Description of artesian castable

Artesia castable is a new type of refractory material developed in the 1990s.It not only inherits the low cement castable density high, has the good fire resistance performance, the anti-erosion performance and the wear-resisting performance and so on the merit, moreover in the construction does not need the vibration equipment but may flow, the self-curing compactness.Developed by zhengzhou zhongyuan honest material resistant general factory, metallurgical bureau luonaiyuan institute, steel research institute, angang, wuhan iron works and other units of large blast furnace tiegou self-flowing material, applied to some large blast furnaces in China to achieve satisfactory results.

This artesian material construction speed is fast, the iron ditch life is long, overcomes the vibration material because of the vibration caused by the construction speed is slow, the iron ditch quality is poor, the iron ditch life is short and so on the flaw.At the same time, the self-flowing material with its excellent construction performance will be widely used in other industrial kilns, such as the overall casting of heating furnace, soaking furnace, rotary kiln cooler and burner parts, etc., its service life will be doubled compared with the traditional castable.

The flowability of artesian castable is characterized by the fluidity after mixing.The artesitic value reflects the artesitic property of castable, which can be used to measure whether the artesitic material has proper construction property and stable physical property.The artesian value is small, the material fluidity is poor, and the dense filling cannot be reached during the construction.When the flow value is too large, serious particle segregation will occur in the construction of materials.The expert thinks, artesian value should be in 50 ~ 100% inside, with 80% left and right sides is optimal
