White mullite lightweight refractory fire brick with good thermal storage
1. Description
high heat resistant insulation bricks are made from good quality
and superpure raw materials, with strictly classified fillings
according to their grades. These fillings can form a uniform pore
structure after burnt during the process of manufacture. Each grade
of products has unique design to meet different thermal, physical
and chemical demands.
The total weight of the furnace body and walls thickness can be
reduced effectively,thermal efficiency and working condition can be
improved,energy consumption can be lowered,produtivity and
significant economic results can be achieved.
It has great features including low thermal conductivity, High heat resistant and durability, Excellent resistance to thermal shock, Excellent construction strength and structural integrity, etc, which enable its capability of dealing with erosive and abrasive environments. IFB can either deliver big energy savings for many industrials or offer superior structural performance in load bearing applications or/and in conditions where mechanical abrasion exists or flow of hot gases is severe.
