Fire brick mortar is an important bonding material in the process of refractory brick masonry. If the quality of refractory mortar is not up to standard, it will seriously affect the service life of refractory bricks. Contact Kerui to get high-performance heat resistant brick mortar.
The use scenarios of fire brick mortar will change according to the different materials. We mainly use magnesia refractory mortar for masonry magnesia bricks in converters, electric furnaces and non-ferrous metal smelting furnaces. We mainly use silica mortar for masonry magnesia bricks in coke ovens and glass kilns. Also, we widely use refractory clay brick mortar and it plays a great role in construction, industry, metallurgy and other industries. Read on to learn about the main characteristics of Kerui refractory mortar.
What type of mortar is used for fire brick? The working conditions of the refractory mud in the joints of refractory masonry bricks should be exactly the same as those of refractory bricks. Therefore, the main technical indicators of the two, refractoriness and chemical composition, should also be the same or compatible. For example, high alumina mortar should be used for masonry of high alumina bricks and magnesia mortar should be used for magnesia refractory bricks.
In addition, you should select the type and grade of fire brick and mortar according to the working conditions of the furnace. If you are not sure about the type of mortar for firebrick masonry you need, you can contact us for a free technical consultation.
The steps to use good refractory mortar for refractory bricks are as follows:
First, clean the damaged area and make sure it is clean and dry. Next, use a spatula to apply the well-mixed mortar to the damaged area, making sure it is evenly filled and compacted. Finally, let the repaired area dry and cure naturally. You need to avoid applying mechanical stress or high temperatures to it during the drying period. After we complete the repair, gradually increase the temperature to acclimate it to the hot environment.
There is a big difference between refractory mortar and refractory cement. Refractory mortar is used for laying refractory bricks (mixed with water or other liquids). We can use it directly as a finished product. However, we use high temperature refractory cement as a binder material for various refractory aggregates. The refractory castable made from it is also used as a material for kiln lining.
