Method of use of refractory castable in castable

1, lightweight high temperature castable in the pouring ladle, to test the quality of the ladle and the use of load-bearing times, whether it is the crane high temperature castable ladle, or portable ladle, every 2 months to check once, important parts to check whether there are cracks, deformation, expansion and so on.

2. Use a mixer to mix the castable, pour the castable into the mixture first, and add the coagulative dose of 5-3%. According to the hardening time to adjust, the general autumn temperature ≤25 ° C, can be increased by 5%, such as the temperature of the construction site can be increased by 3% when the temperature is ≥30 ° C, in the construction of certain time to reduce the loss, in the pouring must be connected to the speed of pouring to the specified part until completion.

3. Castable is mainly stirred by mixer in actual operation, and manual mixing is prohibited. If there is no way, manual mixing is adopted. However, the ground must be clean, the castable should add coagulant, the amount of coagulant added is 3%, which site construction can add 5% mix and add 8% PA80 glue quick mix, ** used up in 10 minutes.

4, before pouring, first make the anchor solid coated with a layer of asphalt and paint, when the pouring thickness is 250mm, it is appropriate to pour to the specified thickness, vibration until the density is completely dense.

5, the mold must be clean before the mold, in the mold to coat the mold with a layer of oil, inch mold.

6, winter construction, add salt or other substances as antifreeze, reduce the high temperature performance of the material, or do not take reasonable anti-freeze measures during winter construction.

Castable use method ** To share this, castable mixing is recommended to use a forced mixer requires that all mixing tools and mixers must be clean and free of debris.
