Corundum bricks, as a critical type of refractory material, are widely used in high-temperature industrial fields such as metallurgy, ceramics, and petrochemicals due to their excellent high-temperature resistance, wear resistance, and corrosion resistance. The density and strength of corundum bricks are the core indicators determining their service performance and service life. In the traditional forming process of corundum bricks, problems such as uneven density distribution, low compactness, and insufficient strength often exist, which restrict the application effect of corundum bricks. With the development of intelligent manufacturing technology, servo precision presses have gradually become the core equipment in the forming process of corundum bricks, significantly improving the density and strength of products through precise control and advanced process matching.

The key to servo precision presses enhancing the density of corundum bricks lies in their precise control of pressure and displacement. Different from traditional mechanical presses with fixed stroke and pressure, servo precision presses adopt servo motor drive technology, which can realize stepless adjustment of pressure, speed, and stroke according to the characteristics of corundum brick powder and the requirements of the forming process. During the pressing process, the servo precision press can apply gradient pressure to the corundum brick powder: in the initial stage, a lower pressure is used to make the powder evenly distributed in the mold and discharge the air in the powder gap; in the middle stage, the pressure is gradually increased to promote the mutual extrusion and rearrangement of powder particles; in the final stage, a stable holding pressure is maintained to further eliminate internal pores. This staged pressure control mode effectively avoids the phenomenon of uneven density caused by rapid pressure application in traditional presses, making the internal structure of corundum brick blanks more compact.

In terms of improving the strength of corundum bricks, servo precision presses play a positive role in optimizing the grain structure of corundum bricks and enhancing the bonding force between particles. On the one hand, the precise pressure control of the servo precision press can make the corundum powder particles closely fit, reduce the number of internal pores and microcracks, and improve the integrity of the brick blank. On the other hand, the adjustable pressing speed of the servo precision press can match the fluidity of different corundum powder materials. For powder with poor fluidity, a lower pressing speed is adopted to ensure that the powder can fully fill the mold cavity; for powder with good fluidity, an appropriate increase in speed can improve production efficiency on the premise of ensuring forming quality. After sintering, the corundum bricks formed by servo precision presses have a more uniform grain size and stronger intergranular bonding, thus showing higher mechanical strength.

In addition, the high stability and repeatability of servo precision presses also provide a reliable guarantee for the consistent quality of corundum bricks. In mass production, the servo precision press can accurately replicate the optimal forming parameters, avoiding the quality fluctuation caused by human operation errors or equipment performance degradation in traditional presses. At the same time, the servo precision press is usually equipped with an intelligent monitoring system, which can real-time monitor parameters such as pressing force, displacement, and speed during the forming process. Once an abnormal situation occurs, it can immediately issue an alarm and adjust, ensuring that each corundum brick blank meets the preset density and strength requirements.

To sum up, servo precision presses have obvious advantages in improving the density and strength of corundum bricks. Through precise pressure and speed control, optimized forming process, and stable production guarantee, they effectively solve the quality problems existing in the traditional forming process of corundum bricks. With the continuous advancement of industrial upgrading, servo precision presses will play a more important role in the corundum brick production industry, helping to promote the high-quality development of the refractory material industry and provide more reliable material support for high-temperature industrial fields.
