Arch brick for the cylindrical inner lining of a rotary drum furnace and rotary drum furnace

摘要

The brick has a planar-shaped separation surface running at an angle (alpha) greater than 20 degrees with respect to a base surface (AG asterisk). Trapezoidal shaped brick sections (10, 12) include two outer surfaces (RS2), which are located opposite to one another. The outer surfaces located opposite to one another are equal in size, where the arch brick conforms to DIN1082-4 standard and stretches along the separation surface, which stretches from the base surface to trapezoidal-shaped front surfaces (TS1 asterisk, TS2) or towards another base surface (IG asterisk).
