monolithic refractories

Introduction Monolithic refractory products are vital in various industrial processes due to their unique properties and adaptability. These unshaped refractories can be engineered into any desired form, offering significant advantages over traditional refractory materials.

The manufacture of monolithic refractories has the method of ramming molding, vibration molding and jet molding. When the masonry of the firebrick or the whole structure is partially damaged, the material can be replaced or the cold and hot repair can be carried out by spraying and projection equipment, which is both rapid and economical. It can also be used as the lining of each part of the kiln and the protective layer and joint material of masonry according to its material characteristics. The production process of refractory castables and refractory plastics is described below.

​Monolithic refractories as a very important part of refractories, when the finalization of refractories can not meet the construction requirements, it is necessary to be monolithic refractories as the main construction materials. The construction of monolithic refractories is simple and efficient. They are mostly used for casting, kiln wall spraying, repairing, grouting, etc. According to the construction method and material properties, monolithic refractories can be divided into pouring material, plastic, ramming material, spraying material, dry mixing material, projection material and coating material.

Although the use of monolithic refractories has been for many years, it has not been generally accepted in the industry until the 1960s. Refractory aggregate, fine powder and binder (or additive) according to the use of the formula by the appropriate proportion of the mixture to form a monolithic refractory, can be used directly or can be added to the appropriate amount of liquid for use. In terms of transportation, monolithic refractories usually in the form of bulk materials, and then according to the use of the site requirements of different construction methods.

Monolithic refractory material is a new type of refractory material, also known as non-burning refractory material or scattered refractory material, which can be directly used after delivery and molding and baking, without being fired in advance and loose mixture. With the material can be made into no joint lining and structures, so the monolithic refractory material. Monolithic refractories generally use cement as a binder. Here is a simple introduction to the history of monolithic refractories. According to the characteristics and application of monolithic refractories, it can be divided into three stages of development.

Monolithic refractories by a certain size grading refractory aggregate and powder, binder, admixtures and become refractory materials, also known as scattered refractory materials. Monolithic refractories are used for the lining of thermal equipment. They can be baked directly without firing. Compared with firebrick, monolithic refractories have a simple process (because of eliminating the burning process), energy saving, low cost, easy to mechanized construction and other characteristics, in some thermal equipment to use the effect is better than firebrick.

Monolithic refractory, also popularly known as unshaped refractory, has a variety of sizes and shapes, making it a special type of refractory material. Monolithic castable refractory has a wide range of minerals in its content, which is quite different from other refractory material’s compositions. Thus, monolithic refractories have some prominent properties, such as low permeability, improved stability, better insulation and so on. These advantages are partly resulted from the manufacturing process of monolithic castable refractories. In this passage, detailed information about how to manufacture monolithic refractory cement will be provided.
