Refractory ball is industrial alumina and refractory kaolin as the main raw material, through scientific formula, forming and high temperature forging burn, it has the following features:

1, high mechanical strength, long use period;

2, good chemical stability, does not react with the material;

3, high temperature resistant performance is good, the highest heat temperature can reach 1900 ° C.

 

Fire ball is divided into common refractory ball and high aluminum refractory, refractory ball particularly applicable to chemical fertilizer plant transformation of high and low temperature transformation furnace, furnace, hydrogenation converter, desulphurizing tank and a chamber in the furnace, the scattered gas and liquid, and support, cover and protect the catalyst. High aluminum refractory ball steel mill industry transformation stove and heating equipment.

 

[ regenerative ball product introduction ] :

 

Regenerative ball is also called the ball regenerator, has the linear shrinkage rate is low, the high temperature and high refractoriness under load, corrosion resistance, high strength, heat quantity storage, good thermal shock resistance, good performance, and other significant characteristics of small thermal expansion coefficient of thermal conductivity, is a good refractory material.

 

[Features regenerative ball]:

 

1, the specific surface area of 240 m2 / m3.

2, many balls will be split into small airflow flows, airflow was outdated in the regenerator, the formation of strong turbulence, effective broke through the accumulation of heat on the surface of the body surface boundary layer, and because the ball diameter is small, small transmission radius, small heat resistance, high density, good thermal conductivity, which can realize regenerative burner frequent and rapid directional control requirements.

3, regenerator can use 20 ~ 30 times/h of the reversing, high temperature flue gas flowing through the regenerator in bed after its flue gas emissions have fallen to about 130 ℃.

4, high temperature gas and air flows through the regenerator in the same path can be preheated to only about 100 ℃ lower than the flue gas temperature, temperature efficiency is as high as above 90%.

5, because of the heat storage volume is very small, combined with the ball the flow capacity of the bed is strong, even after heavy resistance increase does not affect the heat change index.

6, regenerative ball has the characteristics of strong oxidation resistance and slag resistance.

7, ceramic ball replacement, cleaning is very convenient, and can be reused.

 

[The application field of regenerative ball ] :

 

Regenerative ball is suitable for the gas and the gas fuel industrial furnace of regenerative combustion system is chosen, especially for regenerative heating furnace of steel industry, the regenerative ladle baking equipment, air separation equipment of air separation industry regenerator regenerative furnace, non-ferrous metal industry, also used in large forging plant regenerative trolley furnace, regenerative electric boilers, the regenerative incinerator industries do regenerative heat carrier.

 

Regenerative ball of gas (blast furnace, converter) and the air double preheating (oil, high calorific value gas combustion air is taken, such as single heat storage mode), can make the regenerative heating furnace smoke less 20-50%, exhaust smoke temperature dropped to less than 150 degrees, yields by 15-20%, billet heating time shortened by 50%, the oxidation burning loss reduce 30-50% of the environmental protection and energy saving effect
