High alumina refractory brick is widely used in industrial kiln mansonry, there are important connection between the amount of kiln high alumina refractory brick and size dimensions. There are many standard sizes if high alumina refractory brick, can be used in steel making, iron making, building materials, chemical engineering and industrial thermal equipment of many several fields.
Generally speaking, referring to the high alumina refractory standard sizes, usually refers to the T3 standard straight brick type, high alumina fire brick standard size is 230×114×65mm, However, the standard dimensions and specifications of high-alumina firebrick are various, which can be divided into standard size brick, side thick wedge brick, vertical thick wedge brick, vertical wide wedge brick and skew brick according to its shape.
High alumina refractory brick in the using process, usually need cutting work to satisfy different structure kiln lining construction, the deviation value of high alumina refractory brick is:
- length direction ±lmm, width(hright) direction ±
- thickness direction±5mm, the maximum allowable value for bending in the direction of length is 3mm.
- The maximum allowable value of distortion is 1.5mm, and the maximum allowable value of burning degree is 4mm.
- The maximum allowable value of Angle deviation within cutting 200mm is + / – 1mm.
