GMK Anorthite Insulating Firebricks are made by blending clay and plaster, when fired, the lime from the plaster reacts with the clay to form anorthite, the plaster decomposes, losing about 70% of its weight, leaving micro porosity and very low thermal conductivity of finished brick.
GMK Anorthite Insulating Firebricks are manufactured in compliance with international industry standard, which is a kind high efficiency, energy saving, environment friendly refractory insulating products.
High Insulating Values: The low density & low thermal conductivity value of GMK anorthite insulating firebrick make possible thinner furnace wall, improved efficiency and lower operation costs.
Good Reheating Linear Change: The tiny reheating linear change value of GMK anorthite insulating firebrick means good high temperature volume stability, assured furnace integrity lining, keeping furnace high productive.
Low Heat Storage: Low heat storage means reduced fuel costs and faster heat-ups in cyclically operated heating equipment.
High Purity: GMK anorthite insulating firebrick are low in impurity such as iron, which can be adversely affect refractory performance in many applications. They are used in many furnaces with controlled or hydrogen-rich atmospheres.
Accurate Dimensions: GMK anorthite insulating firebrick are machined grind into precise dimensions, can be laid quickly and easily, and the result is a stronger, tighter refractory lining resulting in less heat loss through the joints.
Ideal products used as a primary hot face refractory lining or as back-up insulation behind other refractories in furnaces.
Widely used in industrial furnaces in petrochemical, ceramics, glass, metallurgy, heat treatment, non-ferrous metals and other industries. Typical furnace such as ethylene cracking furnace, hydrogen production furnace, one-stage reforming furnace, heating furnace, heat treatment furnace, glass tank regenerator, blast furnace, hot blast stove, roller kiln and other thermal equipment.
