Coal Injection Pipe Refractory Curing and Baking Construction

Coal Injection Pipe Refractory Curing and Baking Construction

①15 ~ 35℃ : demoulding 24h after pouring and natural maintenance 24h after demoulding.

②5 ~ 15℃: demoulding 48h after pouring and natural maintenance 24h after demoulding.
③<5℃：ensure that the ambient temperature is greater than 5℃, low temperature baking with mold, and the demoulding time is extended to 48h or 36h.
④ When the temperature is higher than 30℃,after construction, if left for more than 7 days, it does not need to be baked separately. Otherwise, the coal injection pipe should be baked at low temperature before use and put into use no less than 8 hours later.
