According to the usage characteristics of Refractory Mortar and the materials of its raw materials, there are many types of Refractory Mortars. Different types of Refractory Mortar have different functions.
Types of Refractory Mortar
Clay refractory Mortar is combined with soft clay or chemical binders. Mainly used for joints and repairs of clay bricks. Clay refractory Mortar can be combined with water or phosphoric acid.
High-aluminum refractory Mortar is made of high-aluminum clinker powder, soft clay powder, or chemical binders. For joints in high alumina brick masonry. High-aluminum refractory Mortar is also divided into different grades of mud with different aluminum contents, which are used according to the different aluminum contents of high-alumina bricks.
Corundum refractory Mortar is made of corundum powder and soft clay or chemical binding agent. It is mainly a refractory mortar used to connect the joints of corundum bricks. The aluminum content of this mud is above 80%.
Silicon carbide refractory slurry is mainly silicon carbide powder and is used to combine SiC bricks, corundum SiC bricks, and other masonry slurries. It can also be used as a grouting material and spray paint.
Carbon mud is used for the construction of furnace bottom carbon bricks and ring carbon bricks. It can also be used for smearing and filling between ceramic cups and ring-shaped carbon bricks. Carbonaceous mud has the characteristics of high strength after curing at room temperature.
Carbon refractory slurry is made of anthracite, graphite, and silicon carbide fine powder as raw materials, using resin and additives as cementing materials, and adding a variety of additives. Carbon clay and fine joint paste are both carbon refractory Mortars and are used for thin joint masonry. For example, microporous silicon carbide roasted carbon blocks, microporous molded small carbon blocks, semi-graphite roasted carbon blocks, and microporous carbon blocks.
A slurry without water pressure is a paste or slurry-like material constructed by the extrusion method. It is composed of refractory powder, binder, and admixture. When used, water resin is added and used for press-in repair of the blast furnace body. Generally, two presses are used for construction.
Insulating refractory Mortar is formulated with lightweight refractory powder and binder. It has a small volume density and low thermal conductivity and is used for joint connection of lightweight refractory bricks. Insulation mud is divided into high aluminum and clay. Clay lightweight insulating mud can also be used directly.
Refractory buffer mud is a special refractory Mortar made of refractory raw materials that buffers the thermal expansion stress of refractory masonry. Used in blast furnaces, hot blast furnaces, etc. that need to buffer thermal expansion stress. There are high aluminum refractory buffer mud, siliceous refractory buffer mud, non-aqueous silicon carbide refractory buffer mud, etc.
In short, Refractory Mortar is different types of mud made according to the different needs of different materials. Different materials have different functions, and different binding agents have different effects.
