The Development of Intermediate Dry Vibration Materials and Wall Dry Materials

With the great development of world steel production technology, intermediate ladle metallurgy technology has been formed. The tundish ladle has evolved from a simple molten steel transition vessel in continuous casting systems to a refining equipment with multiple refining functions, and the tundish refining technology has also become one of the important technologies for clean steel production. As an important thermal equipment in continuous casting production, the intermediate ladle material not only plays a role in unifying the temperature of molten steel, but also plays a buffering role between the ladle and crystallizer, playing an important role in the quality, cost, and smooth progress of continuous casting production.

The working lining of the intermediate ladle in direct contact with the molten steel must meet the following requirements:

The working lining of the intermediate package has good resistance to slag erosion and slag permeability;

2. The working lining of the intermediate ladle has good high-temperature performance, high fire resistance, high high-temperature strength, good chemical stability under high-temperature conditions, and will not cause secondary oxidation and pollution to the molten steel;

3. The working lining of the intermediate package dry material requires good thermal shock resistance and volume stability;

4. The dry material working lining of the intermediate package has a low thermal conductivity and good insulation performance.

In addition, the construction of the dry material for the intermediate package is simple, and it can be directly put into use without baking. When removed, it is easy to separate from the layer, reducing damage to the intermediate package.

Nowadays, many people are not familiar with some basic information about ladle drainage sand, so as manufacturers, it is necessary for us to briefly explain. In fact, this ladle drainage sand is mainly made of magnesium olivine and Dashiqiao fused magnesium sand as the main raw materials, carbon materials as additives, combined with specific particle size and weight percentage, and mixed to prepare drainage sand, which has been tested,

This structure helps to reduce stress caused by expansion or contraction; Wall wrapping dry materials help to hinder the diffusion and extension of cracks; Helps prevent the intrusion of molten metal and facilitates furnace dismantling and cleaning. This material is constructed on-site using vibration methods. The construction is simple, the construction period is short, and there is no need for maintenance and baking. The working layer can be directly and quickly heated to sinter and put into use.
