Introduction
Today, sintering technology has become the mainstream production process of steel production and even the production of many materials. With the rapid development of modern industry, the world has to make great efforts to reduce energy consumption, reduce emissions and reduce production costs. As an important production process of a variety of materials and products, sintering technology goes from traditional sintering to advanced sintering technology, so as to continuously improve product quality and reduce production cost. It can be said that sintering technology has become the cornerstone of world industrys sustainable development.
Sintering Technology
Sintering technology is a kind of material synthesis process in which the heating process of unshaped powder material is accelerated and the porous structure of the material is obtained. After a series of complicated physicochemical processes, the materials are sintered together uniformly. In order to reduce the discontinuity of the material, the grain is also made smaller. For many materials, such as powders containing ferric oxide, limestone and clay, they must go through sintering process before being used in other production.
Advantages of Sintering Technology
First of all, sintering technology can reduce the cost of materials, because the powder material can be released after finishing the sintering process instead of using pellets, so it can improve the utilization of materials and reduce the cost of materials. Secondly, sintering technology can form a compact structure of materials. When the compression of the sintered material particles is formed during the sintering process, a homogeneous and compact structure can be formed, so that the strength of the material increases significantly.
Disadvantages of Sintering Technology
The surface porosity and shrinkage of sintering materials are also important indexes for measuring the quality of sintering. Generally speaking, the surface porosity of sintered materials is low and the shrinkage is large, which is a stubborn problem of sintering technology. In addition, another biggest disadvantage of sintering technology is energy consumption. Due to the large amount of heat needed in the sintering process, it has a high requirement for energy.
Application of Sintering Technology
The application of sintering technology has been applied in many fields. For example, sintering is the essential process in steel making. Sintering technology is also widely used in powder metallurgy production. In this production process, the metal powder is made into a certain shape, size and performance through the sintering of metal powder. In refractory production, refractories can be made by sintering refractory powder. In addition, sintering technology is also used in ceramics production and so on.
Advanced Sintering Technology
With the progress of social science and technology, advanced sintering technology has developed rapidly. In terms of sintering temperature, sintering can use high temperature, medium temperature and low temperature process, and these processes can be realized by different sintering methods. In terms of sintering structure, different particle sizes and shapes can be realized by different sintering methods. In addition, the increase of sintering speed can also significantly improve the sintering efficiency and reduce the energy consumption of sintering.
Conclusion
In summary, sintering is an important process for metal and non-metal production, and sintering technology has gone from traditional sintering to advanced sintering technology. The advanced sintering technology not only can improve sintering efficiency, but also reduce the energy consumption of sintering. As a production process of many materials, sintering technology has become a part of the sustainable development of world industry.
