Castables are generally used in places where high temperature is easy to wear, because castables are a kind of refractory material, its refractory properties are more prominent, and the integrity is better, the strength is also very good, for some more complicated construction The castable is still very good. Among our four seasons, summer and winter are very special, one is very hot, very stuffy, and the other is very cold. We talked with you about the precautions for the construction of castables in the summer. Today, let’s talk about what should be paid attention to during the winter construction?
The construction environment of castables is generally between 10 degrees Celsius and 30 degrees Celsius, but the winter is very cold. If the temperature is below 5 degrees Celsius, the following things should be noted.
(1) The precautions for the construction of castables must be clearly understood, and some must be kept in mind, including some mixing, watering, and sanitation, strictly in accordance with the above.
(2) The temperature of the stirring should also be noted. Generally, it is stirred between 60 degrees Celsius and 80 degrees Celsius.
(3) It is proposed that the castables are being put on the spot to extinguish some wood or coal fire, and the mastery is not less than 12 hours. What should be paid attention to during the construction of castables in winter? After the grounding, take appropriate preservative measures, and be kept fresh, preferably on the spot to maintain the conditional measure above 10 degrees.
(4) The demoulding time is not less than 2 days, and the casting material is being demolded to release the mold, and the demoulding does not stop the strong tapping. Also note that a certain amount of maintenance must be carried out after the spit.
(5) Be sure to pay attention to the oven as soon as possible after the maintenance.
The construction of castables needs to be noticed differently in winter and summer, but it must be noted that it is strictly in accordance with the precautions and cannot be carried out according to the groping of itself. If any of the above contents are wrong, it is also welcome. You pointed it out to us and we will make changes in a timely manner.
