Clay refractory bricks for folding hot blast stove
Clay bricks for hot blast stoves are made of refractory clay and used to build clay bricks for blast furnaces. Clay bricks for hot blast stoves are used in hot blast stoves, regenerators and partition walls. Clay bricks for hot blast stoves require good thermal shock resistance, high load softening temperature and low creep.
China Metallurgical Standards (YB/T 5107-1993) classifies clay refractory bricks for hot blast stoves into three grades: RN-42, RN-40 and RN-36 according to physical and chemical indicators.
The physical and chemical indicators and allowable deviations of dimensions are as follows:
(1) When the spall width is not greater than 0.25mm, the length is not limited;
(2) When the spall width is 0.26~0.50mm, the length is not more than 30mm;
(3) When the spall width is greater than 0.50mm, it is unqualified.
Large clay refractory bricks for folding glass kiln
Large-scale clay refractory bricks for glass kilns are clay refractory bricks with a unit weight of not less than 50kg for masonry glass kilns. China Metallurgical Standard (YB/T 5108-1993) stipulates the physical and chemical indexes, allowable size deviation and appearance of large clay refractory bricks for glass kilns. This standard also makes the following provisions for the section cracking of bricks:
The cross-section of the brick is cracked:
1) Bricks with length ≤ 400mm: when the spall width is 0.26~0.50mm, the length is not more than 40mm; when the spall width is 0.51~lmm, the length is not more than 25mm.
2) Bricks with a length> 400mm: the spall width is 0.26, and the length is not more than 80mm when the spall width is 0.50mm; when the spall width is 0.51~1mm, the length is not more than 50mm.
For cracks with a spall width of less than 0.25mm, the length is not limited.
(3) There shall be no pores or cracks larger than 1mm on the section.
