The advantage and feature of tundish dry vibration mix

 

1. Overview of tundish dry vibration mix

Dry vibration mix is an amorphous refractory that is formed by vibration without adding water or liquid binder. Under the action of vibration, the material can form a dense and uniform whole, which can be strengthened by thermosetting bonding agent or ceramic sintering agent when heated. Vibrating material is composed of refractory aggregate, powder, sintering agent and admixture. Its characteristics are: this kind of material is easy to flow under the action of vibration force, and the powder can fill the very small pores between particle accumulations even under the action of small vibration force, and obtain a dense body with higher filling density. In use, it is heated to form a working surface with certain strength. However, there are still parts of the non-working face that are unsintered and present the original dense packing structure.
This structure helps to reduce the stress caused by expansion or contraction; Helps to hinder the spread and extension of cracks; Helps prevent the intrusion of molten metal, and facilitates unpacking and cleaning. This material is constructed on the construction site by vibration method, which is simple in construction, short in construction period, does not need maintenance and baking, and can directly raise the temperature quickly and put the working layer into use.

2.The characteristics of tundish dry vibration mix

2.1 Rapid construction, the use of suitable construction methods can complete the operation within a few minutes, which greatly reduces the labor intensity of the workers and reduces the safety hazards caused by human factors.?
2.2 Dry molding can be put into use without long-term baking, which reduces energy consumption and greatly speeds up the turnover of the tundish.
2.3 Good anti-corrosion performance, improve the life of the lining, meet the demand for long-term pouring steel, and greatly reduce the cost of steelmaking.
2.4 Relying on phenolic resin as a binder to obtain demoulding strength, reducing phosphorus pollution and purifying molten steel, which can meet the requirements of smelting different steel grades, but resin-bonded dry vibration mix are easy to increase carbon.
2.5 There is a reasonable line change under various temperature conditions, which is easy to turn over.
2.6 Compared with the use of paint, the tundish dry construction method overcomes the shortcomings of manual application, especially the significant increase in service life meets the requirements of continuous operation in the steel industry. It has been rapidly applied in recent years and has shown the trend to completely replace tundish coatings.
