Which points should be paid attention to when using refractory material？

1.After pouring, if without adequate maintenance, due to the lining body early strength is low, the structure is loose, often too late to sintering has been damaged, lining up abruptly, sometimes burst.

2. The lining thickness of thin body, pouring the space is little, between mold and burner with a lot of cramp, pouring, vibrating, the operation of the vibrator is extremely difficult, operation not skilled or not serious, refractory castable vibrating false.

3.Casting during the construction of the space is little, construction personnel are often more mixing materials with water, to make the refractory castable has good liquidity, but increase the porosity in the refractory lining of the body, reduce the density of the lining body, thus reducing its strength (if refractory castable for chemical combination, add too much liquid binder, same adverse effects) : on the contrary, lining body vibrating close-grained, not also will shorten the service life of refractory castable.

4.When the winter construction, low temperature binder (hydration) hydration incomplete or not hydration, or casting seas, would seriously reduce the strength of the refractory castable or destroy its structure, so as to affect the use effect.
