High quality fire brick

. QN-JM26fire brick 1.Bending strength :1.1Mpa 2.Lower content in iron, alkaline and impurities, good high temperature properties, energy goodresistance to reduction atmosphere. 3.Homogeneous structure, light weight, high crushing strength, good insulating properties, energy saving because lower heat storage in the furnace body during cooling-heating cycles. 4.Safty application temperature:1430 Deg. Centigrate. 5.Bulk density:0.80 6.Crushing strength:2.0Mpa. High strength, good volume stability and thermal shock resistance under high temperature. 7.Less size tolerance due to grinding and shaping after sintering, this meets the requirement of construction.
