Product Description
low cement refractory castable, ultra low cement no cement castable
Castable Refractories, Castables, or refractory concretes are predominantly dry, granular refractory mixes designed to be mixed on site with water and capable of curing to a stable dimensional form through hydraulic or chemical setting.
Castable refractories are particularly suited to the molding of special shapes and parts at the installation site. Castables can be used for forming complete furnace linings and other unique shapes. They can be applied by pouring, pumping, troweling, funning, and shotcreting.
Hongtai Refractory produced Low-cement castables, ultra-low or no cement castables are made by ultrafine powder with the same or similar chemical composition with main material to replace most or even all of cement.Refined, scientific use of optimized particle gradation, powder, particle morphology and other factors, adding trace Of the dispersant (water reducing agent) and the proper amount of retarders and other compound admixture prepared.

Product Uses
Low cement, ultra-low cement castables have a wide range of applications, in addition to the cement industry and petrochemical industry has been widely used. The brief description of some applications are as follows:
(1) ladle
Ladle, especially for the lining of more than 150t large ladle, can save a lot of labor and working hours. US steel mill select low cement castable for 198t converter ladle lining, improved ladle life, with good economic returns.
(2) large tundish
Japan's steel mill 65t slab casting tundish use low cement castable, to improve the lining cracking, peeling and bulging phenomenon, so that the service life of tundish increased to 45 times,three times than the original ordinary castables .
(3) heating furnace
A steel plant using clay-bonded low cement castables for high-speed wire plant heating protection. Heating furnace furnace body is big, the bottom area is 368.5m2. After use the effect is very good.
(4) cement kiln
With the new application of the new suspension preheating chamber (NSP), the refractory materials are put forward higher requirements, especially the alkali resistance of the materials. K. Harrah et al. Studied that low cement castables are much more resistant to alkaline than ordinary castables and are better resistant to alkali after adding SiC.
In short, low cement, ultra low cement castable because of its excellent performance, the use of the scope is growing, in metallurgy, petrochemical, building materials and other industries show a broad application prospects.
