Characteristics
sic refractory fire bricks have the following Features:
oxidating resistance: it suits for the oxidating atmosphere,and the sic refractory fire bricks' life is up to 500-1000times in the proper operation and sintering.
modulus of rupture and compressive strength resistance: sic refractory fire bricks can be used on one side for long time without bending.
cold and hot resistance without crack
bulk density and surface flatness without dregs falling.
Using temperature: sic refractory fire bricks can be used from 800°C-1650°C.
Deformation:compare with other factory sic refractory fire bricks(same size),our products have no warpage after long time using,so that it can save the energy and increase the volume of your kiln,therefore sic refractory fire bricks can increase your efficiency and save your economy.We can supply you the samples and you can test it.
High bearing capacity
Energy saving
Burning time is short
Better thermal shock performance
Good corrosion resistance
There is no contraction
The highest use temperature is 1650 ℃
