With the continuous development of science and technology, materials have also been continuously innovated, and materials such as cast stone, cast steel, alloy, ceramics have appeared one after another. Among them, silicon carbide ceramics have become the most extensive wear-resistant materials due to their high wear resistance, oxidation resistance, and corrosion resistance, occupying the entire ceramic market share. The following editor will introduce the performance characteristics and production process of silicon carbide ceramics in detail for you. Let's learn with the editor! Performance characteristics of silicon carbide ceramics 1. Excellent wear resistance, continuous use for more than 10 years According to the research, the wear resistance of silicon carbide ceramics is 266 times that of manganese steel, and 171.5 times that of high-chromium cast iron. The wear resistance is excellent. The application of wear-resistant ceramic composite elbows in the pulverizing system greatly reduces the wear of the equipment, and the durability is at least 10 years, reducing the frequency and cost of maintenance. 2. The lining ceramic has high strength, high hardness and light weight For example, the Rockwell hardness of corundum ceramic is HRA90-98, which is much higher than that of wear-resistant steel and stainless steel. The density is only half of steel, and the weight of ceramic elbow is only 1/3 of wear-resistant steel elbow, which is easy to install and replace. 3. The inner wall is smooth and does not block powder Silicon carbide ceramics are densely sintered at high temperature, and the surface is smooth after grinding and deburring treatment. The inner wall of the ceramic composite elbow is flat and smooth without blocking powder. 4. Low resistance The surface of the wear-resistant ceramic tube is smooth. And without rust and dirt, its internal surface smoothness is better than any metal pipe. Therefore, small running resistance can reduce running costs. 5. Low cost The ceramic tube is light in weight, has good welding performance, and is convenient for construction and installation. Therefore, comprehensive installation and operation will reduce many costs. In addition, the performance of silicon carbide ceramics compared with other wear-resistant pipes can not only be favored by the market and continue to replace some traditional anti-wear materials, but also with traditional anti-wear materials such as cast stone, cast steel and centrifugal casting Compared with ceramic materials, it has many advantages. Silicon carbide ceramic production process The production and processing of silicon carbide ceramics is not a simple matter, it has to consider many factors, and it needs to be very careful when processing, so as to ensure that the performance of silicon carbide ceramics is fully exerted to the extreme state. About the specific production process of silicon carbide ceramics, the following small series will introduce you as follows: Synthesis of silicon carbide ceramic powder: Because natural silicon carbide ceramic powder does not exist on the earth, most of the silicon carbide ceramic powders we currently use are artificially synthesized. Acheson's method or chemical method and thermal decomposition method are generally adopted. Acheson uses electricity to achieve high temperature reaction to achieve the purpose of synthesis; chemical method is to allow high-purity silicon and carbon black to react directly. The purpose of synthesis; and the method of thermal decomposition is to allow polycarbosilicate to decompose in the temperature range of 1200 to 1500 has achieved the purpose of synthesis. Sintering of silicon carbide ceramics: After the powder synthesis of silicon carbide ceramics, the sintering work of silicon carbide ceramics is pressed. There are pressureless sintering methods and hot press sintering methods used in the industry, but hot press sintering is the most commonly used method. Method, it is through the addition of certain metal additives, and then through hot pressing sintering technology to achieve the densification of silicon carbide ceramic powder, and then add some additives, usually B or B compound, so that the silicon carbide crystal The grains become small. Sometimes we must pay attention to the composition and dosage of sintering additives, which will affect the sintering work and the effect of sintering to a great extent. Cooling and setting: After the sintering work of the silicon carbide ceramic is completed, it is the cooling work. While cooling, the silicon carbide ceramic can be subjected to a certain setting work, of course, the premise is that the silicon carbide ceramic produced is to be shaped, if only To produce its prototype, this step is not necessary. In the production process of silicon carbide ceramics, the staff should strictly check each link, so that only high-quality silicon carbide ceramics can be produced.
