THE FEATURES OF HIGH ALUMINA BRICK FOR BF

High Alumina brick for BF selects the high quality clinker bauxite with low Fe2O3,TiO2 content.

High Alumina brick for BF has high refractoriness under load, stable volume under high temperature and good thermal shock resistance.

THE FEATURES OF HIGH ALUMINA INSULATION BRICK

High-Alumina insulation brick is a kind of insulation material adopting organic matter as ignition loss substance.

High-Alumina insulation brick has small volume density, good insulation effect,high mechanical intensity, small thermal conductivity and long service life.For various industrial kilns & furnance.

High-Alumina insulation brick is a kind of sessential refractory for energy saving and temperati\ure preservation.

High-Alumina insulating clay brick can be used auxiliary with other lining materials for the coke oven to have better insulation effect and save energy.

Q: What is the difference between corundum and high alumina??: The main components of high alumina brick are high alumina bauxite, mullite and partial corundum sand.

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 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's the difference between a well type annealing furnace and a box type annealing furnace?: Box annealing furnace application: mainly used for quenching, normalizing, annealing and other conventional heat treatment equipment for steel parts. Features: 1, electric loading, high productivity, heat treatment is especially suitable for small and medium-sized parts, such as 30%, uniform temperature, intelligent digital display meter PID (pictured) automatic temperature control, high precision; 2, electric discharge loading convenient, as good; 3, door and seal the oven body is sealed automatically, without manual seal; 4, equipped with electric interlock protection device, and can prevent the fault accident due to the error. Bell type annealing furnace four bell type annealing furnace bell type annealing furnace is mainly used for annealing sheet metal in natural atmosphere and normalizing treatment of steel parts. 1, special steel, precision alloy large all fiber trolley type resistance furnace, strip, wire bright annealing. 2 、 annealing of special steel casting and forging. 3. Annealing of silicon steel sheet. 4, metal and non metal powder sintering pieces etc..

Q: Density of high alumina bricks: The density of high alumina bricks is determined according to the price. The average density is between 2.3-2.5g/cm3. The higher the density, the higher the price, the higher the aluminum bricks are in the industry. More than 2.4 are required.

Q: What is the difference between T3 refractory bricks and high alumina refractory bricks?: The T3 in T3 refractory bricks refers to the model indicating that the refractory brick model is T-3, and that the corresponding T-3 model is 230*114*65 (mm)

Q: How to make refractory bricks and boiler wall adhesion more firm?: If the condition, the user heat-resistant steel welding grip nails, expansion joints can not be too big.. Also to use high temperature aluminum brick, high temperature resistance, but also to extend its use cycle.

Q: What are the requirements for refractory materials in heat treatment furnace?: Refractoriness is the property of a refractory against high temperature, which means the temperature at which a refractory is softened to some extent after heating, but not its melting point. According to the degree of refractory, refractory materials can be divided into: General refractories, refractory degree is 1580 to 1770 DEG C; advanced refractories, refractory degree is 1770 to 2000 DEG C; special refractory material, refractory degree is greater than 2000 DEG C.

Q: How high can aluminum bricks expand at 80O degrees of heat?: When an object is heated, the particle moves faster and thus occupies additional space. This phenomenon is called dilation.

Q: Which thermal shock stability of clay brick and high alumina brick is good?: High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.
