What Are The Effects of Refractory Materials?
Refractoriness refers to refractory cone sample in which there are no load cases, resistance to high
temperature function and not soften the Celsius temperature. Refractory materials is not less than 1580 ℃
refractoriness of inorganic non-metallic materials. But just to define the refractoriness cannot fully describe the
refractory materials, 1580 ℃ is not absolute. Now defined as any physical and chemical properties to allow its
use in high temperature environment is called refractory material. Refractory material is widely used in
metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, motivation and other industrial
area, etc. The dosage in metallurgy industry is the biggest, accounts for 50% ~ 60% of total output.
Although the definition of national regulation is different, for example, the international organization for
standardization (ISO) in the official publication of international standard, "refractory material, the refractoriness is
at least 1500 ℃ of nonmetallic materials or products (but do not rule out that contain a certain proportion of
metal)", but the basic concept is the same, namely the refractory material is the structure material used for high
temperature furnace, furnace thermal equipment, as well as high temperature containers and components of
materials used in industry, and can withstand the corresponding physical and chemical change and
mechanical action.
According to the refractoriness, can be divided into ordinary refractory products (1580 ~ 1770 ℃), high-grade
refractory products (1770 ~ 1770 ℃) and super refractory products (above 2000 ℃).
In metallurgy, silicate, chemical, power, petroleum, machinery manufacturing industry, refractory material is
used widely. Metallurgical industry of refractory consumption accounted for about 50 ~ 60% of the total refractory.
