Making refractory castable

Refractory castable a granular and powdery material made from refractory material by a certain amount of binder. It has high flowability and is suitable for the unshaped refractory formed by pouring.Compared with other unshaped refractories, binder and water content are higher, so the fluidity is better, their application scope is wider, and the material and binding agent can be chosen according to the use conditions.The utility model can be directly poured into a lining body, and can be made into a prefabricated block by pouring or shaking the solid method.
Test method:
1: the use of immersion rod vibrator,Shock half barrel casting material,Produce a plane in 10 seconds,If not, water must be carefully added
manual testing
Pinch a pouring ball by hand, throw 300mm into the air, then grab.If the casting ball has the same shape (slightly flattened) and prints a fingerprint, the water is suitable.If the ball from the finger in leakage of concrete is too thin, can not use too much water.If the ball is cracked, the pouring material is too dry. Water must be carefully added.
Note before and after pouring
The setting time of this castable is very short.The maximum interval between the mixing finish and the vibration finish is 30 minutes.Vibration time shall not exceed 5 minutes.After casting, the surface must not be exposed to smooth, and must use polyester plastic cloth to protect them.Condensation produces a lot of heat. The outer and outer surfaces of the baffles must be cooled and watered continuously.Step by step vibration (a few minutes up to 5 minutes, in order to prevent segregation).Placed on the upper surface of polyester fiber sheet (expansion joints). Start a new paragraph, restart steps. An end of the burner in don't forget the last two paragraphs, to replace the castable is different.
Using a vertical separator
1 meters board made of 1 section.1 section includes 2 semicircular parts.To match the total length of the separator to the total length of the tube, the last two segments will be cut from 200 to 1000 mm.Note: the pouring way should determine the partition inside surface clean, no rust on the inside surface. Brush a layer of insulating oil.The outer tube of the burner is maintained in a vertical state, the cross section of the clapboard is placed in a special fixer and is fixed on the outer tube of the burner.Start vibrating at the beginning of the pouring.Step by step vibration (a few minutes up to 5 minutes, in order to prevent segregation).The speaker will start a new start, operation steps.Do not forget to replace different castables in the last two segments of the burner end.
