The castable refractory mortar consists of refractory powder, binder and additive. Almost all refractory materials can be made into powders used to make refractory mortar. The particle size of the refractory mortar will vary according to the requirements of use. The ultimate particle size is generally less than 1 mm, and some are less than 0.5 mm or less.
Forming Method of Castable Refractory Mortar
Almost all refractory materials can be made into powders used to make castable refractory mortars.
The ordinary refractory mortar made of refractory clinker powder and appropriate amount of plastic clay as a binder and a plasticizer has a low room temperature strength and a high strength under the formation of a ceramic bond at a high temperature.
A chemically bonded refractory mortar using a hydraulic, gas-hard or thermosetting bonding material as a binder, hardens before a certain chemical reaction occurs before the ceramic bonding temperature is formed.
Refractory Mortar Characteristics and Applications
- Good plasticity and convenient construction;
- Strong bonding strength and strong corrosion resistance;
- High refractoriness, up to 1650 ° C ± 50 ° C;
- Good resistance to slag invasion;
- Good thermal exfoliation.
- Bulk density: 1.8-2.2g/cm3.
The castable refractory mortar is mainly used in coke ovens, glass kiln furnaces, blast furnace hot blast stoves, and other industrial kiln furnaces. The applied industries are: metallurgy, building materials, machinery, petrochemical, glass, boiler, electricity, steel, cement, etc.
Refractory Mortar Selection
According to the material, refractory mortar can be divided into clay, high-aluminum, siliceous and magnesia refractory mortar. When selecting the material of the refractory mortar, it should be considered to be consistent with the material of the refractory product of the masonry. In addition to the crevice material, the castable refractory mortar can also be used as a protective coating for the lining by smearing or spraying.
