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.

There are many types of insulating fire bricks. When choosing insulating fire bricks in industrial kilns, it is necessary to choose the appropriate ones according to the actual use temperature inside the kiln, the use conditions of insulating fire bricks, the use cycle and other aspects. This article will introduce the main applications of insulating fire bricks.

Insulating fire brick is a kind of insulating products with a regular shape. It belongs to light insulation refractory material. The common characteristics of this kind of material are small volume density, light bulk density, low thermal conductivity. But the intensity is low, high temperature reburning shrinkage is larger, heat insulation, good moisturizing effect. Refractory brick, also known as firebrick, is made of heat-resistant ceramic materials, similar in shape to ordinary building bricks, so they are often used in building kilns and a variety of thermal equipment. Firebrick won't have chemical change below high temperature on one hand, also be the material with poorer heat conduction commonly. Let's talk about the difference between insulating fire brick and refractory brick.

​The raw materials used for lightweight insulating fire brick can be classified into clay, silica, aluminum and mullite. Light insulating fire brick's insulation is due to the brick body inside contains a large number of air holes (including closed air holes and open air holes). The method that causes stomata has to add combustible matter law, foam law, chemical law. Insulating fire brick has low compressive strength, poor slag resistance, poor thermal vibration resistance, and can not be in direct contact with liquid glass or flame. The article Introduces a few kinds of common insulating fire brick below.
