Ultra Low Cement Castable Definition
 
Ultra low cement refractory castables are developed on the basis of low cement refractory castables. The amount of aluminate cement is generally 2.5% to 5%, the performance is superior to the low cement refractory castable.
 
The coagulation hardening mechanism of ultra-low cement refractory castables is that the agglomeration combines to play a leading role as a cement coagulant. For example, when SiO2 ultrafine powder is added, colloidal particles are formed after water, and Al3+ and Ca2+ ions which are slowly dissolved during hydration of calcium aluminate are adsorbed to lower the potential, coagulation hardening occurs when the "isoelectric point" is reached. In addition, the surface of the active SiO2 can form a silanol group, dehydration bridges during the drying process to form a siloxane network structure, while adsorbing Al3+, Ca2+ and Na+ ions brought in by the electrolyte can also produce coagulation hardening.

Ultra Low Cement Castable Specification
 

 
Ultra Low Cement Castable Application
 
1. Ultra low cement castable is used in glass kiln, colored flash furnace, sintering machine, ladle and other linings are constructed and produced.
 
2. Castable ultra low cement refractory is used in the whole construction and preparation of the soaking furnace and the heating furnace wall top. Burning nozzle, slag ball blocking slag, tapping groove to make intermediate package permanent lining.
 
3. Refractory ultra low cement castable application in RH vacuum degassing device, SLKIP metallurgy integral spray gun, CHS and ladle gas supply brick (breathable brick) and the use of corundum brick for petrochemical and coal gasification equipment.
 
4. Ultra low cement refractory castables application in industrial kiln such as metallurgy, petrochemical, machinery manufacturing, electric power and building materials, such refractory castables have been commonly used to replace traditional fired refractory products as a lining. The vibrating low cement refractory castable is mainly used as the backing lining, such as lining for heating furnace, various heat treatment furnaces, electric furnace cover, shaft kiln, rotary kiln, blast furnace tap hook, ladle.
 
Ultra Low Cement Castable Condensation Hardening Mechanism
 
1.The coagulation hardening mechanism of refractory ultra low cement castables is that the agglomeration combines to play a leading role as a cement coagulant. For example, when SiO2 ultrafine powder is added, colloidal particles are formed after water,  Al3+ and Ca2+ ions which are slowly dissolved during hydration of calcium aluminate are adsorbed to lower the potential. Coagulation hardening occurs when the "isoelectric point" is reached. In addition, the surface of the active SiO2 can form a silanol group, which dehydrates and bridges to form a siloxane network structure during the drying process, and simultaneously adsorbs Al3+, Ca2+ and Na+ ions brought in by the electrolyte, and can also produce coagulation hardening.
 
2.The quality of ultra-low cement refractory castables is inseparable from the setting time, volume stability and fineness of cement particles.
 
3.The setting time is directly related to the hardening and strength of the castable ultra low cement refractory. Generally, there is sufficient time for the construction to complete the mixing, transportation, molding and other processes. The setting time of the low cement refractory castable should not be too short. Refractory castable is hoped that the cement can harden as soon as possible and produce hardness. Then the cement setting time should not be too long, and the setting time is generally 45 minutes - 390 minutes.
 
4.Volume stability is closely related to the quality of low cement castables. If the volume change is not uniform, that is, the volume stability is poor, warping and cracking will occur easily, which will reduce the quality and even cause accidents. The fineness determines the eligibility of low cement castables. The finer the cement particles, the larger the specific surface area, the faster the hydration reaction will be, the higher the early and late strength. A specific surface area greater than 0 square meters per kilogram is acceptable.
 
5.The low cement refractory castable has a low calcium oxide content, so that the resulting eutectic phase can be reduced, thereby improving refractoriness, high temperature strength and slag resistance. When the low cement castable is heated and baked, there is no problem that a large amount of hydration bond is broken and the medium temperature strength is lowered. As the heat treatment temperature is increased, the strength is also increased. Ultra Low cement castables also have very low water requirements, low porosity and high bulk density.
