Alumina Magnesite Refractory Castable Application
❉Aluminum Magnesium Castable Suitable for Ladle Lining
1.Castable alumina magnesite used in the inner lining has good overall performance and is not easy to crack and peel off.
2.Castable alumina magnesite used in the lining is used for a longer period of time, the safety factor is improved, and there will be no accidents such as redness and wearing a bag.
3.Castable alumina magnesite of convenient construction and short construction period.
4.Castable alumina magnesite the maintenance of ladle is convenient in the later stage, the maintenance cost is reduced.
Alumina Magnesite Refractory Castable Construction
1. Refractory Alumina Magnesite Castable Prepare for Work
(1) Ensure that the refractory castable is dry before use and has no agglomeration.
(2) Check if the pouring equipment is in good condition and it can operate normally.
(3) Whether the membrane is installed properly, whether the size of each part is reasonable, and whether the interval is even. The surface of the membrane is coated with a release agent to facilitate demolding after pouring.
(4) Prepare a suitable vibrating rod to ensure that the castable is vibrated and compact.
2.Alumina Magnesite Castable Mixing Work
1) Determine the amount of refractory castable based on the capacity of the mixer and the construction speed.
2) The amount of water added is generally about 4%-5% depending on the construction conditions.
3) Castable alumina magnesite is necessary to ensure good fluidity, prevent excessive dilution and excessive thickening, affect the use of castables.
4) The refractory castable after stirring needs to be used within 30 minutes. It is forbidden to use overtime and no fluidity.
3.Alumina Magnesite Castable Pouring Work
① When feeding, open the vibrating rod and vibrate while feeding. After the feeding is completed, shake it evenly to ensure that no bubbles are discharged.
② The bottom of the package is poured first, the bottom of the package is solidified before the mold is poured.
③ When pouring the wall, it should be uniformly fed continuously, and the entire wall should be filled in one time.
④ When using the vibrating rod, it should be moved slowly, not too fast or too slow.
4.Alumina Magnesite Castable Demolding and Maintenance
Alumina magnesite refractory castable can be demolded 16-24 hours after molding. The specific demoulding time is subject to the construction conditions and weather. The natural curing time after demolding shall not be less than 24 hours.
5.Alumina Magnesite Castable Baking
When baking, the temperature and baking time should not be too fast. For details, please consult the technician.
Alumina Magnesite Refractory Castable Precautions
1.Dates are marked when the castable is stored. The general validity period is three months. Please use it as soon as possible.
2.When the refractory alumina magnesite castable is stored, it should be protected from moisture and rain.
3. When the construction is stirred, refractory alumina magnesite castable is forbidden to enter the mixer and the quality of the castable is affected.
