Q:How to make refractory bricks and boiler wall adhesion more firm?
Suggest that you use fire brick to increase the length of brick or pull the amount of turn, and use high temperature mortar masonry
Q:What are the lining structures of lime rotary kilns and what are the requirements for refractories?
The rotary kiln lining structure of rotary kiln and requirements on refractories calcining active lime according to the general output is divided into Nissan 300t, 400 t, 600 t, 800 t, 1000 t, 12000 t of kiln type, calcining zone temperature at 1350 degrees celsius. The kiln is divided into a discharge end, a cooling zone, a burning zone, a preheating zone and a feeding end, and the temperature of each section of the kiln ranges from 1000 DEG C to 1350 DEG C, and the requirements for refractory materials are different. The kiln refractory materials not only to withstand the high temperature impact, but also need to bear the material erosion, kiln rotation stress produced, so not only on the physico-chemical properties of refractory materials have strict requirements, but also for the construction of brick should be strictly.
Q:What does refractory consist of
According to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.
Q:How to reduce the harm caused by two times mullite in high alumina refractory material
Prolong the sintering time and adjust the aluminum content of the high alumina brick.
Q:What are the specifications for bricks?
Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels. Clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete. In order to improve the shortcomings of ordinary clay bricks, such as small, self important and waste of soil, they are developing in the direction of light weight, high strength, hollow and big blocks.
Q:What is the standard classification of high alumina bricks or high alumina bricks?
High alumina brick is a kind of refractory material in refractory brick products. It is made of refractory clay or other refractory material. It belongs to the product of Si Al System
Q:How many cubic bricks does a high alumina brick have?
Different content of aluminum, different proportion, weight is not the same. General grade T3 standard brick, 4.3~4.5kg, aluminium content 75. T3 size 230*114*65mm.
Q:What is fireproof concrete?
A series of concrete with fire resistance and heat resistance is made of Portland cement series as cementing material and heat-resistant material as aggregate. Silicate fireproof heat-resistant concrete with Portland slag cement, Portland cement and water glass as cementing material, broken clay brick, clay, cement clinker, broken high alumina brick as aggregate.
Q:What are the categories of bricks?
In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.
Q:Use of high alumina refractory bricks?
High alumina refractory brick in Al2O3 more, close to neutral refractory material, can resist acid slag and alkaline slag erosion, because it contains SiO2, so alkaline slag ability than acid resistance slag ability less.It is widely used in building blast furnace, hot blast furnace, furnace top, blast furnace, reverberatory furnace and rotary kiln lining. In addition, high alumina bricks are widely used as furnace regenerative checker, pouring system for plug nozzle, etc..
