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
