When we use refractory castable construction, we generally use dry refractory castable, so in the process of construction, we need to do the batching, mixing and maintenance of these situations. Below we will be divided into the introduction: First of all, look at the ingredients, refractory castable in the factory has been prepared for the finished material, we only need to add water and high aluminum cement in the process of mixing. Use 85% of the finished material, add 15% of high aluminum cement, and then use 15% of clean tap water.

Also take into account the weather situation, according to the weather changes can be made to adjust accordingly. The amount of water can be appropriately increased when the temperature is high. (Note: The high can not exceed 18% of the water) followed by mixing, mixing equipment should be used with the appropriate capacity of the blender. Remove all debris from the mixer before mixing. Pour the finished material and high aluminum cement into the mixer in proportion, stir for 2-3 minutes to make the finished material and high aluminum cement fully stir, add the corresponding proportion of clean water, and then stir for 5-8 minutes. Until the castable color is consistent. It should be used within 30 minutes after discharging. Prevent the material from initial coagulation due to too long a time interval, affecting the quality of the project.

After the construction of wet maintenance 24-48 hours can be removed mold. Require 72 hours of maintenance after mold removal. The quality of refractory castable construction determines its service life, so attention should be paid to the above situations.
