Specifications for High Alumina Brick for Hot-Blast Stove

Characteristic:
1.High-temperature resistance
2.Lower creep rate
3.High strength
4.Good thermal shock resistance

This product is made by superfine calcined bauxite, additive and high-quality combined clay. This product has good performances of hot flue scouring resistance and corrosion resistance. Its apparent porosity is lower,strength is high and its creep rate is lower, so it means that this product can well keep stability under the load and high temperature.

Q:What is the standard classification of high alumina bricks and high alumina bricks?: Refractory brick is non-metallic materials can be classified according to a kind of inorganic material, high aluminum brick, clay brick, magnesia brick, corundum brick, mullite bricks, silicon carbide materials such as brick, high alumina brick is used as a relatively wide range of products in accordance with the refractory brick high alumina refractory materials by high aluminum brick is generally divided into Al2O3 content three: I - II - >75% Al2O3 content; the content of Al2O3 is 60 ~ 75%; III - Al2O3 content from 48 to 60%.

Q:How does the physicochemical index change when the high alumina brick is used at high temperature?: When the high alumina brick is used at high temperature, the physical and chemical indexes and other constants will not change if the temperature is in the physical and chemical indexes and the softening temperature of the load.

Q:What's the price of high alumina refractory bricks?: The price of high alumina refractory bricks varies greatly according to the content of AL2O3.

Q:What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?: Quality requirements for aluminium bricks of different grade. 2, high aluminum powder and high alumina aggregate and other materials of reasonable proportion, to reach the production requirements.

Q:What is the content of free silica in the refractory bricks of high alumina bricks?: Refractory powders are not rich in free silica in varying degrees

Q:What are the reasons for the spalling of refractory bricks in the production of lime kiln?: In the course of the production of lime kiln, the local block of refractory brick is a very dangerous signal. It is suggested that you stop the kiln to prevent the collapse of a large area. Lime kiln is the main equipment for the production of limestone kiln and rotary kiln is two, with the growth of calcium carbide lime kiln industry, iron and steel industry, the construction industry to the amount of limestone has become the main production equipment, and refractory bricks became the heart of lime kiln.

Q:How can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?: Top burning type hot blast stoveIt means that the burner is installed on the top of the hot blast furnace of the iron making equipment, and it does not need a special combustion chamber in the vault space. It is also called a non combustion chamber type hot blast stove.

Q:High alumina brick 80 with which high aluminum cement?: Which kind should be chosen should be determined according to the conditions of use, life expectancy and cost control. By the way, the quality of masonry is also very influential.

Q:Does the chimney have high acid resistance?: The chimney particles and gases, mostly coal tar products, material acidic, therefore, take good acid resistance, acid proof brick, Grouts also used potassium silicate clay acid is preferred.

Q:How are the high alumina bricks fired?: According to the quality requirements of different grades of high alumina brick, choose different grades of bauxite raw materials, it is conducive to rational use, fine materials, fine distribution, as far as possible not to use mixed grade severe raw materials. The quality of the clinker depends on the calcination temperature, calcination temperature, sintering temperature should be generally reached or slightly higher than that of alumina clinker sintering, to ensure the full and possible high volume density, and the two secondary Mullitization and sintering shrinkage effect in calcination process. Lightweight high alumina brick, also known as high aluminum insulation brick (high-aluminium heat insulating brick). A lightweight refractory consisting of mullite and glass phases or corundum in excess of 48%. The volume density is 0.4 ~ 1.35g/cm3. The porosity is 66% ~ 73%, and the compressive strength is 1 ~ 8MPa. Better thermal shock resistance.
