furnace lining light weight jm26 Lightweight mullite refractory b kiln thermal fireproof silicon mullite insulating bric
Lightweight mullite refractory 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 chomical demands.
Lightweight mullite refractory bricks for special ceramic sintering furnace lining ccording to the different use of temperature production of multiple grades of mullite lightweight insulation brick is divided into WAM23 / WAM26 / WAM28, the use of temperature range from 1100C-1650C, the ratio of each product is specially designed to meet the different thermal and Physical requirements.

Performances:
1. Low heat conductivity, with good thermal insulation effect
2. Low hot melting, due to low heat conductivity, it accumulates little heat to get obvious energy-saving in intermittent operation.
3. Low impurity content and low content of iron oxide & alkali metal oxide realize high refractoriness. High Al2O3 content makes it keep good performance under reducing atmosphere.
4. High thermal compressive strength
5. Accurate size increases construction speed, decreases fire clay usage, ensures strength and stability of masonry, prolongs the life span of lining.
6. It can be processed into special shapes to reduce brickwork amount and paving seam.
Applications
Lightweight mullite refractory bricks can be used in high temperature kiln lining. Currently, it is widely used roof of hot-blast furnace, body and bottom of blast furnace, regenerative chamber of glass melting furnace, ceramic kiln, blind angle furnace lining of petroleum cracking system, shuttle kiln, roller kiln, linings of glass and petrochemical engineering furnaces.
In addition, in order to meet the production requirements of more clients and kilns, KERUI develops new products of different textures and shapes on the basis of originals, such as poly-light mullite brick tile, poly-light corundum brick, poly-light silicon brick, fire clay insulating brick, etc.
Generally suitable for thermal surface refractory lining or other refractory back lining insulation layer.
Refractory lining or thermal insulation for industrial furnaces in petroleum or chemical industries, such as ethylene cracking furnaces, tubular furnaces, reforming furnaces for synthetic ammonia, gas generators and high temperature shuttle kilns.
Tunnel kiln, push board kiln, roller kiln, wood kiln refractory lining material for industrial and household ceramics.
