Customized sleeve brick needs to consider the use scene, material characteristics, size requirements and cost. The following are detailed customization methods and processes:

I. Determine the use scenarios and performance requirements

Sleeve bricks are mainly used in the continuous casting process of iron and steel industry, such as converter tapping hole and steel bucket. When customizing the sleeve brick, it is necessary to define its specific application scenarios to determine the following performance requirements:

Fire resistance: the sleeve brick needs to withstand high temperature environment, and the fire resistance usually needs to reach above 1600℃.

Thermal shock resistance: when the temperature changes sharply, the sleeve brick should keep the structure stable.

Wear resistance and erosion resistance: sleeve bricks should resist the erosion of molten steel and slag.

II. Selection of materials

The main materials of sleeve brick include:

Aluminum-carbon: suitable for high temperature environment, with good corrosion resistance and wear resistance.

High alumina: the alumina content is between 40% and 75%, which has high fire resistance and good thermal shock resistance.

Clay: Low cost, suitable for some scenes with low requirements on fire resistance.

III. Determining size and shape

The size and shape of sleeve brick should be determined according to the specific use scene and process requirements:

Inner diameter: determined according to tapping time and flow demand.

Wall thickness: determined according to service life and strength requirements.

Shape: Common ones are round, square, etc. The inner hole can be straight-through or trumpet-shaped.

IV. Provision of technical specifications and drawings

In order to ensure that the sleeve brick meets the use requirements, detailed technical specifications and drawings shall be provided, including:

Chemical composition: such as alumina content.

Physical properties: such as fire resistance, thermal shock resistance, apparent porosity, etc.

Dimensional accuracy: ensure the accuracy of installation and use.

V. Selection of production process

The production technology of sleeve brick includes isostatic pressing and mechanical pressing. Isostatic pressing is suitable for integral sleeve brick, which can improve the compactness and strength of the product; Mechanical compression molding is suitable for split sleeve bricks, and the cost is relatively low.

VI. Quality inspection and testing

Customized sleeve bricks need to undergo strict quality inspection, including:

Chemical analysis: ensure that the material composition meets the requirements.

Physical performance test: such as fire resistance, thermal shock resistance, apparent porosity, etc.

Visual inspection: dimensional accuracy, surface quality, etc.

VII. Contact suppliers

Provide the above information to professional refractory suppliers, such as Zibo Zhuoyue Refractory Co., Ltd., and communicate the customization requirements with them. The supplier will produce according to the technical specifications and drawings provided, and provide samples for the customer's confirmation.

Through the above steps, you can customize the sleeve brick to meet specific needs, and ensure its performance and service life in practical application.
