Brief Introduction
Curved refractory bricks are special refractory materials designed for curved structures of high-temperature industrial equipment. They have high temperature resistance, corrosion resistance and structural adaptability.
Material And Classification
➤Material type
Mainly divided into high-alumina (alumina content ≥50%, refractoriness ≥1770℃), clay, siliceous, etc., among which high-alumina has become the mainstream due to its strong slag resistance and long life.
➤Specification parameters
The common sizes are 300×150×75mm and 350×175×80mm. The radius of the arc is selected according to the actual needs of the kiln. The larger the radius, the stronger the load-bearing capacity.
