The vulnerable influence of refractory castable in construction

1.    The construction of pouring space is small, the construction personnel usually add more water in the mixing, so that you can make the refractory castable has good mobility, but also increase the refractory lining hole body,

reduces the compactness of the lining of the body, and its strength is reduced: the same, lining of the body vibration imperfect, will shorten the service life of refractory castable.

2.     Lining thickness, pouring a small space, many staple clouds between the die and the burner, pouring and vibrating, vibration bar operation very difficult, operation not skilled or not serious, refractory castable is vibrating imperfect.

3.     After pouring, without adequate maintenance, as the lining of the body low early strength, loose structure, often too late to sintering have damaged; the lining body warms up abruptly, sometimes burst.

4.     Winter construction, the ambient temperature is low the binder (hydration) hydration of incomplete or water, or pouring body cold, would seriously reduce the refractory castable strength or destroy its structure, and affecting the use effect.
