Ladle Shrouds

Product Description

The long nozzle, typically a slender cylinder wider at the top and narrower at the bottom, features sheet metal reinforcement and an insulation layer connecting the ladle and tundish. It guides molten steel from the ladle to the tundish, preventing air from entering and causing secondary oxidation and nitrogen buildup, thus protecting the casting process and preventing molten steel splashing. Its excellent erosion resistance and the application of composite materials in the slag line area significantly improve the slag corrosion resistance of the finished product. It is a crucial functional refractory material for protecting molten steel during casting to improve billet quality, and its performance directly impacts the smooth operation of the entire continuous casting process. The widespread adoption of non-baking long nozzles facilitates on-site operation and saves energy.

FAQ

Q: Slow Heat Conduction

A: 1. Not preheating according to the standard procedure.
2. Slag influences heat conduction.
3. The crucible has reached its service life.
Q: Crucibe corrosion

A: 1. Adding flux before metal is molten or excessive use of flux.
2. Certain fluxes contain corrosion substances.
3. Fuel containing corrosive substance.
4. Abnormal high-temperature operation may result in glaze layer smelting resembling corrosion.
Q: Top problems

A: 1. Repeatedly top impacted on top area cause oxidation.
2.Slags accumulated arround the top area or between the top area and the furnace cover.
3.Small gape between the top and the furnace cover. 4. Low temperature on top area.
5. Contacting with some matels with lager heat exchanging coefficients.
6. Excentral installation cause not enough space between the top and furnace.
Q: Excessive oxidation

A: 1. Flame in furnace against the bottom of the crucible directly.
2. Low temperature in the top area. 3.Overheated working temperature.
4. Hoisting or moving improperly damages glaze layer.
5. The emergent drain hole is open.
Q: Explosion

A: 1.Heating rapidly while the crucible has damped during transportation or storage.
2. Over rapid heating-up during preheating procedure.
3. The added materials are not completely dried.
Q: Middle or bottom craks

A: 1.Impacted during transportation or installation.
2. Crucible should be placed in the middle of the furnace stack smoothly and stably.
3. An improper graphite stand is used.
4. The existence of great thermal difference in the furnace.
5.Matel ingots in the crucible filled horizontally or diagonally.Metal materials overfilled.
6. Leftover slag or molten matal in the crucible.
