The customization process of refractory clay brick is a complex and elaborate production process, involving many links. From raw material selection to final product delivery, it needs to be adjusted and optimized according to the specific needs of customers. The following are the detailed steps of the customization process of clay refractory bricks:

I. Communication and assessment of needs

Customer consultation: customers put forward customized requirements to refractory manufacturers, including the use environment, temperature range, chemical composition requirements, shape and size, etc.

Technical evaluation: the manufacturer evaluates whether these requirements can be met according to the needs of customers, and provides preliminary technical solutions and quotations.

II. Selection of raw materials and formulation design

Selection of raw materials: according to customers' needs, select suitable main raw materials such as refractory clay, alumina and silica, and necessary additives.

Formula design: according to the chemical composition and performance index required by customers, design a reasonable raw material formula. For example, high alumina clay bricks need higher Al₂O₃ content.

III. Preparation and mixing of raw materials

Preparation of raw materials: crushing, sieving and drying the selected raw materials to ensure that the particle size and moisture of the raw materials meet the requirements.

Mixing and stirring: use automatic batching system and powerful mixer to mix the raw materials evenly according to the designed proportion to ensure the consistency of the mixture.

IV. Molding process

Selection of forming method: according to the shape and size requirements of brick, choose the appropriate forming method, such as press forming, extrusion forming or casting forming.

Molding operation: put the mixed raw materials into the mold and shape by high pressure or extrusion to ensure that the size and shape of the brick meet the design requirements.

V. Drying and firing

Drying: Place the formed brick blank in drying equipment, and slowly raise the temperature to remove moisture to prevent cracks during firing.

Sintering: put the dried brick blank into a high-temperature kiln for sintering. The sintering process is divided into three stages: preheating, sintering and cooling, and temperature control is very important.

VI. Quality inspection

Appearance inspection: check whether the size, shape and surface quality of the brick meet the requirements.

Performance test: chemical composition analysis, fire resistance test, compressive strength test, etc. are carried out on the finished brick to ensure that its performance reaches the standard.

VII. Packaging and delivery

Packaging: According to customer's requirements, the finished brick is packaged, usually with wooden pallet, plastic film and steel belt for multi-layer packaging.

Delivery: transport the packaged refractory bricks to the place designated by the customer to ensure the safe arrival of the products.

VIII. After-sales service

Technical support: provide instructions on the use of refractory bricks and construction suggestions.

Quality tracking: track the use of products and solve possible problems in time.

Through the above steps, the customization process of refractory clay bricks can ensure that the products fully meet the specific needs of customers and meet the use requirements of different industrial scenes.
