/ Refractory castables are used to create several
monolithic linings of all types of kilns and
furnaces. But one area where it shines the most
is the creation of castable refractory cement.
They are made with refractory aggregate, powder,
clay, and a certain amount of binding agent and
admixture. A major benefit of castable
refractory cement is that due to the process,
they have high liquidity, are resistant to acid
(a reason why they are referred to as acid proof
cement), and hence can be directly used in
furnaces and kilns as refractory lining.
Types of Castable Refractory Cement There are two
types of castable refractory cement available for
usage low cement castable and ultra-low cement
castable. And it is quite indicative from their
name how they distinguish from each other. Low
cement castable has a lime limit of 1 percent to
2.5 percent, whereas, in the case of ultra-low
cement castable, the time limit is between 0.2
percent and 1 percent. Due to the reduced amount
of cement in them, the fire resistant properties
of this castable refractory cement go through the
roof, making them excellent as refractory cement
for boiler or other high-temperature work. But
that is not the only benefit. There is a
significant improvement in the thermal shock
resistance, slag resistance, and corrosion
resistance of the castable refractory cement,
which are significantly higher than fire
refractory brick.

• Advantages and Application of Castable Refractory
  Cement
• Castable refractory cement is widely used
  primarily as refractory lining in furnaces,
  heating, heat treatment, shaft kilns, blast
  furnace tapholes, and more. But that is not all
  their application is limited to.
• Due to them being high-tech refractory solutions
  developed on common castables, they have low
  porosity characteristics, small pore size, good
  volume stability, superior strength, and high
  density. In addition, they can easily handle
  temperatures up to 800 to 1200 degrees Celsius,
  which is not the case with regular castables.
  That allows them to be far superior castable
  refractory for boiler.
• Different Castable Refractory Cement Has
  Different Applications.
• Clay and high alumina castable refractory cement
  for boilers are typically used in heating
  furnaces and soaking furnaces.
• Low cement castable refractory cement, because of
  its high-temperature resistance, is used in
  burned linings, water cooling pipe wrapping
  linings in a heating furnace, and more
  applications of similar nature. Low cement and
  ultra-low cement castables are particularly used
  when the temperature required to work is quite
  high.
• Chromium containing corundum low cement castable
  is used to line the refining device outside the
  molten steel furnace (only certain parts).
• Chromium containing corundum low cement castable
  is also used to inline the power frequency
  induction furnace. They are high-temperature,
  wear-resistant castable serving multiple
  purposes.
• Low cement castables are used in blast furnaces
  tapping troughs and integral spray guns for hot
  metal pretreatment.
• Because of their high strength, alkali, and
  abrasion resistance, one can find that low cement
  castables have already replaced several products
  that were used in place for them and are now
  widely used across the world. But before you
  purchase castable refractory cement, you need to
  be sure that your supplier provides you with the
  right castable refractory cement. As mentioned
  above, different castable refractory cement
  serves different purposes. In addition, castable
  cement has become an integral part of various
  industries in various applications. So, the best
  thing is to research the castable refractory
  cement and their supplier before placing an
  order for one.
