Nozzle filling compound

Nozzlex nozzle well filler is a free-flowing refractory particular material used in the ladle or tundish sliding gate to prevent skulling and steel freeze-off and ensure easy opening at the start of casting.

Nozzlex is a highly refractory, granular product with selected particle size and distribution, which remains flowable at high temperature, ensuring consistent and trouble-free ladle slide gate operation.

For achieving the best results:

• Nozzlex should be pre-heated at around 100°C for about an hour to drive out any physical moisture.
• The nozzle cavity should be cleaned of slag and any refractory particles before application.
• The quantity of Nozzlex to be applied should be carefully determined so that the nozzle cavity is entirely filled, with a slight mound at the nozzle top. It should be applied with a suitable applicator to ensure that the product is applied at the proper place.   Function

  Successful operation of ladle slide gate depends to a large extent on the use of proper nozzle filling compounds and operating conditions, as well as nozzle well block geometry. To meet these demanding conditions, the nozzle filling compounds should have sufficient refractoriness to prevent sintering of the particles at high temperature, and ensure good flowability.

    Benefits
  • Good nozzle opening performance is ensured
  • The need for oxygen lancing for opening the slide gate nozzle is minimized
  • Well block and nozzle life is increased
  • The life of the slide gate plate is extended
  • Due to good nozzle opening performance, Nozzlex drastically reduces the incidence of ladle return from the casting platform.
