Bulk Density 2.2-2.7g/cm3 Low Cement Refractory Castable with CaO Content of 0.1

High Alumina Castable

Introduction

High alumina castable is a kind of refractory castable which uses high alumina raw material as aggregates and the powder and then be added with the binding agent. High aluminum refractory castable has high mechanical strength, good thermal shock resistance, good corrosion resistance.

Advantages

For the advantage of high alumina castable, it can be summarized as follows:

1. Using less cement. compared to traditional refractory castable, the calcium content in high alumina castable is about a quarter to one-third of that in traditional castable. Thus, reducing the number of the low melting phase in high alumina castable, finally improving the high-temperature performance.

2. Low water consumption. during the construction, we only need to add about 6-7% water of castable weight into the high alumina castable. therefore high alumina castable has high density and low porosity.

3. High alumina castable has high room temperature curing strength, and the strength will not decline even after medium and high-temperature processes. Besides, the strength absolute value of high alumina castable is 3-5 times as high as that of traditional castable.

4. High alumina refractory castable has steady volume stability at high temperatures. Even though high alumina castable belongs to unfired refractories, its volume shrinks only a little after drying dehydration and calcination.

Application

High alumina castable is mainly used for furnace lining of the boiler, blast furnace hot blast stove, heating furnace, ceramic kiln and various industrial furnaces.

1. What is the difference between Refractoriness and Working temperature?

Refractoriness: the refractory material withstands high temperature without melting and softening performance in the absence of load resistance. Usually working temperature is less than refractoriness at about 350-400°C.

2. How is the products’ quality?

The products are strictly inspected during each procedure, so the quality could be absolutely guaranteed.

3. How about the service life for our fire brick?

1~2 years’ warranty-- It is our leading advantage in the refractory industry benefits by our superior quality control system.

4. What is the service life of the bricks?

The service life of different bricks is unlike. It also depends on your using condition and method.
