Ferro-Nickel Rotary Kiln Refractory Products

Ferro-Nickel Rotary Kiln Refractory Products

The rotary kiln refractory layer design and specialized research and development of refractories of our company, better than the old refractory design, the service life is twice as long as the old one . Our company has successfully applied for the patents :

1 . Steel fiber castable (HD-NMJ60): used at the rotary kiln feed inlet and the preheating zone, which has good abrasion resistance.

2 high strength steel fiber castable (HD-NMJ65): used at the transition zone of the rotary kiln, the product characteristics of good abrasion resistance, high density.

3.The anti knot ring material (HD-FK-1): used at the rotary kiln sintered zone, the product characteristic is good for anti ring and anti stripping performance, good compressive strength, good wear resistance.

4. The kiln mouth special castable( HD-YZ-1) for rotary kiln feed outlet and high temperature with retaining ring material zone, the characteristics are good anti erosion, thermal shock stability is superior, abrasion resistance and compressive strength.

 

Technical instructions

Rotary kiln is one of the key equipment in  mineral hot furnace RKEF process.  the rotary kiln operation rate depend on the refractory working layer and refractory materials & installation quality .  

Our company optimize the old refractory working layer design ,use the precast brick and castable to instead of the standard brick design and castable layer design. our refractory layer design has the advantages of: (1)the refractory layer will be better integrated intensity than the old one; (2) easy to control the quality of installation process ; (3) installation process without mould, convenient operation, basic cost can be saved; (4)  the installation process date can be controled less than 25 days.
