Product Description

YUFENGREC^® Fireclay Brick & High Alumina Brick  are made of high-grade Flint Clay,Chamotte ,High Alumina Bauxite  with alumina content from 36% to 85% , producing by drying pressing and high fired .

YUFENGREC^® Mullite Bricks based on synthetic fused Mullite  and sintered Mullite  shaped by high pressure presses or casting process as per different applications  and fired in high temperature  furnaces  . Mullite Brick features with good thermal properties and adequate erosion and corrosion  resistance  ,which is widely used to hot end of regenerative  chambers  of glass melter , superstructure of the furnace  .

YUFENGREC^® Andalusite Bricks is made by  non-contaminated andalusite from natural sources as the raw material ,shaped by hydraulic high pressure presses .During the production processing, the bricks is strictly controlled with the reasonable particle size of the raw materials ,adopt new process , multi-stage ingredients, matrix homogenization, and determines the best calcination temperature  etc.,  to achieve  high quality level  to  meet the use of different parts of blast furnace and hot blast stove and different working environments
