Benefits of Exchange Tundish Nozzle

1. Improve molten steel yield. By using exchange tundish nozzle, continuous casting heat number per tundish life is increased, upper nozzle open time is decreased, accordingly, remaining molten steel, wasted billet ends are decreased, thus the yield of molten steel is improved.

2. Improve billet quality. The first and last heat of one tundish life have great impact on billet quality, with the increase of continuous casting heat number, the number of fist and last heats are decreased, therefore the quality of billet is improved;

3. Stablize production schedule. Before using exchange tundish nozzle, the casting speed could be unstable and unpredictable because of the expand of nozzle diameter, which could lead to accident or shutdown, brings trouble to production. By using exchange tundish nozzle, not only such kind of trouble can be avoided, molten steel can be saved.

4. Lower labour intensity. The increase of continuous casting heat number decreases the construction of tundish and preparation of production, which lowers labour intensity.

Exchange Tundish Nozzle Composition

Exchange tundish nozzles are an integral part of continuous steel casting process. These products are instrumental in controlling the flow of molten steel from tundish to continuous casting. Long casting sequence time. Controlled casting speed.

Exchange tundish nozzles usually comprise a zirconia inner nozzle (often referred to as a "zirconia insert") with a lower grade outer body such as alumina, zircon or bauxite.

Exchangeable Tundish Nozzle Production Process

Exchangeable tundish nozzle was manufactured by both cast process of fine grained alumina method or press process.

Measures to Prevent the Exchange Tundish Nozzle from Getting Stuck

Ensure that there is no deformation in the sliding mechanism of the continuous casting sizing nozzle, there is no foreign matter on the sliding stroke of the exchange tundish nozzle, and the gap between the sizing nozzles is less than or equal to 0.3mm.

The size of the zirconium exchange tundish nozzle is reasonably designed, there is no damage and cracks before use, and the board surface is flat without unevenness.

The production rhythm is stable, the quality of molten steel is qualified, and there is no phenomenon of high and low temperature and molten steel interception.

The personnel for replacing the exchange tundish nozzle are skilled, and there should be no accidental burning or diameter expansion caused by human factors.

FAQ

Q: What is a exchange tundish nozzle?

A: Exchange tundish nozzles are an integral part of continuous steel casting process. These products are instrumental in controlling the flow of molten steel from tundish to continuous casting.

Q: Why is it necessary to exchange tundish nozzles?

A: To maintain optimal performance, prevent clogging, or address wear and damage over time.

Q: What is the result of exchange tundish nozzle clogging?

A: Irregular flow through a exchange tundish nozzle increases the probability of generating a number of quality defects such as re-oxidation of the steel and slag entrapment. Nozzle clogging also affects productivity in that less steel is able to be cast because of the blockage in the nozzle.

Q: How often do exchange tundish nozzles need to be replaced?

A: It depends on factors such as the type of metal being cast, the casting conditions, and the quality of the nozzle, but typically after a certain number of casting cycles or when performance deteriorates.

Q: How is the performance of an exchange tundish nozzle evaluated?

A: By analyzing factors like flow rate, metal temperature distribution, and the quality of the final cast product.
