    Furnace Lining Thermal Fireproof Mullite Bricks Heat Insulating

    Product Introduction

    Lightweight mullite insulating bricks are made of high-quality and high-purity refractory materials, according to the specific gravity of the product, with organic compound fillers, vacuum extrusion molding, and high-temperature sintering to synthesize lightweight mullite products. With its light weight and excellent thermal insulation performance, lightweight mullite insulating bricks are widely used in the hot surface refractory lining or insulation layer of a variety of thermal equipment, creating conditions for improving the energy efficiency of the equipment.
    High alumina refractories with mullite as the main crystal phase generally have an alumina content between 50% and 75%. The refractory temperature of mullite lightweight brick can reach above 1790℃. The starting temperature of load softening is 1600-1700℃. Pressure resistance at room temperature is slightly 70-260MPa. Good thermal shock resistance. There are two types of sintered mullite insulating bricks and fused mullite insulating bricks.

    Product features

    Low thermal conductivity; Excellent thermal insulation effect.

    Low heat capacity; due to low heat rate, AKB series insulating brick accumulation little heat, in intermittent operation and obvious effect of energy saving.

    Low impurity content: having a very low alkali metal ans iron oxide content, therefore high refractoriness, high aluminum content in the reducing atmosphere still maintain good performance. Hot compressive strength.

    Dimensions: accelerate building speed, accurate reduction refractory slurry usage, to ensure the masonry strength and stability, thereby prolonging lining life.


    Product Applications:

    Can be used as heat surface refractory lining or other refractory insulation backing layer, used in petroleum, chemical industry, ethylene cracking furnace tube type heating furnace, furnace, ammonia synthesis gas furnace, high temperature shuttle kiln and other industrial furnace refractory lining insulation materials.
