Refractory Castable Construction Process

The refractory castable must be stirred by a forced mixer. If the mixer has stirred acidic, alkaline, and light materials, it must be cleaned up before use, and 0.5 to 2 mm of asphalt paint should be applied to the heat-resistant grab nails.
Run the mixer first, add refractory castables and admixtures, dry mix for three minutes until the color is consistent.
Add the clean water for daily use in the proportion of 5 to 8%, first add two-thirds of the weighed water, stir for three minutes, add the remaining water according to the specific construction requirements, add water to the denser the castable Less
Stir to the following state to start pouring construction, the mixed refractory materials must be used up within 45 minutes
The casting construction part needs to make a wooden mold according to the drawings to ensure the construction size of the casting material
The template needs to be painted with release agent before installation
The refractory castable construction must use the inserted vibrating rod for vibratory pouring, and each point should not be too long to prevent particle segregation and vibrate until the surface is flooded.
Refractory material reaches the initial setting in four hours, the final setting in 24 hours, and can be demolded in 48 hours. After demolding, it can be naturally cured for three to seven days before entering the next oven.
