Magnesia Hercynite Brick

Short Description:

Magnesia hercynite bricks have the advantages of chromium-free environmental protection, good thermal shock stability, good kiln skin hanging ability, good corrosion resistance, low thermal expansion and low thermal conductivity, and better structural flexibility. In practical applications, the brick has a service life of more than 1 year, the kiln skin is hung quickly in the firing zone, the thickness of the kiln skin is uniform and stable, the refractory bricks have no large flaking phenomenon, and there is no flaking phenomenon of refractory bricks when the kiln is stopped. The temperature of the kiln barrel is low, and the heat energy less loss.

Description


Magnesia hercynite bricks have the advantages of chromium-free environmental protection, good thermal shock stability, good kiln skin hanging ability, good corrosion resistance, low thermal expansion and low thermal conductivity, and better structural flexibility. In practical applications, the brick has a service life of more than 1 year, the kiln skin is hung quickly in the firing zone, the thickness of the kiln skin is uniform and stable, the refractory bricks have no large flaking phenomenon, and there is no flaking phenomenon of refractory bricks when the kiln is stopped. The temperature of the kiln barrel is low, and the heat energy less loss.

Features

Good corrosion resistance, no alkali cracking, loosening and other phenomena during use.

The kiln skin is formed quickly, and the kiln skin is stable and does not fall off.

Good thermal shock resistance can improve the tolerance to temperature fluctuations of cement kilns.

Low thermal conductivity, lower the surface temperature of the rotary kiln shell, and significant energy saving effect

Application

Magnesia hercynite brick widely used in various cement rotary kilns.

Productive Process

1.Raw material quality control including physical and chemical testing.           
2.Crushing and grinding of bulk raw materials.
3. According to customer data sheet required to mixing Raw Material.
Pressing or shaping the green brick depend on different raw material and brick shape.
4.Dry the bricks at dryer kiln.
5.Put the bricks into the tunnel kiln to burning by higher temp from 1300-1800 deg.
6.The quality control department will inspect the finished refractory bricks random.
