Name:refractory pellet;

Main raw materials: industrial alumina and refractory kaolin;

Classification: ordinary refractory pellet and high aluminum refractory pellet;

Characteristic:

1. High mechanical strength and long period of use;

2. Good chemical stability and no chemical reaction with the material;

3. The high temperature resistance is good, and the maximum heat resistance of the refractory porcelain ball can reach 1900 degrees;

Refractory pellet is divided according to aluminum content:

1. Ordinary refractory pellet:used for reformer and shift converter of sulphuric acid and chemical fertilizer industry;

2. High aluminum refractory pellet:used for hot blast furnace, heating converter and other equipment in urea and steel industry;

Refractory pellet is divided according to classification:

1. Refractory pellet:Al45-90,Si10-70,Fe≤1;

2. Corundum refractory pellet:Al90-98,Si0.5-5.0,Fe≤0.5;

3. Low silicon refractory pellet:Al90-98,Si≤0.3,Fe≤1;
