints of buzz
- impact plates
- Refractory foot as backrest in tundish behind the work lining (cold plates).
- Dry or wet application // High refractoriness
Tundish lining -TUNSIL
- Insulating and refractory boards. Acid lining (silica) is usually used for small to medium size of tundishes and for billets. Excellent deskulling.
- No need of preheating before teeming.
Tundish lining – TUNMAG
- Refractory boards. Basic lining (MgO) is usually used for medium to large tundishes. Use for sequential casting.
- No need of preheating before teeming. Excellent deskulling.
Sealing Cement – SIDERCOL
- Several formulations according to the application.
- They are refractory glues or cements to make joints between the insulating assembled boards to prevent metal penetration during teeming.
Tundish Cover – MOLDCOAT
- Insulating cover powders protecting the surface of the steel from oxidation.
- Special formulations are available according to the tundish lining (basic or acid) and thesteel alloys.
Starting Devices – ALUVAC
Before teeming, the stopper rods and tundish nozzles have to be well preheated to avoid freezing when the teeming starts.
- Preheating cones (made with this very high insulating material). Such cone concentrates the heat on the nose of the rod and the tundish nozzle during preheating.
- Starting tubes and floating rings: The purpose is at thebeginning of the teeming to leave a heel of steel in the bottom of the tundish to avoid freezing steel to get inside the tundish nozzles.
