Unshaped Refractory Materials for Metal Mixer and Ladle of Iron

Unshaped Refractory Materials for Metal Mixer and Ladle of Iron

Unshaped refractory materials, also known as monolithic refractories, are used in various parts of metal mixers and ladles for iron in the steel and foundry industry. These materials are preferred for their ease of application and versatility. AGRM supply types of unshaped refractories used in metal mixers and ladles.

The choice of refractory material depends on the specific application, operating conditions, and requirements of the metal mixer and ladle. It’s crucial to consider factors like temperature, abrasion resistance, thermal shock resistance, and corrosion resistance when selecting refractory materials for these applications. Additionally, these materials play a significant role in extending the lifespan of the equipment and ensuring the quality of the metal produced.

What Kind of Unshaped refractory materials for Iron Industry?

TypesUnshaped refractory materialsIntroduction
Type 1Working Layer CastableThe working layer castable is applied to the surfaces where direct contact with molten metal occurs, providing a durable and erosion-resistant lining.
Type 2Permanent Layer CastableIt offers durability and thermal stability, ensuring the longevity of the refractory lining in the specific areas where it is applied.
Type 3Iron Ladle Mouth Feed CastableThe material is tailored to provide a reliable and long-lasting lining in the critical mouth or feeding area of iron ladles.
Type 4Spinel CastableThe inclusion of spinel in the castable enhances its refractory properties, making it suitable for demanding applications in metal mixers and ladles.

Type 1:Working Layer Castable

The Working Layer Castable is a refractory material designed for use in the working layer of metal mixers and ladles. This castable typically comprises a mixture of refractory aggregates, binders, and additives. It is engineered to withstand the harsh conditions of molten metal contact, abrasion, and thermal cycling.
