What are the acceptance items of Refrakter tuğlalar?

After the refractory bricks enter the factory, acceptance and selection should be carried out, and unqualified bricks (such as cracks and corner drops) should be removed. During acceptance, it is mainly to check whether the chemical composition, specification and shape of the refractory brick meet the requirements. It would be better to conduct tests such as fire resistance, rapid cold and rapid heat resistance, and compressive strength. The size of refractory bricks requires an error of no more than 3mm. If the error is too large, it will bring certain difficulties to the bricklaying, and the quality of the inlay is also difficult to guarantee.
