How to reduce the production cost of alumina wear-resistant ceramics?

图片
The production cost of alumina wear-resistant ceramics is high. In order to reduce the production cost, the following aspects can be considered: I. Raw material selection 1. Select cost-effective raw materials: Under the premise of ensuring product quality, select alumina powder with relatively low price but satisfactory performance, such as industrial alumina or calcined alumina instead of high-purity alumina powder. At the same time, we can explore the use of a mixture of alumina and other ceramic materials to reduce costs through reasonable proportions. 2. Joint procurement of raw materials: Cooperate with multiple companies for joint procurement and use economies of scale to reduce procurement costs. II. Process optimization 1. Optimize the preparation process: Improve production efficiency, reduce energy consumption and waste generation by improving the preparation process. For example, use advanced sintering technology and mold design to shorten sintering time and reduce energy ...

The Characteristics and Applications of Alumina Ceramic Liner with hole

图片
Alumina ceramic liner with hole , mainly composed of high-purity α-alumina (Al₂O₃) through high-temperature sintering, typically has an alumina content higher than 92%. This type of liner has a flat plate structure, with a through-hole on the surface. The hole diameter and spacing can be designed according to application requirements. Its performance characteristics include high hardness, excellent wear resistance, good chemical corrosion resistance, and outstanding high-temperature resistance, with a working temperature of up to 1600 degrees Celsius. Moreover, its structural design takes into account both lightweight and mechanical strength, making it convenient for installation and maintenance. In the industrial field, alumina ceramic liner with hole is widely used in material conveying systems, equipment protection, and ventilation and dust removal devices. For instance, in industries such as thermal power generation, cement production, and steel smelting, they are employed as inter...

Ceramic Saddle Ring: Characteristics, Applications, and Usage Guidelines

图片
Ceramic saddle rings are ceramic random packing materials primarily composed of silicon dioxide (SiO₂) and aluminum oxide (Al₂O₃), manufactured through high-temperature sintering. They exhibit properties such as resistance to strong acids, high-temperature tolerance, and high compressive strength (acid resistance ≥99.9%, alkali resistance ≥88%, compressive strength ≥10 N/mm²). Designed as an improvement over traditional saddle rings, they feature serrated or corrugated protrusions on smooth curved sides and added perforations on the saddle back, optimizing fluid pathways to significantly enhance mass transfer efficiency and reduce pressure drop. The surface of ceramic saddle rings incorporates a serrated/corrugated design and integrated curved channels, which increase gas-liquid contact area, reduce flow dead zones, and improve mass transfer efficiency by guiding gas along curved paths and minimizing liquid wall flow. Internal perforations further promote multidirectional gas and liqui...
