Production process and advantages of magnesia alumina spinel refractory bricks

Magnesia-alumina spinel refractory bricks are important materials in current high-temperature industrial applications. Due to their excellent high-temperature resistance, erosion resistance and thermal shock stability, they are widely used in high-temperature equipment such as cement kilns, glass kilns and steel smelting. The production process is complex and delicate, and each step needs to be strictly controlled to ensure the quality and performance of the finished product. This article will introduce the production process of magnesia-alumina spinel refractory bricks in detail, and focus on the advantages of magnesia-alumina spinel bricks produced by Rongsheng Refractory Materials Co., Ltd.

Production process

Select raw materials

The main raw materials of magnesia-alumina spinel refractory bricks are high-purity magnesium oxide and aluminum oxide. These raw materials must be strictly screened and proportioned to ensure that the bricks have good refractory properties.

Mixing Ingredients

The selected raw materials are mixed evenly in a certain proportion, and some binders and anti-cracking additives are usually added to enhance the structural strength and heat resistance of the bricks.

Molding and pressing

The mixed raw materials are placed in a mold and pressed into shape. The molded bricks must have a certain shape and size to meet the subsequent sintering and application requirements.

Sintering treatment

After forming, the magnesia-alumina spinel bricks are sintered at high temperature to give them excellent refractory properties in high temperature environments. The sintering process requires strict control of temperature and time to ensure that the structure and performance of the bricks are optimized.

Quality inspection and packaging

After sintering, the magnesia-alumina spinel bricks are strictly inspected for quality to detect whether their appearance and performance meet the requirements. Qualified products will be packaged and molded for use in high-temperature industrial equipment.
