1) silicate refractory castable is suitable for watering and curing, so that the cement in the product in the hydration process of dehydration and hardening.It is particularly important for the maintenance of the high alumina cement casting hollow, because the cement in the high alumina cement castable products has a rapid hydration enhancement.And produce a lot of exothermic reaction, easy to make its surface crack.
2) wet curing should be covered and watered after the hardening of pouring section. Watering times should be appropriate to maintain enough moisture state of pouring material.
3) the steam curing speed of Portland cement refractory castable should be 10 ~ 15℃/h, the maximum should not exceed 20℃/h;The cooling speed should not exceed 40℃/h.
