Carbon materials production kilns refractory materials
In the metallurgy, chemical and other related industries, the use of carbon materials production kiln is an important part of the production process. This kind of kiln is not easy to be corroded by the temperature, and its resistance to temperature depends largely on its refractory materials. Refractory materials are used to point out that materials that are resistant to high temperatures are used in kilns.
There are many types of refractory materials for carbon materials production kilns. The most common ones used in the market come in four forms: fire clay, clay-high alumina, magnesia-chrome and magnesia-spinel. They are used as lining materials to protect the kiln in both corrosion and high temperature.
Fire clay refractory material is a special material used in kilns. The material is made up of refractory clay, fire clay and other minerals. The fire clay refractory material is one of the best known refractory materials, because it is simply cheap and resistant to a wide temperature range, such as 1000°C.
Magnesia-chrome refractory material is also known as basic refractory material. This refractory material has good chemical stability, high temperature resistance and good resistance to shock. The Magnesia-chrome material is particularly used for carbon production kilns, because of its good slag resistance.
The fourth type of refractory material for carbon materials production kilns is magnesia-spinel material. This material is made of magnesia, alumina and chrome oxide, where the alumina and chrome oxide are the main components, and the magnesia content is relatively low. This kind of material has good high temperature resistance and slag corrosion resistance.
These four types of refractory materials are very different, and they have their own advantages and disadvantages. Generally speaking, they all have good high temperature resistance and can resist erosion at high temperatures. When selecting, we should select according to the characteristics of the fuel and the temperature of the kiln.
In addition, the installation of the refractory material is also very important, because the incorrect installation will affect the life of the refractory material, but also affect the normal operation of the kiln, so proper installation is very important.
The proper use of refractory materials in carbon materials production kilns can ensure the normal service life of these kilns. Therefore, it is necessary to choose suitable refractory materials for the particular fuel condition and working temperature of the kiln, and to install the refractories according to the provisions of the manual. In this way, the use of the refractories can be truly maximized, and the service life of the kilns can be truly extended.
