Refractory mud, refractory cement, and refractory castables are three different materials. Refractory mud is the joint material or bonding material when building refractory bricks. Refractory cement is a high temperature resistant cementing material. There are many refractory castables. The composition of the material. First of all, you must understand the characteristics of refractory mud, refractory cement and refractory castables before you can choose them when you use them. Regarding the use of refractory mud, refractory cement or refractory castable with high temperature resistance, the appropriate choice is made according to different situations. Next, let’s share with you the technicians of Henan Lite Refractory Cement!
Refractory mud can also be called refractory mud. When the refractory bricks are used for masonry masonry, refractory mud should be used. When masonry is made, the refractory mud of the same material should be used according to the material of the refractory bricks. High-alumina bricks are built with high-alumina fire mud, magnesia bricks are built with magnesia fire mud, and carbon bricks are built with charcoal fire mud and so on.
High-alumina cement is a cementing agent and needs to be mixed with refractory aggregates or high-alumina aggregates of different particle sizes to have strength. High-alumina cement and refractory castables are related, because refractory castables must have refractory cement as a bonding agent, so that various refractory aggregates can be cemented together to have structural strength and wear resistance. If refractory cement is used alone, the strength is low and it is easy to crack or peel off, especially as the temperature increases, this manifestation becomes more serious. Therefore, high alumina cement cannot be used alone.
Refractory castables should be used in areas where high-temperature kilns are in direct contact with flames and are damaged by corrosive gases. Refractory castables are various refractory aggregates as powder as the main raw material, and refractory cement is combined with anti-shrinking agent, It is composed of anti-explosive fiber, coagulant and other admixture materials. It is poured into an integral lining material without gaps, and has high structural strength and resistance to slag penetration.
In other words, refractory mud is a joint material used in the construction of refractory bricks. Refractory cement is a binder material used for unshaped refractory materials. Refractory castables are used as lining materials for high-temperature kilns. They can be casted, self-flowed, rammed, sprayed, and custom-made castable precast block masonry construction.
There are many kinds of refractory castables. Commonly used are high-alumina castables, corundum castables, low cement castables, mullite castables, wear-resistant castables, impermeable materials, self-flowing castables, plastics, etc., castables It can be used as the lining of ultra-high temperature kilns.
