various of performance analysis of Alumina bricks

Mainly composed of special level bauxite chamotte as starting material and assisted with special additives, the brick are processed by moulding under high pressure and sintering under high temperature, with features like large heat accumulating capacity and small creep rate. They are avail able for blast hot stove matched of middle and small blast furnace.

Introduction to the making craft of high alumina brick

Alumina bricks can be divided refractory fiber felt according to the different attributes are many ways to apply as a manufacturer for the appropriate distribution of our product quality and

technology and other high alumina bricks, first alumina brick porosity What have porosity?
All percentage of the total volume of pore volume alumina brick station is porosity. Meanwhile alumina bricks have permeability, air permeability per unit time is the amount of

gas by the size of the China refractory material refractory bricks.

Production technology of high alumina brick and clinker clay brick more similar, the difference is that the ingredients in the clinker ratio is higher, can be as high as 90 ~

95%, before breaking the clinker grading sorting and screening in addition to iron, firing temperature is higher, such as Ⅰ, Ⅱhigh alumina refractory brick with tunnel kiln

firing when the general is 1500 ~ 1600 ℃.

Chinese production practice zirconium sizing nozzle has proved that high alumina clinker strictly choose grading, and hierarchical storage before crushing, bauxite clinker and clay together fine

grinding method, to improve the quality of products.


Tips manufacturers, high ladle gunning mix alumina brick thermal expansion and contraction with temperature changes due to expansion and contraction of the reverse. Anti rapid thermal quench

performance is alumina brick thermal shock resistance and chipping resistance. Alumina bricks in long-term use due to impurities affect tissue invasive exfoliation.China

refractory material atmosphere and other factors. Therefore, high alumina brick refractoriness with stability.
