Hongtai high quality alumina refractory ball for hot blast stoves, heating converters

Refractory ball

Refractory balls are made of industrial alumina and refractory kaolin as the main raw materials through scientific formula, forming and high-temperature calcination.

The main raw materials of refractory balls are industrial alumina and refractory kaolin, which are divided into ordinary refractory balls and high alumina refractory, used in the sulfuric acid and fertilizer industries, hot blast stoves and other equipment.

Refractory ceramic ball Refractory ball is made of industrial alumina and refractory kaolin as the main raw materials through scientific formula, forming and high temperature calcination.

High alumina refractory ball nature: 

1. High mechanical strength, long service life;

2. Good chemical stability, no chemical reaction with materials;

3. Good high temperature resistance, the highest heat resistance temperature of the refractory ceramic ball can reach 1900 degrees.

It is especially suitable for high and low temperature shift furnaces, reformers, hydrotransformers, desulfurization tanks and methanizers in chemical fertilizer plants, and plays the role of dispersing gas and liquid, and supporting, covering and protecting catalysts. Refractory ceramic balls can also be used in hot blast stoves and heating conversion equipment in the iron and steel industry. 

Types of refractory balls:

The refractory ball bed is the core of the spherical hot blast stove, and the refractory ball is the key to the formation of the pebble bed. According to the different materials, it can be divided into three different types.

High aluminum quality-this is the first classification. The refractoriness of this type of refractory ball can reach more than 1,750 degrees Celsius. It is often used in the high temperature area of the pebble bed, but due to its thermal stability and slag resistance defects, it may cause cracks or make the bed layer of the pebble bed insufficient air permeability. The ball must be cleaned regularly in a short period of time. It can ensure normal use. It is necessary to pay attention to the highest refractoriness that it can achieve, and it should not exceed its maximum endurance range, otherwise it will have a great impact.

Silica-this type is an acidic refractory material, which can be used not only in the high temperature area of the pebble bed, but also under conditions of large gradient temperature changes. Refractory balls of this kind of material tend to have poor alkali resistance, and it will be difficult to clear the balls.

Magnesium aluminum-this is the most advantageous of all types. It not only has alkali resistance, avoids slag erosion, but also has strong thermal stability. Therefore, this type is often used in areas where high temperature fluctuates frequently. Due to its own advantages, it has become one of the most commonly used types in ironmaking enterprises.

The above three different types of refractory balls can be said to perform their own duties, and the performance effects that can be achieved are completely different. When selecting, it is necessary to select a suitable type according to actual needs to ensure the normal operation of the entire operation link. If you choose improperly, it may cause unnecessary work troubles.

Refractory ceramic balls are divided into ordinary refractory balls and high alumina refractory balls. Common refractory balls are suitable for converters and converters in the sulfuric acid and fertilizer industries, and high alumina refractory balls are suitable for hot blast stoves, heating converters and other equipment in urea, steel and other industries.

The main problem encountered in the use of refractory balls is that high-aluminum refractory balls have high hardness and brittleness. Dry grinding can easily cause cracking of the balls and pits on the surface of the balls, resulting in very high wear. The method of polishing the balls to pick out the balls with high cracking or wear.
