Refractory brick/Fire proof brick

High alumina bricks for Ladle/Steel-making

LZ-75,LZ-65,LZ-55 High Alumina Brick

Features:

1) high tempreture endurable 2) good thermal shock resistance 3) good thermal insulation performance

It is one of our main products whose main mineral is mullite and corundum phases, with excellent high-temperature physical properties and chemical corrosion resistance, widely used in any parts of blast furnace with good work-ability. It has been used in large volume blast furnace with a good result.
