Pouring Material Construction Precautions

The construction of castables depends on the rheological properties of the castables, and the rheology of the castables depends on the particle size of the castables ( the ratio of aggregate to binder). At the same time, according to the cement kiln process requirements (including process temperature, dust content, etc.), to improve the alkali and wear resistance of castables.

Aggregate mainly use alum stone, base material selection of alumina (а-Al2O3) powder, silica powder and pure calcium aluminate cement, alumina powder added. Increase the alumina powder on the high temperature strength and wear resistance of castables will be greatly improved, but the amount of alumina powder is too large, will affect the castable construction performance, but also on the castable alkali and erosion have a negative impact The Therefore, the addition of alumina powder, the castant on the overall performance plays a vital role.

Adding the right amount of pure calcium aluminate cement, can improve the high temperature use of castables and low temperature use strength. But too much added, will affect the castable construction performance, but also shorten the casting time of hardening. Therefore, the castable in the pure calcium aluminate cement must be appropriate. The amount of water added during construction.

The construction performance of the castable is not obtained by simply adding water. Add too much water, aggregate and base material will occur, affecting the use of castable properties, but also reduce the density of castables, strength, alkali and wear resistance. Lack of water, poor construction performance, the material can not flow properly and to achieve dense filling, the bubble row does not come out, can not form a close accumulation, will also affect the use of castable properties. Therefore, the control of castable construction of the amount of water, the use of castables is very important.
