Monolithic refractories are unfired refractories. Foreign countries have developed rapidly since the 1960s, while China only started in the 1980s. And it is mainly used in atmosphere furnaces, and it is rarely used in melting furnaces. The company will improve the performance and quality of monolithic refractories through research on its related information, making it more widely used. The following are related content of monolithic refractories.
The following is a list of contents:
·How Monolithic refractories are made
·Applications of Monolithic refractories
·Advantages of Monolithic refractories
·Development of Monolithic refractories
Methods of making monolithic refractories. There are ramming molding, vibration molding, and spray molding. When the masonry or the overall structure of the refractory brick is partially damaged, it can be replaced by this material or repaired in cold and hot states by spraying and projection equipment, which is fast and economical. It can also be used as the lining of various parts of the kiln and the protective layer and joint material of the masonry according to its material characteristics.
At present, monolithic refractories are used in many fields of furnaces, thermal equipment, and structures, and have achieved significant economic benefits. In the metallurgical industry, iron-making and steel-making systems, steel rolling systems, petrochemicals, electric power, and other industries have achieved good results. As we all know, metallurgical industry kilns are most used in various industrial sectors, the use conditions are very harsh, and the consumption of monolithic refractories accounts for more than half of their total output.
The advantages of monolithic refractories are the simple production process, system energy saving, excellent product performance, arbitrary shape, and long service life. At the same time, the application field has also expanded from low and medium-temperature atmosphere furnaces to high-temperature melting furnaces, so that the application scope of monolithic refractories is different from the past, the scope is more and more extensive, and it has better economic benefits.
Monolithic refractories are a new type of refractory material that does not require pre-firing and is delivered as a loose mixture and baked in form. This material can be made into seamless linings and structures, so it is called integral refractory concrete. The output of monolithic refractories is increasing year by year, especially after the use of composite binders, ultra-fine, and high-efficiency additives, the theoretical guidance of sintering and self-expansion is combined by itself, which innovates varieties and meets the needs of new smelting technologies. From the development trend in recent years, it is not difficult to see that the development characteristics of amorphous refractories are: a variety of varieties, high purity of materials, and rationalization of particle composition. Monolithic refractories have developed to this day, the variety has changed rapidly, and the castables of good quality and easy automation have increased significantly. From the production of monolithic refractories in the world in recent years, it can be seen that the mechanization and automation of innovative gunning and repairing methods and construction methods will be the focus of the development of monolithic refractories in the future.
In recent years, monolithic refractories at home and abroad have undergone rapid changes, and have achieved huge economic benefits in various application fields. The company will continue to improve quality, update varieties and reduce energy consumption in the future popularization and promotion, and strive to develop monolithic refractories to a new stage to make greater contributions in related fields.
