Classification and composition: Unshaped refractories are composed of refractory aggregates and powders, binders,Unshaped refractory admixtures, etc. The dosage should be determined according to the types and uses of the unshaped refractories. Of course,Unshaped refractory the dosage of various components depends entirely on the variety and Depending on the application,Unshaped refractory the individual is very different. For example,Unshaped refractory the cement used as a binder in the low-cement refractory castable and the water consumption are relatively low, while the water (or liquid) volume of the refractory mortar is greatly increased.
There are many varieties of monolithic refractories,Unshaped refractory and their classification methods are also different. Unshaped refractory materials are mainly classified according to their construction characteristics,Unshaped refractory and can also be classified according to their porosity, the types of binders used, and the materials of refractory aggregates. Classified by porosity: There are two types of dense amorphous refractories and insulating amorphous refractories. Dense monolithic refractories are also called ordinary or heavy monolithic refractories,Unshaped refractory and insulated monolithic refractories are also known as light monolithic refractories.
According to the international standard (ISO1927-75) classification,Unshaped refractory the sample porosity of the insulated unshaped refractory lining after drying should not be lower than 45%. Classified by construction characteristics: mainly include refractory castables, refractory spray coatings,Unshaped refractory refractory gunning materials,Unshaped refractory refractory plastics, refractory ramming materials, refractory pressure injection materials,Unshaped refractory refractory projection materials, refractory coating materials, refractory slurry and dry vibrating materials. Refractory castable. Refractory castables are also called refractory concrete or refractory castables. They are made of refractory aggregates and powders and appropriate binders and additives. They have good thixotropic properties and are generally constructed by pouring or pouring vibrating methods.
Refractory spray paint and gunning material. The composition of refractory spray paint and gunning material is close to refractory castable,Unshaped refractory and the particle size distribution should be adapted to the special requirements of spraying or gunning construction. The construction methods using air motive tools include wet,Unshaped refractory dry and semi-dry methods. There is not much difference between refractory spray paint and gunning material. Gunning material is named after it is used to repair furnace lining. Refractory and plastic. Refractory plastics are made of refractory aggregates and powders with appropriate binders and admixtures. They are in the form of mud or irregular masses. They can maintain good plasticity within a certain period of time. They are generally rammed by wind Tool construction.
Refractory ramming material. The refractory ramming material is made of refractory aggregates and powders, appropriate binders, admixtures, etc.Unshaped refractory in a loose shape,Unshaped refractory and is constructed by a strong ramming method. Refractory pressure injection. Refractory pressure injection is composed of refractory aggregate, powder, binder and admixtures,Unshaped refractory and is in the form of paste or mud. It is constructed by pressing the material in with squeezing torque,Unshaped refractory so it is also called refractory pressure injection.
