Al2O3 Ceramic Wear Liner

Since its founding, Shandong Qishuai Wear Resistant Equipment Co., Ltd. has always focused on the research & development, production and sale of wear resistant equipment and material. We are a professional group devoting to offer excellent performance wear resistant products for industrial customers from all over the world. By means of advanced production technique and strict quality control, our Al2O3 Ceramic Wear Liner are popular and widely sold both domestically and abroad.

To demonstrate its wear resistance advantages more clearly, below is a comparative test between Shandong Qishuai Wear-Resistant Equipment Co., Ltd.'s Al₂O₃ ceramic wear-resistant lining and standard lining:

Our Advantages:

Acid and Alkali Resistance: In addition to mechanical wear, equipment used in rigorous industrial environments must also resist chemical corrosion. This is particularly true for the many reactors and other storage tanks used in the chemical industry, which are frequently exposed to acid and alkali solutions for extended periods. The chemical resistance of Al2O3 Ceramic Wear Liner is quite strong, and it can resist the erosion of acids, alkalis, and other different chemical substances. The main reason lies in the fact that the chemical structure of Al₂O₃ ceramic is relatively stable, and there is a layer of dense oxide film on the Al₂O₃ ceramic surface. The chemical substance will not contact with the substrate directly, so it protects the substrate from being corroded.

Superior High-Temperature Resistance: In the high-temperature environment of the industrial field, the thermal performance of materials is very demanding. Al2O3 Ceramic Wear Liner still have good physical properties at high temperatures. The ceramic working temperature is stably running below 1600°C at the melting point of 2054°C. The physical phenomenon of softening and deformation does not occur at high temperature due to the special crystal structure and chemical bond energy of ceramics. Therefore, they can greatly improve the service life of blast furnace and reduce the loss of production.

Convenient Installation and Maintenance: We fully recognise that the efficiency of equipment installation and maintenance directly impacts industrial production outcomes. Our Al₂O₃ ceramic wear-resistant liners offer straightforward installation methods and low maintenance costs. Contact our team for installation guidance – clear and easy to follow, significantly enhancing operational efficiency.

We offer Al₂O₃ ceramic wear-resistant liners in a variety of specifications and dimensions to meet the diverse requirements of our customers.

Frequently Asked Questions:

How much better is the wear resistance of Al2O3 Ceramic Wear Liner compared to ordinary liners?

Al2O3 Ceramic Wear Liner have a Mohs hardness of 9 and are almost as hard as diamonds; their wear resistance is much better than that of ordinary liners. According to field testing and case studies, when ordinary liners have the same working conditions as Al₂O₃ ceramic wear-resistant liners, their wear rate may be as high as 5% when they are worn out, while the wear rate of Al₂O₃ ceramic wear-resistant liners is only about 5% of that of ordinary liners. The wear resistance of Al₂O₃ ceramic wear-resistant liners is several times that of ordinary liners, and the multiple depends on the operating environment and conditions.

What is the maximum temperature this lining can withstand? Does its performance deteriorate at high temperatures?

Al₂O₃ ceramic wear-resistant liners have a high melting point of 2054°C and can operate stably for a long time at a temperature below 1600°C. When Al₂O₃ ceramic wear-resistant liners have the same operating conditions, as long as they are not close to or exceed the maximum tolerable temperature, there is no effect on their performance. However, when approaching or exceeding the maximum tolerable temperature, there will be certain effects on the structure and properties of Al₂O₃ ceramic wear-resistant liners. For example, the hardness will decrease slightly. Compared with other commonly used materials, the high-temperature resistance of Al₂O₃ ceramic wear-resistant liners is still very outstanding.

Is installing Al2O3 Ceramic Wear Liner complicated? Are special tools required?

It is not complicated to install Al₂O₃ ceramic wear-resistant liners. You may refer to the simple instructions we provide. Generally, you need to prepare common tools such as cutting machine, angle grinder, rubber mallet and gloves, and special adhesive or mounting accessories. If the shape is special or the equipment is large, you may need to prepare some auxiliary tools, but our technical personnel will provide detailed guidance.
