Monolithic Refractory Materials
Monolithic Refractory materials, also called Bulk refractory (which means unshaped refractory). This kind of refractory material is directly composed of granulated and powdered materials and binders and is directly supplied for use without forming and firing. Generally, granular materials constituting such materials are called aggregates, powdered materials are called admixtures, and binding agents are called cementing agents. This kind of refractory material has no fixed shape and can be made into paste and loose shape, so that it is also commonly called bulk refractory. This kind of refractory material can form a whole structure without seams, so it is also called monolithic refractory material.
Composition of Monolithic Refractory
In Rongsheng Refractory Materials Manufacturer, the basic composition of monolithic refractory material is granular and powdery refractories. According to its use requirements, it can be made of various materials. In order to integrate these refractory materials as a whole, with the exception of a few special cases, generally suitable types and quantities of binding agents are added. In order to improve its plasticity or reduce water consumption, a small amount of appropriately plasticized water reducing agent can be added. In order to meet other special requirements, a small amount of other appropriate additional additives can be added separately.
The monolithic refractory meaning, usually only through the preparation of granular and powdery materials and the kneading process of the mixture can be obtained. The process is simple, the production cycle is short, the thermal energy consumption is low, the integrity is good, the adaptability is strong, and the comprehensive use effect is good.
Classification of Monolithic Refractories
The particles and fine powder of the Monolithic Refractory Products can be composed of refractory of any material.
According to the material of the raw materials, the Monolithic Refractory Materials can be divided into: silicon refractory materials, clay refractory materials, high alumina refractory materials, magnesium refractory materials, dolomite refractory materials, chrome refractory materials, etc.
There are many types of binders for monolithic refractory materials, such as various cements, inorganic salts (water glass, sulfates, phosphates, etc.) and organic substances (tar pitch, phenolic resin, etc.). So that the unshaped refractory materials can also be classified and named according to the binders .
According to process characteristics, unshaped refractory materials can be divided into castables, plastics, ramming materials, spray materials, projectile materials, refractory mud, refractory coatings, etc.
Monolithic Refractory Installation and Application
The Monolithic Refractory installation of the unshaped refractories include ramming, vibration and injection molding. When the masonry or overall structure of the refractory brick is partially damaged, it can be replaced with this material or repaired in cold and hot state by using spraying and projection equipment, which is fast and economical. The monolithic refractory linings can also be seen in various parts of the kiln, according to its material characteristics. So is the protective layer and seams’ material of masonry.
Advantages of Monolithic Refractory Materials
Usually, the monolithic refractories are used for the lining of thermal equipment. It can be baked directly without firing. Compared with refractory bricks, it has the characteristics of simple process (because the firing process is omitted), energy saving, low cost, and easy mechanized construction. It is better than refractory bricks in some thermal furnaces.
