China 2021 Good Quality Silica Refractory Brick - Manufacturer Universal Arc Brick Curved Fire Clay Brick – Rongsheng factory and manufacturers | Rongsheng

curved refractory brick contains Al2O3 about 30% ~ 45%, and silica content is lower than 78%. curved refractory bricks belong to the weak acid refractory materials. curved refractory block is resistant to acid slag and the erosion of acid gases, but the alkali resistance ability is a bit poor. curved refractory blocks have the characters of good thermal performance and good thermal shock resistance.

Properties of Curved Firebrick

• High refractoriness,
• Good corrosion resistance,
• Good thermal shock resistance,
• High mechanical strength,
• High-temperature creep rate is low,
• Good spalling resistance and wear resistance.
