High Quality 70% High Alumina High Temperature Yellow Refractory Anchor Brick For Industrial Furnace
Anchor refractory brick is a kind of refractory brick for industrial furnace top construction. anchor fire brick includes cylinder formed by suspended end and anchoring body, and there is grooves distributing on the bricks body. Its refractoriness is over 1700℃. anchor refractory block can be used in all kinds of industrial kilns. and anchor firebrick is widely used for the roof and walls of the heating furnace with features of high strength, good mechanical performance and good anti-strip performance.
Anchor blocks include suspended bricks and perforaled tiles with forming processes of two types of mechanical pressing and pouring forming. according to customers’ operating requirements, choose the basically the same structure materials with castable refractory of furnace lining through firing in the high temperature. anchor block has high strength, good erosion resistance property and good spalling resistance, which have the basically the same expansion with furnace lining refractory castable.
.High refractoriness,
.High strength,
.Good spalling resistance,
.Low thermal conductivity,
.Good mechanical performance,
.Excellent thermal shock resistance.
Anchor brick is made of high quality of bauxite as the raw materials containing 48~80% alumina content and formed through pressing and firing in the high temperature. anchor blocks are mainly used in thermal furnaces such as heating furnace, coal chemical industry kiln and electric furnace top.
