Inclined Intensive Refractory Mixer: Refractory Materials Continuous Casting Three Major Parts

2025.7.18 | CO-NELE

In the field of refractory production,especially in the manufacturing of the three major parts of continuous casting(long nozzle,submerged nozzle,stopper rod)with strict quality requirements,efficient and uniform mixing is the key link to ensure product performance and life.Recently,leading companies in the industry have turned their attention to inclined intensive refractory mixers,regarding them as a"secret weapon"to enhance core competitiveness.Behind this technical choice,the significant advantages of inclined intensive refractory mixers in refractory production are highlighted.

Why"inclined"and"intensive"?
Different from traditional roller or horizontal mixers,inclined intensive refractory mixers use a unique inclined mixing disc design combined with high-speed rotating intensive mixing tools(usually paddles or blades).This structure creates a complex and efficient three-dimensional motion trajectory:
Unparalleled mixing uniformity:This is its most core advantage.The combination of strong shear and convection movement ensures that various raw materials(including aggregates,fine powders,binders,additives,etc.with large specific gravity differences and wide particle size distribution)are evenly distributed at the molecular level in a very short time.For the three major continuous casting refractory materials with complex components and extremely high performance requirements,uniformity directly determines their thermal shock resistance,erosion resistance and stability of service life.Problems such as agglomeration and white spots that are difficult to eliminate with traditional equipment are easily solved in front of the intensive mixer.
High efficiency and energy saving,significantly improving production capacity:The mixing cycle is greatly shortened,and usually only a fraction of the time of traditional equipment is required to achieve a better mixing effect.This not only directly increases the output per unit time,meets the growing market demand for the three major continuous casting parts,but also significantly reduces the energy consumption per unit product,which is in line with the trend of green manufacturing.
Low residue,high utilization rate:The equipment is well designed,the unloading is fast and thorough,and there is very little material residue.This means that the waste of expensive raw materials(especially high-performance micropowders and additives)is greatly reduced,effectively reducing production costs.At the same time,the risk of cross-contamination between batches is reduced,and the consistency of product quality is guaranteed.
Gentle treatment of particles,maintaining inherent characteristics:Although the mixing is strong,its working principle can effectively avoid excessive crushing or structural damage to material particles(especially brittle aggregates),and better maintain the original particle size and characteristics of the raw materials,which is crucial for optimizing the final physical properties of refractory materials(such as porosity and strength).
Strong adaptability and flexible process:By adjusting parameters such as rotation speed,mixing time,tilt angle,etc.,it can easily adapt to the mixing requirements of different formulas and batches,providing a flexible process platform for the development of new high-performance refractory materials.
Low maintenance and long life:The sturdy structural design and optimized power transmission system make it reliable in operation and relatively low in maintenance requirements,effectively ensuring the stability of continuous production.
Ideal choice for continuous casting three-piece manufacturing
The continuous casting three-piece works in extremely harsh molten steel scouring and thermal shock environments,and its quality is directly related to the smoothness and safety of the continuous casting process.The requirements for material uniformity,density and performance stability are almost stringent.The inclined intensive mixer has become the only choice for producing such high-end refractory materials due to its excellent mixing uniformity,high production efficiency and excellent material adaptability.It ensures that the materials are in the best homogeneous state from batching to before molding,laying a solid quality foundation for subsequent molding,sintering and other processes,and ultimately producing three continuous casting products with longer service life and higher reliability.
