Don't hurry, don't hurry! The construction method of low cement refractory castable is introduced to you by the small series of Hubei Anaijie manufacturers!

(1) anchoring nail welding. A pistol welding gun is used to clamp the anchor nail with a matching anchor chuck and weld the water-cooled beam (column) according to the design spacing.

(2) Wrapping and surface treatment of ceramic fiber felt. The pre-added block ceramic fiber felt is wrapped on the corresponding water-cooled beam (column), and the ceramic fiber felt is tightly wrapped on the water-cooled beam (column) with z2 galvanized iron wire in a spiral shape, and then the hardener is sprayed on the surface of the ceramic fiber felt, and the felt surface is dried and hardened to form a layer of hard shell before pouring construction can be carried out.

(3) Template installation. For the appearance of the lining wall after pouring and the fumigation use of the formwork, the 4 mm thick steel plate is used to make the shaped steel formwork. The steel formwork is installed from bottom to top, and the lower end of the formwork installed after it is installed should be stuck to the poured lining wall.

(4) Mixing of low cement castable. Must use a forced mixer mixing, the use of clean water, water temperature should be 10 ~ 25°C; In strict accordance with the material instruction manual given the mix ratio

Row batching and adding water; In order to overcome the uneven particle size distribution of dry aggregates during transportation; It should be dry mixed for 1 min and then stirred with water for 4 to 5 min.

(5) Pouring. The mixed castable is quickly transported to the pouring site, and the castable is poured into the mold with a small shovel and a special lower hopper. When pouring the beam, the material should be cut from one side of the form to prevent gaps in the lower part of the beam. When cutting the material, it is necessary to prevent the wrapped ceramic fiber felt from breaking and falling off, start the vibrator after the material is filled, the material surface sinks in the vibration, and the material is added in time. When the castable surface no longer sinks or the surface grout no bubbles escape, the vibration can stop. The vibration time is generally 2 min. After the vibration of the castable, the surface of the column is not trimmed. After the vibration of the beam castable, it is scraped and formed with an iron trope before the initial solidification, so that the section of the castable lining wall on the upper part of the beam can meet the design requirements.

(6) Mold removal and repair, when the temperature in the furnace is 10~ 25°C, the mold can be removed for 8 hours after pouring, and the castable can be naturally preserved after the mold removal. The quality of the casting should be checked in time, and the general defects should not be treated, but the important parts and large problems should be repaired to meet the production process requirements.
