High temperature resistant castable is a cement-based mortar specially prepared by factory by adding admixtures and admixtures to aluminate cementing materials and special aggregates with good fire resistance. The product has good construction performance and durability, can be used for a long time at 500℃ high temperature environment without cracking phenomenon. High temperature castable has been widely used in steel converter track, kiln track grouting projects. Involved in chemical industry, metallurgy, building materials and other industrial fields. So how to use high temperature castable?

(A) Basic treatment and support mold:

1, high temperature castable foundation surface chisel wool, and clean it. The components (such as steel pads) bonded with the base stock will be cleaned of rust and oil.

2, 4~** before the pouring seat slurry, wet the surface of the high temperature castable foundation, and there shall be no water when pouring.

3, the baffle should be strictly supported to prevent leakage.

(2) Grouting:

1, add water: according to the ratio of 3.1-3.5kg of water per bag (25kg), add water to stir, if the construction does not require greater mobility, the water consumption can be reduced accordingly.

2, mixing procedure: add a specified amount of water in the mixing bucket into the blender, part of the dry material into the bucket mixing, and then pour the remaining material into the mixing, the time from start to end should be controlled in about 3 to 5 minutes.

3. When stirring, the blades should move slowly around the perimeter of the barrel so that the dry materials adhering to the bottom of the barrel and the wall of the barrel can be mixed; The stirring blade shall not be lifted above the liquid level of the base stock to prevent air from entering the base stock.

4, when pouring, as far as possible from one side of the injection to facilitate the discharge of air between the bottom plate and the concrete foundation. If necessary, tools such as bamboo can be used to guide the flow. The pouring shall be carried out continuously after the beginning without interruption.

(3) Maintenance:

1, with a wet straw bag or cloth covered in the poured stock, and sprinkling water maintenance, 2 to 6 times a day.

2, the curing temperature should be above 15℃, the curing period is 7 days. If the site temperature is low, the curing period can be extended appropriately.

3, winter construction needs to take insulation measures, mold removal should be carried out after the completion of watering, and continue to maintain after mold removal.

(4) Packaging and storage

High temperature castable with moisture-proof packaging, net weight 25kg/ bag, shelf life of 6 months; Store in a dry and ventilated room, avoid moisture and use as soon as possible.
