Product Description:

Description

  1. CT firebricks are made from high-purity refractory clays, temperature of use ranging from 1100 oC to 1700 oC, each grade is formulated to meet specific thermal and physical requirements.

  2. With graduated additions of alumina for higher temperature products

  3. Carefully grade d organic filler

  4. The organic filler burns out during manufacture to give a uniform, control pore structure.

Features

  1. low thermal conductive, low heat storage

  2. purity

  3. good thermal insulation, enable the use of thin-walled constructions

  4. the good alumina contents confer good refractoriness

  5. iow iron and alkali fluxcontent contributes to their stability to reducing atmosphere

  6. these can be machined to special shapes, incurring fewer sections and joints

Typical Application

  1. Recommended for use as primary hot face refractory lining or as back-up insulation behind other refractories in furnaces, kiln, flues, heaters, regenerators, stress relieving furnaces,etc

Q:What materials are used for roof insulation?
The other one is inorganic insulation materials, such as Portland, rare earth insulation, the thickness should be 5 cm or more, up to the high cost of auxiliary materials of construction, to reinforce, new inorganic insulation material, the material thickness, on the line of 2-3 cm, direct smear on the top of the house, without auxiliary material, than the price of wool, high aluminum silicate cotton.
Q:The cloth blowing is not uniform on the lime kiln refractory brick is damaged it
Lining 1 yuan to prevent direct damage to the Sindh kiln high temperature flame or air, to protect the kiln carcass; 2, to prevent harmful substances (CO, SO2) erosion of the kiln body; 3, to prevent corrosion, material flow on the kiln body; 4, reduce the kiln temperature, kiln body to prevent oxidation 5, has the function of corrosion; thermal insulation; 6, to improve the coating performance.
Q:Which thermal shock stability of clay brick and high alumina brick is good?
The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized hot blast stoves.Thermal shock stability is much better than clay brick.
Q:Does the chimney have high acid resistance?
The acid resistant bricks used for chimney are usually made of custom-made trapezoidal acid proof bricks, and the physical and chemical indexes of acid resistant bricks need to be confirmed according to the chimney's actual emission. At this point, you can consult our kerei refractories.
Q:Which is faster for heat transfer between corundum bricks or high alumina bricks?
75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.
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 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 grades of high alumina bricks?
High alumina brick according to the aluminum content is generally divided into: super high alumina brick, a high aluminum brick, two high alumina brick, three high alumina brick
Q:What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?
The brick Pei boring and time. 6, Pei brick kiln installed between the brick and the brick Pei order, Pei and kiln top, kiln wall gap etc.. 7, high alumina brick kiln plan, and the lack of edges and corners of the scene should be avoided.
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..
