The following are the detailed requirements you need to provide when customizing high-alumina bricks:
I. Product specification requirements
(1) Size requirements
Standard size: Please make clear whether standard-sized high-alumina bricks are needed, such as common straight bricks (L×W×H, for example, 230mm×114mm×65mm), arch bricks (L×W×H/h, for example, 230mm×114mm×65mm/55mm) or wedge bricks (L× w× 55mm).
Customized size: If there are special size requirements, the length, width and height of the brick and the detailed size parameters of special shapes (such as special-shaped bricks, such as runner brick, cast steel bricks, round bricks, etc.) should be provided in detail, including the length, width, height, angle and radian of each part. It is best to provide clear drawings with dimensional accuracy requirements (such as ±0.5mm, etc.).
(2) Shape requirements
In addition to the common straight, arch and wedge bricks, if you need special-shaped high-alumina bricks, such as special-shaped bricks used in specific furnace parts, you need to clearly describe the shape characteristics, such as whether they are round, square, polygonal, with holes, with protrusions or grooves and other special structures, as well as the specific dimensions and positions of these special structures.
II. Chemical Composition Requirements
Alumina content: The alumina (AL₂O₃) content of high-alumina brick is one of the key factors affecting its performance. We provide high alumina bricks with different alumina content ranges, such as 30%-85% and other grades. Please specify the required alumina content range or specific value according to your use scenario and fire resistance requirements.
Restrictions on other chemical components: If there are any special requirements for other chemical components such as iron content (Fe₂O₃), for example, the iron content should not exceed a certain value (such as ≤2.0%), please indicate it.
III. Physical performance requirements
Refractory: Refractory is a performance index to measure the non-melting of high-alumina bricks in high temperature environment. We have products with different fire resistance grades, such as SK-32 (fire resistance 1710°C) and SK-34 (fire resistance 1750°C). Please choose the appropriate fire resistance grade according to the working temperature of your furnace.
Load softening temperature: under the combined action of high temperature and pressure, the ability of high-alumina brick to maintain shape and performance is measured by load softening temperature. For example, the load softening temperature of SK-32 (2 kg/cm, t) ≥ 1350 C, SK-34 ≥ 1400 C, etc. Please specify the required load softening temperature range according to the actual use conditions.
Apparent porosity: Apparent porosity affects the corrosion resistance and thermal insulation performance of high alumina brick. Generally, the apparent porosity of our high-alumina bricks is within a certain range, such as ≤22%. If there are stricter requirements on apparent porosity, please let us know the specific value.
Volume density: Volume density reflects the density of high-alumina brick, which is related to its strength, wear resistance and other properties. For example, the bulk density of SK-32 is 2.0 ~ 2.1g/cm, and that of SK-34 is 2.1 ~ 2.2g/cm. Please specify the range of bulk density as required.
Compressive strength at room temperature: compressive strength at room temperature is a measure of the ability of high-alumina brick to resist pressure at room temperature. For example, the room temperature compressive strength of SK-32 is ≥ 250 kg/cm, and SK-34 is ≥ 350 kg/cm. Please determine the required compressive strength at room temperature according to the possible load in actual use.
Thermal expansion rate: the thermal expansion rate affects the dimensional stability of high-alumina bricks when the temperature changes. The thermal expansion rate of our products is within a certain range, such as 0.4 ~ 0.7% at 1000 C. If there are special requirements for thermal expansion rate, please provide specific numerical range.
Thermal shock resistance: Thermal shock resistance is the ability of high-alumina brick not to crack and peel off when the temperature changes sharply. If there are usage scenarios such as rapid temperature rise and fall, it is necessary to specify the requirements for thermal shock resistance, such as the requirements for the degree of damage after being subjected to thermal shock tests in a certain temperature range and times.
IV. Requirements for use environment
Temperature range: Please specify the maximum working temperature, minimum working temperature and temperature fluctuation range that the high-alumina brick will use. For example, whether it is in a high temperature environment for a long time (such as above 1500°C), or whether there are frequent temperature rises and falls (such as cooling from room temperature to 1200°C).
Atmosphere environment: The atmosphere in the use environment has an important influence on the performance of high-alumina bricks. Please let us know whether it is an oxidizing atmosphere, a reducing atmosphere or a neutral atmosphere, and whether there are corrosive gases (such as acid gas, alkaline gas, etc.), so that we can choose the appropriate brick type and formula.
Contact medium: whether the high-alumina brick will contact with specific substances during use, such as molten metal (such as molten steel, molten aluminum, etc.), molten glass, chemical reagents, etc. If yes, please specify the type and nature of contact medium so that we can evaluate whether the corrosion resistance of high-alumina brick meets the requirements.
V. Quantity requirements
Please specify the specific quantity of high-alumina bricks required, including the quantity of each specification and model. If the quantity is large, a rough procurement plan can be provided, such as the time and quantity arrangement of batch procurement.
VI. Other Special Requirements
Appearance requirements: If there are any special requirements for the appearance color, surface smoothness, cracks and missing corners of high-alumina bricks, please specify them in detail. For example, it is required that the color of the brick is uniform, there is no obvious crack on the surface, and the length of the missing corner does not exceed a certain value.
Packaging requirements: Although we have standard packaging methods (such as pallet packaging, fixing with PET tape and covering with plastic film), if you have special packaging requirements, such as special packaging measures such as moistureproof, shockproof and antistatic, or specific packaging identification requirements, please let us know.
Delivery time requirement: Please let us know the expected delivery time so that we can arrange the production plan reasonably. We will try our best to meet your delivery requirements, but we should also consider factors such as actual production capacity and raw material supply.
Quality standard requirements: We produce high-alumina bricks according to KS, JIS, ASTM, ASME, AMS, DIN and other quality standards. If you have specific quality standards, if you need to meet the specific standards of a country or industry, please clearly point out.
In order to ensure that the customized high-alumina brick fully meets your needs, it is recommended that you provide the customized requirements as detailed and accurate as possible.
