The Requirements of Refractory Material

Date:2016-12-07 17:10 | From:Zhengzhou Sunrise Refractory | Author:admin
Refractory material used for all kinds of high temperature equipment, it is the high temperature condition of the physical and chemical erosion and mechanical damage, so the performance of

refractory material shall meet the following requirements:

1. High refractoriness. Modern metallurgical furnace and other industrial kiln‘s heating temperature are generally between 1000 ~ 1800 ℃. Fire clay insulation brick should have no easy to melt

performance under the action of high temperature.





2. High temperature structural strength is large. Refractory materials should not only have high melting temperature, but also should not happen softening deformation and collapse under the

stove masonry load or other mechanical shock.

3. Thermal stability is good. Metallurgical furnace and other industrial kiln are in operation, due to temperature shock caused by uneven temperature of each part of refractory material, masonry

internal stress and make the material fissile and peeling. Therefore, refractory materials should have the ability to resist the damage.

4. Slag resistance ability is strong. Refractory material in use process, often by high temperature furnace slag, metal and chemical erosion of furnace dust. Therefore, must have the ability to resist

erosion of refractory material.

5. High temperature volume is stable. Refractory materials at high temperature for a long time use, bricky system internal can produce volume shrinkage or expansion, causes the damage of

refractory masonry.
