The process of customizing high alumina bricks usually includes the following key steps:

I. Identifying needs

Size and shape: determine the size and shape of the required high-alumina brick, including standard size (such as 230×114×65 mm) or special-shaped brick (such as arch brick, side arch brick, end arch brick, key brick, checkers brick, inclined brick, etc.).

Chemical composition: according to the chemical properties of the use environment, choose the appropriate alumina content (such as 48%-85%).

Performance requirements: define the performance indexes of high-alumina brick, such as refractoriness, softening temperature under load, slag resistance and thermal shock stability.

II. Selecting suppliers

Choosing a supplier with customization ability can provide quality control of the whole process from raw material inspection to finished product packaging.

Confirm whether the supplier supports the customization of special-shaped bricks and provide the delivery time and price of customized services.

III. Providing detailed information

Provide detailed customization requirements to suppliers, including size drawings, chemical composition requirements, performance indicators, etc.

Confirm whether sample testing is needed to verify whether the customized brick meets the specific use requirements.

IV. Production technology

Raw material preparation: the supplier will select suitable raw materials such as bauxite and alumina powder according to the customization requirements, and crush, screen and remove impurities.

Batching and molding: raw materials are mixed according to the customized proportion, and the green bricks are made by pressing molding or pouring molding.

Drying and firing: After drying to remove water, the green bricks are fired in a high-temperature kiln, and the firing temperature is usually between 1500℃ and 1600℃.

Quality inspection: the fired high-alumina brick needs to undergo strict quality inspection to ensure that it meets the customization requirements.

V. Packaging and delivery

Custom-made high-alumina bricks are usually packed in wooden pallet to ensure the safety during transportation.

The delivery time is usually 5 to 7 working days, depending on the customization complexity and the supplier's production arrangement.

VI. After-sales service

Some suppliers provide after-sales services, such as product quality assurance, instruction and technical support.

Through the above steps, you can customize high-alumina bricks according to specific needs to meet the application requirements of different industrial scenes.
