Application:
They are mainly used in mould cast steel ingot of casting steel industry.
In order to ensure that we can provide you with customized nozzle bricks that meet your needs, the following is a detailed description of customization requirements, please read it carefully and provide relevant information.
I. Product specification requirements
(1) Size parameters
Please specify the outer diameter, inner diameter and height of the nozzle brick. For example, the outer diameter [X] mm, the inner diameter [X] mm and the height [X] mm. The accuracy requirements of dimensions should also be informed, and if high-precision machining is needed, what is the accuracy range (such as 0.5 mm, etc.).
If the nozzle brick has a special shape design, such as the arc design of the upper mouth, please provide detailed shape description or drawings, including the radius and angle of the arc and other related parameters.
(2) Aperture and pass
It is very important to specify the pore size of nozzle brick for controlling molten steel flow. For example, the aperture is [X] mm.
Determine whether the pass is round, oval or other special shapes, and provide the corresponding shape and size data.
II. Material composition requirements
(1) Alumina content
The alumina (Al₂O₃) content of nozzle brick can be selected between 40% and 75%. Different alumina content will affect the fire resistance and corrosion resistance of nozzle brick. Please specify the required alumina content range according to your actual use scenarios and process requirements. For example, if it is used for pouring high-temperature molten steel and requires extremely high fire resistance, it may be necessary to choose nozzle bricks with alumina content of 70%-75%.
(2) Requirements for other components
If there are special requirements for other chemical components of nozzle brick, such as limiting the content of some impurity components, please list them in detail. For example, it is required that the content of silicon dioxide (SiO₂) in the nozzle brick should not exceed [X]% to avoid adverse effects on the quality of molten steel.
III. Performance requirements
(1) Fire resistance
Specify the fire-resistant temperature range that the nozzle brick needs to reach. For example, it is required that the fire resistance is not lower than [X]℃ to ensure that melting or deformation will not occur during high-temperature molten steel pouring.
(2) Thermal shock resistance
The possible temperature changes of nozzle brick in use are explained, so that we can choose suitable materials and production technology to improve its thermal shock resistance. For example, the nozzle brick needs to withstand the rapid change of molten steel temperature from room temperature to high temperature frequently in the process of use, and it is required to resist thermal shock for more than [X] times.
(3) Wear resistance and erosion resistance
According to the composition of molten steel and pouring process, the wear resistance and corrosion resistance grade of nozzle brick are defined. For example, it is required that the surface wear of nozzle brick should not exceed [X] mm/hour under the scouring of high-temperature molten steel; When contacting with oxide inclusions and other substances in molten steel, the corrosion resistance can reach [X] level (refer to the relevant corrosion resistance standards of refractories).
IV. Requirements for use environment
(1) Composition and temperature of molten steel
Provide the approximate composition range of molten steel, such as the range of main elements such as carbon content, silicon content and manganese content. Different molten steel compositions may have different chemical erosion effects on nozzle bricks. At the same time, the pouring temperature range of molten steel is defined, so that we can optimize the material formula and structural design of nozzle brick and make it have good performance stability in this temperature range.
(2) pouring process parameters
The technological parameters such as pouring speed and pouring time of molten steel are explained. For example, the pouring speed is [X] tons/hour, and the single pouring time is about [X] hours. These parameters will affect the service life and performance requirements of nozzle brick, and help us to customize more suitable nozzle brick for you.
V. Other requirements
(1) Appearance requirements
If you have any special requirements on the appearance of nozzle brick, such as surface smoothness and color, please indicate. For example, the surface roughness of nozzle brick is required to reach [X] level, and the color is white or close to white, so as to meet the visual requirements of production site or facilitate the observation of molten steel flow.
(2) Packaging and transportation requirements
Specify the packaging method of nozzle brick, such as whether special protective packaging is needed to prevent damage during transportation. At the same time, inform the mode of transportation (such as road transportation, railway transportation, sea transportation, etc.) so that we can choose appropriate packaging materials and packaging structures to ensure the safe delivery of products.
(3) Delivery time requirements
Make clear your expected delivery time. We will arrange the production schedule reasonably according to your delivery time requirements to ensure the timely delivery of products. For example, delivery is required within [X] days after the contract is signed.
(4) Quality inspection and acceptance criteria
Provide the quality inspection standards and acceptance standards you rely on, such as international standards (such as KS, JIS, ASTM, etc.), national standards or enterprise standards. We will carry out production and quality inspection in strict accordance with the standards provided by you to ensure that the delivered products meet your requirements.
In order to better meet your customization needs, it is recommended that you provide detailed product drawings, technical specification documents or samples (if any). Our professional technicians will make a personalized customized plan for the nozzle brick according to the information provided by you, and keep close communication with you to ensure that the products meet your expectations.
